After the last autox as I was pulling out of the lot I noticed the brake warning light was on. I pushed the reset and it didn't turn it off.
The pedal did have act like the master cylinder was going bad or had gotten air in the system. If I pumped the pedal it would gain some pressure. Drove it home and the light had gone out at one point, but came back on. Spent Saturday bleeding the brakes and pulled pan off below the MC to make sure I was getting the switch reset. Pedal travel is not as firm as I would like it to be. Light will not go out even when I know the reset is pushed in. Tried switch from another MC same thing. Is the MC bad and preventing the light from going out? Or something else? |

There are two circuits in the brake system, and basically two master cylinders inside that one housing. There is a passage connecting the two, and a plunger inside that passage. If it moves too far to one side or the other, it closes the switch.
