| | | | Joined: Feb 2008 Posts: 9 Apprentice | | Apprentice Joined: Feb 2008 Posts: 9 | I've put a new (original style) master cylinder in my '41 1/2-ton canopy, but I was missing the original clevis/plunger. Made a new one from a (gasp!) Ford part. I note in my parts catalog that the right part seems to have a locking ring to hold the plunger in place (and also, apparently, to limit return travel on the pedal). Am I reading this right, and does this explain why I'm having such a hard time bleeding the brakes? And, if so, any suggestions on where to find a plunger and related locking parts? Thanks.

My unprofessional take on this! If the piston is the proper one for the master cylinder, and your Ford piece has the same physical dimensions as the original Chevrolet rod, it should work perfectly.
I think for the master cylinder to function properly, the piston need to retract fully. If your makeshift part allows this to happen, your bleeding problems are elsewhere.
Mixing and matching brake parts would be the ultimate NO-NO, but it sounds like your Ford items are only linkage related.
Bleeding can be tough sometimes, so it is probably a procedural problem as opposed to a mechanical problem...we hope.
I'll bet someone will pop in soon with more specific info and maybe even a lead on a replacement Chevrolet part.

They say money can't buy happiness. It can buy old Chevy trucks though.

This step can be forgotten sometimes.
