Solution

1. Preparation

Gather Tools and Parts: Ensure you have all necessary tools and replacement parts ready before starting the repair.
Safety Precautions: Disconnect the negative battery terminal to prevent electrical shock.

2. Addressing Engine Issues

Check for Oil Leaks:
- Inspect the oil filter and oil pan for leaks.
- Replace any faulty seals or gaskets as needed.
Change Engine Oil:
- Drain the old oil and replace it with the manufacturer-recommended oil.
- Dispose of old oil properly.

3. Brake System Inspection and Repair

Remove Wheel:
- Use a jack to lift the car and secure it on jack stands.
- Remove the wheel to access the brake components.
Inspect and Replace Brake Pads:
- Measure the thickness of the brake pads. If they are worn down, replace them.
- Clean the brake caliper and rotor surfaces before reassembly.
Reassemble and Test:
- Reattach the wheel, lower the vehicle, and pump the brake pedal to ensure proper contact.

4. Electrical System Repair

Inspect and Repair Wiring:
- Examine all wiring for wear, frays, or burnt sections.
- Replace any damaged wires with the appropriate gauge wire.
Check Battery and Alternator:
- Test the battery voltage (should be around 12.6V when off and 13.7-14.7V when running).
- Replace the battery if it doesn’t hold charge or the alternator if it’s not charging.
