Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to prevent electrical shock.

2. Inspect and Repair Wiring

Tools Required: Wire cutters, electrical tape, heat shrink tubing, soldering iron.
Examine all wiring in the engine bay for damage or wear.
Repair any damaged wires by cutting out the bad section and splicing in new wire, securing with solder and heat shrink tubing.
Use electrical tape to insulate any exposed connections.

3. Brake System Inspection and Repair

Tools Required: Jack and jack stands, brake cleaner, torque wrench.
Raise the vehicle and remove the wheels to access the brake components.
Inspect brake pads for wear or burning; replace if necessary.
Check calipers for sticking; lubricate or replace as needed.
Reassemble the brake system, ensuring all bolts are torqued to manufacturer specifications.

4. Fluid Checks and Replacement

Tools Required: Fluid extraction pump, funnel.
Check the transmission fluid level; if low or burnt, drain and replace with manufacturer-recommended fluid.
Inspect the coolant level; top off if necessary and check for leaks in hoses or the radiator.
