Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.
Safely lift the vehicle using a jack and secure it with jack stands.
Remove the wheel using a lug wrench.

2. Inspect Calipers

Remove the caliper bolts with a socket.
Carefully slide the caliper off the rotor without disconnecting the brake line.
Check for any signs of sticking or improper movement of the caliper. Clean the caliper slides using brake cleaner if necessary.

3. Replace or Adjust Components

If the caliper is sticking, consider replacing it or lubricating the slides with high-temperature brake grease.
Inspect the brake pads. If they are worn unevenly, replace them with new pads.
Ensure that the brake pads are properly seated in the caliper bracket.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for any signs of warping or scoring. If the surface is damaged, replace the rotors.
If replacing, follow the manufacturer's specifications for rotor installation and torque settings.

5. Reassemble and Torque

Reinstall the caliper over the new pads and rotor, ensuring it slides freely.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and torque the lug nuts to the recommended values.

6. Test and Adjust Brake System

Before lowering the vehicle, pump the brake pedal to ensure proper pad seating.
Check the brake fluid level and top off if necessary.
Lower the vehicle safely and perform a test brake to ensure proper function.
