Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface, and the engine is off.
Jack up the vehicle and secure it on jack stands.
Remove the wheel to access the brake assembly.

2. Inspect Brake Pads

Use a caliper to measure the thickness of the brake pads.
- Minimum thickness should be at least 3mm; replace if below this.
Check for uneven wear on the pads which may indicate other issues.

3. Remove Old Brake Pads

Locate the caliper mounting bolts and remove them using a socket wrench.
Carefully slide the caliper off the rotor; do not let it hang by the brake line.
Remove the old brake pads from the caliper bracket.

4. Install New Brake Pads

Apply brake grease to the back of the new brake pads to prevent noise.
Slide the new pads into the caliper bracket.
Reattach the caliper over the new pads and tighten the mounting bolts to the manufacturer’s torque specifications (typically 20-30 ft-lbs, but check the specific model).

5. Reassemble and Test

Reinstall the wheel and hand tighten the lug nuts.
Lower the vehicle and torque the lug nuts to the manufacturer's specifications.
Pump the brake pedal a few times to ensure the pads are seated properly.
Test drive the vehicle to confirm proper braking function.
