i wonder how can you release the pressure of the pistons? what tool do i need?? pls help

on the front - you simply pop the cap off the brake fluid reservoir and slowly squeeze the piston in.

To help squeeze the piston in, it often helps to have a big C clamp. Put the clamp over the piston on one side and the back of the caliper on the other side. Turn the screw and the clamp will slowly push the piston in. You might need a piece of wood to give you a flat surface to push against on the back of the caliper.

Makes sure your brake fluid reservoir is not full, otherwise the extra fluid you squeeze out of the piston may overflow the reservoir.

Make sure the C clamp is a good quality one. Some of the CHinese stuff is crud and the head that you put against the piston may not turn like it should, which would scratch the surface of the piston. This isn't that big a deal but I'd rather not scratch things that control how well I am able to stop.

Good Luck,

Jim,


Are you an Attorney? All of your posts are so wordy and all of the attorneys I know can never give a short response. I love it, and you always give great information. My father-in-law was an attorney and you just remind me of him.

and so you dont crack the piston leave the old break pad on the piston then use the c clamp to press against the old pad. It will also be a bit easier this was because you will push the piston in evenly

Jim,

Not an attorney. I am an engineer by training so I get into details. I also like cars so I enjoy tinkering.

Nah, Jim you don't sound like an attorney at all but rather a thorough type individual. Show me an attorney that knows about cars and you'll be showing me one exceptional guy or gal as the case may be. Oh, agree with you 100% about the "tools" made in China. Tried two -- both junk! No more for me. Lincolnlov

Autozone and Murrays both had rotor toolkits as part of their free loaner program. I just did the brakes this past sat (Rotors and Pads). The rotor tool is basically a clamp like device but with the dual pistons up front it was a little easier to push back and have time to get the caliper in place before it extended to much to fit the new rotors. The rotor tool makes the back MUCH easier since the rears are keyed.

Not to sound silly, but I typically open the bleed valve in my caliper when squeezing the piston in, I dont want to push any dirt that may be in the system back up or into my ABS controller.. i think its a better practice.
