Brake pistons stuck

[padams2002]

Hi,

Just tryed to replace my front brake pads. I managed to get one brake pad in. But on the other side of the disc when one piston was pushed back the other poped out. Now I cant push either of them back at all. Tryed levering hard with screw driver but they will not budge.

Now I cant use my car because I cant even fit the old pads back in.

I think I might have a siezed piston.

Anyone got any ideas on what I can do?

Cheers

The problem with levering hard, is that the piston will go back at the wrong angle and jam. To push it back, but keep it parralell to the sides, try to use a large screw driver, but twist it instead of levering. Look at the angle of the piston, you have to get it going back straight.
Also another tip is to try and slip the old pad in, and then try and slide one of the shims in, and then the second one and gradually open up the gap.
Some pad changes can be an absolute nightmare, and some are a 10 minute job.

Thanks. I\'ll try that tomorrow.

I used a quick release \'G\' clamp could just about get both pistons at the same time, worked well.

Or try one of these.

Also make sure you take the cap off your brake fluid bottle before you start  trying to push pistons back. Otherwise the brake fluid has nowhere to go.

If you\'ve topped up your brake fluid while your pads are worn, you may find brake fluid spills over the top of the bottle when you push the pistons back, so beware.

So would there be not any truth in Bleeding back the calipers on
cars fitted with ABS some thing to do with pump damage?
Not trying to scare but could be an expensive mistake if you have
 long travel to get them back in?
Anyone else heard this, or anyone even do this, just a thought!
