Solution

1. Preparation

Tools Required: Jack, jack stands, lug wrench, torque wrench, brake cleaner, safety glasses, gloves.
Safety Warnings: Always set the parking brake and use jack stands to secure the vehicle before working underneath.

2. Remove Wheel

Loosen the lug nuts slightly while the vehicle is on the ground.
Raise the vehicle with a jack and secure it on jack stands.
Remove the lug nuts completely and take off the wheel.

3. Inspect Brake Components

Visually check the thickness of the brake pads; replace if they are less than 3mm thick.
Inspect the brake rotors for scoring or warping; replace if necessary.
Check the caliper for proper operation and any leaks.

4. Replace Brake Pads (if needed)

Remove the caliper by unscrewing the caliper bolts (check torque specification).
Carefully slide the caliper off the rotor and suspend it without putting stress on the brake line.
Remove old brake pads from the caliper bracket.
Install new brake pads, ensuring they are properly seated.
Compress the caliper piston using a brake caliper tool or C-clamp to accommodate the new pads.

5. Reassemble and Test

Reattach the caliper over the new pads and secure it with caliper bolts (use specified torque).
Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle and tighten the lug nuts to the specified torque in a star pattern.
Pump the brake pedal to ensure proper pad seating and brake function before driving.
