Hello,
I. Have disc brakes and need to service them, not sure where to find parts. This is a Chevy chassis, but not sure of model. There is some type of booster, would like to know more about the system before ‘digging into it’ . Does anyone have advice?
I love my Airstream,and enjoy this forum!
Thanks

Welcome to the forum.

FYI there are sub-forums for motorhomes [MH] like yours, where there should be more specific MH "brake" advice, than in this general forum for trailer brakes IMO:

These search results may also lead to productive pastures IMO:

Or any other motor parts supplier.

Just look for the motorhome chassis option, but, as Peter say, best place to start is the motorhome section of the forum.

And the service manual is here

You have a P-30 chassis (actually it was a P-32, but everyone calls it a P-30 motorhome spec).
