swapped the hydrobooster out Reply #15 – July 13, 2008, 08:51:33 PM Quote from: Red_LX;214022I have an SVO master cylinder on mine. Stock prop valve, 73mm front calipers. Admittedly, the pedal is a tad soft, but it hauls the car down pretty well, I've made several panic stops since the swap and I've had no problems with locking up the brakes.FWIW, I've read that when using the SVO MC, the acorn nut needs to be turned out about 1.5 turns to stiffen up the pedal feel. It's only what I read though.Supposed to be a 0.010" clearance between the pushrod and MC. Quote Selected
