Okay, a few facts here.... 1) The original DeLorean master cylinder has a 63/37 split and is identified by the RED band around the end. The 50/50 cylinders from Lucas/Girling have a black band around them. 2) The original 63/37 is from a Saab 90 3) The 50/50 is much more common and is found on the 900, 99 and several others. 4) We exhausted the remaining stocks of 63/37's from Lucas Girling over a year ago. 5) The split is achieved by the two springs inside the cylinder acting against one another. If it wasn't such a challenge to disassemble them, you can recreate a "proper" cylinder from a 50/50 by swapping the springs out of your old one. 6) Under heavy braking, the fronts should lock up first - it is far safer to lose control and carry on in a strait line than potentially spin the car. This effect remains even with the 50/50, probably related to the larger diameter and track of the back wheels. 7) (to Marc) - you were very complimentary about my #4426's brakes. That has a 50/50 master, stainless hoses and a set of refurbished calipers. 8) DMC Texas' reproduction is the only correctly proportioned cylinder available. 9) Either master cylinder is better than an old spongy one. It's amazing what some owners seem to put up with simply because they don't know any better (never driving other than their own DeLorean). The DeLorean's brake pedal is more than capable of having a solid, thoroughly responsive pedal. We've done countless cars who've received a set of calipers, stainless hoses and a new m/c. Only one complaint so far which went along the lines of "I wanted them better, not psychic!" (he found it hard to brake gently). With kevlar pads, the brakes get even more serious :-) Martin DMCL Marc Levy wrote: >The one thing that is unclear to me, can we still get >the 63/37 master cylinders?
