Solution

1. Prepare the Vehicle

Ensure the vehicle is parked on a level surface and turned off.
Disconnect the high-voltage battery to prevent any electrical hazards.
Wear safety gloves and goggles.

2. Inspect and Clean the Brake System

Tools Required: Jack, jack stands, lug wrench, brake cleaner, torque wrench.
Jack up the vehicle and securely place it on jack stands.
Remove the wheel to access the brake components.
Inspect brake pads and rotors for excessive wear or burning.
Clean the brake components using brake cleaner to remove any debris or residue.
If brake pads are worn down, replace them with new ones, ensuring proper torque specifications are followed during reinstallation.

3. Inspect Electrical Connections

Tools Required: Multimeter, basic hand tools (screwdrivers, pliers).
Visually inspect all high-voltage wiring for signs of damage or corrosion.
Use a multimeter to check the voltage at battery connections for proper readings.
Tighten any loose connections and replace any damaged wiring or components.

4. Check Fluid Levels

Tools Required: Fluid containers, funnel.
Check the brake fluid reservoir and top off if necessary with the manufacturer's recommended fluid.
Inspect the coolant level and top off if low, ensuring the correct coolant type is used.
