Title: Backing Plate Parking Brake Cable Holes Too Small
Post by: 69-er on March 07, 2020, 12:29:53 AM

Anybody run into this? The parking brake cables will not fit into the backing plate holes. Either the hole is too small or the cable end is too big. I wouldn't mind drilling out the hole if I knew for a fact that the hole was not the proper diameter.

Does anybody have a plate laying around that they could measure for me?

Yes, both are reproductions.

Being a retired Brake Engineer, I can tell you there would be no issue/concern with opening the hole in the backing plate just enough to allow the "nose" of the park brake cable end fitting to fit into the larger hole.  Once installed into the backing plate, and you confirm the three prongs of the end fitting expand properly to prevent them from pulling back out, you're good to go.

That's what I wound up doing.  Somebody measured two original plates for me and they measured .575".  Mine were .520".

Having to enlarging the hole wasn't a big deal to me.  What I was concerned about was that if the cable diameter was incorrect, would the rest of the cable's dimensions be correct?  If they weren't, then I'd be forced to weld up the hole to fit a correct sized cable.
