BRAKE FLUID RESERVOIR CONNECTION??????? 444-544

Hello all.
Can someone out there help me. i have recently received a new reservoir and connecting rubber piece.

Q1. Is there a 1cm long (rubber/plastic) sleeve that goes over the metal brake line before the rubber connector is pushed onto it. There was one there when i pulled off the old rubber connector. Was this a botch job by the last owner.

Q2. Should the protruding lip of the metal brake line come right through the smaller bore of the rubber connector tube or stay within it.

Q3. When the reservoir is held by its metal clamp(and rubbber connector fitted), there is a gap of about 1.5cm between the end of the stem of the reservoir and the protruding lip of the metal brake line. IS THIS RIGHT???

Q4. Does the top of the rubber connector have to go all the way to the top of the reservoir stem. I got the rubber connector from SWEDISH TREASURES, so i assume its the length it should be. I just feel its a little short. What should the exact length of the rubber connector be.

Q5. Finally, is there any pressure in the rubber connector when in normal operation.

Sorry to labour the points, but anything to do with brakes worries me. I really look forward to hear from you all.

Thanking you in advance.

SUNIL

    As for #5.

    If the reservoir were vented, any pressure in the line would be caused by elevation. If the material were water instead of brake fluid, elevation pressure would be .434 pounds per foot of elevation.

    For instance, a 100 foot water tower would have 43.4 pounds of pressure at its base. (water, I know)

    Since brake fluid is lighter than water, your set-up would have about a pound of pressure at the master cylinder and perhaps .15 or .2 psi at the base of the rubber connector, 4 or 5 inches below the top level of the brake fluid.

    Hello. I'll take a poke at question #1. Normally a sleeve is placed over a metal line before a rubber hose, in this case, is pushed on if the diameter of the rubber hose was too big for the metal line. This happens when, for example, you're fitting SAE type hose over a metric line. I've done this in the past for an emergency fix in order to get home. I believe the previous owner put the sleeve over the metal pipe to take up the slack for a secure fit of the rubber hose. Perhaps you could compare the diameter of the new hose to that of the one you removed.

    Regards,

    Patrick
