In the e"ventof the brake cross shaft assembly or rear brake rods being
dismantled, before re-assembly the shoes on each brake should be adjusted,.
as already described. Then connect the cross rods on the rear axle to the
brake balance lever.
The handbrake lever should be placed fully" off" and the brake cross
shaft turned until the projecting pad on it is against the handbrake roller.
With the croos shaft in this position the rear brake pull rods should be
adjusted by screwing on or off one or both of the fork ends, as required.
The front brake cable should be adjusted until it is almost taut.
Next ascertain that the brake pedal has about a quarter of an inch
free movement. If it has more, or less, adjustment should be made by
slackening the nuts on the brake pedal pull rod (by the side member of the
chassis frame). There should be 1/32 in. clearance between the inner nut
on this pull rod and the cross shaft trunnion pin.
The centre one of the three springs is to hold the brake rods in light
tensionand prevent rattle. .
It is strongly advised that the brake operating mechanism be adjustM
only by authorised Austin Dealers.
Reassembling.
To reassemble, replace the shocs, with their springs, in position on the
plungers. Replace the inner portion of the hub or felt housing with the
bearing and packing on the axleeasing end and push up home by tightening
the bearing nut, which must be locked by the locking washer in the same
way as before dismantling. Replace the paper joint washer on the felt
housing face, insert the key in the shaft, push the hub over the axle ,haft,
on the key, and draw it up to the felt housing by the wheel nuts on their
studs.
When the joint faces of the hub and the felt housing are together,
replace the axle nut and tighten securely up to the hub boss. Remember
to insert the split pin through the nut. Then remove the wheel nuts from
the hub, fit the brake drum, and insert and tighten the three screwdriver
.crews.
Re-lining the Brakes.
Tore-line the rear brakes it is necessary to remove the wheel and
then the brake drum by unscrewing the three screwdriver screws which
secure it to the hub; and, before the shoes can be removed for re-lining
the hub and wheel bearing must be extracted.
For this a special hub extractor is available.
For the rear wheel brakes (see illustration on page 41) remove the
axle shaft nut, haviug first taken out the split pin, and extract the outer
portion of the hub by screwing an extractor on the screwed eud and
turning the extractor bolt, which bears on the end of the axle shaft. Remove
the key from its keyway in the axle shaft.
Next remove the bearing nut, having first knocked back the tang of
the washer locking it, and prise the inner portion of the hub or felt
housing, together with felt packing and bearing, off the end of the axle
easing. Do not damage the. paper washer between the hub and the felt
housing faces, as it is important to make a good joint on re-assembling
to prevent the hub lubricant penetrating to the brake.
If the inner portion of the hub does not come off the axle easing easily,
the outer half should be refitted as closely as possible, using the wheel
nuts to draw the two halves together.
The use the hub extractor a second time, and so remove the hub
together with bearing and packing. The brake shoes can now be lifted
off the plungers and the springs detached. The old linings can be de-
tached by punching or drilling out the rivets.
The brake linings should be clamped to the shoes while the riveting
is in progress. as it is essential that they should bed down on the shoes
over their whole area. When the linings have been rivetted in position,
bevel off at each end for about t inch with a coarse file.
Front Brakes.
For the front brakes, the operation is somewhat different. Having
removed the wheel, the hub cap and the axle nut, screw on the extractor
and draw off the hub complete with brake drum. The brake shoes are
then clear for removal.
On. reassembling remember to fit a new split pin through the axle
and nut. There is a hole in the end of the hub through which the pin
can be inserted.
It is always necessary to re-line all four brake shoes on the one axle
at the same time, and before or after the re-lining it may be necessary to
slack off the brake adjustment before the brake drum can be removed or
replacM.
After re-lining the brakes, make sure that the hubs contain sufficient
lubricant, and re-adjust the brakes.
