Check the handbook : Vehicle that have been standing for any long length of time may have their lights on for at least 40 seconds and that includes ABS. A ABS ligt stays on until you are moving at a certain speed. (sensor check) Also there is a certain method the bleed the brakes, check the manual. I had a soft pedal and pulled the ABS relay while doing other electrics, drove forward and back pumped pedal and when I replaced the relay got hard pedal. Also try this old Army mechanics trick : Pump up the pedal and jam a piece of wood between the steering wheel and pedal, leave on overnight, next day = Hard pedal. Works well on Series. The small air bubbles rise to the top as there is a valve inside the system left open. We used to leave them for a couple of days and got great brakes. Remember the leather wheel needs some protection, rag or paper between the wood and wheel. I use a old broom handle and a piece of wood 11" long with a hole for the pole. pole on the pedel and pump up, jam the wood against the seat.

Plus 1 to that, the whole system needs bleeding as per RAVE, it aint simple

A lot easier with 2 of you, that's for sure. Make sure you get all bubbles out when bleeding the booster screw and top up little and often.
