Hello, have bought a small 97 winnebago a-class. Brakes feel soft and pedal goes almost to the floor when you want to really stop. ive put new flexi hoses on, new pads, new master cylinder, and bled the sytem out about a million times! have vacume bled it to. also have fully serviced and adjusted the rear drums. still the pedal still seems to have a lot of play and feels soft. its driving me nuts! Are they all like this or do i have a problem? also, it starts to pull to the right after about 20 mins driving when breaking. then the next day it'll break straight again!
