Replace Gaskets and Seals:
1. If leaks are found, remove the faulty gasket or seal.
2. Clean the mating surfaces and install a new gasket or seal, tightening to manufacturer specifications.

3. Addressing Brake Overheating

Inspect Brake Components:
1. Remove the wheel to access the brake caliper and rotor.
2. Check brake pads for excessive wear and heat discoloration.
Replace Brake Pads and Resurface Rotors:
1. Remove the caliper and old pads.
2. Replace with new brake pads and resurface or replace rotors as needed, ensuring proper torque specifications are followed.

4. Electrical Inspection

Examine Wiring:
1. Check for damaged or burnt wires in the engine compartment and under the dashboard.
2. Repair or replace any damaged wiring.
Ensure Proper Connections:
1. Tighten any loose electrical connections and inspect fuses.

5. Final Assembly
