9 Bolt PBR Calipers

Does anyone have part numbers for the proper calipers for the 9 Bolt rear with the aluminum PBR calipers / Pads / Rotors. I want to make sure I am ordering the right stuff. Thanks

You will most likely get a new china part, if you can, rebuild your factory calipers. (if they really need it) Mine have 250k on them and are just fine.

Just a heads-up. The 9- and 10-bolt PBR braking systems are interchangeable. To that end, you may find some of the info/part numbers in the following link beneficial: https://www.thirdgen.org/forums/faq-...iscs-89-a.html

Re: 9 Bolt PBR Calipers

Right: calipers, pads, brackets, etc. interchange. Backing plates do not. But if your 89 already has those, you won't have to worry about them.
