i've got the stock 10.5 inch discs all around. i recently replaced all my brake pads, when i noticed the rear passenger ones were worn at an angle, and the new pads were at the same angle when i put them in. they also made a clacking sound, like the pads were jiggling around when it hit bumps, or rock the car on that side. thinking my caliper was bent or the piston was screwed, i replaced the caliper.
that got the pads sitting flat against the rotor, but the clacking is still there. i had put them in without the bushing that goes up by the mounting bolt because it was such a PITA trying to get it in there so i figured wth. so today, after many, many, curse words, i put the bushing in (i think the right way.)
in the diagram in my service manual, it shows the bushing being between the sleeve and the caliper, on the outside of the caliper, facing the car. i tried to put them in like this, but the bolt is the same diameter as the sleeve, and the bushing just slide right off. so i figured it had to have been the way i originally thought, that the bushing goes on the inside of the caliper, between it and the caliper mount (i think thats what its called, what it bolts to.) using a small prybar and a lot of persuasion, i managed to work them both in, but the clacking is STILL there!!! WTF??!!!

 

Many posts about this pad rattling. Its an inherent defect in the Delco-Morraine iron caliper design. The pads will always rattle even if you bend the tabs properly- and- the more heat introduced into the system form performance driving, the quicker the tabs will unbend and pads will rattle more.

My car stopped fine but I finally sh*t canned those brakes and built my own system from scratch.

 

gay. im assuming if i find a 4th gen rear with 3.42s or 3.73s, the brakes that come with it will not have this defect?
