Parking brake system, function description
The parking brake consists of brake oil tank, brake oil pump, brake
oil filter, accumulator charging valve, pressure sensors and parking
brake unit.
The brake oil pump pumps oil (from tank) which is cleaned in the oil
filter. The accumulator charging valve directs pressure to the accu-
mulators that store pressure. The parking brake unit is released with
pressure from the accumulators by the parking brake valve in the ac-
cumulator charging valve pressurizing the parking brake caliper.
Make-contact parking brake gives a signal so that the indicator light
parking brake is activated when the parking brake is applied.
