2005 Silverado: Rear Drum Brakes ?

Is this item in regard to the 2005 Silverado a mistake?:

   Front disc/rear drum anti-lock brakes are standard on all models
   except trucks with Quadrasteer.

http://trucks.about.com/od/2005chevytrucks/a/05_silverado_nf.htm

Rear drum brakes? This sounds like a giant step backward. The Monroni
sticker on my 2004 Silverado shows that 4-WHEEL DISK BRAKES are standard
equipment. The rear disk brakes on my 2004 Silverado have completely
eliminated the traditional problems that I had with the rear drum brakes
on my 1990 Scottsdale: Out of round drums caused by park brake clamping
and park brake slippage. I thought that the 4-wheel disk brakes were a
tremendous improvement.

Is it possible that GM has gone back to putting only drum brakes in the
rear of its 2005 Silverado trucks?
Markeau - 16 Sep 2004 17:58 GMT
Yes rear drums for the new trucks but not suv's ... something like the
disc's were getting excessively chewed up from debris or something
thus requiring premature replacement ... This was recently discussed
on the Light Duty forum at

Unless they got to a double piston caliper they will have nothing but troube. I
have a 2004 and have had the brakes replace under warranty . I usually never
replace brakes till 60,000 miles as i do all highway driving.

What was your mileage when you replaced them?

Randd01 - 16 Sep 2004 23:49 GMT
I had 33,000 miles on it whn the first caliper froze up. Then shortly after the
backs were prematurely worn out at around 35,000 miles. In my opinion I think
the pads are too small. I don't know what the problem is with the calipers but
I know a few peopel that have had a few freeze up also. And I also have a
ffriend that has a 2004 that had to have all the brake lines replaced to the
back brakes because there were internal blockages of some sort fromt he
factory.  But he wore out his back brakes in 12,000 miles. Another friend  with
a 2001 has had the brakes done 3 times  under 50,000 miles. The dealer told him
it is because the  antilock sensors were dirty. BS!!
GMC Gremlin - 17 Sep 2004 23:58 GMT
The problem is this. They will literally last forever "IF" the owner takes
care of them. This means greasing the slides. The pads are like 1" thick and
the rotors are so beefy I can't see them EVER being too thin to turn.

Wait, the full-size trucks don't have dual-piston calipers?  Even the
S-10 had dual-piston calipers up front.  The 98 and later 4x4s do
anyway...
Randd01 - 17 Sep 2004 10:08 GMT
What i was getting at was double pistons means larget pads . Drums have a lot
more service area of shoe then disc pads have.

Well, you thought wrong.  The rear disc brakes on full size trucks (New
style body), have been nothing but trouble.  Especially trucks that are
used in a lot of off road applications, or muddy, dirty situations.
Personally,
as a mechanic that makes my living fixing the stupid things, I'd prefer that
GM not bring back the drum brakes (very little goes wrong with them), but
in the interest of putting out a more reliable product, drums are the way to
go in a lot of situations.

You can get either drums, or disc brakes.  Your choice.

I'm afraid that the next phase of GM's retro brake technology might be
the elimination of the hydraulic system and a return to the primitive
mechanical mechanisms used in the early 30's. Mechanical four-wheel drum
brakes will undoubtedly be the next innovation. If GM were to top off
this antiquated drum-brake system with a pull-on "emergency" brake, they
could set braking technology back by over 70 years.

Here is a review of GM's newest braking system:

"Keep in mind, that drum brakes have improved drastically in their
technology and performance in just the last few years. I'm not clear on
exactly what that technology is, but this is what I'm told, and I'm just
parroting it. The 1500's new drum brakes are the largest ever installed
on a light-duty truck, and they make the new 17" wheels a necessity."

The implication in this article -- as well as several others -- is that
GM has created a vastly superior braking system for its 2005 trucks by
switching back to oversized drum brakes in the rear. And these are not
just ordinary oversized drum brakes, mind you. These are drum brakes
that are so big and massive that they mandate the use of the new
17"wheels. Best of all, the money that GM has saved by using the
old-fashioned drum brakes on the rear allows for vast improvements in
the front disk brake system.

They don't "die".  You may be thinking of drum brakes that don't
work when you go through water.  In this instance, I'll give the
disc brakes the nod.  But because of the clearance issues between
the caliper and rear rims, the position of the caliper (front of the
rotor)..etc..the rear disc brakes have a tendancy for the banjo
bolt that holds the brake line to the caliper to loosen up...the
rocks and crap that get between the caliper and rim can either
damage the rim/caliper, or get into the caliper and pad area and
cause premature wear on the pads.  Sorry, we see it all the time
and have to repair them.  We have two options for off road trucks,
we install a pair of mud guards "in front of the rear wheels" and/or
special shields that bolt onto the rear calipers and they help deflect
crap away from the caliper area.

Ian
JBDragon - 19 Sep 2004 00:54 GMT
I see it on the Ford Trucks with Disc brakes in the Rear.  The left rear
side the Caliper is on the front and has a Shield, and right rear is mounted
in the back with No shield on the F250 Super Duty trucks.  The Rear Brakes
hold up quite well!  Even with lots of Caked on mud/Dirt on these over
loaded Work trucks I see.   I think if Chevy did the same type of thing by
Installing a Shield around the Caliper to help block some of the Crap it
would be a better way to go then switching over to drum brakes once again.

Of course there could be the other reason of the Parking Brake having a lot
of problems on the trucks.  It's still using a single large round shoe back
there.  The Parking Brake never feels that firm like most people are used
to.   It ends up getting left on and driven around on until it starts
grinding away.   I've replaced quite a few for something that should hardly
ever need to be replaced as it doesn't get used except when the truck is at
a dead stop.

I know GM has made calipers in the past where the ebrake engaged the normal

problems.

It's not really a good idea to put a huge load on your parking pawl...
If I ever have to park on a steep hill, I set the parking brake.  I
also set it when I'm on the boat launch putting the boat in or taking
it out.

The last GM tranny I pulled apart (all be it a transaxle) had a BAND - not
pin of any sort - the way it should be. If ANYTHING it should be a BAND and
THEN a pawl, incase the band fails for some reason. Other than that - just
like drum brakes - emergency brakes have no point in modern society.

and what about those of us that prefer a manual trans? are we not modern?

so what are you going to do when your main brakes fail? just throw the trans
into park??

Dearest Trey,

> and what about those of us that prefer a manual trans? are we not modern?

I had made this exception in a previous post. I thought this post had been
narrowed down to but a few who would remember my context, welcome to the
fun.
A park should simply be put into manual transmissions. There is no reason
the fork couldn't engage 1st gear into an immovable gear cast into the case
or whatever.

> so what are you going to do when your main brakes fail? just throw the trans
> into park??

Design your braking system so in most instances of failure you have at least
a front and a rear, or both fronts and a rear. The proportioning valve in my
'90 GMC Jimmy separates the front/rear of the truck. IIRC the '91 Skylark I
just sold separated the P/S front & D/S rear, and vice versa. This system
(skylark) gives you roughly 50% braking power. The truck (a worse design
IMHO) give you variable stopping power. If the rears went, it would stop
pretty well. If the front went, it would stop not-much-better than a parking
brake (drum brakes are AWESOME!!! lol).  But in either event this allows the
braking mechanism to be used entirely as they were meant, in a hydraulic
fashion with all braking surfaces applicable in use (not just one pad).

And as for thinking you can stop ANY vehicle with an "emergency" brake
(which, BTW, GM calls a PARKING BRAKE) is sheer lunacy. You'll only "knock
off" a few MPH and you might as well just crash straight into them and enjoy
the carnage.

And as for what I would do if I was dictator:
I understand the desire for redundancy in the braking system, since it's a
big safety thing. My take is make STAINLESS steel lines, and have two
braking systems INDEPENDENT of each other. With stainless lines, unless you
drive around in salt water they should never rot out. The only reason that
they *should* fail is because of blunt-force trauma, and if you designed it
correctly, one system getting damaged should put the other "far away" so it
wont take them both out at once. IE the only place that lines of the two
systems should come close to each other is at the wheels and at the booster
(though not the master cylinder, two of those)

Au contraire...the e-brake was the difference between getting stopped and
explaining to my neighbor what I could have done to his truck when my old
Sierra decided not to stop in reverse.

I'm glad I fixed mine...it came in very handy that day.

'84 Sierra, 6.2, 4-speed automatic...questionable power brakes!

Now, on the other hand. If you were going even 20MPH an "emergency" brake
would probably get you down to say... 15MPH in any appreciable distance. As
it does in both my Jimmy and in my mother's '99 Malibu. I USED to drive my
'85 K5 around with just the e-brake, until I fixed my brakes (my
suggestion).

Unless there's somthing wrong with the rear brakes or they are not
properly adjusted, the parking brake can stop a vehicle just fine.
Most I've seen can lock the rear wheels up totally (not a good idea if
you're using it to stop).

You must drive go carts. Rear wheels might have 20% of the braking power,
and parking brakes have probably less than 1/2 of that, but no more than
1/2.

My truck is not moving if I have the e-brake on.  Yes, the rear brakes have
20% or less of the truck's total stoping power, but that is still stoping
power just the same. If the brakes fail, th e-brake will still stop the
truck, it may take 80% longer, but it will still stop.

Unless Chevy changed, it only presses ONE shoe into the drum, so it could
only have 1/2 of that 20%. So it doesn't get better than 90% of your
original breaking power.

The GM parking brakes have ALL used both the leading and trailing shoes
for the E-Brake. Ever notice that the E-Brake lever goes between the
adjuster and the shoe? With the way they are set up a properly adjusted
drum brake will stop a vehicle faster and with less pedal force than
disc brakes of comparable size. WHY? Discs do not have any provision to
use the motion of the vehicle to increase the stopping power of the
brakes, they depend entirely on the hydraulic pressure behind the
pistons.

Being stupid and overheating them then putting the E-Brake on without
letting them cool usually does it.

In the entire time I have owned or repaired vehicles (from motorcycles
through class 8 trucks) I have NEVER had a warped drum that was not
caused through operator error and even then there were only a very few.
Now rotors on the other hand, how many would you like, I scrapped about
50 a week because of warping and cracking, plus the lovely rust
delamination that some cheap rotors were known for.  There are only two
real reasons why disc brakes were developed. One was to reduce brake
fade on race cars due to heat build up inside the drums, the other was
to reduce unsprung weight and rotating mass on the axles.
Most auto manufacturers used them because they are cheaper to
manufacture and service than a drum brake system.

GMC Gremlin - 25 Sep 2004 18:07 GMT
SO lets see......
Less fade due to heat. So they are there if for some emergency you REALLY
need them. Like a panic stop at 70MPH?
They continue to work well when muddy.
The components on a well-designed system are easier to replace.
There are fewer springs/lever/cables/JUNK to break/seize/go wrong.
They have greater stopping force too...
Yup. Inferior design written all over it.

I own a 1972 chevelle, four wheel drum. It faded at every stop, even when I
wasn't "racing" and panic stops were SCARY.

Drum brakes would be best described as "lame" - but not in the sub-culture
sense. In the sense the word was intended for. Just like an old finicky
pain-in-the-a.s man who you don't like to talk too and wont shut up and
thinks he knows everything and can do everything. So since he knows
everything and can *DO* everything, he supervises you because he is too
decrepit to actually DO WORK. (Sounds like drum brakes, too lame to WORK
RIGHT)

P.S. The only reason drums are more expensive is because of the rube
goldberg "mechanism" within them.

Well I never was good in math with all these percentages, but I know I
could lock the rear wheels up in any of the vehicles I've ever had
with an emergency brake... percentage of braking ability doesn't make
a damn bit of difference.

I think there must be somthing wrong with YOUR emergency brake.

And no... both shoes are used in GM emergency brakes.

When you apply your brakes, the weight of your truck is thrown forward onto
your front wheels. Not only does this make it EASIER for your rears to lock
up (which mine can) but it gives them even LESS stopping power, making them
all the more pointless.

The point was that the emergency brake is strong enough to lock the
wheels.  The trick is to NOT lock the wheels up when you're trying to
use it to stop.  Very easy actually.

I'm used to the air-brakes in the semi that I drive everyday... so
feather-footing the brakes is somthing I'm used to.

No - what I'm actually saying is that cars should be designed with true
braking redundancy.
But hey - what the hell do I know.

Not all of them! Rear disc brakes are optional in 2005.

Optional? Anyone who chooses to get drum brakes needs to have their head
examined. They are nuts, especially if you pull a heavy trailer or 5th
wheel.

So I guess that anyone who owns an older truck with drums in the rear can't
stop with a heavy trailer? Wrong! If the rear drums are sized appropriately
to the usage of the vehicle it will stop as good or better than rear disc
brakes.

70% to 80% of the braking force is to the front brakes anyway. So no any one
who wants rear drums is not nuts.

They are easier to maintain aslong as the caliper doesn't freeze up, have a
lower cost of owner ship, and they stop better, doesn't matter if 70% -80%
of the stopping is done by the front. if it has disc in the back also, the
stopping power is that much more efficient than drum. Atleast this is what I
have noticed with disc brakes.

When you have the option of disks, yes you are.
But I'm not saying that drums on an old truck are useless. You need
something in the rear while you save up for a conversion kit.

Well put Gremlin. But I'm a cheap bastard, I wouldn't convert from drum to
disk cause you would also have to change the proportioning valve, time I
wouldnt want to spend.

Do you happen to actually "work" on vehicles for a living?
I suspect you don't...otherwise you would know that the
drum brakes on GM trucks have rarely given any problems
over the years.  But the rear disc brakes that appeared in
99 on the new trucks have given all sorts of problems.  I know
this because I work on them all day long.

As far as I'm concerned and I'll bet many other folks that
buy trucks and use them as work trucks.....bringing back
the rear drum brakes as an option will be a good thing.
For the person who owns a truck in the city and drives
it much like they would drive a car...then the rear disc
brakes will work well and won't give them many problems.

Ian, where would I get either of these items and what is the cost?  I
plan to take my S-10 off-road again and maybe it would be a good idea
to install one or both of these...

As far as I know, they don't make them for the S-10 trucks.  We don't
seem to see any problems with them.  If I remember, I'll check and
see if the manufacturer makes a version for the S-trucks.  These items
are not made by GM, but by an aftermarket place.  GM does approve
them.  GM does make their own version of caliper shields, but the price
is about 10 times as high, and they don't appear to be as large or robust.

Ian, did you get a chance to check on these?  I know the S-10s with
rear discs have issues with caliper slides freezing up on the
passenger side rear tire.  Just want to head off problems before they
start...

Oh... and even when the rear drums in my 1990 GMC Jimmy  are working
"properly" if I get them muddy they no longer do...
