REFLECTOR: Brake performance

[Al Gietzen]

When I initially filled the fluid in my RG I put the gear about half way up,
and put the fluid in from the bleed nipple at the bottom.  Added fluid until
the reservoirs were 2/3 full.  No further bleeding required. The brakes have
worked fine except for some chatter early on.  Turning the rotors solved
that problem.

 

BTW; a poor-man's tool for back filling fluid is a 1 quart plastic oil (or
other fluid) bottle.  I drilled a hole in the cap and threaded in a nylaflow
fitting that came with the kit.  A length of nylaflow, and a piece of vacuum
line or gas line, and you're set.  Clean the bottle and the DOT 5 fluid.
Connect to the bleeder, hold the bottle upside down, and squeeze. Photo
attached.

 

Jim,obviously this works for RG's as well, but is there an easier process
for RG's?

IT IS ALMOST IMPOSIBLE TO GET ALL OF THE AIR OUT of Matco brakes.

 

See the following for a diagram of the calipers and pay attention to the
position of the blead holes.  On a fixed gear you may have to remove the
caliper assembly and turn it in many directions to rid yourself of air.

I am having trouble with air in my brake lines - actually only on one side.
I have bled the brakes multiple times on that one side - from the bottom
until no bubbles occur and the brakes are firm.  It take no time for the
brakes to need pumping again on that side.  I have even bled the brakes,
flew for an hour or so, and had no brakes on that side when I landed.  It
wasn't pretty..

 

Do I have a Master Cylinder problem or a connection problem?  Bubbles are in
the nylaflow lines near the brakes but no fluids are on the floor.  Do I
need to install the new Cleveland assembly to cure this?  Thanks, JT
