Ok, so 94 K1500 blazer. When i sit at a stoplight, the pedal receeds as i hold it, where if i keep the pedal in one positon, the truck starts to roll after 10 or 15 seconds, requiring me to push it down farther. Before i start replacing components, do you guys think it would be worth checking/flushing the fluid? Its been around 4 year/52k since the fluid was changed. ALso, i vaugely remember some trick to check if the fluid is contaminated....where you put a drop in water or something. Can someone please describe this? Also, if i do flush/get the fluid flushed, i was thinking about replacing the rubber hoses with SS braided ones to try and firm up the pedal a little. God forbid i try and get rid of the charcteristic chevy squishy pedal....just wouldn't mind firming it up a touch. Think the ss lines are worth it? Thanks!
