How To Remove Rear Brake Pads on 1995 Integra

I'm planning to do a complete 4 wheel brake job on my '95 Acura Integra this weekend. the front pad removal is very straightforward, but I simply cannot figure how to remove the rear or more specifically- how to back-off the caliper so I can put new pads on them. Any special technique or tool needed for this job or am I really blind? Thanks for any input! Jay

See how the piston has a cross deeply milled into it? You use that to screw the piston back in again (clockwise for both sides).

Unfortunately, the caliper is too small to allow use of the standard "cube" tool you can buy at most part places. The solution? Buy a great big flat-blade screwdriver, the biggest you can find. The one I have is 15" long.

Use a grinder to undercut the sides of the tip, so you end up with sort of "hooks" at the end. Like so: ONLY grind off enough to make the undercut. Do NOT reduce the size of the tip.

These hooks dig into the sides of the cross, preventing the screwdriver tip from slipping out and gouging the surface of the piston as you turn it. As the caliper ages, considerable force can be required to turn the piston back in on account of gum buildup between the internal screw and its receiving threads in the piston.

So you might find the piston to be /extremely/ difficult to turn. But maybe you'll get lucky and it will be fairly easy. Either way, screw it right in until it's flush with the surface of the caliper. It's not possible to screw it too far in, so don't worry about that. What you do need to watch for is that the dust boot doesn't start binding and wrinkling as you seat the piston.

Rear disc brakes are a dumb idea for road cars. Incorporating the parking brake into the caliper is even dumber. But that's what we have, so we live with it.

Oh, and one more thing: Make sure the cross is turned so it will mate with the pin on your new inner pad. The pad's pin, in other words, needs to slide into the channel of the cross when the caliper is pushed home again.

I have lots more info pertaining to your Honda brakes, so if you encounter trouble, post back here again.
