I could not push back the piston with a small vise is there a better way to do it or i'm i missing something, thank you for any help.

 

don't push any harder with the vice, it will blow the pistons in the caliper. when the brakes are mounted up, on theback of the caliper, there is a 14mm bolt and when you pull that bolt, there is an allen headed screw under it. back that allen screw out all the way and it will release the caliper.

 

by back of the of the caliper i mean the part that is the inner most part of the wheel well.

 

Yes, you are correct. You cannot simply compress the piston as w/earlier calipers on earlier disk brakes.
There is a tool that inserts into the detents in the face of thepiston and allows it to be screwed in... clockwise, if memeory serves. I also understand that in a pinch a pair of needle nosed plier may do the trick as well. I'm sure the factory would not approve of this last method, and I myself have never tried it either.

 

tomorrow with better like i'll try to find the bolt and see what happens .
Thanks a lot for the excellent reply and very promt aswell.

 

Fail to change the pads, there is not 14mm bolt on this brakes and i try a set of tools to turn the piston clock wise and no luck, thanks for the help will have to spend some money.

 

Ah Man. Sorry about that. I know the pistons have to be screwed in though.Rear calipers, and some fronts I guess, have been that way for about 10-12 years now. Oneguy on the MS3 thread (can't remember who now) did it.
I've never taken one of these calipers apart so I can't explain why they work this way, but I would be curious to know.

 

 

ignore the red ring. just look at the black bolt that is staring you in the face. you should be able to back out that bolt and there will be a rubber seal on that bolt. inside of that bolt, there is an allen headed screw that backs out to loosen the caliper. you won't be able really to see the screw, but if you put in an allen wrench, you can feel it. when the brakes are mounted, this is the inside of the wheel well.

 

you may need to pull the e brake connects first
