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./ l4 S0 X5 x( t3 i0 @% e- t$ n$ 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...9 ]/ U1 G/ x+ x! u* I+ V& m
: J ~- k3 l: y4 V4 C; o8 n; xI 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.
