If the brake warning light comes on when you apply the brakes, it means that hydraulic pressure has been lost due to a leak somewhere in the brake system.' J8 i; P' a3 H2 L; ?- X
If the brake light stays on, that means the sensor is faulty.
I thought the question was about the ABS light on? Unless the brake warning light has anything to do with the ABS light... % D) T7 l2 o9 s, `) W8 F& r2 f; ~1 L6 f0 @% P# C% W H
I am having the same problem with my car which I just discovered last night after I picked up my car from CDN Tire for the tire change. I sent it back to them for a checkup and they just called me that it was not caused by the tire change. (Note that both my ABS and Traction Control lights are on and I hear that clunking noise from the brake when starting my car). I will see what they find after they notified me that they'd charge me inspection fee.
