James, I did everything to my car...new master cylinder, front calipers, all new lines, even a different bias valve.(by the way, I used the emergency brake tube to run the line to the rear "T") I still chased a hard/soft/funky brake pedal. Finally I replaced the brake booster...AMAZING the difference!!! Also, since anti lock brakes are specifically disallowed, pitch the control unit and associated wiring. In addition, the stock E30 circuit had a pressure reducing valve in the rear brake circuit...remove this if you don't run a dedicated line from the bias valve to the rear "T". Chuck
