Title: '93 K1100 rear master Cyl Cap needed
Post by: KCinSB on May 28, 2012, 10:27:45 PM

I have been trying to pressure bleed the brakes on my '93 K1100, which I did before with some success....  anyhow, the rear brake reservoir cap I have is a monkey work cap from auto parts, that fits the reservoir, but also has a vent path right through the threaded part.........  not so good!!  We tried to plug that leak sorce with J-B weld, but it still leaks all over the place while trying to get the job done.  I need a cap that will fit a K1100 rear brake reservoir to add a fitting and make a decent bleeder cap.  Of course BMW wants a million bucks for a replacement cap.  Has anyone found something to use for this purpose ??  You never know...........  it's possible..............    :yes   KC
