brake pad replacement, can't push piston back
i tried to replace the original oem brake pads on my 96 vtec sol last night. everything went fine until it came time to put the brake assembly back together.
i didn't loosen the master cylinder cap, although i opened up the bleed valve on the rear brake i was working on, to push the piston back in. i pushed, clamped, leveraged and did what i could to push that damn piston back so i could fit it over the new brake pads but it wouldn't budge.
since this is the first time for me i'm at a loss here, what can i do to make the piston go back in? i read you can screw it back in?

Re: brake pad replacement, can't push piston back (EKchump)
Try rotating the piston a little bit with vice grips. I had the same problem on my EX fronts. I even bent a heavy duty C-Clamp thats how much it wouldn't budge. I just rotated the piston a little bit and then it compressed quite easily. I have no clue what would make it do that but that is how I fixed it. Hope that helps. BE CAREFUL NOT TO PULL THE PISTON OUT WHEN YOU ARE ROTATING THOUGH!

Re: brake pad replacement, can't push piston back
For the rear pistons, you have to screw them back in, they make a special tool or you can use a pair of needle nose pliers. Just stick each tip of the pliers into 2 of the groves and spin it clockwise(right). Let me know if that helps any.

Sounds to me like perhaps your caliper is frozen. You may just have to go buy a rebuilt caliper.

its not just hondas all rear disc brakes need to be rotated back in i don't recall which direction but like some previous posts said you can use pliers or the special tool from honda, (or any will do).

Re: (stock00)
As far as I know you can't push it back with a clamp. If it's the same as my 93 civic si, then there is a "+" groove pattern on your piston. Use nose pliers to turn it clockwise.
If it's too tough go to autozone or auto part store and get a special "cube" socket for brake piston. It's cube shape has teeth that will go into those grooves and you turn it with 3/8" drive rachet. It will give you more torque than the nose pliers.
