Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Use wheel chocks to secure the vehicle.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly while the wheel is on the ground.
Lift the vehicle with the jack and secure it on jack stands.
Completely remove the lug nuts and take off the wheel.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; replace if below 3mm.
Tools Required: Socket set, brake caliper tool
Remove the caliper bolts using a socket.
Carefully slide the caliper off the rotor; support it to avoid straining the brake line.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are correctly oriented.

4. Inspect and Replace Brake Rotors

Measure rotor thickness with a micrometer; replace if below specification.
Tools Required: Torque wrench, brake rotor puller (if necessary)
Remove the caliper bracket if necessary to access the rotor.
Remove the rotor and replace it with a new one, ensuring it is properly seated.
Torque bolts to manufacturer specifications.

5. Reassemble and Test

Reattach the brake caliper and torque the bolts to specification.
Reinstall the wheel and hand-tighten lug nuts.
Lower the vehicle and fully tighten lug nuts in a crisscross pattern.
Pump the brake pedal a few times to seat the brake pads.
