Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Remove Wheel

Tools Required: Lug wrench
Sub-steps:
1. Loosen the lug nuts on the wheel slightly before lifting the vehicle.
2. Use a jack to lift the vehicle and secure with jack stands.
3. Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench
Sub-steps:
1. Remove the caliper bolts using the socket set.
2. Carefully slide the caliper off the rotor and hang it using a bungee cord to prevent stress on the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Inspect the caliper for any signs of sticking; replace if necessary.
5. Install new brake pads ensuring they are seated properly in the caliper bracket.

4. Check and Resurface/Replace Rotors

Tools Required: Brake rotor gauge, resurfacing machine (or replacement rotors)
Sub-steps:
1. Check the rotor thickness using a brake rotor gauge.
2. If the rotor is within allowed thickness, consider resurfacing if warped.
3. If replacement is needed, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
4. Install the new or resurfaced rotor onto the hub.

5. Reassemble Brake Components

Tools Required: Torque wrench
Sub-steps:
1. Reinstall the caliper over the new pads and rotor.
2. Secure the caliper bolts and torque to specified manufacturer values (usually around 25-35 ft-lbs).
3. Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Tools Required: None
Sub-steps:
1. Lower the vehicle from the jack stands.
2. Tighten the lug nuts to the specified torque value (typically 75-85 ft-lbs).
3. Reconnect the battery.
