Solution

1. Preparation

Tools Required: Jack and jack stands, lug wrench, torque wrench, socket set, brake cleaner, wire brush, caliper tool.
Park the vehicle on a flat surface, engage the parking brake, and disconnect the battery.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts with a lug wrench.
2. Use a jack to lift the vehicle and secure it with jack stands.
3. Remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Sub-steps:
1. Remove the caliper bolts using a socket set.
2. Carefully slide the caliper off the rotor and suspend it using a wire hanger (do not let it hang on the brake line).
3. Remove the old brake pads from the caliper bracket.
4. Use a brake cleaner and wire brush to clean the caliper and rotor surface.
5. Install new brake pads ensuring they are seated correctly in the caliper bracket.
6. Compress the caliper piston using a caliper tool to fit the new pads.
7. Reinstall the caliper over the new pads and secure it with caliper bolts, torqueing to manufacturer specifications.

4. Replace Rotors (if necessary)

Sub-steps:
1. If the rotors are warped or uneven, remove the rotor by unscrewing any retaining screws and sliding it off the hub.
2. Install new rotors by aligning them with the hub and securing any retaining screws.

5. Reassemble and Test

Sub-steps:
1. Reinstall the wheel and hand-tighten the lug nuts.
2. Lower the vehicle and torque the lug nuts to manufacturer specifications.
3. Reconnect the battery and perform a brake pedal test to ensure proper pressure before driving.
