AL-KO Evo Sensabrake Actuator
The Sens-a-Brake actuator utilises stored energy (compressed air) and immediate braking is available as soon as the driver applies pressure to the brake pedal.
If drum brakes are being used, a Residual Line Pressure Valve must be installed in the hydraulic line. (Use Protex: 210R0004 (10psi))
This must be located BEFORE any split in the hydraulic line immediately after or as close as practicably to the master cylinder port.
