Extracting the Old Brake Fluid
1. Ensure that the vehicle is turned o. Turn it to
Neutral for manual transmissions, or turn it to
Park for automatic transmissions. Activate the
parking brake.
2. Choose an air intake (F or G) and securely
connect it to the air valve inlet on the vacuum
brake bleeder.
3. Secure the extractor hose (C) to the inlet port.
4. Remove the cap from the master cylinder
reservoir and insert the extractor hose.
5. Connect an air compressor to the air valve inlet
on the brake bleeder and set the compressor.
The recommended pressure range is 70−170
psi (4.8−11.7 bar).
6. Turn on the air control valve and activate the air
compressor to extract the old uid.
7. After extraction, remove the extractor hose,
switch o the air compressor, and turn o the air
control valve.
• ALWAYS follow your vehicle manufacturer's service manual for the recommended type and
amount of transmission uid.
• Put on your PPE, always including ANSI-approved safety glasses and work gloves.
• Raise your vehicle if needed, using appropriate safety stands to prevent potentially fatal
accidents.
• ALWAYS e n s u r e t h a t th e b r a ke u i d t o b e a d d e d ma tc he s yo u r v e h i c le’s sp ec i c r e qu i r e m e n t s
to prevent damage to the braking system.
• DO NOT open the vacuum brake bleeder’s pressure release valve during use. Doing so
will introduce air into the system, causing reduced eciency, malfunction, or even safety
hazards like explosions.
• ALWAYS work in a well-ventilated area, as brake uid can emit harmful vapors.

Note: ALWAYS keep the reservoir lled to prevent air from entering the brake system.
Bleeding the Brake Fluid
1. Remove the extractor hose and connect the bleeding hose (D) to the inlet port.
2. Locate the tire farthest from the reservoir and identify the bleed screw near it.
3. Remove the bleed screw cap and attach the bleeding hose with the adapter to the screw.
4. Use a box-end wrench (not included) to loosen or open the bleed screw.

Maintenance
• Use detergent and water to rinse the kit and clean the inner surfaces of the hoses. Dry the kit
COMPLETELY before continued use.
• Check for loose connections, wear, and damage before and after each use. Tighten, repair, or
replace ANY aected or damaged components before further use. ONLY use identical parts
as replacements.
• If this kit will not be used for an extended period, store it in a cool and dry location, away from
direct sunlight and out of children’s reach.
8. Start from the tire farthest from the reservoir to the one nearest to it. Repeat the process for
each wheel in succession.
Note: While the uid is being changed, regularly check the level in the relling bottle.
9. After bleeding, switch o the air compressor and disconnect it from the brake bleeder. Remove
the top adapter of the bleeding hose from the inlet port. Pour the old brake uid into the waste
oil barrel.
• ALWAYS wear proper PPE, such as gloves and goggles, when handling waste brake
uid to prevent exposure to hazardous substances.
• Hazardous waste disposal regulations vary by region and require spent brake uid to be
disposed of according to local standards.
• NEVER mix waste brake uid with other chemicals as this may cause a dangerous
chemical reaction.
• Ensure that waste brake uid is stored in sealed containers away from sources of ignition
and children to prevent accidents.

Troubleshooting
Problems Solutions
Slow Extraction
Speed
Check for blockages or obstructions in the tubes; Clean or replace
any blocked components.
Verify the air pressure source to ensure it is within the specified
range for the equipment.
Inspect the hoses for twists or bends that may aect ow speed.
Leakage Issues
Check the tightness of hose connections to ensure there are no
loose ttings.
Inspect the hoses, tubes, adapters, clamps, and other components
for damage or wear; Promptly replace any affected or damaged
components.
Ensure that the clamps are securely fastened to the hose
connections.
Air Remaining in the
Brake System
Ensure to start bleeding from the wheel farthest from the brake
master cylinder and work your way closer.
Ensure there are no damaged or loose hoses. Tighten all
connections securely.
Problems with brake pads or discs can indirectly aect the bleeding
process. Ensure all brake components are in good condition.
Relling Bottle Not
Functioning Properly
Ensure the relling bottle is properly sealed without any cracks or
deformations.
Verify that the brake uid can ow freely from the relling bottle to
the master cylinder. Check for any blockages.
