Good product but hope I never need again
I've never put a master cylinder under the floor in any past street rod builds. This is my first. And first for all the problems that come with it. Never heard of a residual value till doing so now. The extra costs and headaches are a lot of trouble just to have a clean firewall. From here on, I'll put the master on the firewall to save in many ways.
As for a con to me was. This might sound dump to a lot of folks. But I've never heard of using pipe sealer on break lines. The residual values has NPD threads. Which I've never worked with on break lines. So I was chasing leaks till I was blue in the face. I called for support to find out I needed hydraulic pipe thread sealer. It's very expensive for a small bottle. Don't understand why the company can get together with the pipe thread sealer company to packaging very small tubes like the grease tube's you get with break pad backing to stop squeaking. A very small amount goes far. An it would save trouble for poor guys like me that doesn't have the experience to know it's needed. We're always learning!
