How do you guys wire your t-brake, two step, and line lock? I'm thinking of wiring the Trans-brake and two step off the shifter knob's button, but is there any danger of accidentally hitting the t-brake during a shift down track? Is there a problem with voltage surges if the t-brake solenoid and two step are sharing the same switch? Can the line lock be on this switch also? Thanks for the help!SteveW

I dont have my line lock on the same switch. Some guys do, but I dont like to put too many "loads" on one switch. I used to run my 'brake switch off the shifter knob, but my reaction times were to inconsistant releasing the button that way. Plus I was always a bit concerned about engaging the brake in low during a pass. I now have the button mounted on a bracket about 2" off the floor, just ahead of the shifter and off to the side of it (towards the driver). I sit fairly low in the car, so it's not as akward as it may sound. With the button there, it makes my arm extended away from me, with a slight bend at the elbow. I ball up my fist, and use my thumb on the button, when I release the brake I move my entire lower arm. The year that I moved the switch in my other car, was the same year I won the championship. And I took the lead after I moved the button. (my lights were good, and they got alot more consistent) Also, with my button there, my hand is still close to the shifter for that quick 1-2 pull.

Here's what I am going to do. Keep in mind, I don't have one of them slush-boxes with the torque perverter. I am going to have the launch limiter on my shifter, and I will have the line-lock and a 3rd burn-out limiter on a on/off toggle switch, probably on my steering wheel or column. Is your handle a T-handle, or the round kind? If it is the T-kind, I wouldn't be too worried. As far as over-loading the switch with a T-brake & 2-step, if you can do it with a line lock, I don't see why you couldn't with a brake.

One T-brake wire to ground. One T-brake to 12v power. 12 v power to two step, two step to button. I have my button on the left side of the steering wheel. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member NHRA and IHRA SS/LA National Record Holder '00 & '01 Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

OK, Thanks guys, now I have a rookie question. How do you stage with the T-brake? Will the car roll slightly with the t-brake on? Do you bump in on the footbrake, then set the t-brake and hope it doesn't roll or is that not a problem? BTW it's a B&M T-handle on a pro-ratchet shifter. It's still gonna be driven on the street and since you have to engage the t-brake to shift to reverse the knob's button would be more convenient. Thanks again, SteveW

I pre stage with the foot brake, then bump in with the button Steve. The car WILL roll slightly when you release the foot brake and activate the trans brake. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member NHRA and IHRA SS/LA National Record Holder '00 & '01 Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

i hope to never need a line lock. i figure when the car gets quick enough, i'll chock the front tires when i get staged so the car wont roll, then when the light turns green, i'll just jump over the chocks when i drop the hammer, right? ------------------ 67 coupe, 650dp and rpm intake on 5.0 with afr 165 heads, 4 speed, 4.11's.....best so far is [email protected] in 1/8 mile with 1.79 60ft. time.

My car settles slightly when the brake is applied. I bump in with the footbrake, and then apply the transbrake. If I do it right, the bottom bulb flickers and gos out, and when I set the t'brake, the car settles into the beams. But I normally dont end up that shallow.My brake is a pro-tree brake also, and I still prefer the button off the shifter.

Rob,Got ya! Melissa is used to the button on the knob from her 2 step/line lock manual tranny stuff. But I understand what you're saying and she'll try both ways next season. Alex, Thanks again! Chips, Everyone,
Another question for the DIV 7 racers, Which classes allow the Trans brake? SPM but any others? And which classes during S.P.O.R.T. Wednesday night races allow t-brakes? Isn't there a 10.0-12.99 class that allows the "brake" but no t-stop or air shifter? I can't find my rule book. And, it's not on SearsPoint's website anymore. SteveW

In Melissa's case I believe that she can use a brake in "PRO/HOT BABE" class any time she wants. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member NHRA and IHRA SS/LA National Record Holder '00 & '01 Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

Carefull Alex! I'll bring you up on sexual harasement charges in front of the M&M review board! ROTFLMAO I asked this question on "bracket talk's" site and started an arguement. I guess they are not allowed in street or HS but the last few winners on HS class in Div 7 ran t-brakes! Suprise suprise Alex, Would Sara Norsworthy's ride be T-brake equipped? You remember the Stock class Mopar truck? BTW, I'm mounting the B&M cooler next to the radiator where the battery was and cut a hole in the (that peice of sheetmetal that the radiator attaches to) so it'll get air like the radiator does. Sound ok to you? Melissa says GN old man. (not really) SteveW

Sexual harrasment? For a compliment? DAMN BROTHER! Isn't she 18 yet? Around here you can use a trans brake in PRO ET with no other electronics. The truck does not have a trans brake Steve. It is not allowed in stock eliminator, only n Superstock. As long as you have the trans cooler away from the front of the radiator, that would be great. ------------------ Alex Denysenko Co-Administrator and Moderator NHRA/IHRA/SRA member NHRA and IHRA SS/LA National Record Holder '00 & '01 Fleet of FoMoCo products Moneymaker Bio US Class Nationals link

Alex,I was just kidding, you should seen Melissa grin when she read your post. It looks like they are allowed in all ET classes in Div 7. They were not allowed in H.S. & Street for the National Finals though because they aren't allowed in other divisions. Thanks everyone! SteveW
