rear brake problems

[jonah]

I'm having a problem putting my rear calipers back in place on my 1989 240sx. I've changed my brakes several times, but this time, there is too much pressure in the line i think, because i can't turn in the piston in AT ALL. whats the best way to fix this problem. thanks a lot.

Did you take the master cylinder lid off? Also, do you have the piston tool that fits on a 3/8" ratchet?

It sounds like you have a seized rear caliper. You can try breaking it loose with vice grips, but chances are you just need a new caliper. $20-$25 at most junk yards.

Did you open the bleeder screw?

When i got my rear brake pads the guy at the store asked me if i ever did them before, because what you have to do is twist the cylinder to the right, kinda like ur screwing it in, instead of just pushing it back.

Sometimes you can use a pair of large needle nose pliers to catch the notches on the piston to rotate it. To break it loose, open the bleeder and try using a large c-clamp to nudge it loose. If you use the pad on the clamp's threaded end on the piston it will almost always rotate clockwise as you compress it.

Vice grips are a lot easier than pliers. I've actually broken a pair of pliers trying to turn old rusted pistons.

You are correct. The ones I've used are the needle nose vice-grip type, not the small wire cutter types. You will need a very beefy plier.
