Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Gather the required tools: jack and jack stands, lug wrench, socket set, torque wrench, brake cleaner, and safety glasses.

2. Remove Wheel

Loosen lug nuts on the wheel while the vehicle is still on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the lug nuts completely and take off the wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Check the thickness of the brake pads; if they are below 3mm, replace them.
Remove the caliper by unbolting it from the bracket.
Slide the caliper off the rotor and support it with a bungee cord (do not let it hang by the brake line).
Remove the old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated in the bracket.

4. Inspect and Replace Rotors (if necessary)

Check the rotor surface for any significant grooves or warping.
If the rotors are damaged, remove them by unbolting the caliper bracket.
Clean the hub surface with brake cleaner.
Install new rotors, ensuring they are torqued to manufacturer specifications.

5. Reassemble Braking System

Reinstall the caliper over the new brake pads and rotor.
Torque the caliper bolts to the manufacturer’s specifications.
Reinstall the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Final Checks

Lower the vehicle from the jack stands.
Fully tighten the lug nuts in a star pattern to ensure even pressure.
Pump the brake pedal a few times to seat the brake pads against the rotors.
Test the brakes by applying them gently from a low speed before driving normally.
