Does anyone have any tips on how to adjust AC brake setup with Rich Baughman linkage arrangement. I am having a few problems with the brake pedal returning back to its correct position. Stops great but, I have to pull the brake pedal back to original position as it does not return on its own.
Try installing a spring on the pedal to pull it back. Do you have the springs on the brake arms that keep them pulled back?
Mark, there is a return rod with a small spring. The return rod passes through this spring. There was no large spring like those used on my repo Rocky mountain brakes.
Go down to 10:58
I do not understand what you mean by return rod passes through this spring? Do you mean the push rod between the pedal and his cross shaft? I would still suggest adding a heavier spring between the rod and cross shaft to pull the pedal back.
Can you post a photo.
It happens that I'm currently making a pedal for some AC brakes. I still have to get the brakes from Larry, but I already have Rich Baughman's linkage.
This picture from the instructions shows the brake control rod attached to the pedal above the shaft, and the push back rod below the shaft.
This is the push back rod. The thin wire is just to hold it together until it's installed. As you see, the rod is spring loaded and fits into a tube. The tag says the tube can be shortened if necessary.
The linkage comes with installation instructions. If you don't have them, contact rich.
Eventually I'll be able to get pictures of the whole set-up, but it won't be right away. I'm making the pedal now so it can be included in the hogshead overhaul that's part of the engine/transmission rebuilding. The time estimate: snow won't be flying yet, but it will be close. That's for the engine/transmission. The brakes will come after that.
Ok now I see! No comment and I will leave it at that.
Here is the link to a post a few months ago in which I included a more detailed list of key tips when installing the brakes with the Baughman linkage. http://www.mtfca.com/discus/messages/599638/623576.html
If you scroll down the post to 09:33 am you will see the detailed instructions. I also included pictures of my setup. If you did not ream the holes a bit in the linkages it is possible that the pedal is sticking due to that. The return rod with spring should push the pedal all the way up. If it doesn't then check carefully for drag somewhere in the system. Hope this may help.
Thanks, Mark, Steve, and Bill. Bill that is great advice and I wish I would have read that before I started installing. I did find many of fittings very tight I did some grinding and reaming but probably not enough. I will go back over what I have installed and also grind off the very top unused arm on the brake because it does interfere with floor boards. I did modify floor boards to reduce this interference but still not enough.
