    Interesting(?) Brake question

    Yesterday my husband replaced a rear rotor and front brakes on the car. Now the last time I had replaced the front brakes, was about 2+ years ago. In the meantime, I had to replace the rear ones over the summer (which were replaced the same time as the front 2+ years ago), but the thing is that the rear ones are wearing much faster than the front. This doesn't makes sense to me?? Shouldn't it be the other way around?

    In many other cars, you would be correct. LT-1 f-bodies are a little different. The rear calipers were borrowed from the Corvette which was a lighter car. The result is that the rear brakes are a little undersized, the pads wear quicker than the much larger front pads.

      Many of my friends as well as my own car, have found that the rear brakes actually don't work all that well and I still have the same pads and rotors with little if any wear (LT1 f-body's)-before I did my brake upgrade.

      went I installed my 3.73 in the rear they have a break in period and when I wanted to stop the tires from spinning in the air, no matter how much I pushed the pedal they wouldn't completely stop spinning.

        That may be an indication of light brake use. If you push these, you'll find that they will wear quicker even though they aren't that effective.

        Remember, stopping power comes from the front brakes. The rears are more for slowing the car. Discs are actually horrible for holding power, that's why they don't work holding the rear wheels in a brake torque situation.

        The other thing that wears out the rear brakes is power braking. You all know what that is........ holding the brakes and punching the throttle for big, smokey burnouts.

          Thanks for the brake info though. Interesting to learn!

            My rear pads needed to be replaced at about 50K miles. The fronts are still the originals with 85K miles on them, and the pads are still at about 50% of original thickness. This seems to be the more common situation.
