missing a friend

quite a jump in altitude from pueblo to colorado springs. about 4600 ft to 6010 ft. the brakes started tightening up again. had to pull off to the side of the interstate and loosen / re-tighten a brake line. i think the altitude change is causing the pressure in the brake lines to increase? err...? i guess...? where's my omniscient mechanic / magical flying genie midget friend - alowishus, when i need him?
