hi guys.
i wonder if u guys could help me out here. this evening i was on my way home from work. i was pulling out of a road into the roundabout. as i was accelerating, i saw the brake warning light turned on for about 2-3 seconds before going off.

my handbrake lever was down, brake fluids are full and brake pads are still thick. i wonder what caused it?

my car is a Perodua MyVi 1.3 auto bought in March 2006. this model is the same as Daihatsu Sirion / Toyota Passo 2005.
