They want to turn my rotors

Milleron - 09 Dec 2005 17:03 GMT Hi, My '03 Accord EX has 35K mi., so I asked my local service center to check the brake pads when they were changing oil. They found (and showed me) about 10% remaining on the RF and 40% on the LF. Rears were fine. They suggested replacing the pads and TURNING the ROTORS. They say that one ALWAYS wants the rotors resurfaced and that they don't charge any more whether or not that's done along with pad replacement. I go to this place because they've demonstrated their honesty to me on several occasions.
I know this question has been asked and answered before, but I'm hoping for an up-to-the-minute opinion from you experts.
1 -- If the rotors do not appear scored, should they be resurfaced the first time the brakes are redone?
2 -- The car drives, handles, and brakes perfectly. Is there any reason for concern about the uneven wear of the front pads?
Thanks very much.

One does not "always" want the rotors resurfaced. Resurfacing reduces their thickness, which means heat dissipation is worse, and the life of the rotors is reduced. Seems like peopel have more problems, not less, after resurfacing rotors, as oppposed to leaving them be.
One of the manual specifications for rotors is a certain minimum thickness. After reaching this thickness, the rotors have to be replaced. They're bringing rotors closer to this and so also shortening their lives.

I don't know how much questioning you want to try to do of these guys, but if you think they'll talk honestly to you, ask them whether they checked the rotor thickness. If it's uneven, then that might be a reason to resurface the rotors. Similarly, if there are indications the rotors are warped, that might be a reason to resurface (or replace) as well.
If they won't discuss something as simple as rotor thickness, go to another shop.
You can google and I bet get a lot of good information from the internet on this as well.
> 2 -- The car drives, handles, and brakes perfectly. Is there any > reason for concern about the uneven wear of the front pads? Could be a lot of things. A good brake system flush might solve it. It bears watching but I wouldn't fear for my safety in such a car at this point.
Is the car steering okay? Are the tire pressures checked every two weeks, especially when the seasons change? Are the tires wearing evenly?
Lots of little stuff to watch.
Eye Indo - 09 Dec 2005 18:46 GMT Do not know if this is of any value, but does not some re-surfacing remove the glaze on the pads ? When I replace pads, I do not necessarily re-surface, but I do use a sandpaper pad and give the rotors a quick "quasi re-surface". Maybe not necessary at all, who knows.
Sparky Spartacus - 25 Dec 2005 15:18 GMT > Do not know if this is of any value, but does not some re-surfacing remove > the glaze on the pads ? How would resurfacing (rotors) have anything to do with glaze on the pads?
Why would new pads have a glaze in the first place? IIRC that's something you avoid by breaking in the new pads properly.

The wheels have been balanced and rotated per the service manual. I don't check the pressures twice a month, but I've never found a difference of more than 1-2 psi between the two front tires. I think I do a pretty good job of keeping them about 2-3 psi over spec and equal to each other.

Years ago went with a friend to drop off his BMW - needed rear brake pads. The Hans und Fritz act behind the service counter said something similiar - I unloaded on these crooks. Ended up replacing the rotors for my friend.
You never ever turn a rotor unless it is hopelessly warped or grooved. These crooks at the stealers are doing harm when they do this. I have maintained several accords for something approaching 700K now - never had to have any rotors turned - on one occasion had to retorque the lug nuts because the apes in a tire place overtorqued the lug bolts and warped the rotors - retorquing them properly took most of the braking shimmy out.
If this dealer or stealer as I call people like this are willing to pull this trick - beware - one of the fav stealer tricks is to cut CV boots - that is a pricey repair. When walking through dealerships I always keep a very tight grip on my wallet - have got a couple of the sales sharks to bite - tell them I always hold on to my waller in high crime areas.
Yeah there are good dealers - know a couple of small town ones that are good people but find someplace else to work on your honda - no telling what tricks this crowd will pull. Oh would I like to have it out with these clowns.

butch burton - 11 Dec 2005 03:58 GMT My first accord - an 80 now has over 300K on it - rusty as hell but the rotors on this puppy have never been turned. I would much rather spend my money on something beneficial to me - I really do hate crooks of any stripe. Guess the guy in the franchise muffler shops with the popeye arms and 18" channel locks that he uses to "test" your exhaust pipes is my fav sleeze ball. Used to live in Mpls - was a franchise muffler shop on Lake Street in S Mpls - still remember this neanderthal with the channel locks - have to stop in some of the muffler shops around S WI and see if they have a similiar critter testing pipes.

There may have been problems with your original pads/rotors (hi/lo spots, excessive gooving, etc). Did you ask for specific details? Since you pads were unevenly worn, it's likely your rotors are, also. You don't want to be putting new pads on unevenly worn rotors. Don't forget you're dealing with the brakes, your last line of defense between you and a hard place. Turning the rotors shouldn't cost that much. Do you really want to cut corners?

It is rare that pads on the same rotor wear evenly and my left front pads seem to always wear out before the right side does. What are unevenly worn rotors - don't exist - grooved, warped or scored - no way could this happen on a vehicle with only 35K on it and rotors not dug into by worn out pads.
Never ever turn rotors unless they have big problems - that is unless you are a chiseling dealer trying to lighten your customers wallets.

I don't want to cut corners on my brake jobs but I don't want to screw up the rotors by resurfacing them either. Not resurfacing the rotors will not lead to any catastrophic brake failures. If the rotors are worn, scarred, corroded or severely warped, then replace them.
If the pads are truly wearing unevenly, the place to start is by cleaning and inspecting the calipers and sliding surfaces. Usually just cleaning and lubricating them will solve the problem. Only exception is if the pistons are not moving freely in the cylinders. Then rebuilding/replacing the calipers is in order.

I too think it's extremely misleading to assert that a failure to resurface rotors at every brake pad change is "cutting corners."
The chances of a catastrophic failure /suddenly/ occuring because the rotors weren't turned after 35k miles is, ISTM, a heckuva lot less than something like driver inattention causing an accident. It's so small, in my estimation, that we may as well factor in the effects of turning the rotors at every brake pad change and so making them so thin that they don't dissipate heat correctly and warp prematurely. That too increases the chances of an accident.
Elle Original owner, 1991 Civic, 172k miles, never had the rotors refinished. The thickness is well above spec. Runout and evenness are probably off. Brakes work fine. One rotor has a score on it. I brake a lot with the engine and otherwise see the brakes as "workhorses."
Al - 10 Dec 2005 19:14 GMT dissenting opinion here --
Often on this NG, people vigorously defend Honda engineering and design and admonish posters to read the manual and follow factory recommendations for maintenance. When Honda manufactures a new car it uses new freshly turned rotors and new brake pads. The perfect brake job would be to replace everything to the way it was brand new, ie. new rotors for the new pads. Second choice would be to resurface the rotors so that they are as good as new.
If you place a new pad on a new or freshly turned rotor you will notice that they will mate up with no preceivable gap (yes there will be a microscopic gap which will be largely gone in the first 400 miles of careful breakin time). By the time a pad is worn out the rotor will be both glazed and may be worn slightly. There will often be a preceivable gap between a new pad and a used rotor. The new pads have to wear first to conform to the high spots on the irregular surface of the used rotor. A new pad will slide easily over a glazed rotor but on a turned rotor it will feel as though it is sticking - in other words you can feel the friction (friction is a good thing when braking).
I have put new pads on without turning the rotors and have not had a problem, but I am not fooling myself into thinking that this is a first class brake job or that the new pads are likely to last as long as the first ones did, or even that stopping power is fully 100% of what it was designed to be.
It is unfair to call anyone a crook who is advising you to do a first class job and keeping your car up to the specs the engineers set for it. The cost of turning a rotor is not much, in fact the cost of a rotor is not much. Try to be aware of the difference between "good enough" and "perfect". Good shops want to stand behind their work - it's hard to do "good enough" work and stand behind it.
Gene S. Berkowitz - 10 Dec 2005 22:29 GMT is fully 100% of what it was

Many mechanics balk at this suggestion, because it means more effort, though not much more time, from them, for a pretty low-cost part (actually cheaper than the pads, per wheel).

if you're getting uneven wear, i'd check the caliper operation. if you're in the rust belt, it's possible that the calipers need servicing at this mileage, in which case, do it yourself. if you're not confident, sign up for an evening class at your local community college. otherwise, check out tegger's excellent "how-to" on his web site.
for the time being, it's safe to replace the pads and keep driving until you've done your course. replace the pads yourself - it's /real/ easy if you follow the procedure in the book.

You're right. My brother's always done his own pad replacement, and he thinks that this DIY job can save an owner more money per hour of labor than any other single repair.
Do you know if there would be more than one OEM type of pad for this Accord -- i.e., does Honda sell both metallic and nonmetallic Honda-brand pads? If so, which is better?

tubeguy - 10 Dec 2005 03:20 GMT If it's aHonda Dealer, I would not be surprised. When I took my new 2004 Pilot into my Honda dealer for an oil change, they offered to "clean" the brakes for only $100 extra. The odometer read only about 8000 miles (and those were probably about 90 % highway miles, i.e., the brakes had not been used much). I told them "no thanks". I have heard similar stories from other Honda owners, where the dealer performs unnecessary service. Too bad because I think Honda makes great vehicles, but their dealers are out to take all the money they can get from the owners. Angus

> Hi, > My '03 Accord EX has 35K mi., so I asked my local service center to [quoted text clipped - 18 lines] > > Ron Back when all the cars had drum brakes, the drums had to be turned every time the shoes were changed because they were always chewed up, warped, etc. Then they switched to disk brakes and the disks didn't show any wear at all if the pads were changed before they completely wore out. The brake shops, as a matter of course, did their best to convince owners that the disks had to be turned as a matter of course because the drums always had to be. For some unknown reason, this still seems to be going on.
The official Honda answer (page 19-13 of the '00 TL FSM) is that the rotors should be inspected for damage and cracks, cleaned thoroughly, then measured for runout. They should be resurfaced on the car if the runout is out of spec, replaced if the thickness drops below spec after resurfacing. If the runout is in spec, they should not be turned, it just shortens their useful life.
Personally, I've been driving cars and light trucks with disk brakes since 1972 and have yet to ever have (or need to have) a rotor resurfaced.
SoCalMike - 11 Dec 2005 06:30 GMT > Personally, I've been driving cars and light trucks with disk brakes since > 1972 and have yet to ever have (or need to have) a rotor resurfaced. same here. and th eonly pair i replaced was on a VW rabbit- the kind that fell off when the caliper was off. replaced em cause i felt like it... and they were $15/ea.
Stephen H - 11 Dec 2005 16:47 GMT ASE standards is right up with your opinions. I appreciate all your inputs, but I stand at the other end of the job.
I didn't use to turn rotors unless there was a pulsation, but now I always turn rotors unless they are at the min spec. I view rotors as a wear item, and the prices have come down on them quite a bit in the last few years, but the prices of pads are going up... hmmmm I only get paid to do the job once, and doing everything possible to prevent a customer form coming back with a complaint is critical to our business. It amazes me to stand at a lathe and watch a rotor that had no pulsation take 2 cycles on the lath to straighten itself out. I've seen cars with one hell of a pulsation clean up in one cut and others with no pulsation take three to clean up. Cleaning up a rotor usually only takes off .006 thousandths off the rotor. Hardly anything in the life of the rotor. I want you to leave with the highest quality job you can get from me, with no problems. So from a shops point of view it's about quality and warranty.
If you choose to not have the rotors turned and insist on this, then the work order may read something along the lines of "shop not responsible for any squeak, squeal, or pulsation that may occur"
OH BTW I passed the L1 Test.

[quoted text clipped - 4 lines] > Cleaning up a rotor usually only takes off .006 thousandths off the rotor. > Hardly anything in the life of the rotor. I see a Larry Carley article supports your data, stating that a cut of 0.002 inch is the min required; 0.008 inch is the max that should be taken off. (I know you're certified and all and have more experience doing brakes; I am mostly posting for the archives and to be complete.)
To add some perspective: A 91 Civic sedan's rotors start at 0.83 inch thickness and have a min spec of 0.75 inch. So with about 0.006 inch coming off at each resurfacing, figure at most 13 resurfacings before the min spec is reached. (Wear by itself on my never-resurfaced rotors had their thickness down about 0.02 inch, to 0.81 inch thickness, after 150k miles.)
I would think brake pads wouldn't need to be replaced more than 10 times in the life of a Honda, using OEM pads. Plus, I expect most Honda owners do not keep their Hondas beyond 200k miles. That's maybe four brake pad changes.
Assuming the car exhibits no serious brake problems, and that the resurfacing is free like the original poster said, I suppose then I'd consider resurfacing the rotors at every brake pad replacement.
But as a DIY-er who feels she has a pretty good handle on brake operation, and who has no tools for turning a rotor, I'm inclined to leave my rotors be until I see evidence of, say, deep scoring or serious warpage.
OTOH, if anyone knows where OEM rotors may be had for under $25 each, or can suggest non-OEM rotors, then I'll hear you out. I might like to put those on my car come summer.

The real answer is that resurfacing the rotots IS standard and customary for a proper repair. Having a fresh surface lets the new pads bed in properly.
Do you HAVE to do it? Welll no. and I dont do it all the time either.
I would be suspicious of a shop that DIDNT say that.

I've found simply hand-sanding the discs with 50-grit emery cloth does almost as well, but you have to be very even with your sanding (no power tools!), and it's hard work.

I used to think turning rotors was a bad idea, but I've changed my mind.
And home mechanics don't have brake lathes, do have time, and aren't likely to yell at themselves if things don't work perfectly. Hence my sandpaper suggestion.

At the time I was thinking peple would be more likely to blame the part than themselves. :)
