"Brake" Warning Light under Acceleration

[Lawrence C Leung]

Both fluid levels up to snuff. I did notice one other thing. This only
happens accelerating from rest. Accelerating while in motion (such as
passing) doesn't trigger the light. So, my previous description was
somewhat wrong. Also, seems to happen more when the engine is cold.
