Anyone ever rigged up a 2 step switch to run off your brake pedal?

A racing friend mentioned that since I footbrake maybe I should try it. My opinion is it would be hard to let off the brake exactly the same every time.
 
I’ve heard of them being switched by the clutch pedal before. I guess it depends on if your bracket class allows that in foot brake racing. You’d probably need it set at the bottom of brake pedal travel and maybe add in a return spring to have it disconnect consistently.
 
1 thing to consider is, anytime you hit the brake pedal the switch will be actived

I was going to contact the manufacturer and see what happens if the 2 step is activated while you are above the limit. Also, bad news from a favorite track that has a footbrake class. They don't allow two steps.

You could always wire two switches - one at the brake and one WOT microswitch at the carb. Both would have to be depressed for the 2-step to activate. I was mulling that over for my build. I'll be curious what you end up going with. Please keep us posted.

Edit - just saw your track doesn't allow 2-steps. That's shitty.

You could just mount (dash, switch panel, wherever) an inline rocker switch (between the pedal switch and 2 step) that you can turn off when not wanted. It would just break or make the circuit...you'd of course be kicking yourself every so often when you forgot to close the switch before getting to the line. I see that 2 steps aren't allowed in your one class, but maybe you compete in others?
 
Many of us in Stock run a pressure switch in Brake line rather than the
switch on the brake that we used to run years ago.

I would appreciate it if you would point me in the right direction for one of these switches.
Also what's to keep the 2 step from coming back on down the track when you apply the brakes?

I instructed a member here how to wire a 2 step into his horn with a toggle switch.
Toggle one way was the horn, and the other way was the 2 step using the horn on the steering wheel.
 
Another alternative is to mount a momentary switch on the side of the brake pedal. Put it in a position where you can activate it at the line with your foot (while on the brake) and just push on a different spot on the pedal after the stripe.
 
The activation pressures is higher than I would ever press the brake
petals to slow the car down. Lots of pressures switches that would work
on E bay.

Interesting. Sounds like something for a street/strip car that still has a horn ring.

At least it's not my home track. It's one I go to about 3 times a year.
 
Possible if it has a high side activation and a low side both side adjustable
settings. Try Biondo web site to see them.


Start with 800/900 on the high side and 250/300 on the
low side and experiment from there. Even the top and
 
The way I did my clutch switch was with two 4 prong relays activated off the line lock momentary button and a toggle switch. Use the line lock button to heat the tires, then turn on the toggle switch for power to the second relay, that goes to a micro switch on the clutch pedal( your case the brake pedal), which is activated threw the first relay for the line lock. Once the clutch or brake pedal is released you have to press the line lock button to reactivate the clutch or brake pedal micro switch.

If you have a brake pressure gauge you can stage it at the same brake pressure each time.

I've heard of people doing that. The issue isn't brake pressure but engine rpm.

If you use the two step off off your brake light switch. The rpm will be the same and the brake pedal travel will be the same if you stage it t
at the same brake pressure.
