Hello, I have an rs13 and ater swapping r33 gtst disc and calipers I decide to eliminate ABS and install a new brake master cylinder from z32 the part is japan parts/ashika cod. PF-194 OEM:40206-40P02 http://db.japanparts.it/cat_japan/de...DI-194&fr=4299

The problem is that my pedal is too soft and go down and another strange thing is that in my rear brake there is alway pressure! and I don't know why, it's possible cause that this BMC works only with abs? Or I missing something?

I think it's BMC problem .....Probably the rubber seal of the Front brake caliper is worn out or old......Changing the Master Brake Cylinder or just the rubber seal inside the BMC piston.....

I don't think it's ABS brake problem at all.....Since Non-ABS is less complicated than ABS....and it's just really straightforward......BMC to 4 corners calipers.....

Make sure that you put the calipers in the right position....Always put the bleeder valves up high....if not, the air will trap inside the calipers, which still cause your brake pedal down to the floor anyway....
