hey i gotta change the rear pads on my fd but im having issues gerring the piston compressed. everything went smooth i disconnected the ebrake line and flapped up the caliper but i cant figure out how to compress the piston so i can fit it around 2 new pads. ive attempted to bleed some of the fluid while compressing but no luck. does it have something to do with rotating the piston to push it in then rotating it back to put the pad in or what cause ive done brake pads on my truck for soe time now and never ran into this problem.



thanks for any help

 

Never had to do the brakes but I want to say that they are the screw type pistons.......

 

Yea they are prolly the threaded pisotns/calipers, most rear are. I have a kit from snap-on that compresses them perfectly, but that doesn't do you much good, your local parts store should have something you can rent.

 

you have to rotate the pistons clockwise to make them retract... this requires a special tool or a little enginutity. I used a set of needle nose pliers.

 

same thing happened to me. At sears they sell a little boz with prongs on it for screrwing in calapers. It was pretty cheep i cant remember the price.

 

k thanks a lot im gonna go for the needle nose approach and then if that dont work out ill hit sears up.

 

There is a special tool available from Mazda. Makes it a snap. Cost me $15.00. Pliers work but not easy to use.
