Brake problem mystery need help???
Hello, bought my 2003 dodge ram 1500 2wd new in 2003. Had a problem where I think I had warped rotors. replaced them and the pads on both sides. fixed the wobble when braking. New problem with the brakes. They appear to be very soft when braking, almost to the floor. hissing sound when it happens. If the truck is not running seems like you can pump it a few times and seems to preasure back up. Would this be the master cylinder, or the power brake booster. plan on bleeding the brakes in the next week to see if this helps. Truck has just hit 81,000 miles.
Thanks for any insight
