'30 Brake Cross Shaft
My brake pedal does not return all the way when stopped so I first disconnected all the rods from the cross shaft and removed the brackets to see if the bushings were worn. They looked fine so I reinstalled the brackets.
When I rotate the cross shaft forward by hand, as if the brakes are on, the cross shaft hits the radius rods. How much clearance should there be from the CS to the radius rods? How much travel should there be in the clevises? |

Re: '30 Brake Cross Shaft
First, try oiling the bushing on the peddle shaft. Or,You need an after market coil return spring hooked from your brake peddle to somewhere on your chassis to pull the break peddle back. Sound's mickey mouse, but it works.

Re: '30 Brake Cross Shaft
Works for me. I have one on each of my pedals clutch and brake. I made a tab that uses one of the clutch bell housing screws, both springs hook to it. Keeps the slack out and pedals back instead of bouncing around.

Re: '30 Brake Cross Shaft
If things are correct in all respects, no springs are required. The brake springs at the shoes and on the brake pull rods get the job done nicely. Curtis, most likely the front spring is weak which lowers the frame and transmission. Rear spring can do the same. Know that the radial movement of the cross shaft is slight. If the front mount is holding the nose of the engine up too far, the rear of the trans.tips down. Do a search for setting up brakes, everything has been covered in depth.

frame sag can also bind up the shaft as well.

With the pedal fully retracted as if no pressure is applied and with it up against its stop, the cross shaft arms on each side that connect to the brake rods should be pointing straight up and down. Not at an angle. Just something to check. |

Re: '30 Brake Cross Shaft
Right now all rods are disconnected. I will connect the brake pedal to the cross shaft and see if it is vertical.
