Thankfully often a simple c-clamp will get you going. Another way to remove the caliper piston is to use the brake system’s hydraulic pressure. Just remove the caliper from the disc and pump the brake pedal to move the piston past the corroded area. After this step it’s easier to disassemble and rebuild.
Q. What size are brake caliper bolts?
The caliper bracket bolts are 18 mm. Be prepared to put some serious torque on the bolts to remove them.

Q. What tool can be used to free a seized caliper piston?
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.
Q. Is a seized brake caliper dangerous?
If you have a stuck caliper, the brake pad will not completely disengage from the surface of the brake rotor. This means you will be driving with the brakes applied slightly all of the time. Driving with a stuck caliper can create stress on the transmission, causing it to fail earlier.
Q. What causes a caliper to seize?
The main cause of brakes seizing is inactivity. If a vehicle is sitting for a long period of time, especially out in the open, it’s not uncommon for the brakes to seize. This is usually a case of the pads becoming ‘stuck’ to the disc as it becomes coated in surface rust, particularly after rain.
Q. What causes both front calipers to stick?
You may find that the rubber boot surrounding the caliper piston is torn, exposing it to rust and debris, which can cause the caliper to stick. The solution here is to replace the brake caliper assembly. Alternatively, if a brake hose has worn out, it can also cause the caliper to stick.
Q. Can I drive with a sticking caliper?
Driving with a stuck caliper will quickly wear and damage the brakes. Driving with severely worn or damaged brakes is not safe. Stuck closed and the brake will overheat. It’s likely to start a fire and cause major damage.
Q. Can ABS cause caliper to stick?
ABS will only effect a wheel locking up during very hard emergency braking or in slick road conditions if its a constant drag at all times you need to check your caliper. No it can not make a brake caliper stick.
Q. Can a bad ABS module cause spongy brakes?
When your ABS system malfunctions is can also cause spongy brake pedal. By measuring the wheel speed of each wheel when you are in a panic stop situation the ABS computer controls the brakes to keep the tires from locking up. Your ABS does this by releasing brake pressure o that wheel.
