REFITTING
Remove all dust from the drums and the linings
using brake cleaner.
Refitting is the reverse of removal.
Bleed the braking circuit (see section 38).
Adjust the linings by repeatedly pressing the
brake pedal.
Check the cut-out pressure (see section 37
"Controls").
TIGHTENING TORQUES (in daN.m)

REFITTING
Refitting is the reverse of removal. Observe the
recommended tightening torques.
Fill the circuit with oil.
Turn the wheels from left to right (engine not
running) to distribute the oil in the circuit.
Repeat the operation with the engine running
then top up the level.
If a new steering rack is being fitted, fit the track
rod ends in the position noted on removal.
To do this, slacken the bolt on the parallelism
adjustment sleeve and slacken the track rod end
while holding the axial ball joint using an open
wrench.
Make a mark or count the number of turns of
thread taken up so the parallelism can be pre-
adjusted on refitting.
Check the parallelism.
