brake lights stay on!!!

ok here is the problem. after i swapped in the 1ton axles my stock master didn't like the brakes too well so i swapped in a hydro-boost setup from the same truck i got my frontend from. well now my brakes work great but my brake pedal doesn't raise up enough to let off on the brake light switch. what can i do? when i installed the hydro-boost setup everything seemed to be/fit fine. right now i have a bungy cord hooked to the pedal lever and it runs up and over my steering column and hooks to my tilt lever but i'd like to loose it if possible. any ideas?thanks

it's one ton o' fun!

1. The bellcrank throw ain't long enough.
2. Make it adjustable.
3. Remove the MC.
4. Remove the Bellcrank.
5. Do this yourself or have a machinest do it... drill out the center of the bell crank and thread it.
6. Insert a nice little bolt into the threads.
7. Re-install the MC.
8. Adjust the bolt to increase the throw and decrease the pedal slop.
9. When adjusted remove the MC.
10. Use thread lock to keep the bolt in place.
11. Re-assemble the MC.
12. You're done.

Re: brake lights stay on!!!

Can you just bend the tab on the pedal where it contacts the brake light switch? I had to do this after my booster upgrade. My setup only required about 1/4" adjustment. The tab is easy to bend. If the pedal is lower than you like it then you will have to adjust the actuator rod coming from the hydroboost. This may require cutting the eyelet off and lengthening the rod. If you like where the pedal is then I would relocate the brake light switch to accomodate the current pedal height if bending the tab won't work.
