brake calipers
 

how can i fix seased brake calipers.

Rebuild them :bigthumb:

Go to Checker, Schucks or Kragen and get a rebuilt one. I got 2 new front ones for $37 each with core.

Ok thanks. I checked it out and it rounds out to about $207.

I want to rebuild them but how do I get the pistons out if they are seased.

Sometimes they are siezed so bad that it's next to impossible to get them out without destroying the piston. Swapping for a rebuilt caliper might just cost you less in the long run if you have to replace pistons, and it's a heck of a lot less frustrating!

take channel locks and see if u can wiggle them back and forth (not in and out) to see if it loosens them up a little. sprays some wd40 on there too to help some.

PB blaster works great too, but if they're ceased, they might not be rebuildable from dirt and such getting between the piston and the bore and messing everything up pretty bad. Are the rubber boots still intact?

yea dude ususally when you get seased up calipers, u need to get new onew or rebuilt ones...dont try to rebuild it your self....unless you have a lot of time on your hands

I'm hardly a mechanic and I rebuilt 6 calipers in my life, it takes an hour at most and like everything else. You can't half ass it and make sure you do it right.

Its pretty simple, take them off, open them, everything from the kit goes in only one way.

Its pie.

If you have a compressor just hook the comp tube up to the caliper's fluid whole and shoot those pistons out. Or will he have to screw them out?

I don't want to seem to be an arse, but what do you mean by siezed? Are you having a problen getting them to compress? If that's the case then you need the tool to compress them. Must be used to compress the pistons when replacing the pads. The tool can be had at most auto parts stores. It is a cube with 5 slot configurations. Costs about $5.00 as I recall. You might try it before replacing calipers that might be OK.

I've seen more than one FC - mine included - where the outboard pistons had basically fused themselves to the caliper. I tried everything, including compressed air, but they wouldn't budge. Any more force would have destroyed the piston and/or the caliper, so at that point, I swapped them for rebuilts.

I fixed them today. i basically had a set of calipers laying around with no pistons in them I had taken them apart awhile back to paint and rebuild but found that they too were siezed but managed to get them out four of them where bad. so I put the good ones away.
So today I took my calipers off and managed to get four more pistons. I bought a rebuild kit for the front calipers and rebuilt a set worked out pretty good I'll have to bleed them tomarrow though.

i really dont understand why everyone wants to use air to blow out their pistons. its stupid and dangerous. it takes little effort with channel locks. all u do with air is risk injuring yourself, have a fun [hell] time making all the pistons come out at once, and blow brake fluid everywhere

You can put a piece of wood in-between the pistons and blow compressed air into the caliper until all 4 come out enough so that you can pull them out by hand. No big mess.

The point of this thread is to see if anyone new of a way i could remove SIEZED caliper piston that's all.
When I took mine apart I still could not take out two of them. even with channel lock or a pipe wrench. my car has been sitting out side under a car cover for a year.

Compressed air is the CORRECT way to remove caliper pistons. You are not supposed to blow them right out of the hole, though!
