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

[jgkrenton at comcast.net]

Rob: 

My late 71 mfg (sharp cornered bumpers 72 model year) has the same bracket. This is a wild guess but I think it serves two purposes, one is to eliminate the slack between the pedal and the mechanism in booster, there is a little. (and I believe the booster rod might come out if you pull hard enough, it's been a while since I had mine out.) 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. 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. 

Others may have different ideas.

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

Anybody?
