Braking Issue on Fleetwood Flair

Hello,
First time posting and new to rving! I am in need of some help on my new to me 1996 Fleetwood Flair. It is on a Chevrolet P30 chasis. I have searched for an answer to my problem but have not found an exact match to the problems that I am experiencing.

Here is my issue:
After braking hard such as coming off of an interstate exit ramp or coming off a hill, I am getting a major vibration after stopping and starting again. It doesn't shake or anything while stopping. After a few miles down the road the vibration or bouncing goes away. The best way I can describe the vibration is it is similar to a wheel being loose or out of balance. It is a pretty noticable bounce or vibration and is speed related. I can keep it from doing it if I don't brake hard.

Any ideas?

Thanks in advance,
Jake

    I had the exact same problem this spring. My passenger side caliper was the problem. I changed the rotor and hub assemblies with new bearings, the calipers, the brake pads and the brake hoses. I got all the parts from Napa.

    I don't know if there are beads or powder in the tires or not. I didn't put these tires on. It feels just like a flat spot on the tire so could that be similar to how the beads or powder would act? Also is there any way to know if it has beads in it without breaking down the tire?

    Typically I think you can hear them rolling around when starting out and sometimes after a stop. I know my Centramatics, which are sort of a bit similar, make a very distinctive sound when tooling around at low speeds, kind of a shooka-shooka-shooka sound.

    Since the problem doesn't go away with speed but rather with time, I would be very surprised if it's tire balance beads or something similar. They ought to get themselves distributed and sorted out at a relatively low speed, maybe 25-35 mph, below where you tend to feel out of balance wheels/tires. I'd guess a warped rotor and a somewhat sticky caliper, or something along those lines, but that's just a guess.

    Did your last tire guy sell you "balancing beads"? They seem to help keep tires balanced but a sudden stop can lump the stuff together for a short period of time making a bumpy ride until they redistribute themselves.

    The P chassis have had a problem with front brake hoses.
    The hose will fail internally and act as a check valve and not release pressure.
    I had that problem with a 1983 Winnie and a 1989 Southwind class A's.
    If you can look at the calipers you should see that rusted/overheated look.
    Also if you go to buy the new hoses you need to take the old hoses to match them up. The hose/frame bracket is different on some units.

    Sounds like you have a caliper hanging up or could be slide pins.
    If your steering wheel shakes when it happens it’s front if not start with the rear. What you can do is take it for a ride to get it hot, hit the brakes hard to get the problem to start and as soon as it stops shaking pull off in a safe area. Walk around and put your hand near the lug nuts, you should feel more heat on the one that’s acting up

    I haven’t looked at the rotors and brake pads yet, at least not with the wheels off. Figured that’s probably where I should start. It kind of seems like a warped rotor but it seemed odd to me that it only acts up when the brakes get hot and not when they are applied. I don’t know about the brake fluid. The RV is new to me so I’m sure it could stand a good flushing. I will also look into the master cylinder. Thanks for the replies!

    When was the last time you looked at the brake pads and rotors? While you're at it, when was the brake fluid last flushed?
