Clean and lubricate the slider pins. Use a wire brush to remove any corrosion from the pins, then apply a small amount of high-temperature brake grease to them. This will help the pins move smoothly and prevent them from corroding in the future.
Check the brake caliper for damage. Look for cracks, chips, or other damage to the caliper. If the caliper is damaged, it will need to be replaced before you can proceed.
Check the brake pads for wear. If the brake pads are worn, they will prevent the piston from retracting properly. You should ensure the brake pads are replaced if necessary.
Press the piston back into the caliper using a C-clamp or brake piston tool. This will compress the brake pads and allow the piston to fully retract.
Reinstall the brake caliper over the rotor. Tighten the caliper bolts in a star pattern, gradually tightening each bolt a little bit at a time until they are snug.
Test the brakes to ensure they are working properly. Pump the brake pedal a few times until the brakes feel firm. Go for a test drive and ensure the brakes are working properly before you drive your vehicle.
