Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Wear safety gloves and glasses for protection.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts on the wheel using a socket set.
2. Lift the vehicle with a jack and secure it with jack stands.
3. Remove the lug nuts completely and take off the wheel.
Tools Required: Socket set, jack, jack stands.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set, and gently slide the caliper off the rotor.
2. Inspect the brake pads for thickness; replace if worn down to 3mm or less.
3. If replacing, remove the old pads and install new pads, ensuring they are seated properly.
Tools Required: Socket set, brake pad spreader.

4. Inspect and Resurface or Replace Brake Rotors

Sub-steps:
1. Check the rotor for grooves or warping; if damaged, either resurface or replace.
2. If resurfacing, follow the manufacturer's specifications for rotor thickness.
3. If replacing, remove the rotor by unscrewing the retaining screws and sliding it off the hub.
4. Install new rotor and tighten screws to manufacturer specifications.
Tools Required: Impact wrench (if necessary), torque wrench.

5. Reassemble Braking System

Sub-steps:
1. Reinstall the caliper over the new pads and rotor.
2. Tighten caliper bolts to the specified torque.
3. Reinstall the wheel and hand-tighten the lug nuts.
Tools Required: Torque wrench, socket set.

6. Lower Vehicle and Finalize

Sub-steps:
1. Lower the vehicle off the jack stands.
2. Tighten the lug nuts in a crisscross pattern to the specified torque.
3. Pump the brake pedal a few times to ensure proper seating of the new pads.
Tools Required: Torque wrench, jack.
