well you might try lubricating all the pivot points in the pedal and that will be solved since the pedal returns via a spring. if your brakes are stuck on its moisture in the lines especially if you stored them in a damp environment. above all get your friggin hands dirty and take a look instead of whining that we didnt answer the question. how do you figure we know all this shit if we didnt do it once or twice. -- max everyone is entitled to his own opinion he is not entitled to his own facts. sen. daniel patrick moynihan of new york i have 3 older dodge trucks all have come down with sticky brake pedals . the pedal becomes vary hard to press down with no rebound... i have to pull the pedal up buy hand or my tail lights stay on... when i apply the brakes they want to lock up!! and stay locked untel i pull the pedal back up. .. . . .. is this the brake booster is this a vacume leak.. maybe in the manafold or the boster is ths a big problem with dodge trucks it is stange how all 3 trucks have developed the same problem. .. pease help!! the trucks are all half ton pickups ranging from 1975 to 1981 problem started after each vehicle was stored in a damp atmospher last winter . . could it be some kind of vacume blockage from crorosion or carbon build up thank you .
