2. INTRODUCTION
Professional one man brake and clutch bleeder that uses air from the vehicle tyre. Reservoir holds 1.5ltr of hydraulic fluid - flush the entire
system with one fill without the risk of running the reservoir dry. Maximum pressure of 30psi makes the unit suitable with ABS systems. Features a
fluid shut off valve to prevent accidental spillage and air pressure release valve. Fitted with Ø45mm cap with 90° angled connector which is suitable
for most European models. For other applications order optional Brake Reservoir Cap 45mm Straight Connector - Model No. VS820SA (see fig.6) or

4. OPERATION
4.1. BRAKE BLEEDING PROCEDURE
4.1.1. Refer to the vehicle manufacturer’s instructions for brake bleeding and wheel sequence before proceeding. If no specific instructions
from the vehicle manufacturer exist, follow the instructions detailed below.
WARNING! Familiarise yourself with the hazards of brake uid - read manufacturer’s instructions on the container.
NOTE: Ensure that the brakes are adjusted before proceeding with bleeding the brakes.
4.1.2. For vehicles fitted with servo assisted brakes, pump the brake pedal two or three times with the engine switched off to evacuate the
air from the servo.
4.1.3. Remove the reservoir cap from the vehicle’s brake master cylinder, select and fit the master cylinder reservoir adaptor or universal
adaptor to the vehicle and couple the clear hose of the automatic brake bleeder (see figs.3, 5 and 6). Make sure the fluid shut-off
valve is in the closed position, see fig.3.
4.1.4. Adjust the tyre pressure, of one of the vehicle’s tyres, or use a spare wheel, to a maximum of 30 psi and connect the automatic brake
bleeder, (see fig.1).
4.1.5. Pressure test the bottle with no brake fluid to ensure that the bottle has no leaks and then release the pressure, by disconnecting from the
tyre then releasing the pressure relief valve on top of the bottle (see fig.2). Fill the pressure bottle with new clean brake fluid.
WARNING! DO NOT overtighten 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.
4.1.6. Ensure that the pressure relief valve (fig.2) on the top of the bottle is in the closed position (screwed fully clockwise), hang under the
open bonnet and connect the air hose to the tyre. Open fluid shut off valve. Check to ensure there are no leaks.
NOTE: The 30 psi quoted is as a guide only, pressures as low as 10 psi can successfully bleed the brakes.
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. Alternatively, use Sealey Brake Bleeder Bottle VS0212. Loosen the bleed nipple (fig.4) to allow the old brake fluid to flow
into the container, when the fluid is clean and free from air re-tighten the nipple. 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, disconnect from the tyre, and release the
pressure release valve, before replenishing the brake fluid.
4.1.8. When the bleeding operation is complete, disconnect from the tyre and close fluid shut off valve BEFORE removing from the brake
master cylinder.
If required top up the brake fluid in the reservoir (master cylinder) to the maximum level and replace the original reservoir cap.
4.1.9. . 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 BRAKING 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.
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
4.4.1. 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.
