too much heat=brake pedal stiff??

[NemeGuero]

alright, so refer to this post to see my set-up
http://www.zilvia.net/f/showthread.php?t=93903
since then, I have also thermal wrapped my downpipe with header wrap.
driving around for no more than 10 minutes, my brake pedal gets hard. I thought that with all the heat shielding and stuff that my brakes would be fine, but I guess not. I can feel the pressure on the rotors and my rims themselves are hot to the touch. Under the hood, I can touch the BMC and all the lines coming off it, but they aren't hot at all. the only place the lines are hot is along the firewall, but even that isnt too hot. I've seen set-ups with less heat protection than mine and they seem to run fine.. why then is this happening to mine?

please help. any ideas and suggestions will be appreciated

*I am also taking Russ's advice from the previous thread about tripling the heat shield stuff. Thanks
