1956 Cadillac brake pedal connection question

[carguyblack]

Would anyone familiar with this car be able to tell me how the brake pedal connects to the push rod at the pedal? I tied to get the ball end to click into the receiver on the pedal but can't get it to stay in place. I can pull back on the brake pedal with my toes and lift the pedal off the push rod. Is there a retainer clip I'm missing? Is there supposed to be a rubber receiver in the brake pedal that holds the end of the rod secure? Mine just falls in and out easily and that can't be right! Thanks for any help here. Chuck Dykstra Portage, MI

Chuck,

There is a cylindrical pressure clamp (blue arrow) that slide in the “brake pedal” receiver (red arrow). This clamp has an open grove about half way, and when you slide inside the “receiver” will hold the rod (black arrow) inside.

BTW there is also a spring retainer that holds the receiver in place..!

Good luck..!

Bringing back a zombie thread

I am in need of this pressure clamp but no one seems to know what I am talking about even though I show them the broken clamp. Anyone have a part number for the numb skulls behind the counter? Maybe a source?

Thanks

The correct name for these maybe "Spiral External Retaining Rings", it would be hard for any shop to know them or even know what they are.

Been searching mcmaster for a week now with no luck. Tried both of your terms also with no luck.

Anyone know what other vehicles may have used this same retainer? 

This is the final piece before I can get the car back on the road, any help appreciated!!

Sorry I thought you meant the spiral retainer that’s what happens for not paying attention..! 

You could probably make one from steel tubing with a smaller ID than the brass receiver on the pedal bracket.

Cut the piece to allow it to expand (as shown on the picture).

Then drill a hole (same size as the pedal rod) at the center of the cylinder on the opposite side of the cut.

If you still have the old one it could give you a rough template to make one. This clamp just holds the end of the rod (ball shape) inside the hole at the brass receiver.

There could be other GM makes that may use the same arrangement, not sure which ones.

Good luck..!

Thanks, I just got back from IMS with some 7/8 OD 16ga tubing to make my own retainer. Luckily I do have the old broken one to use as a template.

Thanks for the help and suggestions!

Here is the broken retainer clip






A tube cutter provides a square piece to start with





Here are the tools needed





Two small pilot holes





On to the big 3/8 bit






Finish the slot with the hack saw and the small files then cut the relief cut in the back. Not pretty but gets the job done.





Ill take some measurements of the broken clip and post up a flat template so you can print it out if needed.


WORKING BRAKES ARE NICE!!!
