How to bypass/disconnect the HR-1 Valve on Chevy 454 33' RV?

[Thor33]

Hello, I posted a question about this problem about 6 months ago and thank you for the help...however, I thought I would just ask if one of you could tell me where I find the HR1 valve on my Chevy 454 for the hydro boost brake system as I would like to disconnect the actuator linkage/or just bypass it and only use the manual emergency park break....where do I disconnect the linkage that operates the HR-1 valve....or better yet....where do I find the HR-1 valve on my Chevy P30 33' RV?
Thanks for any help 🙂

Just follow the line from the hydrualic chamber/spring that applies the brake. Then cap that line at the valve.
