I went down a steep grade with my 93 bounder, 28', P30 chassis.
When I reached the bottom, the brakes were hot. I am also towing a small suv. I Drove another 10 miles and pulled over at the next town for a break.
One half hour later, I went to leave. I put my foot on the brake to start it, and when I started it the brake pedal went all the way to the floor. I pumped the brakes a few times and still nothing. I waited another few moments and pumped the brakes again, and then they came back to normal. Does anyone know why it did that. Is there any solution for braking going down a steep incline, like an engine brake.
