As Plowman says, highly unlikely the booster has anything to do with your problem. You undoubtedly stirred up some crud in the master cyl and lines, which has made its way into the system. The bad news here is that you'll probably have to disassemble everything in order to get rid of the blockage.

I had a similar problem last year when I replaced all the flexible brake lines on my Chevelle. I got everything bled just fine except for the drivers side rear wheel cylinder. I have a power bleeder and it wouldn't pull any fluid at all out of the bleeder on that wheel cylinder. The fitting on the brake line going to that cylinder was frozen (rusted) to the line, so I had to order a new rear axle brake line kit. By the time it got here, it was too hot to work in the garage (summer time in AZ) so I just left it sit until fall. Before I tore it apart, I decided to try bleeding that one more time, and lo and behold, it worked. Evidently whatever was blocking it either dissolved or worked its way out, because it's just fine now. For once, procrastination paid off [img]<<GRAEMLIN_URL>>/biggthumpup.gif[/img]
