1 Bleeding Brakes Mon Feb 21, 2011 12:20 am

My K100, 1990, with ABS, is due for a brake fluid flush. I have
gotten hold of a vacuum pump that airconditioner people use. I connected
the suction spiggot of the pump to the lid of a glass jar using a 6mm plastic tube, and with
another connection from the same lid, to go to the bleed nipples of the
ABS modulator and calipers. I've tried it on the bench and
it can fill the jar very quickly from a bottle of old brake fluid...too
much suction. I will install a valve in series with the vacuum line to
try and control the suction.
My reading so far (the recent "How to..." articles that Bert posted, great stuff!!) indicates that the
modulator/master cylinder line should be flushed first, then the RHS
front caliper and the the LHS front caliper for the front brakes. For
the rear brakes, master cylinder/modulator line and the the rear
caliper.
My understanding is that as long as the master cylinder
has fluid in it for the whole duration of the flushing (sucking) process, that no
grief will be encountered.
Are there any special traps I need to look out for, as I have not done this before?
Thanks,
Rick G.
(PS, off to Phillip Island for the SBKs and Alpine Way and Victorian Alps on Wednesday, for six day ride! Will do the flushing upon my return.)
