Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the battery to avoid any electrical issues.

2. Remove Wheel

Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Remove Caliper

Use a socket set to remove the caliper mounting bolts.
Carefully slide the caliper off the rotor, ensuring not to damage the brake line.
Support the caliper with a bungee cord to avoid straining the brake line.

4. Inspect and Clean

Check the caliper slides and pins for dirt and corrosion.
Clean the caliper slides and pins using brake cleaner and a wire brush.
Lubricate the pins with high-temperature brake grease.

5. Replace or Repair Components

If the caliper is damaged or excessively corroded, replace it with a new unit.
Inspect brake pads and replace them if they show uneven wear.
Check the brake line for any damage and replace if necessary.

6. Reassemble Components

Reattach the caliper over the rotor and secure it with the mounting bolts. Torque to manufacturer specifications (typically around 25-35 ft-lbs).
Reinstall the wheel and hand-tighten the lug nuts.

7. Final Steps

Lower the vehicle and remove the jack stands.
Tighten the lug nuts to the specified torque (typically around 80-100 ft-lbs).
Reconnect the battery and check fluid levels in the brake master cylinder.
