Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Wear safety gloves and goggles for protection.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench
Loosen the lug nuts slightly before lifting the vehicle.
Raise the vehicle using a jack and secure it with jack stands.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Pads

Check the thickness of the brake pads using a caliper.
If the pads are less than 3 mm thick, they need to be replaced.
Inspect the pads for any cracks or uneven wear.

4. Replace Brake Pads (if necessary)

Tools Required: Socket set, brake caliper tool, torque wrench
Remove the caliper bolts using a socket set and carefully slide the caliper off the rotor.
Support the caliper with a bungee cord or hanger to avoid straining the brake line.
Remove the worn brake pads from the caliper bracket.
Install new brake pads in the bracket, ensuring they are seated correctly.
Compress the caliper piston using a brake caliper tool to create space for the new pads.
Reinstall the caliper over the new pads and secure it with bolts.
Torque the caliper bolts to the manufacturer’s specifications.

5. Reinstall Wheel

Place the wheel back onto the hub and hand-tighten the lug nuts.
Lower the vehicle from the jack stands and remove the jack.
Torque the lug nuts to the manufacturer’s specifications in a star pattern.

6. Final Checks

Pump the brake pedal a few times to ensure proper pad seating.
Test the brakes at low speeds to ensure proper operation.
