    Hi Does anyone know if I need a line lock for my Lenco drive to prevent creep on the trans brake? Pro mod, roots blown hemi application. Thanks, Trev

    yes, car will roll just like a Bruno/lenco, output shaft isn't locked like a glide brake.
    It's not creep, it's the car rolling due to nothing being held except for the input shaft in the convertor drive. Vibration, inertia, a lumpy/non-level starting line or whatever you want to blame it on can make the car roll slightly. You can easily push the car by hand when it's on the transbrake with Bruno or lencodrive.

    No line lock needed.... just rest left foot on the broke pedal when the car leaves it will toss your foot off the pedal , or you can snatch it off yourself. My dragster would roll forward from the exhaust pressure blowing backwards. I just learned to “swap feet” at the hit. Problem solved .

    It depends on if you have a foot brake or a hand brake. As Jody said if you have a foot brake then you can hold it from rolling. If you only have a hand brake then you don’t have enough hands so I line lock is needed.

    So until my 3rd arm finally develops (Thanks APG Proving grounds) I just need to keep my fat foot on the pedal until I let go of the magic button. Sweet one less thing I need to buy and wire. Thanks everyone -Trev
