MODEL G300
Brake Bleeder

Rev070904

P/N: 81-0035B

NOTE:

THE G300 BRAKE BLEEDER WILL CEASE TO OPERATE WHEN ALL OF THE BRAKE
FLUID IS EXPELLED AND THE DIAPHRAGM IS AT THE TOP OF THE TANK. THE
DIAPHRAGM MUST BE PUSHED DOWN TO THE BOTTOM OF THE TANK BEFORE THE
BLEEDER WILL OPERATE AGAIN.

When the G300 BRAKE BLEEDER is empty of brake fluid, slowly release the air pressure
using the air valve at the bottom of the tank. Remove the air valve when all of the air has
been released.

The internal rubber diaphragm will be inverted inside the tank and must be gently pushed back
into place using a blunt instrument. The Bleeder can now be refilled with brake fluid and the
air valve can be replaced.

Before operating the G300 Brake Bleeder, install the handle assembly to the Brake Bleeder.

OPERATION_____________________________________________

1) Release air cap at bottom of bleeder, allowing air to escape while filling with brake fluid.

2) If refilling, the internal rubber diaphragm will be inverted inside the tank and must be gently
pushed back into place using a blunt instrument.

3) Press plastic funnel tightly into filler hole and fill with brake fluid. If you overfill the brake
bleeder and fluid enters the funnel, use the suction syringe to remove the excess.

4) Install expanding filler plug assembly into bleeder filler hole and lock in place by turning
filler plug washer 90° (item 18, repair parts) and tighten wing nut.

5) Tighten air release cap at bottom of bleeder and inflate bleeder to 15 pounds bleeding
pressure.

CAUTION

Before using this product, read and fully understand the operating
instructions and all decals on the product. This is necessary to
prevent injury to the operator and damage to the product.


Refer to vehicle service manual for proper bleeding procedure.


Do not use Aviation or Hydraulic Fluid with this product. Product

Damage May Result.


Avoid allowing Brake Fluid to contact vehicle finished surfaces.

Damage to the surface finish may result.

Always wear appropriate eye protection.

NOTE:

BRAKE FLUIDS ARE EASILY AGITATED AND THEREFORE SHOULD BE BLED THROUGH
THE CAR BRAKE SYSTEM WITH THE LOWEST POSSIBLE BLEEDING PRESSURE TO
PREVENT AIR BUBBLES. IF HIGHER PRESSURES ARE NEEDED DURING THE
BLEEDING OPERATION TO PURGE AIR FROM A HIGH POINT IN A WHEEL CYLINDER,
OPEN ONE WHEEL CYLINDER BLEED SCREW AT A TIME AND HAVE SOMEONE PUMP
THE BRAKE PEDAL VIGOROUSLY A FEW TIMES. THIS CAUSES TURBULENCE IN THE
CYLINDER, FORCING AIR FROM THE WHEEL CYLINDER.

6) Install the automotive master cylinder fill nozzle in the end of the hose. Open the shut-off
valve and bleed air from bleeder and reservoir hose assembly into plastic cup. When fluid
flows clear of air bubbles, set air pressure according to the specifications listed on the next
page. The unit is now ready to attach to the car master cylinder

7) Before installing proper master cylinder bleeding adapter, bring fluid level up to
approximately ½ below the master cylinder reservoir top rim. Do not fill master cylinder to
the top, as this air pocket acts as a trap for any air bubbles that might enter or be created
in the bleeding operation.

8) Disconnect the automatic master cylinder fill nozzle and attach the bleeder hose on to the
appropriate master cylinder adapter on car. (See the adapter guide on the last two pages
of this manual.)

9) Check hook-up connections and car brake line system for leaks.

10) Some master cylinders and booster units have bleed screws. Bleed these first, then bleed
each wheel cylinder in the following order: right rear, left rear, right front and left front.
This applies not only to dual brake systems, but others as well. Always refer to vehical
service manual for proper bleeding procedure.

11) Check brake pedal. If pedal has too much soft cushion, repeat bleeding operation.

12) Wrap a cloth or rag around the quick coupler connection before disconnecting to avoid
fluid spill, which might damage paint finish.

BLEEDING SPECIFICATIONS_______________________________










DRUM BRAKES:

Pressurize Brake Bleeder to 15 to 25 p.s.i.

DRUM/DISC BRAKES:

American
Motors
10
to
20
p.s.i.


Chrysler Corporation

35 p.s.i.


Ford Motor Company

10 to 30 p.s.i.
General
Motors
20
to
25
p.s.i.


Most Import Cars

20 to 25 p.s.i.

Most drum/disc brake cars will have a metering valve or combination valve. This valve must
be manually overridden. If this is not possible, the bleeder pressure should not exceed the
metering valve pressure.

Some cars have pressure differential valves that activate a dash panel warning light. This
valve, on some cars, must be reset.

Bench bleed new master cylinders before installation.

ALL WHEEL ANTI-LOCK BRAKE SYSTEMS (ABS):

Attach bleeder adapter to reservoir cap opening. A minimum of 35 p.s.i. must be maintained
on system with brake pedal released and ignition off. Open the rear bleeder screw on each
caliper for 10 seconds at a time.

When air is out and there is a free flow of fluid, close bleeder screws and place ignition switch
in run position. Pump brake pedal several times to complete bleeding procedure.

NOTE:

DO NOT OVERFILL MASTER CYLINDER, FILL TO MAXIMUM LEVEL ONLY. USE
BLEEDING SEQUENCE CALLED FOR BY VEHICLE MANUFACTURER.




CAUTION
Excessive air pressure can result in serious damage
to this diaphragm type brake bleeder.
