From http://www.540i6.com/inspectionchecklist.html it says

"Remove and install front and reat(sic) disc brake pads, check overall
thickness. "

Presumably - they are simply re-installing the old pads if they are thick
enough?

If I'm getting someone else to do this I can just have a quick look behind
the wheel or let a "proper" check be done as part of MOT?

Kwik Fit etc want 161 for new pads all round!
My local rough garage want 45+50 (supply+fit) or (20+25) fit only.

Fronts are easy.  Turn to full lock (first one way then the other) and have
a look / measure.  Rears probably require a ramp, or at least the wheels
taken off (probably being swapped anyway as part of an inspection II).

Have a good look at the disks themselves at the same time for deep or uneven
wear.

If you cruise up and down motorways they can last ages, rushng round town
and they soon wear out.

Well I wouldn't take them off if they are thick enough.

MOT will not check thickness, only efficiency.

I thought they pulled out of this business due to their well established
reputation... and were sticking to tyres and exhausts, although perhaps the
AA took them over.

Which sounds about right.

See www.eurocarparts.com for aftermarket parts.  Unless you are racing or
live in the Alps, the BMW ones are a bit of a luxury on a car this age.

The MOT testers manual (http://tinyurl.com/ba7h6) says that pads of less
than 1.5mm thickness are a reason to fail the vehicle.

It's a nice theory, but it also includes brake shoes. And on most vehicles
these can't be inspected and measured at MOT time. Nor can the pad
friction material be measured accurately either without removal - and
dismantling is forbidden.

Accepted. My post was really to make the point that Mark wasn't correct
when he said pad thisckness wasn't part of the MOT test. I only knew
because mine failed on that back in November.

I recall there being a specific reason for removing the pads and
reinstalling them.  Maybe it was something obout greasing the contact
points, I don't remember exactly.  I am 100% certain that BMW would not
remove the pads and reinstall them if all they needed to do was take a
peek at the thickness of the pads.

I'd say the real purpose is to clean the dust from the callipers - you
don't need to remove pads to check the amount of friction material
remaining.

The MOT doesn't check 'service' items. If the pads have enough 'meat' left
and pass the brake test that's it. Although a kindly tester may advise
they are close to replacement time. But in reality all that's needed is
that they pass the test on that day. They could be worn down to the
backing a week later...

You also need to check the front discs' thickness. These need replacing
about every other pad change. Rears last rather longer - although the
handbrake should also be cleaned and adjusted at inspection time.

FWIW, BMW brakes are pretty easy to work on. If money is tight it's
certainly worth DIYing - get an experienced pal to help the first time.
Eurocarparts are a good source for OEM quality spares at a fraction of BMW
prices.

Blimey!  £161!!

Pads must be about £50 for fronts and rears.

It's really very easy to do....

Want me to do it for much less than that!?
