i got a 99 integra LS. couple days ago, my brake light indicator came on even i release the parking brake. i checked the brake pad and the fluid. they are ok. then after i drove like 10-20 mins, the indicator light turn off. i turn off the car and start again. the light won't on. and i found out it only will on when you haven't start your car at least over night. is something wrong with my brake system? i install aem big rotor kit on my car. will that affect my brake system? plz help!
