I need to rebuild my caliper and dont have the extra $40 a caliper to just get remans. Anyway can someone tell what kit i need off the autozone website? I doesn't say for a 4 or single piston caliper. It only says for a 2" or 1 7/16" piston. I tried to check the manual for piston sizes but i didn't say anything.
Thanx

 

just to make it easier i listed the two options form the site.
1991 Mazda Rx7 Front Caliper KIt
WITH 1 7/16" CALIPER PISTON
WITH 2" CALIPER PISTON

Which one do i need for the four pistion front calipers?

 

If your car is not turbo and has five lug wheels and four piston calipers you will want to use the 1 7/16 inch repair kit.

 

Ok will do. Also the TII had larger pistons in the calipers as opposed to an na with the big brake option package?

 

N/A and TII 4 piston calipers the SAME.

The 2" caliper brakes are (from what I can tell) the single piston brakes, and Auto Zoo doesn't know the difference between what cars came with what in their computer. I ordered 2 sets of the 1 7/16 when I rebuilt mine recently (one for each caliper).

 

how much do these run? I need a new rear caliper.
