Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, dial indicator, torque wrench, brake cleaner
Safely lift the vehicle and secure it on jack stands.
Remove the wheels using the lug wrench.

2. Inspect and Replace Brake Rotors

Sub-steps:
1. Remove the brake calipers by loosening the caliper bolts and hanging them using a bungee cord to avoid straining the brake line.
2. Remove the brake pads from the caliper bracket.
3. Use a dial indicator to measure the runout of the rotors; replace if warped (more than 0.002-0.003 inches).
4. If replacing, remove the rotor by unscrewing the retaining screws (if equipped) and sliding it off the hub.
5. Install new rotors, ensuring they are clean and free of oil, and torque retaining screws to manufacturer specifications (approximately 7-11 ft-lbs).

3. Inspect and Replace Brake Pads

Sub-steps:
1. Check the thickness of the brake pads; replace if they are worn to less than 1/8 inch.
2. Clean the caliper bracket and apply brake grease to the contact points.
3. Install new brake pads into the caliper bracket, ensuring they are positioned correctly.

4. Reassemble Components

Sub-steps:
1. Reinstall the brake caliper over the new pads, ensuring it fits snugly.
2. Tighten caliper bolts to manufacturer specifications (typically around 20-25 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and torque the lug nuts to manufacturer specifications (usually 76-83 ft-lbs).
