Compress rear caliper piston ??

[Aceshigh]

Guys, Probably been discussed 100's of times, but I did 6 searches and rear 20 threads, and I couldn't find the answer to my question. So......

2005 Busa.
I got the rear caliper off, but I can't get the pistons to push back in.
Is there a trick to this, or is my caliper seized up ??

go to your local auto parts store and loan a caliper compression tool. if not available, use C-clamps

Probably way obvious, but you wont (easily) compress it with the top on the reservoir... From there, anything that'll give you a little leverage should get things moving...

Open the bleeder, it should compress easily then. You will also lose very little brake fluid. If you remove the master cylinder cap, a small amount of fluid may overflow when you compress the cylinder.

Leave the old pads in place and insert a large flat blade screwdriver between the two pads and twist.

Yep, that's how I do it.

you've got to give some displacement for the fluid to go somewhere. Either crack the bleed or take the resevoir cap off. Either way watch for fluid overflow.

^ What they said .
Just be careful no to allow any brake fluid to get on any painted surfaces . If it does wipe it up immediately .

This worked. I already had the MC open.

I'm a f''n retard. I've done brakes probably 20x and for some strange reason I thought the
INNER solid cup ring was the piston and it wasn't budging. Doh!!!!

I'm good now, and I'm going to go lick a window.

Okay, I'm not good.

Quick question. Does the rear caliper have 2 pistons ??
One on the inside of the rotor, and one on the outside ???
I can't really tell because my inner one isn't budging, and I can't see a seal around it.

I can't seem to fit the pads in WITH the rotor.
The pads I bought are the Sintered pads off that guy on Ebay I found in another thread.
I've got the outer piston all the way in, MC open, and I got the pads in no problem, but no room for the rotor.

Someone posted a rear caliper diagram in a thread I found before, but now I can't find the damn thing.

Disregard.....I can't delete the post.

It's a 2 piston caliper, so I have to rebuild it.
