after doing all the bombs to my truck i now have to figure out a way to slow it down better. the brakes on my truck are very stiff. i recently changed the fluid and bled all of them which made no difference. if i use the pump the break pedal 3 times pretty quick i cant push the pedal down at all and the truck doesnt slow down, feels like i dont have any brakes. this is a problem if i am in a traffic jam. i have no idea what it could be. all the pads and drums are fairly new. has to be something in the master cylinder area or maybe even the calipers or wheel cylinders. has anyone else had a problem similar to this. any help would be great.
