im slowly going through my new to me '91 to get it prepped for an upcoming DE. I went to check / change the rear pads and to my surprise the pad had almost zero material left on them. What I'm trying to figure out is do I need new calipers too?
the brakes were upgraded to "sport brakes" though I'm not sure from what year, or even if it matter? The front brakes look good, rotors look new and I just put on xp12. The rear rotors look ok on the front face but the rear face look like they've never seen friction. They're just a rusted mess. What I find odd is the back (inboard) pad looks more worn than the front pad (outboard). I would think if the back of the rotor looks like it hasn't seen a brake pad for decades then the inboard pad would be less worn.
So 2 basic questions:
1. Should I replace the rear calipers?
2. How do I know, or should I care what year the brakes are from so I can pick the correct rotor?
this is the rear face of the drivers rear rotor and matching pad.
Dear lord, is that your ******* rear rotor??? Looks like the Titanic wreckage.
Look, stock single piston brake calipers are based off of Newton's third law. As the piston pushes against the outer surface, the caliper should slide on it's pins, therefore pushing (pulling?) the rear pad against the back of the rotor. If your pins are bent, rusted, or corroded (I'm guessing they are), they'll be seized to the pins, and the only force on the pad will be from the piston side.
But to answer your question, judging from the photo you posted, you need new hard brake lines, soft brake lines, calipers, brackets, rotors, pads, and probably control arms, sub frames, and a new chassis.
