My recently acquired 72 GS455 has a set of unknown chrome headers on it, and they rub the proportioning valve on the driver's side and the steel brake lines on the passenger side. Anyone else have this problem? I will redo the brake system soon, and am contemplating moving the valve out of harm's way. I do not want to bake the brake system, if I can help it. Has anyone used an aftermarket, high performance proportioning valve on a project? Thanks, Rudy E.
You can remove the mounting brkt and install the prop directly to the frame. If you are going to replace the brake lines and don't car about originality, www.inlinetube.com carries a new kit to relocate the prop valve to the master cylinder (same set-up used on 70-81 Camaro/Firebird)
Thanks, guys. The car has low hydraulic pressure, mushy pedal, and the brake warning light is on. I intend on swapping out the entire system so that I know what I have under me. The whoa is more important than the go at this stage. I will not put it on the road until I iron out a few issues. The last owner said that the headers have been on the car for about 5 years or so, and they may have contributed to the demise of the master cylinder by broiling the fluid on and off. Thanks, Rudy E
More than likely the motor mounts have sagged and let the engine down thats why the headers are hitting.Mike D.
