92 ford probe question on brakes..
 

okay, my girlfriend has a 92 ford probe.. and her brakes are going out..basically almost out.. and she's needing to get her rear calipers replaced.
now this guy at kragen is telling her father its going to cost $400 per caliper.. i feel that shes getting majorly ripped off, what do you guys think? shouldn't it be about $150 or less?.. or am i just living in a dream world? not much of a brake guy, but i do smell a rat.
