Solution

1. Preparation

Gather tools and materials needed.
Ensure the vehicle is parked on a level surface and secured with wheel chocks.
Disconnect the battery for safety.

Tools Required:

Jack and jack stands
Lug wrench
Torque wrench
Brake cleaner
C-clamp or brake tool
OBD-II scanner (if necessary)

2. Remove Wheel

Use the lug wrench to loosen the lug nuts slightly while the vehicle is still on the ground.
Lift 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

Remove the brake caliper by unscrewing the caliper bolts using the socket set.
Carefully slide the caliper off the rotor and support it with a bungee cord or rope, ensuring it does not hang by the brake line.
Inspect the brake pads for wear; if they are below the minimum thickness (usually 3mm), replace them.
To install new brake pads, compress the caliper piston with a C-clamp or brake tool, then insert the new pads into the caliper bracket.

4. Inspect and Replace Brake Rotors (if necessary)

If rotors are damaged or excessively worn, remove them by unscrewing the rotor screws (if equipped) and sliding them off the hub.
Clean the hub surface and install new rotors, ensuring they are seated properly.
Tighten rotor screws to the manufacturer’s specifications.

5. Reassemble Brake Components

Reattach the caliper over the new brake pads and secure it with the caliper bolts, tightening them to the specified torque.
Reinstall the wheel and hand-tighten the lug nuts.

6. Final Steps

Lower the vehicle back to the ground and tighten the lug nuts to the manufacturer’s torque specifications.
Reconnect the battery.
Pump the brake pedal several times before driving to ensure proper brake function.
