I have a 1981 Honda silverwing interstate and as I am driving and using
my brakes they are gradually sticking harder and harder.. I have
replaced the brake pads, pistons and seals and taken the master
cyclinder off and cleaned... But I still am having problems with this
happening. Any suggestions as to what might be wrong. Thank you

Do the calipers release their grip if you crack a bleeder screw?

If so, did you run a wire through the fluid return hole in the master
cylinder? It's covered by a little stamped steel piece that keeps
fluid from spraying up when the lever is released. It's a very small
hole, you need to pull off that piece, and poke a small wire through
the hole to get the congealed brake fluid out of there that is keeping
fluid pressure in the front brake lines.

This is a common problem on those bikes and is caused by the little hole
in the master cylinder being plugged. I haven't had to fix one yet but I
understand the hole is really tiny.

why did they design it that way?

what problem would be caused if the stamped piece is removed and the
fluid "sprays" inside the closed reservoiur?

You'd find out the next time you bleed the brakes Wink

Apart from that, I can (just) imagine that there can be a deeper
technical reason that would have something to do with minimising
air / fluid mixing that would be much more effective with a
small fountain in the reservoir.

Well batted, I hadn't thought of that but it makes sense.

Whenever one is tempted to remove a motorcycle part (AKA "Muntzing" [1])
because it's obviously not needed... stop, count to 20,,, count to 20
again... ...
