Pistons in calipers,, Compress
So I have a couple
of calipers... They might be seized...
I just would like to See if I can
use something more than a screwdriver
to compress the piston back into the
caliper.
Is there a cheap(inexpensive)
method.... anybody has derived
of to even apply force to cause
the pistons to recede into their
bores?????
I was thinking of a couple of
ideas but, don't really feel like
reinventing the wheel.....
or even a tool... I can purchase
that doesn't "break the bank".

I use these; but C- clamps work great too.
12 in. Ratcheting Bar Clamp/Spreader
I usually leave the inner pad in the carrier and use that to seat the clamp on. Open lid on M.C.

Hi Goldie88
Working in the remanufactoring business of autoparts, I will not advice you to try repair your old calipers yourself. To many Things can give you troubles later on. If they are started to corrode and are stocked, even if you change sealings, you will have leaking soon again. It is a safty part... My best suggestion (and, at the end of the day, probably also cheapest), - get yourself a pair of remanufactored calipers. :-)

Dig it.....
Yeah, gone are the days of rebuilding
calipers and wheel cyclingers..... honing them out... etc....
So it is a dual piston caliper.... I have to ask...
cause I have only messed with cars that have
single piston calipers...... When you
squeeze one piston in..... (if the other
piston in the caliper is not clamped)
will the other piston move outward????
Do you have to clamp them both
at the same time?
I had seen people wedging a screwdriver
in against the rotor to move a piston inward......
on these(volvo - utube) cars........ Seems like not even pressure
on the piston..... what do you's think?
THanks, G88

Well, OK, but the "old" fluid won't cause any damage backing up a little. And by opening the nipple there is a risk of allowing air in the system necessitating bleeding. If you are just replacing the pads, a little prying onto the caliper won't hurt a thing... I like to keep it simple.

"How much do I know about brake fluid and ABS systems?" I am sure not much compared to you; you sound like an expert. However, working on brakes, ABS and not, for some 40 years and never having had a problem backing up some brake fluid by pushing the piston back gives me enough comfort in the practice not to worry about it...
