Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, torque wrench, brake pad gauge, OBD-II scanner.
Safely lift the vehicle using a jack and support it with jack stands. Ensure the vehicle is on a level surface.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts with a lug wrench before lifting the vehicle.
2. Remove the lug nuts and take off the wheel to access the brake components.

3. Inspect Brake Components

Sub-steps:
1. Check brake pads for wear using a brake pad gauge; replace if they are worn below the manufacturer’s specification.
2. Inspect the rotors for any grooves, scoring, or warping. If damaged, consider resurfacing or replacing them.
3. Ensure calipers move freely and are not sticking. Clean and lubricate caliper guide pins if necessary.

4. Replace Brake Pads (If Necessary)

Sub-steps:
1. Remove the caliper bolts using the appropriate socket size and carefully lift the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Install new brake pads in the caliper bracket, ensuring they are seated properly.
4. Compress the caliper piston using a brake tool to accommodate the new pads.
5. Reinstall the caliper over the new pads and secure it with bolts, tightening to manufacturer torque specifications.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications in a criss-cross pattern.
3. Pump the brake pedal a few times to ensure proper brake engagement.
4. Test drive the vehicle at low speeds to listen for any remaining noise and verify brake functionality.
