View Full Version : Caliper Piston Tool Question [Edit: w/another added]

06-25-2009, 12:57 PM
I am replacing my brakes and rotors, and ran into a complication. This is the first time for me installing them, so bear with me. I finished the fronts successfully and the rears are giving me issues. I used the piston tool to compress the piston, but how do I get it off? Did I maybe compress it too much. I tried to unscrew it, but that is not happening. Either I am not placing enough force, or it is not designed to do that. Either way, how do I get the tool off the rear caliper after having the piston compressed? Thanks!

P.S. Or maybe I'm just an idiot. If that is the case, help would still be appreciated[cool]

New Question: As per post #4, how do I properly break in new pads and rotors? Thanks!

Nvmd. Called up my mechanic and he told me how to get it off [wrench]

do you have any pics Seerlah? I did mine and did not have an issue in the rear...

Pics might be able to help us help you:)

I was able to get it off. Thanks though. I did not know you had to use an adjustable wrench on the middle section that spirals on the threaded rod to release it. Anyways, job completed and now I need to place th tires back on. The conical bolts are f*cking annoying. Now I know why people switch over to the wheel stud kit.

New Quesion: How do you properly break in new pads and rotors. Do I do a couple 35mph moderate stops accompanied by 2-3 45mph hard stops? Thanks!

Look on Hawk pads website they tell you how. I have gotten my stock rotors so hot that they now have a blue ish tint tho them.

I took this off their website:

-After installing new brake pads, make 6 to 10 stops from approximately 30-35 mph applying moderate pressure.
-Make an additional 2 to 3 hard stops from approximately 40 to 45 mph.
-Allow 15 minutes for brake system to cool down.

What do they mean by 'DO NOT DRAG BRAKES'?

means do not hold foot on the brake pedal which causes the pads to drag on the rotors..

Thanks. One more question though. I have Motul 5.1 fluid as I am also planning on doing a brake fluid flush (need/want to order Motive bleeder first). While compressing the piston, the brake fluid had risen and I placed it in an extractor. After I depress the brake pedal again, it is supposed to lower back down. Should I mix some of the Motul fluid I have or place the old fluid back, to get it back to level? Also, should I leave the cap off the resevoir when I depress the pedal?

Bump. Pardon the annoying bump, but trying to get this done[drive]

I actually used that write up with the link attached to install my pads and rotors. Will be using the same DIY to bleed my system[up]. It's ok though. The fluid is right at the fill max line, so no worries. I was just surprised when I took my car off the jacks; learn something new everytime[:p]. Brakes feel firm, e-brake at proper level and about to go and break in the new brakes[drive]
