Brake pad mm indicator....what does it mean?

I just got back from the dealer in which they performed the maintenance interval for my car. On the bottom of the work order, they have the following:

BRAKE PADS GOOD FRONT 8MM REAR 6MM

What does this mean? Does this mean that my rears are wearing faster than the fronts? Also, at what point in MM should I replace the pads?

Thanks!

Well you 1st need to know how thick they were to start off with... some front pads are bigger right off the bat.

FYI: My rear pads wear faster than the front.. Crazy

Mine were at 9mm front and 7 mm rear at the last check-up. That means my rears are wearing a little faster.

I think you should replace them when they're 3mm or less.

Front pads start at 11mm and rears 9mm..

I believe minimum on both is 1.6mm.

I'd hope they measured the rear pads using the INSIDE pad.

I've never seen one NOT wear the inside pad faster than the outer on the rear discs. If the pads freeze in the carrier, then all bets are off, they usually destroy the pads (stick on) or the outer pad stops working altogether.

Usually, if you go by percentage, the outers will be at about 25 to 30% and the inners near the bottom by the wear indicator are usually at 5% to essentially zero.

On the front brakes, you'll usually see the RF (passenger) wear slightly more than the left.

What about noise? What kind of noise will indicate a brake change?

Looking at the above three posts you can conclude that your front and rear pads are actually wearing even and have worn 3mm

Most pads have a metal "squeaker".. once the pads wear to a certain point there is metal to metal contact hence the horrible sound.

I wonder if you'll need to replace the rotors when the wear indicators start squealing...

Squealing is caused by a small piece of metal designed for the purpose of warning when the pads are worn out. So turning the disc is not required just because of the squealing.

3mm is correct for replacement. That is where our gauges say RED is at 3mm. Anything above is fine.
