mra32 Posted January 25, 2009 Report Share Posted January 25, 2009 I just did the 94+ rear brake upgrade and when I did I noticed that basically nothing was really corroded that bad, except the knuckles (The cast piece that the brakes, shock, hub, trailing arm, lateral links, and monoleaf all would connect to). The corrosion was so bad that it looked like it came off the titanic. I think that all the corrosion is making the calipers sit at little cocked from the rotor, so the pad is not engaging the rotor correctly. Is there any way to buy new ones, or am I supposed to cruise junkyards looking for one thats not too bad? Also what else would make the calipers not be aligned properly? And any way to make it straight again, short of taking it off and milling it? EDIT: I found them on GM Parts Direct. $96 for the left side and no listing for the right. Its listed as 90-94. Does anyone know the difference between those and newer ones? They happen to be more expensive too. Thats a little expensive. Quote Link to comment Share on other sites More sharing options...
BXX Posted January 25, 2009 Report Share Posted January 25, 2009 The knuckles are all the same, and being cast iron, its gonna get rusty... blast them down and problem solved.. Quote Link to comment Share on other sites More sharing options...
Crazy K Posted January 26, 2009 Report Share Posted January 26, 2009 The knuckles are all the same, and being cast iron, its gonna get rusty... blast them down and problem solved.. yes and no. having compared a couple, it seems the strut bolts are a different sizes on 96+ ones. but i don;t see a difference on 95 vs 94 vs 93 vs 92 vs 91 etc etc. i would attack and clean them rather than replace them.

But the pattern is the same, so they are interchangable. And no, not all 96+ are different. I've compared mine from my 96 CS to my 90 TGP, even the bolt holes are the same size. Possible Gen 1.5 rear knuckles have the different bolt size Quote Link to comment Share on other sites More sharing options...
mra32 Posted January 26, 2009 Author Report Share Posted January 26, 2009 OK, thanks for the response. BUMP for this question. Also what else would make the calipers not be aligned properly? The only other thing i can think of is bent hangers. Quote Link to comment Share on other sites More sharing options...
mra32 Posted January 29, 2009 Author Report Share Posted January 29, 2009 Oops I'm clearly retarded. The aux spring bracket was interfering. All is better. I dont know why i thought it was crooked, maybe it was being poked in a weird direction to make it like crooked? I dunno all is well. Well at least with that part of my car.
