Description & Operation

NOTE: Components common to Anti-Lock Brake System (ABS) and non-ABS systems are covered in this article. For information on specific ABS components, see ANTI-LOCK BRAKE SYSTEM article.

Front brakes are disc and rear brakes are drum. Disc brakes are continually self-adjusting. Rear brakes are self adjusting. Parking brake is cable operated and should not need adjustment.

Hydraulic system is diagonally split, so system will still operate if one side loses pressure. Master cylinder has fluid level sensor located in reservoir. Proportioning valves are integral of master cylinder. Proportioning valves regulate hydraulic pressure between rear and front brakes for optimum braking.

BRAKE warning light comes on when one or more of the following conditions exist:

Parking brake is applied or not fully released.
Fluid level in master cylinder reservoir is low.
During engine cranking. A bulb check is performed to indicate that the warning circuit is operational.
