What is the most miles we can get on a set of rear brake pads that would warrant changing the pads? My rears are semi-metallic and currently have a little over 30,000 miles on them.

I think I went about 60k on my original rear pads. and they still had some meat left at that. As you know the rear only accounts for about 35% of the stopping force.

i had 110 k before i replaced the brakes. guess it just depends on how hard you are on them

also depends how far and kind of conditions yu drive them in

Actually, the rear accounts for much less than 35%.....probably more like 5%-10% of the braking.
All of it is in the front, to speak of.
I usually have to change my front pads about once a year. I drive like 25k miles in that time period.

I have 95k on the original rear pads and still running on them. I changed the front pads this year with 82k. Fronts still had about 5k left on them. I must be real gentle on the brakes.

I got around 100k out of my rear pads, now i have axxis pads, and still look beefy at 135k.

Just changed mine for the first time yesterday at 48k on my 99

you guys should drive in NYC. I maybe get 30k on my pads and i brake very gently.

You aint kidding, I replaced my rear ones twice already and I've got 75k
