Air Compressor
1. Ensure that the vehicle is turned off. 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
rangeis70 − 170psi(4.8 − 11.7bar).
6. Turn on the air control valve and activate
the air compressor to extract the old fluid.
7. Afterextraction,removethe extractor
hose, switch off the air compressor, and
turn off the air control valve.
• ALWAYS follow your vehicle manufacturer's service manual for the recommended type
and amount of transmission fluid.
• 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 ensure that the brake fluid to be added matches your vehicle’s specific
requirements 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 efficiency, malfunction, or even safety
hazards like explosions.

2. Fix the refilling bottle on the reservoir by tightening the swivel clamp clockwise.
3. Turn on the switch valve and start filling.
Note
ALWAYS keep the reservoir filled 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.

each wheel in succession.
Note
While the fluid is being changed, regularly check the level in the refilling bottle.
9. Afterbleeding,switchofftheair compressorand disconnectitfromthebrakebleeder.
Remove the bleeding hose from the inlet port. Unscrew the blue cap of the waste oil outlet
port and pour the old brake fluid from the outlet port into the waste oil barrel.
• ALWAYS wear proper PPE, such as gloves and goggles, when handling waste brake
fluid to prevent exposure to hazardous substances.
• Hazardous waste disposal regulations vary by region and require spent brake fluid to
be disposed of according to local standards.
• NEVER mix waste brake fluid with other chemicals as this may cause a dangerous
chemical reaction.
• Ensure that waste brake fluid is stored in sealed containers away from sources of
ignition and children to prevent accidents.
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 affected 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.

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 affect flow speed.
Leakage Issues
Check the tightness of hose connections to ensure there are no loose
fittings.
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 affect the bleeding
process. Ensure all brake components are in good condition.
Refilling Bottle
Not Functioning
Properly
Ensure the refilling bottle is properly sealed without any cracks or
deformations.
Verify that the brake fluid can flow freely from the refilling bottle to
the master cylinder. Check for any blockages.
