Solution

1. Preparation

Tools Required: Jack and jack stands, wheel chocks, lug wrench, brake cleaner, container for brake fluid, safety glasses, gloves.
Elevate the vehicle using a jack and secure it with jack stands. Remove the wheel using the lug wrench and set it aside.

2. Inspect and Clean

Inspect calipers for any signs of damage or rust.
Clean the calipers with brake cleaner to remove dirt and debris.

3. Remove Caliper

Tools Required: Socket set, torque wrench.
Remove the bolts securing the caliper to the bracket using the socket set.
Carefully slide the caliper off the rotor and suspend it using a bungee cord to avoid straining the brake line.

4. Replace Caliper (if necessary)

Tools Required: Brake fluid, new caliper, new brake pads (if worn), bleeder wrench.
Remove the old caliper and install the new caliper onto the bracket.
Connect the brake line and ensure it is tightened according to specifications.
Replace brake pads if necessary, ensuring they are seated correctly.

5. Bleed Brake System

Use a bleeder wrench to open the caliper bleed screw.
Have a helper press the brake pedal to push fluid through the system until no air bubbles are visible.
Close the bleed screw and repeat the process until the pedal feels firm.

6. Reassemble

Reinstall the wheel and lower the vehicle.
Torque lug nuts to the manufacturer’s specifications.
