Something clogging the system, like a piece of flash stuck in the line?

Looks like JK hit the nail on the head. DOT 5 silicone won't mix with DOT 3 or 4. Get a quart of Valvoline SynPower brake fluid and flush out the master cylinder, lines and calipers.

buy a mityvac and flushing/changing/bleeding brakes is a 20 minute effort for both systems...

The mityvac is a suction device. You connect the tube to the caliper...open the master cylinder...squeeze the handle a few times to create vacuum...break the bleeder open and it "sucks" the fluid from the system. keep squeezing the handle and you can empty the reservoir, lines, calipers, everything in seconds.

If you are changing the fluid...as the reservoir runs out, start adding the new fluid...keep squeezing and adding fluid until it runs clean and clear with no bubbles...close the bleeder, top off the MC and you're done...

When we installed the SS lines on birdman's SV...we used the mityvac to completely drain his system. we removed the old lines and calipers without spilling a drop.

We even put the calipers on the compressor and blew all the sludge and "gravy" out.

Then we re-mounted the calipers...dry...and installed the new lines...dry.

Then we hooked the mityvac up and "sucked" the new fluid through the system in seconds...a few pumps of the lever/pedal...sucked some more fluid through and eliminated all the air...topped off the MC's and he was riding the bike in less than an hour from when we started...

Sounds like a great piece of equipment. When I swaped lines on my buddys ride it took us all of 3 hours to do front and rear. Most of that bleeding.

If we had spent 3 hours on birdman's brakes...we'd have spent more on the beer than I did for the mityvac...
