Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a flat surface and engage the parking brake.
Place wheel chocks behind the rear tires for safety.

2. Raise Vehicle

Use a jack to lift the front of the vehicle and securely place jack stands under the frame.
Remove the front wheels using a lug wrench.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Remove the caliper bolts using a socket set.
- Slide the caliper off the rotor and support it (do not let it hang by the brake line).
- Check the brake pads for thickness; if less than 3mm, replace.
Replace Brake Pads:
- Remove the old pads from the caliper bracket.
- Install new pads, ensuring they are correctly oriented and seated.
- Apply brake grease to the backing of the pads (if specified by manufacturer).

4. Inspect and Replace Brake Rotors (if necessary)

Check Rotors:
- Measure rotor thickness using a micrometer; replace if below minimum specs.
- Look for signs of scoring or warping.
Replace Rotors:
- Remove the rotor retaining screws (if applicable).
- Slide off the old rotor and replace with a new rotor.
- Tighten the rotor retaining screws to the manufacturer’s specifications.

5. Reassemble and Lower Vehicle

Reinstall the caliper over the new pads and rotor.
Tighten caliper bolts to the manufacturer’s torque specifications.
Reattach the front wheels and lower the vehicle to the ground.

6. Final Check

Pump the brake pedal several times to seat the brake pads.
Check brake fluid level and top off if necessary.
