Model T Ford Forum: Forum 2014: CRAP! Now what? Rocky brake with extension is depressed when the low gear pedal is depress.

I replaced the original brake pedal on the 1912 engine with a brake pedal that had the extension welded on it for the new Rockies I just bought.

Now, when I depress the low gear pedal the linkage attached to the bottom of the low gear pedal pushes the brake pedal down.

Any suggestions?

Thank you in advance or your help.
Bob

Is your low pedal link inserted into the low pedal with the arm of the link facing outboard? If not, try turning it around to match the drawing below:

Thanks for your advice Mark. I thought of that and did a visual 'what if' I turned it around.

The probable is, the metal part that the linkage goes thru is hitting the brake. I will try turning it anyway this Saturday out of hope, just to try.

Any other suggestions, anyone?

Robert, can you take some pics of your situation and post them here? Maybe others will have suggestions after seeing your setup.

Remember, pics have to be resized to under 194K to fit on the forum.

One other thought - get on Google and search for:

"rocky mountain linkage MTFCA"

I'll bet you'll get a lot of hits on thread with pictures of other folk's setups, maybe those pics will help. :-)

Here is a really clear photo from a 2011 thread showing Dan Treace's setup (Dan, I hope you don't mind):

wow, I think mine looks a little different than that. I seems like my low and brake are closer together than Dan's. I will compare and check mine after work tonight. Thanks again.

I had a similar problem with one of mine. If your pedal is one which has the extension welded on you might need to grind out a small amount from the extension so that the clutch link will not hit it. That extension is thick enough so that it won't weaken it sufficiently to affect the brakes.

When you depress the pedals, the low pedal moves into the hogs head and the brake pedal moves out. Somewhere the two will come in contact with each other You need to remove the bendix cover and insert the link from the left side as shown in the pictures.

Here are some pictures of the link before and after I worked on mine.

That first photo with the red and gray paint is a '26, they have a bit wider pedal spacing.

Here are photos of a '19 install of Rocky Mtn brakes, using the new RM brake pedal cast with the brake tab. Have OK clearances everywhere.


ready to install new brake pedal.

But first I like to test all parts, and make the clevis fit the casting of the brake tab better, so ground the surfaces more flat, if you have interference, you can grind away on the brake tab.

Or bend the Ford low pedal clutch lever tab a bit too. Remember there are two styles of Ford low pedals, the later one '19-up has the clutch lever tab more offset to clear the Bendix cover on elec start models. Earlier low pedals have that clutch lever tab a bit more stubby and straight.



Installed and all functions OK.
