When I first started using Jim’s excellent pressure brake bleeder I often had to overcome leak issues where the cover fit on top of the master cylinder. I found that grinding a bit of a divot in the top of the aluminum cover at the rear allowed the cover to seal a bit further back and that helped. Later I found that if I removed the two hoops that hold the stock MC cover in place it was much easier to get Jim’s cover to seal since the cables pull the cover down straight instead of at an angle as they do if those hoops are still in place. I also now use a flat ratchet head 7/16 wrench to evenly tighten the 1/4 x 20 nuts that pull the cover down. Put the ratchet head side over the nuts at the rear and swing the wrench to tighten. Much easier and faster than trying to use an open end wrench in such a confined space. Snug all four nuts to make sure the cover is flat on top of the MC and then give each nut another turn to compress the rubber gasket to make a tight seal.

Thanks for pointing out a good fact, Jerry. Some of my early plates were
made of thicker material than the current ones are. The thinner plates do
not present as big a problem as the thick material. I believe that there
are some differences in the master cylinder support brace gusset that
protrudes forward and interferes with the top plate moving back. I will
address these differences in my future instruction sheets. I have a couple
of customer coaches with similar symptoms as those you describe. I'm gonna
check on their distribution valves the next time i see them. Presently
sitting at the Marina RV park in Port Towndsend, Wa. Spectacular sunrise
greets us presently. Here with Gene and Diana Ewankiw and Dwayne and Sharon
Jacobson. After a leisure breakfast, we will fire up the GMC's and head for
the rally at Port Angeles, Wa. About an hour away or so. Good times. Wish
that you and Sharon were with us.

I used mine the first time yesterday my only problem was the plate holes in
the back are narrower than the m/c
along with being right up against the support brace it was tight to get the
bolts tightened down
had no leaks the thing works great thanks Jim
girlfriends son is in town she doesnt want to come up but I might take the
motorcycle for a spin up there on sat.
