Solution

1. Preparation

Tools Required: Jack, jack stands, wheel chocks, lug wrench, socket set, brake cleaner, and safety glasses.
Safety Warning: Make sure the vehicle is on a flat surface and secure it with wheel chocks before lifting.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Use a jack to lift the vehicle and secure it with jack stands.
Fully remove the lug nuts and take off the front or rear wheel to access the brake assembly.

3. Inspect and Replace Brake Pads

Remove the caliper by unscrewing the caliper bolts using a socket.
Lift 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.
Compare the old pads with new ones to ensure correct size.
Insert the new brake pads into the caliper bracket. Ensure they are correctly aligned.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged, remove them by unscrewing the rotor retaining screws (if equipped).
Clean the hub surface with brake cleaner.
Install the new rotor and secure it with the retaining screws.

5. Reassemble Braking System

Compress the caliper piston using a caliper tool or C-clamp until it is flush with the caliper housing.
Reposition the caliper over the new brake pads and rotor.
Reinstall the caliper bolts and tighten them to the manufacturer’s specifications (usually 20-30 Nm).
Reattach the wheel and hand-tighten the lug nuts.

6. Lower Vehicle and Test Brakes

Lower the vehicle back to the ground.
Tighten the lug nuts in a crisscross pattern to the specified torque (typically 100-120 Nm).
Pump the brake pedal several times to reposition the brake pads against the rotors.
Test the brakes gently to ensure proper operation before driving.
