1. Gather the necessary tools: a C-clamp, a set of wrenches, and a large flat-head screwdriver.
2. Park the vehicle in a safe location, apply the parking brake, and chock the wheels.
3. Locate the brake caliper on the wheel that you need to compress. The caliper is the metal housing that contains the brake pads.
4. Use the C-clamp to compress the caliper piston back into the caliper. Place the C-clamp on the outer edge of the brake pad and tighten it until the piston is fully compressed.
5. Use the large flat-head screwdriver to hold the caliper piston in place while you remove the C-clamp.
6. Use the wrenches to loosen and remove the two bolts that hold the caliper in place.
7. Remove the caliper from the vehicle.
8. Use a brake cleaner to clean the caliper piston and the inside of the caliper.
9. Reinstall the caliper onto the vehicle and tighten the bolts.
10. Test the brakes to ensure that they are working properly.
It is important to note that compressing the brake caliper is a delicate procedure that should be done carefully. If the caliper is not properly compressed, it could damage the brake system and cause a loss of braking power. If you are not comfortable performing this procedure, it is best to take your vehicle to a qualified mechanic.
