Scheme 152

The brake system can be divided into following main components

1. Wheel braking system
2. Hydraulic braking system
3. Parking brake system
4. ABS, EBD and anti-spin systems

Certain components are located differently in the engine compartment depending if the car is left or right-hand drive.

The main systems consist of the following main components

Wheel braking system

1. Front brake caliper and pad (1)
2. Front brake disc (2)
3. Rear brake caliper and pad (3)
4. Rear brake disc (4)

Hydraulic braking system

1. Brake fluid reservoir and level sensor (5)
2. Master cylinder (6)
3. Power brake booster overload relay (7)
4. Brake pedal and stop (brake) light contact (8)
5. Brake lines (9)
6. Brake circuit warning indicator (10)

Parking brake system

1. Parking brake lever (12)
2. Brake wires (13)
3. Brake shoes (14)
4. Parking brake lever warning lamp (15)

ABS, EBD and anti-spin systems

1. Control module for ABS, EBD and anti wheelspin (16)
2. ABS warning lamp (20)
3. Anti-wheelspin warning lamp (Only cars with anti wheelspin) (21)
4. Anti-wheelspin switch (Only cars with anti wheel spin) (22)
5. ABS hydraulic modulator with pump motor and valves (17)
6. Front wheel sensor with pulse wheel (18)
7. Rear wheel sensor with pulse wheel (19)
