Removing push-rod from Whitby Brake Booster

[289FIA_Cobra]

Has anyone removed the push rod (to install an adjustable one) on the Whitby brake booster?

I wanted to either re-use my old one off the Jeep MC or buy another one, but I wanted to hear how you remove it and if it's safe to do so on the Whitby booster. I don't want to damage anything internally.

TIA,

Herman

Cut it off and thread it with a die. Im pretty sure you will ruin the booster if you try to yank it out.

What's the purpose for the adjustable push rod? Not enough movement on the pedal to get the right adjustment?

The original intent of the adjustable push rod was to keep the brake pedal from coming out of the master cylinder if you hooked your foot under the brake pedal. It was possible in early cars. FFR has long since added a bar to the frame that prevents this from happening. The adjustable push rod allows you to easily adjust pedal height and helps with brake pedal feel as well. David is right if you remove the push rod from the power booster it ruins it, cutting the existing push rod, threading it and adding the end of the manual push rod is the only way I know to add adj push rod to the power brakes. This is the second time this question has come up, and both times were this week. weird. HTH

Ahh, that explains it. I have an mk3.1 and the whitby kit, and had no problem at all getting my pedals where I wanted them.

This is my pedal position fwiw.

Update: I guess I got REAL lucky. I was messing with the pedal to see how the brake switch works (I'm ordering one since I've been trying to use a pressure switch but it's never really worked out; wrong type of switch I guess) and the rod popped out. Appears that the end of the rod was only held in by a rubber/plastic piece that I could slip off with a little effort and slip it back on. It popped back in with no problem!!!

Dave: I was thinking about making my own but my last attempt on the manual MC was pretty poor (a little crooked); I already ordered one from Mark Reynolds along with the brake switch. As it stands, the brake pedal sits about 1" further BACK from the Russ Thompson pedal and I want to make it even with that pedal like I had it with my manual MC.
