Hello, how's everyone been?

Drove my Corvette ('95) to work today, went to take my exit and I noticed my "Brake Pressure" light was ON!

I slowed down and checked my brakes, which still worked.

When I go off the highway I turned it off and back on, the light went out but came back home later.

I check the fluid level, looked normal.

I looked underneath, no puddles.

I'm thinking either my booster or ABS module took a dump.

I'll dig out the FSM (factory service manual) when I get home.
I'm assuming ABS codes will come up on the dash.

BTW it's SUPERCHARGED and there is a check valve, but it of course could have gone bad

any advice?

Sometimes the sensor can stick. Can also be a loose connection at the sensor. Have you flushed it lately? Should be able to check codes on your model.

there are two sensors that will light up the brake light... three if you count the parking brake.

However, one is the pressure switch, and that screws into the side of the master cylinder. the other is a level sensor that slides into a void between the two halves of the reservoir.

Then comes the wild card... there is this blocking diode thing that keeps the two sensors from freaking each other out. Mine failed on my 92 and a) never found it in the harness and b) never figured out what its rating was.

There is also a c), I never looked deep enough before selling it....

On the way home the light never came on.

I read the FSM, it's a differential sensor.
So I have a leak in the system, from the lack of fluid, I'm gathering the o-ring between the two circuits is going.

BTW the FSM has full instructions on rebuilding both the master cylinder and the booster, if you can get a rebuild kit.

Those 23 year old lines have never undone, they generally break and need to be replaced when they are that old.

I just need to figure out how far I want to pick at the scab.

I did by 6 piston calipers for the car, but I never put them on since they only fit my racing rims which will now not pass MA inspection do to the width.

Which means I'd need a different set of calipers, which need anyways since the old ones are showing their age.
