Bleeding FC calipers
Hi.
First off, I know I dont belong here since my heart beats and doesnt rotate. Hopefully I will get there some day.
Anyways I mounted rear calipers from a FC on my MX3 and cant seem to bleed them propperly, and I was wondering about the two bleeding valves. Do I need to bleed them in a spesific order?
Tried the search and FAQ but came up short.

"Speedbleeders" are an excellent way to quickly and accurately bleed your brakes. They have a one-way valve that enables you to do them by yourself. Search "speedbleeders" to get a link.

I recall reading that unless you disassemble the caliper, you do not need to bleed through the top valve. However, I always do the top valve first anyway, and then the bottom. [Air rises, so that has some logic to it.
] BTW, I checked the factory service manual and it does not specify whether or not both need to be bled, but I could have missed it. The manual does indicate that the sequence of bleeding is the wheel furthest from the master cylinder to the wheel nearest to the MS.

As I recall, the top bleeder screw is tapped into the top of the caliper piston volume. So I suppose that any air in that volume may not be released by bleeding through the bottom bleeder screw since any air would tend to remain at the high point in the system.

It almost always takes me two attempts to bleed FC calipers. The 4 piston fronts trap air everywhere, and the rears just seem to take two bleedings. Bleed it once, then drive around for a few days to shake any air bubbles to the top, then bleed again. That's generally what I do.
