my brakes are tight
 

my question is how hard should it be to push in your calaper pistons on a 4 piston calaper and is there a easy way to do it.
:wallbash:

If you mean how hard is it by hand, you won't be able to do it. Take an old brake pad and place it over one side of the pistons. Then place one end of a C-clamp over the pad and the other over the back of the caliper. Tighten. The only thing to watch for is the pistons sinking in cock-eyed. Push until they are close to being flush or until you can get your new pads in and over the rotor.

Another method is to buy new calipers.

Your brakes are hella tight, holmes.

Assuming your brake lines are still hooked up, when using this technique be sure to remove the MC reservoir cap and cover with a rag or something- the fluid you are displacing has to go somewhere.

I think I remeber reading somewhere that on the 4 piston set up you have to have a little twist action when pushing it in, not 100% sure though.

The MC cap has a vent doesn't it?

I have a 90 model t2 and when i replaced my rear pads i had to twist the piston back, clockwise. Thats how the service manual said to do it.

okay, for the front brakes, use a BIG channel lock + old brake pad and clamp, if everything is ok, it should go in easy.

for the rear, you need the tool, turn and push, with the cheap brake square tool thing.

thanks guys u really helped :bluesuit:

Yes it does, but it's sized to accommodate the normal fluid/air displacement during operation- which is very little.
Pushing the pistons all the way in is gonna move a lot more fluid.

HSGDMF I wish I would've known this last night at 11PM when I was working in the dark, pounding on it like hell to get it to retract. Ah well, either way this is good info!
