Solution

1. Preparation

Tools Required: Socket set, torque wrench, brake cleaner, jack and jack stands, wheel chocks.
Park the vehicle on a flat surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Loosen the lug nuts of the wheel using a socket set.
Jack up the vehicle and securely place it on jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and support it without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Check the brake pad backing for wear indicators; replace if worn beyond specifications.
5. Apply brake grease to the back of the new pads to reduce noise, then install the new pads.

4. Inspect and Clean Brake Rotors

Sub-steps:
1. Clean the rotor surface using brake cleaner to remove any contaminants.
2. Inspect the rotor for signs of scoring, warping, or excessive wear.
3. If necessary, replace the rotors with new ones, ensuring they are torqued to the manufacturer's specifications.

5. Reassemble and Torque Components

Reinstall the caliper and torque the caliper bolts to the manufacturer's recommended torque specs.
Re-mount the wheel and hand-tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the specified value.
