5kCSTQ with FREAKY Brake Prob

["Dupree, Robert A." <rdupree@sidley.com>]

Hi All!  My 5kCSTQ since the replacement of the wheel bearings in the   
front, has had the FREAKIEST brake prob.  After having driven a short   
distance (less than 20 minutes of city), and then getting back in the car   
from the store, the brakes will not work.  Essentially I can go to Best   
Buy, get something and then after leaving the parking lot on my second or   
third brake application the pedal is LOCKED.  It's like having a brick   
under pedal.  It takes all the force I can muster, and then when they   
finally do give the car comes to a screeching stop and I look like an   
idiot. (more than normal anyway)  What is wrong with the beast?  Could it   
be crap in the fluid?  Previous to the bearings I had a new master   
cylinder put on, but they probably did not give me new fluid.  This is   
really scarry when it happens because I cannot stop the car, and I stand   
the chance of bumping someone.  Help!!
