Brake opinions for my current plan 68 camaro C6 master

[jasonz28camaro]

I have had many issues with my current brake system that has an unknown master cylinder size and unknown combination valve. It’s power brakes with a 7” booster. I’m looking to start over with a new C6 vett master/booster and redo the old brake lines at the same time and would like opinions on the size tubing I selected to see if it will all work together.



My current brakes are LS1 up from and wilwood 12” in the back.
Front and rear have 3/16 coming off the master to the combination valve, dual 3/16 outlet off combination valve to the front brakes and a single 1/4” outlet from combination valve to the rearend where it tees off to 3/16”.

My new plan (currently underway) involves a 2006 C6 master/booster (1” bore) with the same brakes above. No combination valve. I plan on using DSE adapter fittings on the master and running 3/16” tubing. Fronts will have a tee below that will supply each side. The rear will be 3/16” off the master to a proportioning valve hidden on the subframe below then travel to the rearend to a tee to supply both sides.

Concerns:

the C6 master is setup for 1/4” tubing from factory but the DSE fittings I’m using are more or less adapters to allow 3/16 tube and are m12x1 3/16” inverted flare. Would there be an issue if the master was intended for 1/4” tubing, not 3/16? I know this is a common thing people do and must work but I’m just curious.

Am I ok to use 3/16 everywhere or should I use some 1/4” tubing anywhere?
