ABSTRACT:
A brake pressure failure warning system for use with a split or dual type braking system having two brake lines, includes a stepped piston associated with an electrical warning switch and supplied with brake pressure from both of the brake lines, a proportioning valve disposed within the rear wheel brake line, and three fluid chambers each fluidically connected with the stepped piston or the proportioning valve. When either one of the three fluid chambers is subjected to a hydraulic failure, the stepped piston is axially moved so as to actuate the warning switch.
