Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and secure it with wheel chocks.
Jack the vehicle up and support it with jack stands.
Disconnect the battery to avoid any electrical issues.

2. Remove the Wheel

Using a lug wrench, remove the lug nuts and take off the rear wheel to access the brake caliper.

3. Remove the Brake Caliper

Tools Required: Socket set
Loosen and remove the caliper mounting bolts using a socket.
Carefully slide the caliper off the brake rotor.
Support the caliper with a bungee cord or wire to avoid stressing the brake line.

4. Inspect and Replace Components

Inspect the caliper for any visible damage or corrosion.
If the caliper is leaking or damaged, consider replacing it with a new or remanufactured unit.
Replace the brake pads if they are worn unevenly or below the manufacturer's specifications.
Check and replace the caliper slide pins if they are seized or corroded.

5. Reinstall the Caliper

Position the new or repaired caliper back onto the rotor.
Reinstall and torque the caliper mounting bolts to the manufacturer's specifications (typically around 25-30 ft-lbs).
Ensure that the brake pads are correctly positioned within the caliper.

6. Refill and Bleed the Brake System

Reconnect the brake line to the caliper and tighten it securely.
Refill the master cylinder with brake fluid to the required level.
Bleed the brake system to remove any air trapped in the lines, starting from the furthest caliper to the nearest.

7. Reinstall the Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle off the jack stands and onto the ground.
Torque the lug nuts to the manufacturer's specification (usually around 100-110 ft-lbs).
