A few minutes of cleaning after brake bleeding can prevent old fluid from remaining around the reservoir, hose and adapters. It also gives you a chance to find a loose connection or damaged seal before the kit is used again.
The maintenance instructions for the 3L Manual Brake Fluid Bleeder Kit are as follows: release the air pressure, empty the fluid container, wipe the kit with a clean, dry cloth, keep the hose and adapters clean, and store the unit in a clean, dry place.
Ensure the Tool Is Safe Before Cleaning
Once the bleeding procedure is complete, release the pressure by pressing the pressure-release valve on the side of the pump. Keep the fluid supply hose connected to the master-cylinder adapter until the pressure has been released. Disconnecting it too early could allow pressurized brake fluid to escape.
Wear eye protection and suitable gloves while handling the tool. Brake fluid should be kept away from heat and ignition sources, and children should not be allowed near the work area.
If brake fluid gets into the eyes, rinse with plenty of water and seek medical advice if it is swallowed.And any fluid spilled on vehicle paintwork should be flushed away with water immediately.
Empty and Wipe Down the Tool
After releasing the pressure, disconnect the hose and adapter. Pour the remaining brake fluid into a suitable waste-fluid container. Do not return it to the original brake-fluid bottle and do not leave it inside the bleeder reservoir during storage.
Only new brake fluid should be used for brake bleeding. Used fluid or another type of liquid may contaminate the braking system and contribute to brake failure. Waste brake fluid must be handled in accordance with local disposal requirements rather than poured onto the ground or into a drain.
Use a clean, dry, lint-free cloth to wipe the outside of the reservoir, pump, hose and adapters. Pay particular attention to the reservoir opening, hose connections and adapter sealing surfaces, where small amounts of fluid often remain.
Do not introduce an unapproved liquid into the reservoir, hose or pump mechanism. If internal cleaning becomes necessary because of contamination or incorrect fluid, ask the supplier for a procedure compatible with the kit's seals and materials.
There is also no need to dismantle the pressure gauge, pump mechanism or release valve during routine cleaning. Opening these assemblies without the correct service procedure may disturb a seal or affect the kit's ability to maintain pressure.
Inspect the Components Before Storage
With the tool empty, inspect the reservoir for cracks and look closely at the cap and hose connections. Check the hose for cuts, swelling, hardening or other visible damage. The adapter seals and O-rings should sit evenly without splitting, flattening or twisting.
Residue around an adapter may prevent it from sealing correctly on the master-cylinder reservoir. A damaged hose or worn seal may also produce pressure loss during the next job. Replace damaged parts promptly and use approved replacement components. Tape, household adhesive and unidentified sealants are not suitable repairs.
Make sure the hose and adapters are clean and dry before putting them away. Refit or store them without twisting the seals or placing heavy objects on the hose.
The tool should be stored upright in a clean, dry and childproof location. Keep it away from unrelated workshop materials and make sure the reservoir remains empty when the tool is not in use.
Before the next brake bleeding job, check that the product is in good working condition. Confirm that the hose, adapters, release valve and reservoir connections are secure. Any damaged part should be repaired or replaced before the tool is pressurized.
For normal maintenance, the process is simple: release the pressure, remove the remaining fluid, wipe the kit with a clean dry cloth, inspect the parts and store the unit empty.
