Fig. M.8 When replacing a hand brake friction pad place the lever against the inner carrier in the
position shown. Hold the locknut against the trunnion and screw in the adjuster bolt three or four
Raise the rear of the car-making certain that the front wheels are suitably blocked to prevent the car
running forward-and remove both rear wheels. The hand brake lever should be in the fully off position
whilst the adjustments are made.
Slacken the brass adjuster nut fitted to the relay lever (located beside the front universal joint on the
propeller shaft) so that the operating cable hangs loosely.
Tighten each adjuster bolt until the pads 'nip' the brake disc. Screw up the brass adjuster nut on the
relay lever until all slackness is taken up, ensuring that there is no preload on the linkage.
Set the clearance between the pads and the brake disc by unscrewing each adjuster bolt
approximately one-third of a turn. Make sure that the discs rotate freely,
M.15 REMOVING THE HAND BRAKE CABLE
Unscrew and remove the adjuster nut; withdraw the end of the cable from the lower end of the lever
and remove the spring.
Disconnect the clips securing the cable assembly to the body.
Remove the clevis pins from the levers on the wheel brake units,
Unscrew the two nuts on the axle balance lever; separate the two halves of the lever and remove the
cable and trunnion.
M.16 REMOVING A BRAKE DISC
Remove the brake unit as detailed in Section M.7 and withdraw the hub by the method described in
Section K.6 (front) or Section H.2 (rear).
The rear disc is separated from the hub by removing the four securing nuts and washers. The front
disc is secured to the hub by four set bolts with spring washers, and after removing these the two
components may be separated.
M.17 REPLACING A BRAKE DISC
Assemble the brake disc to the hub by a reversal of the instructions given in Section M.16 and fit the
assembly to the vehicle.
Check the disc for true rotation by clamping a dial indicator to a suitable fixed point on the vehicle with
the needle pad bearing on the face of the disc. Run-out must not exceed .006 in. (.152 mm.), and in
the event of the value being exceeded the components should be examined for damage and, if
necessary, renewed.
