I wanted to discuss a minor difference between a older style master cylinder (probably original) off my 1997 Pribbs M101A3 trailer.
First, a side-by-side comparison. The new one is (obviously) the shiny silver, which is the "marine" (wet environment) finish:
Part Number: 10614-M

For reference, the original master cylinder used this vented cap with the 'U' shaped pipe and coolant hose:
As can be seen in the third picture, the new master cylinder has a wider opening, 1-5/8" to be exact, comes with a different square topped vented cap, and uses a rubber gasket instead of a copper crush ring. I do see that Croft also sells an alternate, tall, rounded top vented cap, for an additional (at the time of this writing) $60. What is the benefit, if any, of this cap?
