I expect the more experienced among you will know this but, I literally just put mine together yesterday. Much easier than I thought.

I had heard that you need to drop the Master Cylinder in order to press the lines in place and in fact tried that out....as it turned out the most effective aspect of this exercise was to swab a little brake fluid seals...the feed lines dropped in place with no fuss at all.

I hope this helps someone or at the very least makes you aware its not that big a deal at all. Grant

(IMG:style_emoticons/default/agree.gif) I took Eric's advice and I pull the fabric feed hoses lines loose from the reservoir when doing this task anymore.

Several years ago, I installed a new ATE M/C and I thought I felt the tubes seat, but for some reason, two years later I saw a puddle on the concrete under the M/C. The car had only been driven about 500 miles at that point, but I replaced it with another new M/C.

When inspecting the old one, I found that the inlet grommets had disintegrated into a goo. I cleaned it up and bought new grommets for it, but never figured out what cause them to deteriorate so badly in such a short time. I wondered if the tubes didn't fully seat and if brake fluid leaking caused the deterioration (IMG:style_emoticons/default/confused24.gif)

I know brake fluid is corrosive, but one would think that the grommets for a M/C were engineered to hold up to brake fluid?

I wonder if it was the "dousing" of brake fluid? My originals still looked good when I did mine last month so much that you could still read the PN.

I think if inserted correctly, they actually contact very little fluid. The downward force keeps the hard line against the washer. There is a built in O ring on the grommet shoulder should any fluid get past the face of the grommet, and lastly the "step" cut into the grommet keeps it forced down into the M/C when it fully seats in the inlet of the M/C. I am guessing that force is was causes the hard line to "click" against the washers some folks report hearing when assembling these.
