First off, may I ask, what EXACTLY do you mean when you say your fronts have been "REDONE, TWICE"? Did they put new shoes, turn the drums, just look at them, what?
Second, I'm pretty sure that Winne and Itasca never had any air over hydraulic systems but, who knows?
Third, the air brake systems, shoes and drums on these coaches, generally last for years and years, miles and miles. You should not have to touch them for most likely around 100,000 miles. At least that was the general conscensus that most replies were when questions about air brake longevity has been brought up in the past.
Fourth, yes, your slack adjusters do need to be lubed, on an every-so-often basis, it's listed in the maintenance sections of the manuals.
I suspect, that you have drums instead of discs but, without you stating different, I don't have proof. Drums/shoes can squeal at varying intervals, depending on condition of the surface of the shoes and, the drum contact surface. On our rig, an '04 Itasca Horizon, 36GD with the C-7 330HP CAT, they don't squeal unless I'm using them a lot, around town or, some grades before entering town. Then they'll squeal even with slight pedal pressure. Yep, I too will get the burnt smell, usually after a long decent down a winding grade upon which, in conjunction with the use of the exhaust brake, I have had multiple applications of the service brakes to assist the e-brake.
It is what it is. You can't use them without them getting to some degree, warm. Some rigs, will go longer without feeling the effects of a grade and therefore not present any squealing and some, do it way earlier in the application process.
Unless I missed it, what is your mileage on your rig now?
