Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, multimeter, brake fluid tester.
Ensure the vehicle is parked on a flat surface and the engine is turned off.
Allow the engine to cool before inspection to prevent burns.

2. Inspect Engine Compartment

Remove the engine cover (if applicable) using a socket set.
Check for oil leaks or burnt oil on hot engine parts; clean any areas as needed.
Look for any rubber hoses or wiring that may have been damaged.

3. Check Brake Components

Raise the vehicle using a jack and secure it with jack stands.
Remove the wheels using a socket set.
Inspect brake pads for wear; replace if less than 3mm thick.
Check rotors for scoring or cracking; resurface or replace if necessary.
Inspect calipers for proper operation; replace if leaking or stuck.

4. Examine Electrical System

Use a multimeter to check for voltage drops in wiring harnesses, especially near heat sources.
Inspect connectors and wiring for signs of melting insulation; repair or replace as needed.
Ensure that all electrical components are functioning correctly, replacing any faulty parts.

5. Test Brake Fluid

Remove the brake fluid reservoir cap and check fluid condition.
If fluid appears dark or contaminated, perform a brake fluid flush.
Refill with manufacturer-recommended brake fluid and bleed the brake system to remove air.
