Master cylinder angle



Master cylinder angle

Postby chromebumpers » October 17th, 2013, 11:14 am

I searched but I cannot find anything. Last time I was at Mecums there were a lot of restored cars and trucks that had brake master cylinders mounted on very steep angles, one or two looked as if it could be over 35 degrees. Those that I noticed had power brakes.

How can you have full a volume of brake fluid in the front (larger) reservoir with such an angle? I don't remember seeing this in a factory original setup. What would the need be? If you need a photo let me know.

CLEAR DETAILED photos are ALWAYS useful,
but I,m a bit confused with the question, are you intentionally trying too mount a master cylinder at some particular angle or trying to prevent it being mounted at some particular angle and what is you concern or reason?
yes Id agree that mounting a master cylinder at a fairly steep angle will in some cases reduce the reservoir volume of brake fluid available , but I don,t think its critical to the actual function in most cases.

I've seen these BMC mounted at acute angles for years and many times asked the owners why, the answer usually - "I got it that way" or just straight out "never noticed." My recent Chevelle purchase which I sold while still in TX had such BMC. The buyer lifted the wire bale and pulled the cap - it made a mess with the fluid and I had to scramble to flush the area and dry. My question is for the next time - what's the reason for the exaggerated angle and it seems as if 1/3 of the fluid capacity is lost, it must have some effect otherwise why have a "Min" fill line?
