OK, so I didn't have a great night last night. During my front-end overhaul, I upgraded to Bisteins, and 911S aluminum calipers. The caliper pistons came out without issue using my compressor at 90psi, but they wont go back in
The calipers are off the car, the pistons are positioned properly at 20 degrees, and straight in the bore. I used new brake fluid as reassembly lube, and have installed new seals. All four go about 1/2 way in and stop. Any ideas.............. I don't want to drop $200 on new stomski pistons just to find out the caliper bores are really what's bad. -Justin |
