Please god tell me you will never take ANYTHING to sears, jiffylube, midas or walmart to get a repair done. Their motto is, "Let us screw up your car and kill innocent people". First of all, the soft pedal is probably a result of air in the lines. They COULD have fixed that if they knew jack. The extra washer bit... a lie. The dumbass probably left the line loose.

My advice. Stop right now, find a competent mechanic and pay whatever they ask. If you can't do it yourself, its worth whatever they charge to do it right. I mean, this is the safety of you, your family and everyone else around you while you're driving.

DOWN WITH SEARS!!!
