Solution

1. Preparation

Ensure the vehicle is parked on a flat surface and is secured with wheel chocks.
Gather all necessary tools and parts.

2. Remove the Wheel

Tools Required: Socket set, lug wrench.
Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is still on the ground.
2. Jack up the vehicle and secure it with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect Brake Components

Tools Required: Brake pad gauge, dial indicator.
Sub-steps:
1. Visually inspect the brake pads for uneven wear. Replace if necessary.
2. Use the dial indicator to measure the rotor thickness at various points to check for warping.
3. If rotors are warped or below the minimum thickness, replace them.

4. Replace Brake Pads and Rotors (if necessary)

Tools Required: Torque wrench, brake cleaner.
Sub-steps:
1. Remove the caliper bolts and carefully slide the caliper off the rotor.
2. Remove the old brake pads and install new ones, ensuring proper orientation.
3. If replacing rotors, remove the rotor from the hub and install the new rotor.
4. Clean all components with brake cleaner before reassembly.
5. Reattach the caliper and torque the bolts to manufacturer specifications.

5. Reassemble and Test

Tools Required: Torque wrench.
Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and fully tighten the lug nuts in a crisscross pattern to the specified torque.
3. Start the vehicle and pump the brake pedal to ensure proper feel before driving.
