i noticesd that my truck really doesnt stop like it used to...i know the 285's dont help but still i feell there is something wrong. The truck has trouble stopping on when i depress the pedal...but if i release the pedal and press down again it stop s awsome.....I know when you have to pump up the brakes theres usually something hydralicly to blame..has anyone had this happen before..i dont wanna through in a master cylinder just yet

 

pads worn down might need adjustment. air in lines. or master cylinder. would be my guess

 

the front pads are goo, but i havent checked the shoes yet...hopefully thats all it is i did smell gear oil by the drums so im sure something is soaked in there but i dont see any drops externaly.
