I need help with brakes

Have you read the procedure in the pelican book?

Your clutch and brakes share a reservoir.... but that's it. They of course have different master cylinders, and different slave cylinders (or calipers, in the appropriate system). So these two issues should not be related. UNLESS: what brake fluid did you put in? And what brake fluid was in it before? DOT 3 and DOT 5 are NOT compatible.... and will gel in the line, causing all sorts of terrible results, including quite possibly the ones you're describing.

Not trying to horrible-ize here. Tell us more.

I have a 1999 Boxster 2.5L with manual shift. I used DOT 4. I installed the master w/o conducting a bench bleed due to ignorance. I guess I missed or skipped over that step in the 101 Projects book. Is there a graceful recovery or will this necessitate the removal of the master and then doing the bench bleed and re-install?

Hmmm... I'm sorry, I don't know. I bench bleed as a matter of course. I'm not sure you'll be able (even with a power bleeder) to get that primed / bled.
Maybe Monty can help here.
That's almost certainly the issue.

I just happen to know a "shade tree" mechanic.....

This will not make things worse and may just solve your issue. Cross your fingers hold my beer and try this......

1. Set up to bleed your brakes.

2 When ready Turn on the ignition and leave on. This will activate the ABS system

3.Go to wheel furthest from master (right rear) and open the bleeder. This should kick the ABS pump on and pump the air out through the bleeder.

4.Bleed the remaining slaves.

5. Turn your key off and use the power bleeder to bleed all brakes.

Thanks, I'll give it a try.

and speaking of slaves…

Perhaps be a good idea to bleed the clutch slave as well, according to the manual, you should keep open (under pressure) the bleeder for about 20 seconds..

I always put 'two' one liter bottles of DOT 4 on the Motive, just to minimize the possibility of getting air into the line
