    on, you can't build line pressure with the cap off.

    Huh? /forums/images/graemlins/confused.gif

    The resevior isn't pressurized /forums/images/graemlins/rolleyes.gif

    I would leave the cap on, un-latched, just to keep brake fluid from squirting over everything. And you have to keep checking/adding fluid so you don't suck air /forums/images/graemlins/thinking.gif

    I always leave the cap off, and hood up, this way some one can watch the level as they pump the brakes, as long as you act sane there will be no spill issues /forums/images/graemlins/deal.gif

    I've always done it with the cap off so I can watch the level and add more if needed.

    The lid doesn't matter... what matters is if there is fluid over the bottom of the reservor so it doesn't suck air.

    I just did this last week, I had the cap off and it squirted fluid all over the booster so I just placed it on there loosely and kept checking the fluid level....worked fine.
     
  9. I agree. Cap off, just press brake pedal slow and it wont squirt all over.

    I've always bled brakes with the cap off....and never had any spilling or squirting issues. It works for me! /forums/images/graemlins/thumb.gif /forums/images/graemlins/thumb.gif
