- Brake Rotors: Rotate with the wheels and are squeezed by the brake pads.
- Brake Calipers: House the brake pads and apply pressure to the rotors.
- Brake Lines: Carry brake fluid to the calipers.
- Master Cylinder: Supplies brake fluid to the brake system.
- ABS (Anti-lock Braking System) Module: Prevents wheel lockup during hard braking.
Important Considerations: Brake pads and rotors should be replaced as a set for optimal performance. Inspect brake lines for leaks and ensure the brake fluid is clean and at the proper level.
Section 5: Electrical System
The electrical system powers various components in your Grand Cherokee.
- Battery: Provides electrical power to start the engine and operate accessories.
- Fuses: Protect electrical circuits from overloads.
- Relays: Control high-current circuits.
- Sensors (ABS, Crankshaft Position, Camshaft Position, etc.): Provide data to the engine control unit (ECU).
- Wiring Harness: Connects all electrical components.
- ECU (Engine Control Unit): Controls engine operation.
- Headlights: Provide illumination for driving at night.
- Taillights: Provide visibility to other drivers.
