Hand Brake Adjustment
To adjust the hand/parking/emergency brake:
1) With rear axle on jack-stands and brake off, remove wheels
and replace at least 3 wheel nuts equally spaced (with spacers if
necessary) to hold drum/rotor assemblies in their working
position.
2) Check to see that the stop screws at the ends of the cables
at the wheels are in contact with the brake backing plate. If they
are not, de-adjust the brake lever inside the cabin until they
are. The locknuts at lever can be difficult to get at.
3) Rotate drum/rotor to allow access through hole in face of
drum to adjusting wheel of shoes. Adjust shoes until they are
obviously binding. While adjusting, occasionally work the brake by
stretching cable by hand to ensure shoes remain central to drum.
Note: Binding can be difficult to feel with LSD, viscous
drive and/or auto. Experience counts a lot here. These three items
cause resistance to turning drum/rotor and reduce your chance of
feeling shoes starting to bind. If you want to be anal, remove the
rear axles to alleviate this problem.
4) After binding is felt, back adjuster off 3-4 clicks. If you
don't trust yourself, make it 5-6.
Note: The factory manual recommends backing off 8 clicks.
The factory method works, but if you follow it, you may find that
the in cabin lever adjustment (see point 6) will pull the stop
screws away from the backing plate. The danger with this is that
should the cables become at all sticky, and not return to centre,
one brake may be kept slightly on. CRITICAL in adjustment is the
starting point i.e. stop screws on backing plate (point 2).
5) Rotate drum/rotor to ascertain that shoes have clearance.
6) When totally sure that all is in order with cables and
drums, adjust lever inside to come tight at 7 clicks.
7) Work brake a few times and recheck that shoes still have
clearance. Tighten lock nuts at in cabin lever. Oh, and don't
forget to put the wheels back on.
8) Have one or three #6.
Special note!: A mal-adjusted hand/parking/emergency brake
will act in one of two ways. Too loose and it will not be
efficient (able to live with that). Too tight and it will build up
heat and bind at the most inconvenient place and time (not so easy
to live with). |
