Master Brake Cylinder Bleeding, Again
I just purchased a new master cylinder from Paragon for my 1966 coupe. There was a tag attached to it which stated and I quote "WARNING, Due to the OEM seal design on this cylinder, you should not attempt to bench bleed prior to installation." This does not make sense to me and goes against everything I have learned. Does any body have any feedback on what is being conveyed about the master brake cylinder? Thanks in advance

I have heard that when bleeding some m/cylinder designs, that if the push rod is pushed too far during bench bleeding, the seals can being damaged.

I don't know why this keeps coming up...you CAN bleed the master cylinder in the car through the normal method. I've ALWAYS done it that way until just a few years ago.
No big deal...

Yeah - I don't remember bench bleeding being such an issue years ago. It's like it's part of some religious cerimony with installing a master cylinder these days.
