Calipers are an important part of your brake system. They hold the brake pads that offer the support and cushion your brakes need to operate properly. The calipers are just one component of the brake system, so there are other parts along the way to remove in order to access the calipers.
Locate and remove the cover from the brake fluid reservoir. Siphon off two-thirds of the fluid. Do not siphon with your mouth; instead, use a pump or baster.
Loosen the wheel lug nuts and raise the front of the car on jackstands. Make sure the car is securely on the jackstands before starting any work. Push the piston back into the brake caliper core. This can be done with either a C-clamp or screwdriver, depending on the make and year of vehicle.
Remove the brake hose bolt in order to remove the brake hose. Have a rag handy to catch the fluid spilled. Wrap the open end of the brake hose in plastic wrap to avoid more spilling and contamination. Don't disconnect the brake hose from the caliper if you are only removing the caliper.
Unscrew the two caliper mounting bolts, or slide pins, depending on the make and year of your vehicle. Remove the caliper carefully by taking out the bolts completely and rolling the caliper up and backwards off the mounting stud.
