Why do brakes not release after being applied?
I am referring to rim brakes; the types of hand brakes where there is a separate lever for front and rear and when you squeeze them little pads touch to the rim to stop the bike. How can I adjust the brakes in such a way that they apply pressure to the rim but also release when the lever is released?
What should I do if my bike brakes won’t release?
Many linear pull or V-brake calipers have return spring adjustment screws near the pivot. You could try increasing the return force and see if that sufficiently opens the calipers. Disconnect the cable from the calipers. With the cable removed do the calipers move freely?
Can a caliper not release cause brake drag?
Just like with the master cylinder not releasing causing the brake drag, a caliper not releasing and staying applied can do the same thing. If only one position is dragging, this could be the case.
Why does my car pull to the side when I release the brake?
Brake drag is caused by the brake pads or shoes not releasing completely when the brake pedal is released. If it involves only one of the front brake units, the vehicle will pull to the side with the dragging unit. Dragging brakes must be repaired immediately because it will result in overheated parts and possible damage to the braking system.
What to do when your front brakes won’t release?
Spray a little penetrating oil onto the cleaned piston, use the C-clamp to push the piston back into the caliper. Place the brake pads back into the caliper in the same position as they were removed. Reinstall the caliper and pads onto the spindle. Push the brake pedal while someone watches the caliper extend out against the brake pads.
Why are my rear disc brakes not releasing?
The heavy caliper dust and heat indicates “pad drag” from being seized up. You may have to replace the rotor as well as the calipers and pads. I had a similar issue with my rear disc brakes. After replacing both rear caliper’s, braking improved very noticeably. Good luck with your project. Eric was talking about this a few weeks ago…

Why are my brakes not opening after applying?
Brake calipers have return springs to move open the caliper arms after closing force supplied by the force on the brake cable from the levers is removed. If the calipers are not opening there are several things that can cause this: Return springs are too weak Caliper pivots stiff or jammed
What to do if your rear brake caliper won’t go in?
The rear calipers usually integrate the parking brake by fitting a brake lever and cable to the caliper. The manual parking brake obviously needs to be released before the removal procedure. Use a wind-back tool to turn and push the piston simultaneously. Some calipers will turn clockwise and some anti-clockwise.
Is there a way to rerelease the parking brake?
The best way to do this is to use the diagnostic tool or parking brake tool to do. However, in many cars, it will work to engage the parking brake with the button. You will hear the parking brake motors sound for 2-3 seconds until the parking brake is engaged. When it is engaged, you can rerelease it.

What happens when you change rear brake pads?
The aluminum housing corrodes internally and when you press the piston back in it will stick almost everytime. Replacing the brake fluid yearly helps this problem but it does not guarantee it won’t happen again next time you change pads.
