WARNING! DO NOT over-tighten the pressure bottle cap. Check that the seal is
‰
correctly seated in the cap before use and screw onto the pressure bottle until contact
with the seal is achieved, tighten no more than 1/8th of a turn after this contact point.
4.1.5.
Ensure that the regulator (fig.2) on the top of the bottle is in the closed position, connect
the air line to the tyre. Ensure that the pressure bottle is in safe upright position.
4.1.6.
Slowly open the regulator anti-clockwise to pressurise the brake system, checking to
ensure there are no leaks.
NOTE: The 20 psi quoted is as a guide only, pressures as low as 10 psi can
successfully bleed the brakes, adjust the regulator valve accordingly to the vehicle
being worked on.
4.1.7.
Starting from the bleed nipple furthest away from the master cylinder, attach a bleed tube
and place the other end into a suitable container. Loosen the bleed nipple (fig.3) to allow
the old brake fluid to flow into the container, when the fluid is clean and free from air
re-tighten the nipple.
4.1.8.
Repeat the operation for the remaining bleed nipples in the sequence recommended by
the manufacturer.
NOTE: Ensure that the pressure bottle does not run out of brake fluid, if topping up is
required, close the regulator and disconnect from the tyre, before replenishing the
brake fluid.
4.1.9.
When the bleeding operation is complete, disconnect from the tyre BEFORE removing
from the brake master cylinder.
4.1.10.
If required top up the brake fluid in the reservoir to the maximum level and replace the
original reservoir cap.
4.1.11.
Re-pressurise the tyre to its normal operating pressure.
NOTE: When brake bleeding and/or fluid changing is complete, test the action of the
brake pedal to ensure that the brakes are working and are not spongy before using the
vehicle on the road.
4.2.
TANDEM MASTER CYLINDER BRAKE SYSTEMS
4.2.1.
Some vehicles require two lines to be bled simultaneously (normally one front and one
rear), in this situation open both bleed nipples and control the flow using the regulator on
the top of the pressure bottle.
4.3.
UNCOMMON BRAKE SYSTEMS
4.3.1.
In some cases the master cylinder outlet is below the inlet, this may require pumping the
pedal once or twice in conjunction with the pressure bleed to remove any trapped pockets
of air. Alternatively the vehicle can be jacked up to raise the outlet.
4.4.
CLUTCH BLEEDING PROCEDURE
Refer to the relevant vehicle manufacturer's instructions for clutch bleeding procedure. If no
specific instructions from the vehicle manufacturer exist, the same procedures as for brake
bleeding should be followed.
5.
MAINTENANCE
5.1.
Ensure that the unit is de-pressurised before carrying out any maintenance and drain all fluids from the pressure bottle and tubes.
Clear up any split brake fluid and wipe down with a clean cloth. Store in a clean, dry and childproof location.
