Well..new tires and alignment, STILL veers violently!! HELP!

[TIMSPEED]

OK, with the new tires on and a new alignment, the car STILL veers left when braking. The guy at the shop said I needed to repalce my pitman arm, bcause it was loose. IIRC, I remember reading something where another forum member was having this sort of problem, and it turned out to be the pitman arm..I checked the brakes last night, the passenger side brake caliper ISN'T frozen, it DID work when I checked it...
