Solution

1. Preparation

Gather tools and parts required for the repair (see below).
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Remove Wheel

Use a jack to lift the vehicle and secure it on jack stands.
Remove the lug nuts using a socket wrench and take off the wheel.

3. Inspect and Replace Brake Pads

Inspect Brake Pads:
- Check for thickness; if less than 3mm, replace.
- Look for uneven wear or cracking.
Replace Brake Pads:
- Remove the caliper bolts with a socket wrench.
- Slide the caliper off the rotor and hang it using a bungee cord to avoid strain on the brake line.
- Remove the old brake pads from the caliper bracket.
- Install new brake pads, ensuring they are seated correctly.
- Reattach the caliper and torque the bolts to manufacturer specifications (usually around 25-30 ft-lbs).

4. Inspect and Replace Brake Rotors (if necessary)

Inspect Rotors:
- Measure rotor thickness with a micrometer; replace if below minimum thickness.
- Check for grooves or scoring.
Replace Rotors:
- Remove the caliper bracket (if necessary) and slide the rotor off the hub.
- Clean the hub surface and install the new rotor.
- Reattach the caliper bracket and torque to specifications.

5. Reassemble

Reinstall the wheel and hand-tighten the lug nuts.
Lower the vehicle back to the ground and torque the lug nuts to specification (usually around 75-80 ft-lbs).

6. Brake Fluid Check

Check the brake fluid level and top off with the manufacturer's recommended fluid type if necessary.

Tools Required:

Jack and jack stands
Socket set
Torque wrench
Brake pad spreader tool (optional)
Brake cleaner
Bungee cord

Parts Required:

New brake pads
New rotors (if necessary)
Brake fluid (if low)

Estimated Repair Time: 2-4 hours

Safety Warnings:
