Parking Brake; General Information; Description - Chery A1 2009 Service Manual

Description

The base brake system consists of the following components:
• Power brake booster
• Master cylinder
• Brake pedal
• Front disc brakes

• Parking brake

• Brake tubes and hoses
• Rear drum brakes
The disc brake assembly consists of the following major components:
• Caliper
• Caliper adapter bracket
• Brake pads
• Rotor
CAUTION:
• Use DOT 4 brake fluid or equivalent from a tightly sealed container. Do not use petroleum-based
fluids, which would cause seal damage in the brake system.
• Brake fluid will damage painted surfaces. If brake fluid is spilled on any painted surfaces, wash
it off immediately with water.
• Never use gasoline, kerosene, alcohol, motor oil, transmission fluid or any fluid containing min-
eral oil to clean system components. These fluids damage rubber cups and seals.
• During service procedures, grease or any other foreign material must be kept off the caliper
assembly, brake pads, brake rotor and external surfaces of the hub.
• When handling the brake rotor and caliper, be careful to avoid damaging the brake rotor and
caliper, and scratching or nicking the brake shoe lining.
Operation
Applying the brake pedal uses lever action to push a rod into the brake booster, which through the use of vacuum,
boosts the force of the rod and then transmits this force into the master cylinder. This produces hydraulic pressure in
the master cylinder. On vehicles not equipped with an Antilock Brake System (ABS), the hydraulic pressure is trans-
mitted by brake fluid through the brake tubes to the individual brake calipers or wheel cylinders. On vehicles
equipped with ABS, the hydraulic pressure is transmitted by brake fluid through the brake tubes to the ABS Hydraulic
Control Unit (HCU), which then distributes that pressure to the individual brake calipers and wheel cylinders. The
brake calipers use hydraulic pressure to apply the brake pads. The application of the brake pads or shoes will cause
the rotation of the wheels to slow or stop depending on how much brake pressure is applied. The parking brakes
carry out the same function except that they are mechanically actuated by a cable that connects only to the rear
brakes.
