Brake VENTING, "literally" Options

[aveale]

First of all, I would like to thank everyone for helping me get to where I am now!! (Engine out, longs done, engine in, fuel pump stuff, pushrod seals, valve adjustments, engine running......)

Because I messed with things (i.e. it was not broken, buy I tried to make things better and they are now worse! (IMG:http://www.914world.com/bbs2/html/emoticons/icon8.gif) (IMG:http://www.914world.com/bbs2/html/emoticons/headbang.gif) ) 3 Questions for the brake guys!

1- i have searched this site and found a good clearance is half of what the Haynes says (right now, it is at the Haynes value). Will this make a big difference?

2- my brakes need to pump up 1-2X to get effective stopping - is that acceptable (this may be related to #1)?

3- I can't seem to reduce the clearance on my rear-passenger side caliper. I have done the drivers side with no problem but on this one the allen key will spin without changing anything (this may be the cause of #2). Is this a repairable problem OR do I have to spend more $$$ on a new caliper??

Thanx
