G - Valve


Recommended Posts

Its name comes from the fact that it has a small mass inside that will act as a pressure limiter on the action of G forces.

It was sort of a safety device to limit the pressure on the rear axle when breaking hard or going/breaking downhill.

It's a shuttle valve. if the rear brake line springs a leak, a valve is supposed to pop over and "block" the oil from the rear section, leaving you with front brakes.

vice~verca with the fronts.

Cool, thanks for the info cipx. Who would have thought that LR and G-forces would be mentioned in the same sentence :lol:

My '91 (with rear drums) doesn't have one fitted for some reason.

(I assume then, that it might help those that change from drums to disks at the rear, stopping the rear locking up as much under heavy braking.)
