22 Brake pedal

[jwrightjr]

Oh the things you find while looking at other things! Remember I'm a T-novice so please be kind if I am asking a stupid question. I was watching a video somewhere and noticed that when the handbrake lever was pulled back the forward pedal moved as did the brake pedal. I could not remember my brake pedal applying itself when the handbrake was pulled so I went and checked it out. I was correct it does not move so I pulled up the floor to see what was going on.

I noticed a witness mark that looks like the shaft is sneaking out. Could this have anything to do with the brake not moving with the handbrake lever? The shackle connected to the forward pedal looks like it is canted and not inline suggesting the shaft is protruding? The brakes do go to the floor but stop the car (not well mind you). Until Bill took me for a ride in his 26 last weekend I had never been in another T. He showed me how they are supposed to operate which motivated me to look at some of the things I think mine is lacking. I do have the manuals for the car, owner and service. I plan on looking through some of that tonight but thought I would pose it to the gurus and see if I am looking in the right area. Thanks in advance for any guidance.

Foot brake has NOTHING to do with the parking brake. Neither moves the other. That clutch arm has a spring added to pull it out ward. Doesnt belong. It there as a patch to stay above the parking brake cam. That shaft floats in position. Something is worn or misaligned with the cam & arm contact bolt.
Why dont I see a parking brake lever?

John, you don't see a parking brake lever because you are not looking carefully enough! The bake rod is visible hooked up to the lever. The lever s partially shown on the extreme left.

The clutch linkage cannot be square on all the time. Because the pedal moves sideways on the ramps, it needs to be able to cant a little off centre. That is normal. The spring from the clutch fork to the frame is not normal. If the bolt does not ride on the ramp as it should, it is relatively easy to bend the arm on the fork to correct the alignment.

Hope this helps,

I’m confused here is the link to the video I was referring to showing the brake moving with the clutch pedal. Shows it at about 38 seconds in.

I have not taken the cover off the transmission yet to look at it but that shaft sticking out just doesn’t look right to me.

The brake pedal moves because the owner has auxilliary brakes like modern Rocky Mountain brakes and they are either improperly adjusted or he is not using a slider on his equalizer.

Not to worry.

The handbrake lever is there out of view on the far left.

What is more concerning is it seems the speed lever cam on the cross shaft is bent over missing the full surface. That could be the reason for that lateral spring, to pull the clutch lever shaft over to maybe get a ride on what's left?

John, on that video link you posted, I don't blame the person driving but the clown who taught him, use the engine as a brake when slowing down keep the left foot off the high-low pedal until nearly ready to stop for a neutral or the hand brake 1/2 way until one is comfortable with the left foot, Trying to use low to slow the car down will wear or break things.

My bad. I see it now.

One thing which might help in your situation, would be to insert the adjustment bolt with the head down. That would widen the contact with the cam. Also sometimes the cam gets bent and needs to be straightened.

I appreciate everyone's help. I removed the spring and the cam lever does just float around. Seems like there should be something retaining it on the inside but have not got that far yet. Pushing it in does line everything up the way I thought it should be except the bolt is off to the inside and not centered. I think turning the bolt over would give it a little more surface area but I don't think it can move over any further than it is. Nevertheless I will turn it over. I have not removed the cover yet to see what is supposed to be holding it, maybe nothing? Just seems like from the shiny spot on the cam it spent most of it's life inside the housing. Other than trying to center the cam and bolt anyone see a reason why that spring would be there?

Under the cover there is a throw out bearing. (looks like a double pulley) The back grove has a brass C shaped piece that pulls back on the (pulley) Attached on either side is an arm attached to the clutch shaft. There is a small amount of side play around that brass C piece. Any extra wear or loose arm rivets add to the side play. That may be why a spring was added. It is not normally needed & in fact, can cause more wear in the brass piece. Look in your manual for a view of the parts.

It is a simple matter to bend the forging with the bolt out towards the ramp a bit. One crescent wrench across the arm, another across the first wrench to work as the turning lever. Inserting the bolt head down will help, providing a wider contact on the cam.
