LR3/Disco 3
A low pressure feed pipe (providing fluid supply from the brake fluid reservoir)
A high pressure pipe
The cylinder also contains a linear transducer type sensor, which provides signals to various vehicle systems, for
example, the electric park brake, engine calibration and the slip control system. For additional information, refer to
Electronic Engine Controls
(303-14C Electronic Engine Controls - 2.7L Diesel)
The pedal travel is constrained by an 'up-stop, and a 'down-stop' contained within the master cylinder.
LOW-PRESSURE PIPE
The low-pressure pipe is a plastic pipe running between the master cylinder and the common brake fluid reservoir. The
pipes function is to ensure the hydraulic system remains full. The pipes connections are of the push type and are located
at each end.
HIGH-PRESSURE PIPES
The high-pressure pipes run from the clutch master cylinder to a point adjacent to the gearbox clutch housing, on the RH
side of vehicle. The assembly consists a steel tubing and a flexible pipe. The flexible pipe is used to absorb movement
between the metal tube, which is fixed to the vehicle body, and the transmission.
A vibration absorber is fitted in the pipe. The absorber is located at the front end of the transmission tunnel on RH side of
vehicle and is fixed to a bracket on the body.
All high-pressure connections are of the 'quickfit' design utilising a 'U' shaped spring clip for retention.
CONCENTRIC SLAVE CYLINDER OUTLET ASSEMBLY
The concentric slave cylinder outlet assembly connects the external pipes with the release system contained within the
clutch housing. A securing bracket locates the assembly in the correct orientation and a seal is provided between the
assembly and the clutch housing. The bleed screw is also located at this point.
CONCENTRIC SLAVE CYLINDER
The concentric slave cylinder assembly contains the release bearing and the hydraulic slave cylinder. The assembly is
