Primary operator (wife) reported yesterday that she was getting an intermittant Brake Failure indication (not parking brake or bulb failure indicator). I drove the car last night and saw nothing. Resevoir is still up. Today she calls and says she's seeing it intermittantly again. (She said it came on immediately when first starting the car, BEFORE pressing the brake pedal.
I haven't gotten a brake failure indication since about 15-20 years ago on my 140. But my experience then was that once the shuttle switch was thrown one way or the other, you had to unscrew the momentary switch from the valve block and re-center the shuttle with a tiny screwdriver. Are these "new" cars more likely to re-center themselves?
Also, I see there is a resevoir level sensor on this car that I assume is also wired to the brake failure light??? Besides a low fluid level, or a brake cicuit imbalance, is there anything else that can trigger the light?
Do the fluid level sensors ever get dirty or in some other way send false signals? Getting a light immediately upon start-up before pressing the pedal makes me start to think along those lines.
Are master cylinder re-build kits a thing of the past? I seem to read a lot of stuff about people replacing the whole M/C here on the BB.
TIA for any suggestions.
