INTENDED USE _____________________________________________________________
The G300 Brake Bleeder is a pneumatic diaphragm device designed to replace old brake fluid with new while
purging air bubbles from automotive hydraulic brake systems.
INSTALLATION INSTRUCTIONS _______________________________________________
1. Unpack and remove unit from shipping carton.
2. Inspect unit for any visible damage.
3. To install handle assembly to brake bleeder body; loosen thumb screw on handle receiver, insert handle, and
tighten thumb screw to secure handle.
4. Install a 1/4 NPT quick coupler nipple to the air inlet on the pressure regulator.
5. Fill with brake fluid following directions in Filling Fluid Reservoir section of OPERATING INSTRUCTIONS.
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.
Do not attempt to use this product for anything other than the intended
use.
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.
CAUTION
Excessive air pressure can result in serious damage to this diaphragm type brake
bleeder. Always follow the vehicle manufacturer’s recommendations and never
exceed 60 psi.

OPERATING INSTRUCTIONS ________________________________________________
Filling Fluid Reservoir
1. If connected, disconnect the air line from the air inlet. Open the air inlet valve to allow remaining air to
escape (Fig. 1).
2. Remove the bleeder hose from the top of reservoir by unscrewing (counterclockwise) the filler port
adapter under the red plastic cap and moving the hose away from the filler port (Fig. 2).
3. If refilling, the internal rubber diaphragm might be inverted inside the tank and must be gently pushed back
into place using the handle or a clean blunt instrument inserted through the filler port (Fig. 3).
Note: Using a sharp object or too much force can damage the rubber diaphragm.
Figure 1 Figure 2 Figure 3
4. Insert a plastic funnel tightly into the filler port and fill with brake fluid (Fig. 4). If the reservoir overfills and
fluid enters the funnel, use the suction syringe to remove any excess.
5. To re-install the bleeder hose on the filler port, place the filler port adapter on the filler port and turn it
clockwise. Hand tighten until snug.
6. Check the ball valve on the bleeder hose to ensure it is closed (turn clockwise until it stops).
Pressurizing Brake Bleeder
Note: Maximum pressure is 60 psi.
1. If the air inlet valve is open, close the valve and connect the air line.
2. To adjust the bleeder air pressure pull down on the regulator knob and turn (Fig. 5) until the desired
pressure is shown on the pressure gauge. Open the air inlet valve.
3. Insert the air purge valve assembly into the quick coupler on the end of the bleeder hose.
4. Open the bleeder valve and bleed air from the hose and reservoir by opening the purge valve (counter-
clockwise) over a container (Fig. 6). This is complete when the fluid produces a smooth steady stream.
5. To maintain constant bleeder pressure, leave the air line attached to the regulator. If desired, the air line
can be removed from the regulator. Close air inlet valve before removing air line to maintain pressure.

Brake Bleeding Procedure
1. Refer to vehicle service manual to determine appropriate pressure and adjust accordingly by adding or
removing pressure.
2. If a new master cylinder is being installed, bench bleed it before installation.
3. Fill the vehicle master cylinder to its maximum level or approximately ½” below master cylinder reservoir
rim. DO NOT fill to top. The air pocket left in the reservoir will act as a trap for any air bubbles present or
created during the bleeding process.
4. Determine appropriate adapter for the vehicle being serviced based on the Adapter Guide and install on
the vehicle master cylinder according to Brake Bleeder Adapter Instructions. If present, remove the air
purge valve assembly connect the bleeder hose to installed adapter.
5. Check all bleeder connections and vehicle’s brake lines for leaks. If a leak is detected; close the bleeder
valve, wrap a rag around the quick coupler to prevent drips and disconnect the quick coupler from the
adapter. Correct the problem before proceeding.
6. If the vehicle master cylinder and/or booster unit have bleed screws, bleed these prior to bleeding wheels.
Note: Always refer to vehicle service manual for proper bleeding procedure.
7. Apply the brake pedal. If the pedal feels soft, repeat bleeding operation.
8. When bleeding is complete, close the bleeder valve, wrap a rag around the quick coupler to prevent drips
and disconnect from adapter at master cylinder.
9. Remove the adapter from the master cylinder.
10. Check brake fluid level in the master cylinder and add or remove as needed for correct level.
11. Replace the master cylinder cover.
MAINTENANCE _____________________________________________________________
ALWAYS: Keep brake bleeder, adapters, and other accessories clean to prevent contaminants from
entering the brake fluid.
