[ROVERNET - UK] P6B Sticking Handbrake

[rogerdm at iprimus.com.au]

hi Ray,

I feel sorry for you in that your rover colleagues have gone off on a conversation
about thermodynamics and drinking strange fluids and no body has sought to
fix the problem.  i know nothing of physics or drinking but I have some thoughts
on your handbrake.  

1) Is the bush that holds the two halves of the actuating mechanism lubricated
adequately and does it move freely?  Is the return spring broken?

2) Is the inner cable free to slide in the outer cable?  if the grommet is
shot then dirt may have got in and rusted it up 

3) Are the levers of the actuating mechanism free to move?

4) Are the pads binding?

I recomend you take the mechanism off, by removing the two bolts on the side
of the diff and the two pins that conect the mechansim to the callipers.
 The cable is long enough for you to bring the mechanism out from under the
car at the side for conveniant work and inspection.  You will then see the
small plate that holds the cable into the mechansim, and be able to change
the rubber grommet.  With the cable disconected you can test for free movement
of the two halves and the inner cable moving through the outer cable.  With
the mecahnsim off, its good to check the brake hose betwen the two callipers
as this is often very difficult to visually inspect.  The little felt washers
can be oiled as you re assemble the unit.  With the rear off the ground can
you turn the road wheels by hand?  If not then your callipers may be faulty.

I trust that this helps, let me know if not because I have a spare unit and
a proper manual.  Incidentally I beleive the essential desgin of the 2000
is the same as the 3500.

cheers roger
