From Tom Walker, I have 2001 Patroit Thunder,40 foot,with a 425 cat, I was heading out for a weekend trip and noticed at the first red lite that my breaks were not working properly, I had good air pressure on my gauge (110) the pedel felt good, but I had to stand on the pedel and the coach rolled to a stop, it would not lock up!! I all most hit the car in front of me, I pulled off the road and unhooked the toad, and tried a couple of breaking excerises, again I had to stand on the break pedel and it slowly rolled to a stop. It still would not stop!! I bleed the air lines at the rear of the coach maintance panel, shut down the engine and did a air dump and restarted the engine and let the air pressure come back up(110) and the pedel felt good, I started to head for my repair center and the coach at 45 mph when I applied the brakes hard would only slightly slow down, to come to a stop it would take about 100 yards or so, any ideas?? Also I have experienced that my ABS lite comes on and goes off, I had it serviced 2 times and the right rear cable replaced only to have the lite keep comming on and off ??
