brake line setup/routing

i know im not a hot rodder but i am a racer i was looking at the routing diagrams that were posted for single outlet masters and how to run lines i am having this same issue i do have a duel line master from a 66 bronco mounted on a wilwood floor mount brake peddle it is two lines but i was told to converge into one line for all brakes i know this sounds crazy but my lines will be mostly in the passenger compartment and run through frame rails but i need to achieve more rear brake bias but am not allowed to use proportion valves i guess this is the best way to do this but my problem is referring to the diagrams posted is this the correct way to run my lines for one outlet

If this is a race only vehicle why not just use a single reservoir master cylinder? Are you allowed to use an adjustable valve for the rear brakes?

Older cars like my 65 Mustang used a setup like you're after. It uses a junction block that looks like a proportioning valve but is hollow inside. Look for an older car with a single master and 4 wheel drum brakes.

No proportioning allowed? They don't like you? The only real way to adjust bias that I know of is to vary the size of pistons/calipers/wheel cylinders. Larger piston at the wheel equals more applied pressure. More pad/shoe area equals more applied force.

Grind away about half the material away from the front pads so you only have half the pad contact on the rotor. You can tune for track conditions by experimenting with different pad variations to get more or less rear bias. Increase the bias to loosen entry. I imagine it'll be tight on entry if completely stock for the factory does that on purpose.

brake line setup/routing

thanks i was gonna trying dif size calipers im using the bigger camaro spindals but i only have access to smaller piston calipers that are metric will these be compatible with the big stock gm calipers or will they even bolt onto the camaro spindals i was told run a smaller size on the right front with my one line setup and this should give me what i need will the variation of pads work with my caliper variation or should i just scrap two dif calipers and work with the pads god i just wish they would allow the proportion valves or duel masters there not making things easy for us

I think I would keep the metric calipers because they are much lighter and you can get them with different size pistons.
