Solution

1. Preparation

Gather necessary tools and parts.
Ensure safety equipment is on hand (gloves, safety glasses).
Lift the vehicle using a jack and secure it with jack stands.

2. Remove Wheel

Use a lug wrench to loosen the lug nuts.
Remove the lug nuts and take off the wheel to access the brake assembly.

3. Inspect Brake Components

Brake Pads:
- Check pad thickness; replace if less than 3 mm.
- Look for signs of uneven wear or damage.
Brake Rotors:
- Measure rotor thickness with a micrometer.
- Inspect for grooves or warping; replace if necessary.

4. Replace Components

Brake Pads:
- Remove caliper bolts using a socket.
- Slide caliper off and remove old pads.
- Install new pads, ensuring correct orientation.
Brake Rotors:
- Remove retaining screws or clips if present.
- Slide off the old rotor and install the new one, securing it properly.

5. Reassemble and Test

Reattach the brake caliper and tighten bolts to manufacturer specifications (typically 25-35 ft-lbs).
Reinstall the wheel and lug nuts, tightening to specified torque (usually 80-100 ft-lbs).
Lower the vehicle and pump the brake pedal to seat the pads.
