Drum Brakes Question
Bought a 98' Holiday Rambler 37' Endeavor DP and after being out for a little over 3 months find that when first starting up to pull out of a camp ground that at a slow speed of say 5 mph the brakes make a lot of squeaking/not grinding noise that disappears once I get up to a higher speed and use the brakes. I can drive for hours with no brake noise and then back down to lower 5mph with no squeaking. So it's only after sitting for a couple days and only at low start up speed.
Thanks in advance for all responses.
Jim

Probably just some rust or maybe brake pad dust caked around the parts while sitting. Moisture cause it while sitting, but a few minutes of driving heats the wheel up to drive away moisture and also breaks loose on build-up.

Two Theories:
1: The drums are rusting and you are hearing the rust being worn off by the shoes.
2: Now my motor home the "parking brake" is a single drum on the transmission tail shaft. it is operated by a cable, nto levers. Most parking brakes on Gassers are like this (Air brakes are all levers and air motors and hoses and valves, and springs, they work differently)
Well, on the cables, they can rust up and bind, Thus they may not fully release. Common on cars in northern (Salted) lands. This is, in fact, my one warning about Surge Brake systems for towed cars.

X2 on Gary's thoughts above. Ours will do the same after a few months of non use. I think the braking surfaces inside the drums are collecting surface rust and you're hearing that getting ground off in the first few stops. For that reason, I'm pretty careful to make a couple stops prior to entering a highway to make sure everything is OK. First stop in reverse can be a little nerve wracking in ours too, if you aren't expecting the noisy heavy vibration/chattering caused by that same rust.

X3 here. Have no answer for it but it hasn't effected my braking.

While it is annoying is normal. Sometimes after driving in wet conditions and then parking for a long period the shoes will actually rust onto the drum. I will take a fairly harsh rocking motion to break them loose. Again annoying!

I believe it is moisture in the brake shoes. Our Holiday Rambler on Freightliner chassis (2000 model) would do that after sitting just a few days in a humid climate. Going 2 blocks with the brake lightly applied would cure it for the day.
