Why does my caliper piston not go back in?
It could still have pressure in the lines that may be causing you problems. it might be seized. and for the rear ones you dont want to push them back in straight. you want to go rent a tool and it pushes it in and turns it at the same time. good luck with the install. press down and screw that piston clockwise…. i tried the c-clamp.
Why are my Pistons not pushing back in?
It turns out to be a common fault, where the original pads are a mm or so thinner than new ones, and the fluid in the reservoir was put in to suit the thinner pads, so, the pistons could not be pushed all the way back in, not matter what I did to them.
Do you need to screw the piston back in?
you need to screw the piston back in it will not PUSH straight back in. There is a tool specificaly for this but a large screw driver (FLAT) will work well too.
What to do about rear brake caliper piston issue?
Recently I did the rear brake pads in my 2015 Ford Explorer. The passenger side was a breeze, spin the piston and it retracted no problem. Went to drivers side and must had made 100 turns and it just wouldn’t retract. What I did was take my old C clamp and applied pressure on the piston as I spun it.
Why does one brake piston stick harder than the other?
It’s really not odd that one sticks more than another. Sometimes you will have one move freely and the other be frozen, stuck hard, and needing a rebuild. It just depends on tolerances, heat, and water impurities of the fluid.

Do you need to bleed the brake piston?
Pistons don’t just “screw in” they need to be compressed as well and doing both can be tricky. Some DO release pressure at the bleeder screw, if you end up getting air in then yes you’d end up needing to bleed the brake there.
How do you remove a non retracting piston?
Squeeze the lever, the non-retracting piston should be fully out. While holding the lever wipe around the piston with a clean lint free cloth. Release the lever and repeat lubricating 5 more times, the piston should now be retracting.
Why is my disk brake not fully retracting?
My front disk brake’s piston doesn’t fully retract. While I can ride the bike, the brake is slightly rubbing. (IE, if I just spin the wheel with my hand, it’ll go around about one and a half times and then stop.) It’s definitely slowing me down. If this fixable? The advice I got was that it’s not worth the trouble and to buy a replacement set.
Why are the brakes on my Juicy 7 not retracting?
The current brakes are Avid Juicy 7s that are about 7 years old I would try repairing them before binning them and purchasing the Shimano upgrade. If there is no obvious fluid leak around the piston the seals are likely in good order and you’ve got a sticky piston rather than a failed calliper. This is a simple fix: Remove wheel and brake pads.
