Will I have to bleed all the brakes or just the caliper that I'm replacing (or maybe just the rear brakes)?

 

If you don't let much air into the system, just the one you're working on.

 

You should only have to bleed the rears, if that's all you're working on, as the front and rear brakes are 2 seperate systems, hydraulically.
Just to reinforce the point, DO NOT DRIVE YOUR CAR AT ALL UNTIL YOU BLEED THE BRAKES. You WILL crash into something. That's guaranteed.

 

Ok. I think I can deal with just bleeding the rear brakes. Hopefully everything goes well. I had trouble getting the caliper off last time so I'm going to spray it with liquid wrench.

 

I through mine half way across the driveway because I got pissed and wanted it to loosen up. After repetitive tries of doing this (and seemingly no result) I found the biggest pair of vice-grips I could, a crowbar, and vice. Used the vice and vicegrips to hold the piston and the crowbar to then the entire caliper (less the piston). It took a few hours but we got the piston out. Then I rebuilt both rear calipers.

6 months later I bought four new calipers, rotors, brake lines, and fluid and rehashed everything again...

The parking brake can be removed off teh caliper relatively easily, just a couple nuts. (two if i remember right).

You'll have to rebleed the new caliper when you hook it up.

 

i just rebuilt my front calipers and one was stuck in so bad i couldnt get it out or move it at all. I was in luck though, since the piston had a lip around it so i took an air hammer to it with a blunt chisel and took it out. My friend was amazed that i took it out like that. All i did was try to get under it the best i could and put the chisel in the lip of the piston, then with a few quick bursts with the hammer, it came out.

 

My caliper is seized onto the upper mounting stud. I've been spraying it with liquid wrench and hitting it with a hammer and various objects for the past three hours but it won't budge. Any suggesstions on getting it off?

 

use heat....mini propane torch works wonders

 

I ended up buying a bracket from a junkyard. I also bled my brakes, and they're very spongy. I hate bleeding brakes, I've never been able to do it right and I follow all the instructions. I'm going to take it to a shop tommorrow to have them bleed the brakes. It's worth the $60 to me.
