VladFomin Posted December 27, 2014 Share Posted December 27, 2014 I'm in the middle of replacing the entire brake system on my 77 280z. New booster New 15/16 master New stock front brakes New rear disk conversion I read that I can remove the brake pressure sensor block completely. True? Also read that I can run a proportion valve from a turbo zx that had rear disks. True? Do the factory proportion valves regulate fluid to the rear wheels and the wilwood one regulates fluid to the fronts? On a stock valve is it just a pass through for the r/f caliper? Can someone maybe do a sketch for me of a factory zx valve installed w/o the pressure sensor block? Thanks Quote Link to comment Share on other sites More sharing options...
Phantom Posted January 1, 2015 Share Posted January 1, 2015 Go to the brake section of this forum and read up on the posts. In a nutshell you remove the brake pressure sensing block and the stock proportioning valve. You then place an adjustable proportioning valve in the rear brake line and adjust it to give you the correct front/rear bias. Which rear brake conversion are you doing? Techno Toy tuning has just come out with a 4 piston Willwood system that retains the ability to have the stock Z emergency brake. Check into it if you haven't already.
