Note: New seals must be used between the
reservoir and the hydraulic unit on reassembly.
Removal
1Disconnect the battery negative lead.
2Depressurise the hydraulic system by
pumping the brake pedal at least 20 times, or
until it becomes hard.
3Disconnect the wiring multi-plugs from the
reservoir cap and remove the cap.
4Unscrew the reservoir securing screw, and
remove the securing clip, noting that the clip
also supports the clutch cable (see illustration).5Prepare a suitable container to collect the
fluid as the hydraulic unit is drained, then
remove the securing spring clip and
disconnect the low pressure fluid hose from
the pump (see illustrations). Allow the fluid to
drain out of the hose into the container. If fluid
is accidentally spilt on the paintwork, wash off
immediately with cold water.
6Pull the reservoir out of the seals on the
hydraulic unit and remove it (see illustration).
7Note the spigot locating bush on the rear
hydraulic unit inlet, which may stay in the
hydraulic unit or may come out with the
reservoir (see illustration).
Refitting
8Refitting is a reversal of removal, but use
new seals between the reservoir and the
hydraulic unit.
9On completion, bleed the complete
hydraulic system and check for leaks around
all disturbed components.Note: A new gasket must be used between
the hydraulic unit and the bulkhead on
refitting.
Removal
1Disconnect the battery negative lead.
2Depressurise the hydraulic system by
pumping the brake pedal at least 20 times, or
until it becomes hard.
3Disconnect the six multi-plugs from the
hydraulic unit. They are all different, so there
is no need to label them. When a plug has a
spring clip retainer, lift the clip before pulling
out the plug. To release the pump plug, pull
back the rubber boot and the plug sleeve (see
illustrations).
4Unbolt the earth strap from the unit.
5Prepare a suitable container to catch spilt
fluid. Mark the hydraulic pipes so that they
can be refitted in their original positions, then
disconnect them from the base of the unit.
Plug the open ends of the pipes and hydraulic
unit to prevent fluid leakage and dirt ingress. If
fluid is accidentally spilt on the paintwork,
wash off immediately with cold water.
6Working inside the vehicle, remove the
lower facia panel from the driver’s side.

Removal
1Chock the rear wheels, jack up the front of
the vehicle and support on axle stands.
Release the handbrake. Disconnect the
battery negative lead.
2Slacken the handbrake cable adjuster.
3Extract the securing circlip and pivot pin,
and detach the handbrake equaliser from the
linkage on the underbody (see illustration).
4Working inside the vehicle, remove the
handbrake lever rubber gaiter and/or the
centre console, as necessary.
5Disconnect the wiring connector from the
handbrake “on” warning switch. 6Unscrew the two handbrake lever mounting
bolts, and carefully lift the lever through the
underfloor gaiter.
7If required, the handbrake “on” warning
switch can be removed.Refitting
8Refitting is a reversal of removal, but on
completion, adjust the handbrake cable.
Removal
1Remove the clutch pedal as described in
Chapter 6.
2Extract the inboard circlip from the brake
pedal end of the pivot shaft (see illustration).3The brake pedal can now be removed from
the pedal bracket by sliding out the pivot
shaft, noting the position of any washers and
spacers which may be fitted.
4If desired, the nylon bushes can be prised
from each side of the pedal for renewal, and
the brake lamp switch removed.
Refitting
5Refitting is a reversal of removal, fitting any
washers and spacers in their original
positions. Refit the clutch pedal.
