Before I get blasted, I have searched HZ for the answer with no clear definite solution on what to do with the proportioning valve. Some say take the guts out of the prop valve, some say don't...
My Car-73 240Z
My Brake setup is the 81 280ZX 15/16 Master Cylinder, reman'd stock 240Z booster (I might upgrade to ZX later), 240Z stock proportion valve, 83 280 ZX rotors and calipers in the rear, 83 Toyota 4x4 front calipers that use the stock 240Z rotor direct bolt on caliper.
My question is what exactly I should do with the proportioning valve to make this system brake properly?
If I am missing some information that you need to make a clear definitive answer please let me know before posting. I am just trying to clear up some of the confusion that has been talked about on HZ for many years with different opinions on what works.
I will not drive my Z until this is fixed. I will never race my Z in a competition, and will eventually run a modest N/A engine with triple carbs...so HP will never be over 220 in case people are wanting to know what kind of power I will need for stopping my car.
Once again, I hate bringing up a topic that has been talked about many times, but I, and probably others, find many opinions on what to do with the prop valve when upgrading to disc brakes.
