Solution

1. Preparation

Gather tools and parts required.
Ensure the vehicle is parked on a flat surface and the parking brake is engaged.
Wear safety gloves and goggles.

2. Remove Wheel

Sub-steps:
1. Loosen the lug nuts slightly while the vehicle is on the ground.
2. Lift 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 by unfastening the caliper bolts.
2. Slide the caliper off the rotor and hang it securely without stretching the brake line.
3. Remove the old brake pads from the caliper bracket.
4. Install new brake pads, ensuring they are seated correctly.
Tools Required: Socket set, torque wrench.

4. Inspect and Replace Brake Rotors

Sub-steps:
1. Check the rotor for warping using a runout gauge; replace if necessary.
2. Remove the rotor by unfastening the retaining screws (if present) and sliding it off the wheel hub.
3. Install the new rotor, ensuring it is clean and properly aligned.
Tools Required: Runout gauge, socket set.

5. Reassemble Components

Sub-steps:
1. Reattach the caliper, tightening bolts to the manufacturer’s specified torque settings.
2. Reinstall the wheel and hand-tighten the lug nuts.
3. Lower the vehicle and then fully tighten the lug nuts in a crisscross pattern.
Tools Required: Torque wrench.
