VCCA Home Forums TECHNICAL - 1945 AND EARLIER 1929-1932 Pedal Stop

I was trying to raise the brake pedal by adjusting the Pedal Stop. It doesn't raise it. Maybe I was trying to adjust the wrong rod. Has anyone had any experience with this ?

I have a picture of the brake pedal stop attached.
Also, new brake shoes have been installed and grab on the fronts and the rears don't even seem to help. This may be further adjustments.

Any assistance is appreciated. Thank you.

With new shoes I would go back to step one and go through the whole process. Random adjustments here and there will not do the job.

Do you have the manual or service steps for adjusting after relining? The pedal is adjusted after all wheels and the cross shaft are adjusted. The picture above does not like like the one in my manual-Mine only shows one rod connected to the pedal and that's the one adjusted after the wheels and cross shaft.

Hi Steve,
Page 110 of the Chevrolet Repair Manual shows the two two rods. I was interested in what does the brake cross shaft brace do (B on the Fig. 100) I thought it had to do with the pedal height. Apparently not.
I have adjusted the brakes as noted in the manual, but now the fronts seriously grab. Looks like I will have to start all over again.

The brake PEDAL STOP and the clutch PEDAL STOP are same. You can see on page 60 Fig. 58. and on the front of the bottom rod on Your attached image.
First You have to adjust the stop so that the clutch pedal stands about 1/2" away from the floor board. See page 58 Clutch Adjustment.

Peter I found the diagram you referenced and see it is for the 1-1/2 ton trucks. If that is what you have I am not sure of the process though it appears to be somewhat the same as the passenger cars. Perhaps one of the members with a 1-1/2 ton will chime in.

Hi Steve, I have a 31 Sedan and the photo is the same as on my car. Sedans and 1/2 ton trucks have the same linkage.

That's interesting Peter as both of my Chevy manuals and a Raybestos one show only one rod in their diagrams . My Chevy manual is dated January 1932 so I guess they changed that year.

The 1931 brake system used a support rod bolted to the gearbox side to stop the centre cross shaft flexing under braking pressure. that is what is shown in the diagram as the second brake rod. 1932 used a smaller pressed steel bracket bolted to the new rear gearbox cross member. the brake pedals in both years only has the one operating rod.
