remove them from the suspension or remove them from the car?
I believe I did it.
It's really complicated:
- take them off, but don't take off the brake line. _________________ "Rule: Turbo's make torque, and torque makes fun." (C. Bell)

Why do you want to avoid bleeding the brakes? It is so easy to do. I know people say that you can install clutch cylinders without bleeding (I never do it that way) but I would not do it with brakes. Brakes are too important. Bleed them any way you want, but bleed them. _________________ 87 924s

Brake fluid should be changed every 2 years.
Rubber brake hoses should be replaced every 10 years. _________________ White 87 924S "Ghost"

I've changed the brake fluid recently, but now one piston is stuck in its hole. That's why i want to remove this caliper. |

pull off the caliper thats stuck and plug your flex hose with a cap to advoid losing fliud.rebuild or replace the defective caliper .after its installed open the bleed screw and let it gravity bleed...ALWAYS keep an eye on your fluid resevoir and dont let it empty!after the bubbles disapear close up your bleeder screw.now you are going to have to bleed that side that you just removed the caliper.doing it this way will avoid you haveing to bleed the complete system.  _________________ Doco "where am i going and why am i in this handbasket"author unknown

If you are going to try to install a seal kit in the stuck caliper, make sure that you get the piston freed up before you remove the caliper from the car.
You can use the car's brake system to blow the piston free by removing the brake pad on the caliper piston side, then stepping on the brakes. Since the other three calipers will move the brake pads a very small distance (limited by the rotors), the rest of the fluid will be directed to the caliper with the stuck piston, and should blow it loose.
Make sure that the caliper is on the car (travel limited by the rotor), since the piston will move suddenly and quickly with great force.
As DOCO wrote, you can gravity bleed the brake lines if/when you remove a caliper. I start with the caliper installed, piston not fully retracted, no brake pads, and the bleed screw removed for maximum flow. |
