    Hi all,

    another new guy - hi and hello to everyone :beer:
    Need some help from you for it seems that no one over here in germany knows what to do...
    Got a 1986 Buick LeSabre Estate Wagon equipped with powermaster brakes, featuring an electrically powered hydraulic brake booster instead of a vacuum device.
    Now I'm about to bleed the brakes and replace the old fluid. Got into Haynes and Chillton's repair guides but didn't fully understand the procedure...
    That's bleeding as I know it:
    - attach a piece of tube to the bleeding screw and put it' other end into a bottle with some brake fluid in it
    - open the brake fluid reservoir
    - open the bleeding screw and push the brake pedal
    - close the bleeding screw keeping the pedal pushed
    - whilst releasing the pedal refill the brake fluid reservoir with new fluid
    - repeat this until clear, fresh fluid come's out of the tube.
    Is bleeding a powermaster really different:Do No: ? If yes - what to do???

    u might want to lay the m/c cover over the m/c reservoir , loosely , as the m/c tends to squirt brake fluid all about in the reservoir . also , start at the farthest wheel cyclinder , away from the m/c .
