Of course, you should replace a caliper ASAP if it seizes, but you can temporarily free it by releasing pressure and pushing the piston.

How do you remove a rear brake caliper without damaging them?
With your brakes exposed, remove the bolts holding your brake caliper on. There’s usually only two, and they face away from you. DO NOT remove the bolt holding your brake hose on, because that will leak brake fluid and let air in. When you remove the bolts, the caliper should slide off without much force.
What happens to brake fluid when you press the pedal?
When you press the brake pedal, it forces brake fluid to travel through hoses and tubes, and into the brake caliper. From there, the brake fluid pushes against the brake caliper pistons, forcing them to extend out and push against the backs of your brake pads, which pinch the brake rotors and slow you down.

What causes brake calipers to not release?
The most common causes of your brakes not releasing is a seized caliper or brake pad. This typically occurs due to rusting or ageing. Typically, you will notice your vehicle pulling to one side when you press down on your brakes.
How do you get air out of your brakes without bleeding?
Start your car's engine and press on each brake pedal 20 times to push any excess air out of the system (it will take less effort than before because there is no more air in the lines).
Why can't I compress my brake caliper?
When the caliper piston won't compress, it's likely due to a rusty or corroded caliper piston, caused by a bad piston boot. If it's the rear caliper piston, consider the chance that the incorrect wind back procedure is being used.
Why is my caliper piston stuck?
There are several reasons why brakes drag or bind, but it is typically because something in the system has seized, or become stuck. The piston can stick within the caliper. Brakes pads can get skewed and seize. On single-piston calipers, sometimes the slide pins seize.
How does a brake caliper release?
Hydraulic pressure generated by the driver's foot pressing on the brake pedal goes from the master cylinder to each brake caliper. Fluid pressure inside the caliper pushes one or more pistons outward to apply the brake. When the brake pedal is released, hydraulic pressure drops and the calipers loosen their grip.
How do you release seized brakes?
To do this safely, turn on your vehicle and drive forward and reverse in succession. You may find that your vehicle feels like the brakes are on and will not budge in either direction but persist with the motion and this should release the brakes.

How do we check it?
The process is simple: the first thing to do is to remove any proportioning that may be present in the system. If you have an adjustable proportioning valve, it should be adjusted so that the line sees full pressure (generally fully clockwise). If you have a factory proportioning valve, you should remove it and re-plumb with an adjustable one.
What is the target?
For TBM brakes, under these circumstances, we recommend a brake line pressure of 950 -1000 psi. This gives us a system that is easy to modulate for normal braking, is comfortable to drive, and still allows some headroom for panic stops, which could cause line pressure to spike upwards of 1400-1500 psi.
What if my results don't match the target?
Numbers outside the normal range should be addressed, and can be, in a variety of ways. If you need to make a change to bring the numbers within recommendations, give us a call or post up your question, we are happy to help!
