JMortensen Posted July 19, 2003 Share Posted July 19, 2003 Hey 260DET, I've had the same problem with my admittedly inferior Z Quip late 280ZX setup on my 240. I was running the stock rotor with 4x4 calipers in front, and ended up taking the prop valve completely out, and still could not lock the rears in water! I suggest you install the prop valve in the front system. As for me, I'm saving for some bigger brakes front and back. Still looking at options, but I'd like to keep in a 15 inch rim, so I think that means 12 inch rotor max. Just wanted to share my experience...

260DET Posted July 21, 2003 Share Posted July 21, 2003 Thanks for sharing Jon, its always nice to know that others have had the same problem. But I seem to recall that putting the proportioning valve on the fronts may lead to a problem there. Something to do with inconsistent front/rear balance under varying braking loads? The obvious solution is to fit 2 spot rear calipers which have pistons at least as large as the front four spots. But I have to have a mechanical handbrake.
