Thanks for any info

I learned this the hard way on a Sunday afternoon. Went to separate the calipers and they twisted, shearing this little o-ring in half. And you're right, they're not included in the rebuild kit.

So....

Go to Napa or Autozone and buy a complete O-ring kit with various sizes. I luckily found an open store that evening and one of the sizes worked perfectly. Just match them up and you're good to go. Never had any problems with it.

HELP!!!

So got my calipers powder late by a local shop(will start another thread about them later) and today while re assembling the calipers, I felt a grind when replacing the bolts that hold the caliper halfs together. So I instantly reversed the ratchet to pull the bolt out to see what was going on, and it locked the bolt. Now it won't turn any way I try to turn it. I checked the other calipers(the unassembeld ones) and found that there is dust trapped where the bolt threads into. My question is how do I loosen the bolt that is seized, also is there a way I can clean the threads for the calipers myself?

Sounds like some elbow grease will get the bolt out...

Anyone know what the four 17mm bolts are called for the rear caliper. I snapped mine off

17mm? On the sport brake rear caliper?

I'm not aware of any 17 mm bolts. I know there are two 19 mm mounting bolts and then four 14 mm bolts on each rear caliper.

Yes I’m sorry the four 14mm

If you have at least one bolt still intact, maybe you can try to source an identical replacement locally (I'd try Fastenal).

My buddy had to extra bolts laying around. Going to fastnel tomorrow to pick 16 of them. This diy suggested 80ft lbs is ABSOLUTELY WRONG. On the four bolts. High tighten and 1/4 turn after the caliper is on the car.
