Is intersecting at the proportioning valve or master cylinder?

I believe mine cleared but I had the old non adjustable version of the PTFB braces that used thinner tubing. Been a while so I can't remember. The ones now are more beefed up so that might be a problem for you. You definitely shouldn't have problems if you were to switch to manual brakes.

More important thing to know right is where the intersection is.

I have the hydratech hydraboost with the polished CPP MCPV1 master cylinder. the master cylinder is 8.5" long and 4.5" wide. it also as the built in proportioning valve looking for another master cylinder that's not as big that will fit. will check later to see how much room I have
