Solution

1. Preparation

Gather tools and materials.
Ensure the vehicle is parked on a level surface, and engage the parking brake.
Disconnect the battery for safety if working on electrical components.

2. Brake Inspection and Repair

Remove Wheel:
- Use a jack to lift the vehicle and secure it with jack stands.
- Remove the wheel using a socket set.
Inspect Brake Components:
- Check brake pads for wear; replace if less than 3mm thick.
- Inspect rotors for scoring or warping; replace if necessary.
Replace Brake Pads and Rotors (if necessary):
- Remove caliper bolts using a wrench.
- Carefully slide the caliper off the rotor and hang it using a bungee cord (do not let it dangle by the brake line).
- Remove the old pads and install new ones, ensuring proper alignment.
- If replacing rotors, remove the old rotor and install the new one, securing it with bolts to the specified torque (usually around 80-100 Nm).
Reassemble:
- Reattach the caliper and secure it with the bolts, torquing them to the manufacturer's specifications.
- Reinstall the wheel and lower the vehicle.

3. Drivetrain Inspection and Repair

Check Transmission Fluid:
- Remove the transmission dipstick (if applicable) and check fluid level and condition. Fluid should be bright red and free of debris.
- If low, add the appropriate type of transmission fluid as specified in the owner’s manual.
Inspect Drivetrain Components:
- Check for any loose or damaged components, including CV joints, driveshaft, and differential.
- Replace any damaged parts identified during inspection.
