Dumb Brake question.....

wetherbymr2 · 05-14-2009, 06:46 PM

When you step on the brakes....the front calipers grab more or the rear? I know the E-brake is the rear....but i'm trying to figure out where all the noise from my brakes is coming from when i apply them....

like i said...dumb brake question.

Stock brake bias is front heavy, like most cars. Rear brake bias causes instability when braking from high speed, back steps out and then the car spins. Locking the fronts just causes understeer and flat spots on the tires. If you have brake noise, it can be either one. Did you check to see if the pads are worn to the indicators? That's easy to fix, just replace them. Anything else is going to take more time and money.

Thanks for the info.

chk my other posts though (about the noise). New pads all around. Had the bearings replaced all the way around and when i picked up my car was told either my calipers were bent or my rotors warped. just trying to figure out which set of rotors to replace first.

Ah, that's you. Like I said earlier, I'd bank on the rotors before the calipers. Lift the car (to remove wheels) and see if you can find any visual signs of warped rotors. If it's bad enough, it'll be easy to see, if not, you can look for uneven light reflection, indicating angled surfaces. Beyond that, I can't think of much else, sorry.
