GF42.46-P-3000SL SBC function brake application in the event of system fault
Function
If faults occur in the system, the front axle brake circuit is braked hydraulically by the brake pedal. This process takes place without brake servo assistance.
In the event of a fault the two left front separation valves (A7/3y1) and right front separation valves (A7/3y2) remain open. The pressure is increased in the tandem master brake cylinder of the operating unit (1) by the brake pedal.
The spring assembly in the pedal pressure simulator (2) is compressed first.
After this the pressure builds up further and is led directly to the right front brake caliper (5a) and left front brake caliper (5b) of the front wheel brakes. The left front dividing piston (7) and right front dividing piston (8) prevent the brake fluid from flowing back and thus permit the pressure buildup.
