What is the Factory Rear Brake pad thickness?

I did search and I did advance search and I also used keyword and tag search.

Keywords = brake, pad, rear thickness

Searched only in 8th Gen forum.

I read first dozen posts and some people say their rear pads are at 8mm. Coupe owner.

I have a 09 Sedan and had my B1 service today. oil and tire rotation.

Front brake pads = 10mm ( as new the tech said)

Rear brake pads = 6 mm ( he said the rears are not 10 mm, but start off at 7mm)

I want to validate what he said because of some posts that I have read indicate a higher value for the rears.

My car has 8700 miles on it.

I did mentioned the brake noise and when I drove home, the noise wasn't as loud as before.

Thanks MJC!


So. just under 9k miles and 2mm from pad gone if we round up high on the thickness scale.

so 18k = another 2mm loss.. 5mm

27k = 3mm

but i doubt the pads will wear down that way. Less mass, more heat. probably quicker wear.

Any brake pad specialist here?

I have a new set of the rear pads (ending in A40) and a new front pad set (ending in A60) and I put the digital calipers on them and the rear pads are 9.0mm thick and the fronts are 10.9mm thick factory new. I just measured the pad part (not the backing).

Is having 3.2mm left on the rear brake is unacceptable for a 1 year old car with 12k miles?
Because I just got home from the dealer for the first B1 service and was told that my brake has 8mm left on the front and 3.2mm left on the rear. I asked the service guy about how many more miles can my rear brake last and he told me that is vary but I can last about 20k-30k more miles. Was he just telling me BS?

I was told by the service rep it was 9mm for the rears. Have an '08 EX-L rear pads were replaced at 20K miles (Nov'09). Just had a 1B service last week pads were down to 4mm after 12K miles. Was told that the dealer did not replace with the updated pads in Nov and they will replace these under warranty when it gets down to 2mm. Oh the fronts are still ok.

If you have 3.2mm left with 12K of mileage, then you probably won't get another 6K out of them. They are 9.0mm brand new and the service limit is 1.0mm, so that leaves 8.0mm to use up. You've used 4.8mm in 12K, so 3.2 left leaves you with 2.2mm of actual pad to use before they need to be replaced. That's approximately 5-6K of miles left on them.

I honestly have not experienced any brake problem in my 09 sedan since I bought it. Haven't even changed the brake pads yet. I'm at 20,000 no problems yet...

nocharmars, if I were you, I'd remove a rear wheel and look at the brake pads to see if the prior owner upgraded to the last generation brake pads (A40s). If s/he did, you'll see a wire-spring clearly visable between the rear pads. If you don't see that, I recommend you buy a set of replacement pads (or your choice of aftermarket pads) and install them now.

What you're trying to avoid (obviously) is the backing plate on the old pads coming into contact with the rotors. You should hear the wear indicators first, but if for some reason you don't notice the sound, you could go from an incidental expense for brake pads to perhaps significant $ for brake rotors.
