Master cylinder height

I thought that when mounting my master cylinder I had to have it so the level in the reservoir was higher than the calipers in order to maintain a head of pressure, but on looking through some pictures I see that some have it just above the floor pan height, an MK chassis it was. Am I wrong then?

Sorted. Thought it might cause air traps if it were lower. Cheers

It is a commonly misunderstood thing. Gravity doesn't affect the braking system and it works solely on hydraulic pressure.

Yes but air naturally heads for the highest point in the system, it can escape through the master cylinder but it cannot escape elsewhere so gives grief when bleeding particularly if the high point ends up being the top of the diff on a solid axle!

Having the reservoir mountedhigh has an advantage in that a very slight positive head helps keep the rubber seals expanded and pushed into good contact against the cylinder bores.
