INSPECTION

SECTION – Examine fit of pedal on shaft, and if excessive slack is evident, the bearing
252 should be replaced.

– Assemble pedal on shaft and take up any end float by fitting packing
washers between the side of the pedal bearing and the shaft bracket.

– Examine fit of thrust rod jaws in tube. These are a press fit in the tube
and there should be no movement.

TO REPLACE

SECTION Reverse operations given for removal, ( Section 251 ).

FOOT BRAKE CROSS SHAFT — TO REMOVE
( See Figure 9 )

SECTION – Disconnect front and rear brake cable connections from the compensating
254 levers ‘A’. Disconnect the footbrake thrust rod from the cross shaft
lever. Remove the castellated nut and dished washer holding each cross
shaft bearing in the brackets on the cross member. Slacken the bolt ‘G’
clamping each bracket to the cross member. The cross shaft can then be
turned round the member into a convenient position for removal.

INSPECTION
( See Figure 8 )

SECTION The arms ‘F’ on which the compensating levers swing are keyed and clamped
255 on to the small tube ‘E’ of the cross shaft, and to each clamping bolt is fitted
the compensating lever stop. If the stops have become bent due to faulty
adjustment of the brakes, in which condition the compensating lever stops are
subjected to excessive strain, they should be removed and straightened. The
operating lever, ‘C’ is clamped and keyed to the larger tube ‘D’ of the cross
shaft, and to the clamping bolt is fitted a stop which should come in contact
with the cross member when the foot brake pedal is in the off position, and
so prevent the pedal coming back too far. The tubes ‘D’ and ‘E’ are pinned
together in the centre by a piece of steel tube belled out at either end by a steel
ball and there should be no movement between the pin and either tube.

TO REPLACE

SECTION Reverse operations given for removal ( Section 254 ) .
256 It is essential that the cross shaft bearing brackets on the cross member are in

correct alignment so that the cross shaft is quite free to rotate in its bearings.
The brackets must also be set on the cross member, so that the top of the rear
brake cable jaws, ( ‘F’, Fig. 9 ), when connected to the compensating levers,
are horizontal and level with the top of the frame ( Section 263 ).

– Finally, adjust brakes as detailed in ( Section 263 ).
