Abstract
A braking system comprising an anti-lock vehicle braking system for a vehicle having a pair of drive wheels (13, 14), the wheels of said pair being disposed on opposite sides of the vehicle, comprising a wheel speed sensor (17, 18) for each wheel (13, 14), a controller (19) responsive to wheel speed signals from said two wheel speed sensors (17, 18) for sensing skid conditions at said wheels (13, 14) and for generating skid control instructions, a wheel brake (23, 24) for each wheel (13, 14), responsive to fluid pressure, hereinafter referred to as brake pressure, supplied thereto, a common supply line (37), for supplying a common brake pressure for both of said brakes from a fluid pressure supply valve means (38) in accordance with a brake demand signal and a skid control means (40) controlled by said skid control instructions for modulating the common brake pressure, having a brake apply valve (51) to supply fluid under pressure to the common supply valve (39), in response to the controller detecting a wheel spin condition of one of said wheels (13, 14), to provide a common brake pressure for both of said brakes and isolating means (42, 43) to isolate the brake (23, 24) associated with the other of said wheels (13, 14) from the brake pressure.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
