Hey dudez, I jst performed the S13 four piston conversion on a clients car unsing R32 type M calipers. I'm using new DBA slotted rotors, custom brake lines and the calpiers have been professionally reconditioned. The problem I'm having is that even after 4 really good bleeds tha peadal still falls to the floor. Obne of these bleeds was done at a local wheel center so lack of experiencs shouldn't be a problem. I read many articals covering the conversion that there is no need to change the master cylinder. The car is a 92 2L NA with no ABS.

In some instances, it's possible to have an airlock in the braking system, which will make bleeding impossible until you use a device known as a pressure bleeder found in most professional brake workshops.
Another common problem that I have seen with these types of conversions is the calipers being put on upside down, with the bleeders at the bottom, allowing air to be trapped in the top of the caliper. If this is the case, then you will never bleed them until they are turned up the right way.
Also, some master cylinders have a bleed nipple on them, which you should bleed first, then a junction box (if it also has one), then the slaves themselves.

Either that or the master cylinder is screwed.
