I put these on a few months ago and got new pads and the rotors turned. I put them on the bracket and the pads were on the rotor so tight the wheel wouldn't turn. Keep in mind the same way for both sides. I put a new master cylinder on there so I just got around to bleeding the system. Still nothing tight as hell on the rotor. So I took off the pads on the passenger side and pushed the pedal to push the piston out to see if it works. Now the piston is a good 1-2inches out and with all my effort the piston won't go back in the caliper. Does that mean I have a bad set of calipers? They are off a GT stang and are used but I have no idea if they were good or not since I bought them used. Any ideas
Thanks Dan

You can't push them in by hand. You'll need a c-clamp to push the pistons back in.

yes of I used a c clamp in fact I broke the c clamp because I tried to force it in so hard

chances are the pistons(s) have poped out enough that now that you tried to put them back in.. that they may of went in at a angle and jamed..

I rebuilt a set of PBRs... and could push the pistons even with new seals in by hand.. also just this week finished rebuilding a set of calipers for a 914.. once again pistons went in easily by hand... OH and i'm not that strong :)

Just replaced mine.

I had some used and they pulled right real bad. Loaded calipers cost me 64.95 each. And they be good now. No more pull.

Dan I;m sorry but LMAO!!!!!!!!!!!

SHUT UP!!!!!!!!!!!!!! I hate this car and it now has stock calipers back on there until I can figure out why I'm so retarded and can't get the "Bolt in" PBR's to work properly

What year is your SC? Early models used a different front rotors than the later (93+) models. You'll most likely have to upgrade to the 93+ spindles (and rotors) in order to use the PBR calipers.

how tight is "way too tight"? Is it tighter than a guys bung hole at his first prostate exam? :D

he has a 94

It says Dead in his sig, and his 90 is sold. Maybe he doesn't have an SC at all!!!!!

Is it possible they have a check valve that you have to release?

I'd pull the caliper off the car, clean it out, dry everything off, and inspect the piston(s). With a dry caliper, the piston should move smoothly by hand. Measure the thickness of the pads+rotor and compare it to the gap in the caliper with the piston seated. Obviously if the gap in the caliper is less than the rotor/pad thickness, you have a problem. You'll have to turn the rotor or get a thinner one, get thinner pads, or get a larger caliper.
You are referring to the front calipers, correct?

i told him to try to thin out his pads he said i was craazy

front rotors have been turned already. I tried a different set of pads and still the same. I know people have put new pads when they have swaped so I'm on my own with this issue I guess

I just did front brakes on my car, new front calipers from NAPA $18 a piece. Make sure you clean the slides on the mounts and lube everything up real good.:D Rotors were like $30 if I remember right.

You know they require a different caliper mounting bracket, right? Also a different banjo bolt and bleed screw. Are you sure those are all correct?

everything is like it should be everything is PBR specific. The bracket all the bolts except the hub to bracket bolts are all mustang. The only tbird part I am actually using are the rotors and the two bolts for the bracket to hub everything else is mustang

With new rotors and pads, mine went on snug, but the wheel spun freely. Just to be sure, you might want to take the rotors to AZ or Advance and have them check them against a set of 94/95 rotors. I really think you have the wrong rotors or something.
