2011 Discovery diesel 40x,
The front brakes are squeaking so loud it's driving me nuts...any body got a cure for this problem other than replacing the brake shoes? Only 40k mies on the brakes.

Squeeling is generally caused by glazed brakes. Glazed brakes can be caused by numerous things. Riding the brakes, not braking hard enough, grease from a blown axle seal. There is really no way to fix them other than new shoes, and possible turning the rotors. If the rotors are burned or glazed then turning is all you can do.

I would expect your coach to have front disc brakes. Every 40 footer I've seen since 2002 has had front disc brakes. If that's what you have you can check that the anti-rattle (pad retaining) clip is still in place.

Some brake pad brands have more metallics in the friction material then other brands and those tend to squeal more. If that is the case (or they are glazed, as mentioned before) the only real fix is to replace them.

Also, its not uncommon for the rotors to get some surface rust on them from sitting - in which case the squealing goes away after a few stops.

Seems to be a very common problem in motorhomes, especially one's where exhaust brake is more often used. Since brakes are used more lightly the discs or drums can become glazed and cause squeaking. I notice it on my rig as well when first starting out but after a few hard stops with brakes the squeal goes away. Take a look at this thread discussing the issue and possible remedies.

Have you tried a few hard , and I mean HARD stops?
Go and put everything that isn't secured away, then go out to a deserted highway.
Speed up to 50 mph, then hit and hold the brakes hard, as in a panic stop.
Do 4-5 hard stops, this may help.
Happy Glamping.

This would be my first thing to try. If that doesn't work you can always pull the wheels and scrub the front discs in a crosshatch pattern with sandpaper to remove the glaze. I also do it to the pads. Then start performing zone hard stops regularly to keep the squeaks away. In very rare cases you might have to swap pads for non metallic pads.
