So i have a friend with a 92 eg and his passenger side pads seem to wear a lot faster than his driver side and wear out extremely fast. He told me that he has new rotors and pads and his car shakes when he brakes and that when he pulled off his pads, there was uneven wear on the pads. I am suspecting a bad caliper. Does anyone have any recommendations?

 

caliper piston or the slide pins are seized. those are the only causes of uneven pad wear.

if his car shakes when braking the rotors are warped or not installed correctly. if he is doing it himself he missed a few things. (like the seized caliper).

make sure the hub surface is clean and free of rust. if it's rusty and full of crap the rotor will not sit flush to the hub and cause vibration while braking.

 

Pretty much what he said. Make sure he uses something like NAPA brand "Sil-Glyde" to coat the slide pins with, if one is seized it will cause an uneven braking surface to the rotor, putting a hell of a lot more strain and heat on one end of the pad.

 

so the shaking while braking has always been occuring even after he installed new rotors. still rotor problem? or hub problem?

 

This might be a stupid question, but before installation of the new rotors did your friend remove the yellow rust-inhibitor glue that they coat new rotors with?

Also, if a rotor is overheated and is warped, it's not going to magically go back to being true. You will have to have the rotors lathed flat and true again for this shake to go away. This is NOT a hub problem.

 

yes we did. brake cleaner does the job...but yea idk ima get more details from him and maybe repost with an update thanks!
