Solution

1. Preparation

Gather tools: socket set, torque wrench, brake cleaner, caliper tool, and safety gloves.
Lift the vehicle using a jack and secure it with jack stands.
Remove the wheel to access the brake assembly.

2. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using the socket set and carefully slide the caliper off the rotor.
2. Remove the old brake pads from the caliper bracket.
3. Measure the thickness of the old pads; replace if below the manufacturer's minimum specification.
4. Clean the caliper bracket and rotor with brake cleaner to remove dust and debris.
5. Install new brake pads, ensuring they are positioned correctly in the caliper bracket.

3. Inspect and Replace Caliper (if necessary)

Sub-steps:
1. Check the caliper for signs of damage or binding. If it appears faulty, replace it.
2. Remove the caliper from the bracket by unscrewing the mounting bolts.
3. Install the new caliper and torque the bolts to the manufacturer’s specifications (usually around 25-30 ft-lbs).
4. Reconnect the brake line if disconnected and ensure there are no leaks.

4. Check and Resurface/Replace Rotors (if necessary)

Sub-steps:
1. Inspect the rotor surface for warping or grooves. Use a dial indicator to measure runout.
2. If the rotor is warped, either resurface it (if within specifications) or replace it.
3. Reinstall the rotor and torque the wheel lug nuts to the manufacturer's specifications (typically around 76-83 ft-lbs).

5. Reassemble and Finalize

Sub-steps:
1. Reinstall the caliper over the new brake pads.
2. Torque the caliper bolts to the specified torque.
3. Reinstall the wheel and lower the vehicle to the ground.
4. Pump the brake pedal several times to seat the new pads.
