Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to ensure safety.

2. Inspect and Replace Brake Components

Tools Required: Jack and jack stands, lug wrench, socket set, torque wrench.
Lift the vehicle using a jack and secure it on jack stands.
Remove the wheels using a lug wrench.
Inspect the brake pads and rotors for signs of damage or wear. If they are burnt or worn down, proceed to replace them:
- Remove the caliper bolts using a socket set.
- Remove the caliper and hang it securely (do not let it hang by the brake line).
- Replace the brake pads and inspect the rotors for scoring.
- Reinstall the caliper and torque bolts to manufacturer specifications.

3. Inspect and Replace Drive Belts

Tools Required: Socket set, torque wrench.
Locate the drive belt and inspect for cracks or fraying.
If damaged, remove the old belt by loosening the tensioner using a socket.
Install the new belt according to the routing diagram found on the engine bay.
Ensure proper tension and torque any necessary bolts.

4. Tire Inspection and Replacement

Tools Required: Tire pressure gauge, lug wrench.
Check tire pressure and adjust to manufacturer specifications.
Inspect tires for uneven wear or damage. If necessary, replace tires.
Rotate tires if they are unevenly worn to ensure balanced performance.
