• Centre Valve (CV) Master Cylinders
The center valve configuration helps to improve cylinder performance and seal durability with ABS.
The centre valve replaces conventional ‘cut off’ ports that can cause ‘seal heel nibble’ when used with some ABS systems.
ABS Advisory Notice When Using obp Master Cylinders
obp master cylinders use cut-off ports to ensure that pressure is relieved from the brake system when no travel is applied to the brake pedal. As the brakes are applied the piston and seal travels over this cut-off port. In normal operation the seal has travelled past this port before high pressure has built up in the system. When used in conjunction with ABS depending on how the ABS operates, pressure can be built up earlier in the travel or during the return stroke. This can then result in heel nibble where the seal is partially extruded over the cut-off port. The pulsing nature of ABS can also make this effect worse.
It is possible to run our standard Integral reservoir and remote reservoir obp Centre Valve (CV) Master Cylinders with ABS but as obp do not control the ABS we cannot guarantee successful operation.
