68 B/F-500 brake help

[KaptnKAOS]

Not sure if this is the right forum for me or not...

I have scanned the tech articles and the member profiles and it looks like there are mostly wee trucks here.
I am working on a 68 B/F 500 bus. It needs brake work.
I've been looking for info on updating the brake system.
Anyone have any experience with 500-600 B/F series trucks ????

Please get back to me if you do...

Thanks ahead of time
