Evening all,

I've recently upgraded my front brakes to Wilwood Superlites 4 pot

Now I've done a full bleed on the system working from the rear to front furthest away from servo.

I get a nice solid pedal during bleed but when car is started and running Im getting huge fade ...... The pedal is firm then sinks to the floor.

I've repeated the bleed a number of times but no joy.

I've also fitted a new master cylinder. Any info on this or help will be greatly appreciated.

99%, you still have air in the system.

Try leaving it overnight, gives a chance for all the air to settle in one place. Sometimes repeated bleeding makes things worse rather than better

You are doing it correct, as in starting from the furthest bleed nipple.

Check for leaks, and that the plastic header is seated correctly on M/C.

I did think this just got so frustrating. Ill leave it over night and try again. Many thanks for the reply.
