Skoolie Air Brake System Repairs & Info (R12 Relay & Pressure Protection Valve)

Mke's still wrenching on the bus: this time it's more repairs and great info on our skoolies Air Brake System! A few videos ago, we replaced the D2 Governor, thinking that might fix our air brake issues. Then Mike did some more research and discovered that our R12 Relay Valve was leaking... but that still didn't fix everything! More research led to replacing our Pressure Protection Valve, and that was the final part needed to eliminate all our leaks. In the middle of all that, Mike also changed our annoying air brake buzzer to a more pleasant-sounding signal. And that pretty much buttoned up all our issues in the entire Air Brake System!

We are Mike & Kerry, the proud owners of a 1992 Bluebird rear engine (pusher), 40' school bus! We named her Bussy McBusface in honor of the RRS Boaty McBoatface travesty! We're building a Tiny-Home-in-a-Bus for full-time living in the most adventure-friendly way possible! In other words, Bussy will not be parked in our driveway, waiting for weekend or holiday getaways... when we finish the build, we'll be packing everything we're keeping into the bus and driving away from this old house forever! We plan to be boondocking the majority of the time, so you'll see that reflected in our choices throughout the build (100 gallon water tank, composting toilet, solar power system, etc). We'd love to have you stick around and follow us on our journey, throughout the Skoolie Build, and to Infinite Adventures Beyond! Mike & Kerry
