There's a lot going on in this photo
First you see the cable going from the Brake Bias Knob to the shaft of the spherical bearing in the brake pedal so it can be moved... base on turning it to the right or left to bias more pressure to the Front or Rear Master Cylinder.
Also you see the Throttle Pedal with a Stop on the end of the pedal and there is a stop on the back side of the Clutch pedal as well. These Stops are very much needed as you don't have time to feel for the stop on the carb or FI. or on the Clutch... just adjust the stops so the carb or F.I. go to the Stop on the Unit. or set the Clutch so the stop goes to release the Clutch at the proper amount without any over travel.
Here you'll notice that we don't have a Dead Pedal.... there just isn't enough room in a Cobra to have one .... So like the Formula Cars we put in a 2" piece of SS.. to rest our foot on and not on the Clutch pedal.
So when you get to the level of Racing I was at you will use both the Brake Bias and a Proportion Valve to adjust the brakes for weight transfer and trail braking to get around a corner as fast as you can... and it works quite well.
