Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Wear safety gloves and goggles.

2. Remove Wheel

Sub-steps:
1. Loosen lug nuts slightly while the vehicle is on the ground.
2. Raise the vehicle using a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Jack, jack stands, lug wrench

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket wrench.
2. Carefully lift the caliper off the rotor and support it with a bungee cord to avoid straining the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Compare the thickness of the new pads to the old pads. Install new pads if worn below specifications (usually 3 mm or less).
5. Apply brake grease to the backing of the new pads to prevent squeaking.
Tools Required: Socket set, brake pad spreader or C-clamp, bungee cord

4. Inspect and Replace Brake Rotors (if necessary)

Sub-steps:
1. Check the rotor surface for scoring or grooves.
2. If damaged, remove the rotor by unbolting it from the hub.
3. Install new rotors, ensuring they are clean and free of oil.
4. Torque rotor bolts to manufacturer specifications (usually around 80-100 ft-lbs).
Tools Required: Torque wrench, socket set

5. Reassemble and Test

Sub-steps:
1. Reinstall the caliper over the new pads.
2. Bolt the caliper back into place and ensure proper torque.
3. Reattach the wheel and hand-tighten the lug nuts.
4. Lower the vehicle and then torque the lug nuts to manufacturer specifications (usually 80-100 ft-lbs).
5. Pump the brake pedal a few times to seat new pads.
Tools Required: Torque wrench, lug wrench
