CJ Brake Caliper Questions
I have the front calipers off as I am in the middle of a complete brake
overhaul.
My questions are: While I have the calipers off is there any way to A:
Insure the quality of the rubber seals AND B: Any way to flush the
calipers out from the inside while they are off?
The fluid running through them was pretty nasty!
Thanks

Well... The only sure way to make them squeeky clean is to remove the
piston (usally with compressed air but make sure you put a cloth
or sponge in front of the piston), then clean, re-o-ring, and assemble.
You can flush them out, mostly. It just takes more brake fluid
and some hose. In through the brake line fitting and out through the
bleed screw till it's clear.
Resist the urge to use spray cleaners or gas, that will contaminate
the piston and ring and put you back to the rebuild stage.
And if you do take the piston out, be careful setting it back in.
Some are real easy to get crossways.

Don't forget to keep your fingers out of the way when blowing out the
pistons with compressed air. It's painful just thinking about it.

Re: CJ Brake Caliper Questions
Keep an eye on the piston, and back off on the pressure as it starts to
come out. If it stops moving, then try a little more pressure, but not
much. If it gets stuck, then push it back in so it is straight, and
try again. If you are careful, this should be a simple process, but it
is possible to screw things up pretty badly. The piston can get stuck
crossways on the way out, just as easily as it can on the way in.
