Front brakes

Hi all,
Having taken delivery 3 months ago I have noticed that when I let off the brake pedal on my Dutch Star 4018 I get a Groening sound from the front brakes only. I do t know if this means that the brakes have to brake in still or is this dust on the pads? Any advice... Thanks in advance.

I've never heard a groaning out of the front end, but the disc brakes do make a whistling or howling noise when you release them. They all do it and it's caused by air being released after you let off the brakes. The valve making the noise, can be replaced for a quieter one, but most just got use to it.

Thought I had missed you in a welcome to the forum and irv2 but found this link in one of your threads.
Hope you get the bugs out of your new coach soon so you can enjoy it and welcome to the Newmar family and many miles of safe travels in your future.

If the noise sounds somewhat like a horn it is normal. This is common & the friends we travel with their coach brakes sound the same. Nothing is wrong with your brakes

There's a kit or replacement part available that's quieter
..if you call the chassis mfg.

The valve is designed to let off the Air pressure more quickly, so you don't have to wait for it to vent way back by the main axle for the front brakes to modulate after a brake application.

FL in Gaffeny replaced a valve for $100.

Once the wife heard it was $100 to stop that noise it was a no brainer.
