to fix your SFA Hilux's Hand Brake
here - By LeeBoy
I read "disfunctional
hand brake" and actually had to remove my brake drum to refresh
my memory as to what it looks like with all those cables, springs
and levers . Its quite simple but difficult to explain, here goes.
Just in case,
pull the hand brake up and look above the clutch lever and spray
Q20 or the likes into the slot where the HB goes through the fire
wall. The little tag that opperates the HB light sticks out of this
slot. Repeat this after an hour until you see oil seeping out from
the rubber which protects the cable(under the SFA).
Jack up a wheel
and if you look behind the brake drum(backing plate) there is a
lever with an ajustable stopper(HB cable is attached to this lever).
With the HB released, loosen the hand brake cable until the lever
stopper touchers the backing plate(this should happen on both sides).
Now on the raised wheel side through the slot at the bottom of the
backing plate adjust the self adjuster until the brake shoes are
just touching the drum(turn wheel while adjusting).
On same side
remove the wheel and drum and just below the hydraulic cylinder
there is a flat bar with a "square" spring around one
end, this is "pushed" by the HB lever which is fixed to
one brake shoe against the other brake shoe. After many years of
use this bar wears shorter which results in those levers sticking
out of the backing plate being adjusted closer to the rear spring
blade and eventually hitting the blades.The more they move out the
less leverage they have.
So , all you
have to do is remove the flat bar and weld and grind the ends (to
make it longer) .I don't know the exact length but there should
be a little play (2mm). When my HB is applied, there is a 10 mm
gap between the backing plate and lever stopper and it works like
a bomb. I hope someone will make sence of this and try it, its easy.
