Re: '88 80Q Bleeder Screw Broken

Hi Michael;

    You will have to try to extract and replace the broken bleeder screw
eventually, but you can do the master cylinder job and bleed that line at
the caliper's flex hose connection. The caliper should be full of fluid with
no air and it isn't really necessary to bleed the caliper. Pressurize the
system and crack open the connection between the hard line and the flex
hose. Let the fluid bleed out until air-free and retighten the connection.
I've used this technique to good effect a few times when I've had trouble
with bleeder screws.
