Today I notice on my 90 bonneville SSE that everytime I press on my brakes the brake light and ABS light comes on then goes off (on the dash) and does not come back on unless I press on the brakes again does anyone know what may be the problem?

Check your brake fluid level. It'* low.

Brakes and fluid are all fine.

Then you will need to check the sensor and the plug. Something is telling the PCM that the fluid is low.

Where is the sensor and plug located?

Should be on the side of the master cylinder, but I can't say for sure with our year.

I'll check tommorrow morning, I would hate to take it to the stealership to find out the problem. thanks for your help I'll keep you posted.
