Bleed your brakes on your own. A pressure bleeder cap that screws straight onto BM series brake master reservoirs.
- 75mm x 3mm thread
- Schrader valve for air or a pressure bleeder
- Suits BM44, BM50 and BM57 brake masters, including HFM
- Keep air pressure at 10 psi or less
The cap replaces your reservoir lid while you bleed the brakes, so one person can do the job. It has a Schrader valve you can use two ways:
- Compressed air: pressurise the reservoir through the valve. Don’t go over 10 psi.
- Pressure bleeder: remove the valve insert and connect the hose from a pressure unit filled with fluid.
With the system under pressure, open each bleeder in sequence until no air is left in the system.
