Question Brake shutter

Sometimes when I hit my breaks they 'Shutter' bad enough that it shakes the whole MH. What could be causing that?

Drums or disc? Either way, it's likely a warped rotating assembly. Usually due to severe overheating, sometimes due to dragging like a caliper hangup, sometimes due to over use/improper use like riding the brakes, and usually cannot be turned. If it were due to severe overheating, pads/shoes likely need to be replaced, as well as about everything else in the wheel system from the flex line out, slave cylinder/caliper, etc. Replace in pairs, both fronts or both rears, regardless of the shape of the opposing brake. Or you can take your chances. Personally, not being able to stop is worse than not being able to go.

Probably brakes but also possible loose wheel.

brake shudder

If your are on a Workhorse Chassis, very likely warped or cracked rotors due to dragging calipers. There was a recall to replace faulty calipers some years back.

X2
If they are disk type. At the age of your coach and assuming you have not recently overheated the brakes, like on a steep down hill grade, then a caliper is probably sticking causing the rotor to overheat and warp.

Loose wheel, bad wheel bearing could be possible. These might also cause clunking noise when turning.

If it is caliper/rotor issue, I would replace both front brake assemblies from the caliper out. Caliper, rotor,pads.

Severe steering wheel shudder tells me the issue is with the front steer axle and they are probably disk brakes. Out of round drums will usually surge more than shudder.

You may have disk brakes on front, drum on rear. Possible you have disk all the way around.

Like Tony said, doesn't matter how fast you are capable of going if you can't stop.

Check the rubber line that runs to the brake assembly. Years ago I had a brake hanging up and the line had broken down internally. A flap would drop down and act like a check valve keeping fluid in the caliper.
Also, the metal bracket that mounts the hose to the spindle could be building with rust and squeezing the hose shut. Had that happen also.

Good luck.

Definitely cheaper than caliper replacement. I'm guessing still needed rotor and pads.
