Solution

1. Preparation

Gather necessary tools and parts before beginning the repair.
Tools Required: Jack and jack stands, lug wrench, brake cleaner, socket set, torque wrench, multimeter (if needed).
Parts Required: New brake caliper (if replacement is necessary), brake pads (if uneven wear is noted), brake fluid.

2. Lift the Vehicle

Use the jack to lift the vehicle and ensure it is securely placed on jack stands.
Remove the wheel using the lug wrench, exposing the brake caliper and rotor.

3. Inspect and Clean the Caliper

Check the caliper guide pins for corrosion and ensure they move freely.
Clean the caliper surface and the guide pin area with brake cleaner to remove dirt and debris.

4. Test Caliper Movement

Using a C-clamp or brake caliper tool, carefully compress the caliper piston. Ensure it retracts smoothly without excessive force.
If the piston does not retract smoothly, the caliper may need to be replaced.

5. Reassemble and Torque

Reinstall the caliper onto the bracket and secure it with the appropriate bolts.
Use a torque wrench to tighten the caliper bolts to the manufacturer’s specifications.
Reattach the wheel and lower the vehicle.

6. Brake Fluid Check

After reassembly, check the brake fluid level and top up if necessary.
Bleed the brake lines if any air is introduced into the system during caliper servicing.
