The PVC hose test

PVC hose vs brake fluid test. This hose has been hanging since 2011 on the workshop wall to test if a standard air hose can take the brake fluid as a replacement hose in the Vanagon clutch system. As you can see, it is still dry and fresh.
The hose going to the slave cylinder can't be bought any longer, but now you know where you can find one that survives the fluid.
