hi,

I'm trying to change my rear brake pad since it almost gone. After I took off the brake pad. I found out there have no way I can use the c-clamp to reset the Rear Brake Caliper. Is there have any special tool to reset the caliper on S2000.

Thanks
Terry

 

A screwdriver lengthwise in the grove and turn it clockwise. Atleast I think it is clockwise, I usually just do it and now I can't remember which way

 

You need one of these:



Its PITA but it works.

 

there like 8-10 bucks at your local parts store. and they are just as big a pita to use as the screwdriver trick until you get the hang of it. good luck.

 

once you get it moving it goes pretty well.

 

yeah I used the little cube device, I also read on one post that you can use a 1/4 inch ratchet extension right in the center cross area of the piston face. You turn the pistion clockwise to screw it back into the caliper, giving a bit of inward pressure while turning helpsa and I put a bit of lube on the outside circumference before I begin turning.

 

thanks for all you guys help~!!

 

I use the square end of a socket wrench. I want to say 3/4 drive, but it could be 1/2 drive.

 

It's a 3/8 drive extension. Easier if you can grind the rounded edges flat, less likely to slip.

 

Either a 3/8" drive (w/ a 3" extension helps but is not required) in the center intersection of the grooves, or a larger flat-head screwdriver in one of the grooves a bit off-center. Turn it clockwise (righty-tighty) to push the piston in. It takes somewhere around 20 lb-ft to start it turning (a guess, I never measured it), but it's easy to do. If it doesn't turn, it's seized and you're likely a candidate for a rear caliper rebuild. It's actually faster then using the C-clamp on the front, less fumbling around.
