[ST] Brake bleeding

["Lou Kallery" <lkallery@xxxxxxxxxxxxxx>]

Tony,

All the info you got from the list would probably be worth saving -- a 
virtual brake maintenance manual.

I did notice a small problem with Speed Bleeders, though, that might be 
worth mentioning.  I recently acquired an '83 Yamaha Seca 750 in Touring 
configuration.  I went through the brakes, rebuilt the master cylinder and 
the calipers -- they were notorious for collecting water -- which requires 
the dismantling of the fairing -- a time consuming process.  With all 
rebuilt and Speed Bleeders installed, I happily started down the home 
stretch to the easy job of bleeding the brakes -- but the same issues you 
speak of occurred with the Seca.  I found that if enough air were in the 
lines, it seemed as though the spring on the Speed Bleeder valve would not 
compress and the brakes remained spongy.  I refit the stock bleeders, sucked 
air through the lines until I got fluid -- even used a version of the 
minyvac.  Then I bled the lines a few times in a conventional manner.  When 
I began to get sufficient pressure at the lever, I refitted the Speed 
Bleeders and finished the job -- all went well thereafter.
