Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and securely lifted using jack stands.
Disconnect the battery for safety.

2. Remove Wheel Assembly

Use a lug wrench to loosen lug nuts on the wheel.
Remove the lug nuts and take off the wheel.
Tools Required: Lug wrench, jack stands, hydraulic jack.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper mounting bolts.
Carefully slide the caliper off the rotor, ensuring the brake line is not stressed.
Remove the old brake pads from the caliper bracket.
Measure the thickness of the new brake pads against manufacturer specifications.
Install the new brake pads into the caliper bracket.
Tools Required: Socket set, brake pad spreader.

4. Inspect and Replace Brake Rotors (if necessary)

Remove the rotor by unscrewing any retaining screws or bolts.
Inspect the rotor for scoring; if damaged beyond spec, replace it with a new rotor.
Clean the new rotor with brake cleaner to remove any protective oil.
Install the new rotor and secure it using the retaining screws.
Tools Required: Torque wrench, socket set.

5. Reassemble Brake Components

Reinstall the caliper over the new brake pads and rotor.
Tighten the caliper mounting bolts to the manufacturer’s specified torque.
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to the specified value.
Tools Required: Torque wrench.

6. Final Checks

Reconnect the battery.
Pump the brake pedal a few times to ensure the brake pads seat properly.
Inspect for any leaks or abnormal noises.
