Automotive brake bleeding kit designed to let one person flush and replace brake fluid quickly, ASUNCELL Car Brake Bleeder. Clear pressure gauges and a dedicated waste bottle reduce mess and give greater confidence when working on brakes. But will the adapters match your master cylinder and hold pressure reliably for repeated use?
⚡ At a Glance
- • Pressure Control: Dual gauges read 0-70 PSI and 0-5 Bar with recommended 10-15 PSI working range
- • Best for: DIY mechanics and independent garages performing routine brake fluid changes
- • Not ideal for: Vehicles without a threaded master cylinder cover of approximately 45mm inner diameter
Manual pump and 3L filling tank enable one-person brake fluid changes. A separate 1L waste bottle and hose manage used fluid for cleaner maintenance.
One-person bleeding made straightforward - with a manual pump and 3L reservoir
Manual pressure pump pressurises the 3L tank so fluid is fed into the master cylinder, while a release valve controls flow to the wheel cylinders. The 1L waste bottle collects expelled fluid through the bleed pipe and hose.
Quick, solo operation removes the need for an assistant during a full brake fluid change. The setup keeps hands drier and speeds up routine maintenance.
Consistent pressure control - with dual pressure gauges and adjustable working range
Two gauges display readings in PSI and Bar, with a recommended working pressure of 10-15 PSI (0.7-1 Bar) and a maximum working pressure of 30 PSI (2 Bar). The bleed valve lets pressure be released precisely at the wheel cylinder.
Maintaining a safe, visible pressure reduces the risk of over-pressurising the system. Accurate control helps achieve a cleaner, more reliable bleed.
Good fit for many European models - thanks to threaded adapter covers around 45mm
The kit includes a master cylinder threaded adapter cover with an inner diameter of 45.5mm and a straight adapter cover listed at 45mm, plus a black conical connector for wheel cylinder connections.
Adapters cover the common threaded master cylinder sizes found on many European cars, but checking the master cylinder head diameter before use is advised. Inclusion of multiple connectors increases compatibility for routine jobs.

❓ Frequently Asked Questions
Q: Will this fit my car's master cylinder?
A: The kit is supplied with a threaded adapter cover measuring 45.5mm inner diameter and a straight adapter cover listed at 45mm. Confirm that the master cylinder head is a threaded cover with an inner diameter of around 45mm before use.
Q: Can one person complete a full brake bleed with the kit?
A: Yes, the manual pressure pump and reservoir let a single operator add fresh fluid to the master cylinder and use the waste bottle on the wheel cylinder while operating the release valve.
Q: What pressure should be used for bleeding?
A: Dual gauges show 0-70 PSI and 0-5 Bar; the recommended working pressure is 10-15 PSI (0.7-1 Bar) with a maximum working pressure of 30 PSI (2 Bar).
🏆 Our Verdict
Suited to DIY mechanics and small workshops that work on European cars with threaded master cylinder covers. Manual pump action, clear dual gauges and multiple adapters allow controlled, one-person brake fluid changes with a dedicated waste bottle. Practical and purpose-built for routine maintenance, it delivers reliable performance and cleaner workflows for regular use.
