Solution

1. Preparation

Gather tools and parts needed for repairs.
Disconnect the battery to prevent any electrical issues.
Allow the engine to cool down before working on it.

2. Inspect and Replace Belts

Inspect the Serpentine Belt:
- Remove the engine cover if necessary.
- Check for cracks, fraying, or excessive wear.
Replace if Damaged:
- Loosen the tensioner using a socket wrench.
- Remove the old belt and install the new one, ensuring correct routing.
- Tighten the tensioner to the manufacturer's specifications.

3. Brake System Inspection

Inspect Brake Components:
- Remove the wheel to access the brake assembly.
- Check brake pads for excessive wear and the condition of the rotors.
Replace Worn Components:
- If pads are worn down, remove the caliper and replace pads with new ones.
- Ensure rotors are not warped; replace if necessary.

4. Clean and Lubricate Components

Clean Affected Areas:
- Use brake cleaner or a degreaser to remove any residue.
Lubricate Moving Parts:
- Apply lubricant to any sticking or binding components, such as caliper slides.

5. Reassemble and Test

Reinstall any removed components, ensuring all bolts are torqued to specifications.
Reconnect the battery and start the engine, monitoring for any signs of continued issues.
