Do the Ecotec/Brammo cars use the Tilton master cylinders? My Atom 3 does, and after two of the standard hydraulic brake switches failed (each requiring very high pedal pressure to activate the switch), I installed a commonly available (at performance car parts shops) hydraulic switch. End of problem.
I could not easily locate the banjo bolt pieces to rig this new type of switch into the existing brake line connections, so I just removed the bleed screw at the top rear of the master cylinder, and put the new switch in there. The threads on the Tilton master cylinder are AN threads, so you just need a simple adapter that goes from a male AN to female threads compatible with the switch. These adapters are also readily available. I left the old switch in place as it has the required bolt for the banjo fitting on the brake line. Connect the wires to the new switch, and you are done.
Once armed with the required parts, this installation took about 5 minutes. So little air got into the system that I did not even need to bleed the brakes. I did not take a photo of this. If anybody wants photos, let me know and I will take a few.
