At the begining i was thinking just was the hand brake switch or something turning on accidentally because it always happen when driving in a downhill where i have to brake faster than usual to stop the car. :huh:
But I just noticed it happens anyway when I need to brake fast and push hard the pad, then the red brake light turns on until I release the brake.
The user manual says something about ABS light and EBD (not sure) braking systems, my picanto dont have ABS so I just think on something happening to the electronic brake distribution (EBD) though its frustrating not to have a workshop manual.
yes , had this happen loads during my time with the pic . the level only needs to be a little off max and under harsh braking it will make the light illuminate . nothing to worry bout , top your levels up a little , but bear in mind your pads are maybe a little thin now and thats why the levels have dropped . take care swampduck
