Rear brake caliper problems.

I put new rotors and had to get a new caliper because my old one was locked up and over extended. I installed the new one, tightened the brake lines on caliper and hooked e-brake cable to it. We bleed the brake but the caliper will not compress. What's going on?

If it is anything like mine you have to twist it while compressing. Can't do the normal c clamp it in thing

It will slide on the rotors and brakes. It's the piston in the caliper won't compress on the brakes...

Yes on mine to compress the piston in you have to twist and compress at the same time.

I was lucky and looked it up before I did mine. I would have busted the piston just shoving it in there lol

Look my problem isn't getting the caliper back on the rotor. My problem is my caliper is loose on the rotor and I have no pressure on the brake pedal. We bleed that brake lines for about 30 minutes and still no pressure.

So the piston is compressed and won't come back out is what you are saying? Not sure about that never dealt with it. Only thing I would say is just try to keepbleeding them until you get pressure.

Open the bleeder screw and leave it open (shouldn't take that long) it will fill itself. Once its dripping out the bleeder close, refill the master, pump brakes and bleed, in fact bleed both side rears. See if that makes a difference.

I finally got it somewhat to compress. But the brake petal hardly feels like there's anything there. Got it good enough to drive it out of my buddy's shop. I'm gonna need to do a bleed my brakes day sometime. What's the procedure of doing a correct bleeding job. Isn't it like master cylinder first, then RR, FR, RL, and FL?

If you haven't bled them yet that's probably your entire issue especially replacing the caliper.


The 2 person bleed will work (google it) but I just bought a pressure bleeder. Crank it up to 15 psi to get past the ABS controller and crack the rear right caliper till it runs clean, check pressure, then left rear, then front right then front left. This ensures there is absolutely zero air in the system vs the 2 person method which is not 100%.
