Seems like the small diameter piston that triggers the brake fluid pressure warning light in my new MC is not centered, so the small diameter segment is not aligned with the hole for the switch plunger. This photo shows the piston removed from my old MC.
Does anyone know how to reset or recenter the piston in the MC? (not reset the plunger on the switch) |

See my build thread for more details, but I ended up removing the MC from the car, and then removing the warning system piston from the MC.
The first problem is that the centering spring is missing (compare to the piston from my old MC on top). Remember, this is a brand new MC. Attached thumbnail(s) |
