[DeTomaso] Nudge: Pedal Stop Bracket on an early '71

Thanks Jeff, I did notice a slight (about 1/2 inch) difference between my
clutch and brake pedals with the brake being a wee bit higher than the
clutch. With it adjusted the way it is right now, that 1/2 inch depressed
would start to engage the brakes which would make me need to readjust the
plunger from the booster. Not a big deal, but I don't want to do it if I
don't have to.
Will the pedals drop significantly as the brakes wear? Still looking for
a down side mechanically. The pedal feels right as it is now but it's
still all fresh..

Thanks Jeff, A I did notice a slight (about 1/2 inch) difference
between my clutch and brake pedals with the brake being a wee bit
higher than the clutch. With it adjusted the way it is right now, that
1/2 inch depressed would start to engage the brakes which would make me
need to readjust the plunger from the booster.A Not a big deal, but I
don't want to do it if I don't have to.
Will the pedals drop significantly as the brakes wear? A Still looking
for a down side mechanically.A The pedal feels right as it is now but
it's still all fresh..

A The other purpose is to make sure the brake pedal and the clutch
pedal up-stops are at the same height.
Since there are supposed to be pull-up springs on both pedals, (the
hair-springs which always seem to be broken) something must be used to
restrict the pedals upward travel.A Due to their different mechanisms,
the amount of slack will be different and can result in different
heights when no pressure is on the pedal.
The clutch pedal should pull hard against the snap-ring retained
pushrod in the clutch master cylinder, but I think the booster
mechanism is different and needs the additional stop point to manage
the play.A
Others may have different ideas.

Somebody must know the factory purpose of this brake pedal stop
bracket.
Anybody?
