Every mechanic knows the frustration of a spongy brake pedal or a soft clutch. Bleeding hydraulic systems properly is non-negotiable for safety and performance, but it can be a time-consuming, two-person job. This is where a reliable, one-person bleeder proves its worth, and this unit delivers.
Designed for efficiency in the workshop, this professional brake and clutch bleeder uses the readily available air pressure from a vehicle tyre. No need for a separate compressor or a second pair of hands pumping the pedal – just consistent, controlled pressure for a thorough bleed or flush.
Key Features & Workshop Benefits:
- One-Person Operation: Connect to a tyre, open the bleed nipple, and let the tool do the work. Frees up a technician for other tasks and eliminates the need to coordinate pedal pumping.
- Generous 1.5L Fluid Capacity: Crucial for modern systems. This large reservoir allows you to flush an entire brake or clutch system with a single fill, significantly reducing the risk of running the master cylinder dry and introducing air back into the lines. That means less time re-bleeding and a cleaner job.
- ABS System Compatible: With a maximum operating pressure of 30psi, this unit is safe and effective for vehicles equipped with ABS, ensuring you can service a wide range of modern vehicles without concerns over excessive pressure.

Built-in Safety & Cleanliness:
- A fluid shut-off valve prevents accidental spills, keeping your workshop floor clean and protecting vehicle paintwork from corrosive brake fluid.
- An air pressure release valve allows for safe and controlled depressurisation before disconnecting, avoiding fluid spray and potential hazards.
- Standard European Fitment: Comes fitted with a Ø45mm cap and a 90° angled connector, making it suitable for a majority of European models straight out of the box.
- Expandable Compatibility: For those vehicles requiring different reservoir caps, we stock a selection of alternative adaptors. Refer to Model No's: VS820SA, VS820UA, VS0204B, VS0204T, VS0204V4, and VS0204C to broaden your application range.
This bleeder isn't just a convenience; it's a tool that pays for itself in labour savings and consistent, high-quality work. Get the job done right, first time, every time.
