Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, socket set, torque wrench, brake cleaner, gloves, safety goggles.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery if working on electronic components.

2. Lift and Secure Vehicle

Loosen lug nuts on the affected wheel slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Remove the wheel to access the brake components.

3. Remove Brake Caliper

Use a socket set to remove the caliper bolts.
Carefully slide the caliper off the rotor; do not disconnect the brake line unless necessary.
Support the caliper using a bungee cord or similar, to avoid straining the brake line.

4. Inspect and Replace Brake Pads

Remove the old brake pads from the caliper bracket.
Inspect the pads for wear; replace if they are less than 3mm thick.
Apply brake cleaner to the pads and caliper bracket.
Install new brake pads into the caliper bracket.

5. Inspect and Replace Brake Rotors (if necessary)

Check the rotor surface for grooves or warping; replace if damaged.
If replacing, remove the caliper bracket and rotor.
Install new rotors, ensuring they are clean and free of debris.
Torque rotor mounting bolts to manufacturer specifications.

6. Reassemble Brake Components

Reinstall the brake caliper over the new pads and rotor.
Tighten caliper bolts to the specified torque.
Reinstall the wheel and torque lug nuts to specifications.

7. Lower Vehicle and Test Brakes

Remove jack stands and lower the vehicle.
Reconnect the battery if disconnected.
Test the brakes by gently pressing the pedal to ensure proper engagement before driving.
