How to Fix Your Dune Buggy's Brake Pedal

Our old dune buggy is a lot of fun to drive. People stare and say "nice ride, man", and it makes you feel like a celebrity, well kinda. So the only bad part about driving the dune buggy is that the pin holding on the brake pedal doesn't like to stay in. So while you're driving and go to step on the brakes, the pedal just falls on the floor and you have no more brakes. That is not fun, and results in pulling the emergency brake to stop yourself.

The way the brake pedal is connected is this: there is a rod coming out of the firewall with a hole on the end. The brake pedal has a slot on the bottom with a similar hole in it. The rod comes out of the wall and fits in the slot on the brake pedal. Then there is a hardened steel pin that goes through the hole to connect them. The problem is that the pin doesn't like to stay, and is easily wiggled out, leaving you with an unattached brake pedal.

Step 2: Drill a hole

Drill a hole through the rod and into the steel pin. It is a relatively small hole. I decided on the size based on the size of the pin that I am going to put in the hole. There was no way I could get a cotter pin in there, so I basically just had to pound a screw in.

It may not come out, but I got a feeling that it willl eventually snap off. The rod pivots on that shaft to some degree and the screw will eventually stress and break. From my way back VW repair days I believs some type of circlip or other clip was used at the outer end of the shaft to hold it in place. You may want to look at another old VW for reference.
Looking at my sand rail the way the screw is set in the pin and linkage, the pin will rotate inside of the pedal assembly, which moves the point of rotation from "Linkage and Pin" to "Pin and Pedal"
