Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface.
Secure the vehicle with wheel chocks and jack stands.
Disconnect the battery to prevent accidental activation of electronic components.

2. Remove Wheel

Use a lug wrench to loosen and remove the wheel nuts.
Carefully remove the wheel to expose the brake assembly.

3. Inspect and Clean Caliper

Check for signs of rust or debris on the caliper and bracket.
Use brake cleaner to remove dirt and grime from the caliper.
Inspect the caliper mounting points for proper alignment.

4. Caliper Removal

Remove the caliper mounting bolts using the appropriate socket.
Carefully slide the caliper off the bracket, ensuring not to damage the brake line.
Hang the caliper using a bungee cord to avoid strain on the brake line.

5. Inspect and Replace Components

Check the caliper piston for smooth operation; if stuck, it may need replacing.
Inspect the rubber caliper seals for wear or damage; replace if necessary.
If the brake pads are worn unevenly, replace them with a new set.

6. Reassemble Caliper

Apply a thin layer of brake grease on the caliper slide pins.
Reinstall the caliper over the brake pads and bracket.
Tighten the caliper mounting bolts to the manufacturer's specified torque (typically 20-25 ft-lbs).

7. Reinstall Wheel and Test

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer’s specifications (typically 100-120 ft-lbs).
Reconnect the battery and perform a test drive to assess braking performance.
