Below is a picture of the
new booster spacer bolted up to the pedalbox. The picture is slightly out
of focus but you can still see the new pushrod that I have made up. At
the booster end I drilled a 3mm hole to accept a drivepin to ensure the
new pushrod remains in alignment with the pushrod going into the booster.
At the brakepedal end the standard Niva pin and locking washer were retained.
As mentioned on the previous page
I thought about fitting some kind of reinforcing strap to this whole assembly
to support and strengthen it a bit. Without the pedalbox in the car the
firewall in a Niva is very flimsy and flexes a lot. Even with the pedalbox
bolted up there is probably quite a bit of movement in the firewall when
the brake pedal is pushed hard. I know that in race/rally cars it is common
to fit a strap to the booster or mastercylinder to give the brake pedal
a more positive feel. If it is good enough in those cars then it must be
good enough for my Niva I reckon. So this is what I cooked up.
This is suprisingly effective at
stiffening everything up. There is no movement whatsoever in the booster
with this bracket in place and bolted up.
While I was in the mood for fabricating
things I also made the spacerplate that is needed to space the power steeringbox
of the chassis rail. This was made out of 12mm mild steel plate. I had
to incorporate new stops to limit the lock on the steering before the mechanism
in the steering box itself ran out of travel. In a standard Niva the steeringarm
stops on the mountingbolts but due to the Toyota box being a bit longer
than the Niva box this was no longer possible.
