Braking System
The braking system for the Super Cruiser is
hydraulically driven. The hydraulic pump mounted
on the engine supplies oil to the braking circuit and
gives priority to the brakes once the accumulators
are fully charged. Hydraulic pressure goes from the
accumulators to the foot pedal and then to the wet
brake system in the front and rear axles.
The hydraulic pressure drives a wedge into the disk
body and clutch disks, and on the rear axle when
there is no pressure, it acts as a park brake.
There is two brake control cylinders on each axle.
On the rear, the brake control cylinders also operate
the park brake. The park brake will always be applied
when there is no hydraulic pressure going to the
park brake chamber in the brake control cylinder.
There is no adjustment for the service brake
function, if the braking performance deteriorates and
it take more pressure to stop, the clutch disks may
need replacing.
Bleeding the Brakes
The braking system is a hydraulic configuration. The
front and rear brakes are operated from the main
hydraulic pressure system.
To bleed the brakes, ensure that the wheels are
chocked front and rear.
Each brake control cylinder and function must then
be bled separately.
The method used to bleed the service brakes
manually is to:
1. Connect a clear plastic tube to the bleed screw
and place the opposite end of the tube into a
container.
NOTE: The system should be bled until no more air
bubbles appear in the bleed line.
NOTE: It is recommended that during this process
the person bleeding the brakes wear suitable eye
protection.
2. With an assistant in the cabin, start the engine
(ensure no person is under the machine and the
transmission is in neutral).
3. In the cabin, depress the brake pedal and hold.
4. Loosen the bleed screw and when there is no air
and only a continuous stream of fluid in the clear
hose, re-tighten the bleed screw before allowing
the pedal to return to its released position.
3. Repeat this procedure for each of the other brake
control cylinder assemblies.
In case of re-assembly of the brake discs kit and brake body, due to a substitution or during extraordinary maintenance which implies
its disassembly, we recommend to put all the friction discs in phase, so that the holes for oil passage can coincide and to put all the
intermediate discs in phase, as per enclosed scheme , in order to grant a correct brake operation.
