Removal
1Chock the front wheels, jack up the rear of
the vehicle and support on axle stands (see
“Jacking and Vehicle Support”).
2The load apportioning valve is located on
the right-hand side of the vehicle underbody
above the axle.
3Remove the spring clip and clevis pin, and
detach the spring from the valve operating
lever (see illustration).
4Place a suitable container beneath the
valve to catch spilt fluid, then unscrew the
union nuts and disconnect the fluid pipes.
Plug the open ends of the pipes and valve to
prevent fluid leakage and dirt ingress.
5Unscrew the three securing nuts and bolts
from the valve mounting bracket, and remove
the valve assembly (see illustration).
Refitting
6Refitting is a reversal of removal, but note
that the fluid inlet pipe from the master cylindermust be connected to the lower valve port, and
the fluid outlet pipe to the rear brakes must be
connected to the upper valve port.
7On completion, bleed the rear hydraulic
circuit and check the valve adjustment.
Models before mid-April 1989
1The vehicle must be unladen, at normal
kerb weight (a full tank of petrol, but no driver
or load).
2With the vehicle standing on its roadwheels,
remove the spring clip and clevis pin, and
detach the spring from the valve operating
lever.
3Loosen the locknut on the abutment block
at the bottom of the spring (see illustration).
4Slide the spring through the grommet in the
bracket on the axle, until the correct “X”
dimension is obtained between the centre of
the spring eye and the centre of the valve
operating lever eye (see illustration).
5Hold the spring in position, slide the
abutment block against the underside of the
grommet, and tighten the locknut.
6Attach the free end of the spring to the
valve operating lever, and refit the clevis pin
and spring clip.
Models from mid-April 1989
7The procedure is as described above, but
note that the dimension “X” has been revised
to 92.0 mm (3.6 in) with the vehicle unladen at
normal kerb weight.
Removal
1To remove a flexible hose, always free it
from any mounting bracket(s) first by prising
out the U-shaped retaining clip, and then
using two close-fitting spanners to disconnect
the hose-to-rigid pipe union (see illustration).
2Once disconnected from the rigid pipe, the
flexible hose may be unscrewed from the
caliper or wheel cylinder union, as applicable.
Refitting
3When reconnecting pipe or hose fittings,
note that the seal is made at the swaged end
of the pipe, so do not continue to tighten a
union if it is tight, yet still stands proud of the
surface into which it is screwed.
