1990 Euro Dashboard Brake Light intermittently on

Hello All:

Title says it all.

Changed calipers rotors and pads last year. Not much miles since then.

Bad master cylinder?

Bad master cylinder sensor?

Thanks in advance,
Bob Sliwa

Make sure the switch on the e-brake is clean and not corroded or rusty. Check your fluid level too.

Also check that the e-brake pedal itself is not the cause. Sometimes the cable stretches, or is out of adjustment, and if the pedal return spring is a little weak, it can "sag" just enough to light the light intermittantly. You can test this by putting your toe under the pedal next time the light comes on, and lift slightly. If the light goes out, you know what to do.
