those replacements they come from oreillys that's why i was asking about the 9c1 because i'm told they are wider.where do you get them fromwere those the stock calipers or replacements if they were replacements they prob got it wrong theres alot on these cars that are diff from stock ss to 9c1 and alot of parts palces dont know wtf there talking about when it comes to the b bodys
The FRONT 9C1 caliper is wider.
You guys would have an easier time working on your cars if you would stop dreaming up and oversising the MINOR 9C1 and Impala SS differences. It's ALL just a Caprice. Get over it, understand the MONOR differences and then you can effectively work on your car.
Far as the Cardone/PBR thing. The original calipers are PBR, Cardone is a REBUILDER meaning they take used original parts, clean them up rebuild them and resell them.
I don't have rear disc brakes, but if that was a front caliper I would say that the piston is not bottomed out in the calipers. Ask the SS/9C1 guys for their opinion to be sure.I use a large c-clamp and an old brake pad (over the piston) to even out the force. It doesn't look cocked in the pics, but you should check it.
thanx for your help .i can't beleive it has been over a week and i still don't have brakes ,wowI don't have rear disc brakes, but if that was a front caliper I would say that the piston is not bottomed out in the calipers. Ask the SS/9C1 guys for their opinion to be sure.
You might try putting some compressed air into the hydraulic fitting and see if you can move it back out to try again. Put all the old brake pads in the caliper or a block of wood in there because you don't want the piston to pop all the way out. Use one of the old pads and your c-clamp to evenly spread the force on the piston and go slowly. Make sure that it doesn't get cocked.
Also, as previously mentioned, check the part number of the pads to make sure that you have the right ones.
Also, as mentioned previously, the 9C1/SS functional difference is for the FRONT calipers/pads. The rear caliper difference between 9C1 and SS is only a cosmetic difference.
If all else fails, take the calipers, the brake pads, and a rotor back to the parts store and ask them to show you how it fits. Take along all boxes for the new parts.
