What to do when your brake caliper is stuck?
For seized caliper pistons, or slide pins, a special tool is available to apply force and retract the pad. Often a simple C-clamp can be used. To remove a caliper piston that has become seized, the hydraulic pressure of the brake system itself can be used.
What happens when a piston is stuck in the caliper?
If the piston is stuck within the caliper, or the pad is stuck, the car can feel down on power (as if the parking brake is on). You may also notice the car pulling to one side with the steering wheel pointed straight, when cruising and not applying the brake. As you drive,…
What causes the brake pads to seize on a single piston car?
On single-piston calipers, sometimes the slide pins seize. Finally, if a car is allowed to sit in a damp environment, the pads can actually become stuck to the disc. If a brake becomes seized when the vehicle is unused, the symptoms are fairly obvious – when you try to drive it feels like the brakes are on!
Why are my rear brakes not working properly?
Brakes are subjected to a huge range of temperatures, are permanently exposed to the elements, and are rarely serviced or inspected between pad changes. As a result, corrosion can build up in key areas and cause failure. In the case of the rear brakes binding, it may not be the caliper/cylinder.
What does a brake caliper do for a Jeep Grand Cherokee?
Your brake caliper for Jeep Grand Cherokee is a vital piece to your SUV’s brake system.

How to troubleshot a sticking caliper on a Jeep Wrangler?
How I troubleshot it: Jacked the affected wheel up. Took the tire off. Pumped the brakes until the rotor would not turn. I unscrewed the bleed screw. Rotor turned so it was the hose. If the rotor had not turned it would have been the caliper. Trouble shooting is the key. Don’t just go replacing parts.
Can a brake caliper be changed on one side?
Changing the pads on one side will not make them wear quicker. If they are dragging, then its not a problem with the pads, but with the caliper. When releasing the brake, the pistons (on one side of the caliper only)return a bit and the caliper will slide over the caliper sliding pins, and will release the other side pads.
What causes the brake to stick on a Jeep Wrangler?
Its also pretty common that the rubber hose deteriorates on the inside. This allows the fluid to go through one way when you push on the pedal and since there is no pressure pushing back, it gets trapped and won’t release the brake. It slowly releases the pressure and the brake frees up.
