Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is on a flat surface and the parking brake is engaged.
Disconnect the battery to prevent any electrical issues.

2. Remove Wheel

Tools Required: Jack, jack stands, lug wrench.
Loosen the lug nuts slightly before jacking the vehicle.
Raise the vehicle with the jack and secure it with jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect and Replace Brake Pads

Tools Required: Socket set, torque wrench.
Remove the caliper bolts using a socket wrench.
Carefully slide the brake caliper off the rotor and secure it to avoid stress on the brake line.
Remove the old brake pads from the caliper bracket.
Inspect the caliper for any damage; replace if necessary.
Install new brake pads, ensuring they are correctly oriented.

4. Inspect and Resurface/Replace Rotors

Check the rotors for damage; if scored or warped, they should be resurfaced or replaced.
Tools Required: Rotor puller, brake cleaner.
If resurfacing, clean the rotor surface with brake cleaner and follow manufacturer specifications for the resurfacing process.
If replacing, remove the rotor and install the new rotor, ensuring it is properly seated.

5. Reassemble Braking System

Reattach the caliper over the new pads and rotor.
Tighten the caliper bolts to the manufacturer’s torque specifications.
Reinstall the wheel and hand-tighten the lug nuts before lowering the vehicle.

6. Final Checks

Lower the vehicle and torque the lug nuts to the specified value.
Reconnect the battery and check for any warning lights.
Test the brakes by pressing the brake pedal several times to ensure proper engagement.
