I just thought I would let everyone know about 84 - 87 rear calipers from amazon. 8 years ago I bought reconditioned rear calipers from Napa auto parts. They never leaked but the park brake would not function and I could never get the pads adjusted correctly. Believe me I checked every thread I could and did a lot of searches. I had those brakes apart every winter for the 8 years. Someone mentioned a month or so ago that amazon had them available. I ordered a pair and got them a few days ago. They are Chinese of course but lets give it a try. removed the napa ones and compared them to the new ones and the exact same casting number. checked the operation and what a difference. the napa ones were stiff and not smooth when park leaver moved. Ok I install and bleed the new ones. My service manager friend at the chev dealership said the correct way to do the original adjustment is to take a cresent wrench and manually apply and release each calipers park brake until the pads grab and release the rotor. Then adjust the cables so they just move off the stops and the adjust so they just touch the stops. reinstall and torque the wheels. Wow my brakes are awesome. The amazon calipers are good .
