I've had this issue for like a year now its getting more constant . The noise is coming from drivers side behind dash . Now i could make the noise come on and also if i pump the brakes noise comes on and off . Has any one have this issue on their GS300. Ive heard alot of different things brake actuator , relay , computer . I just WANT to fix this noise ( its annoying ) . Really appreciate your help on advance .

The 2GS doesn't use the engine vacuum for the brakes. It has an electric motor with a hydrogen accumulator that turns on and off as the brakes are applied to keep up the engine vacuum. The noise you're hearing is likely the motor turning on and off.
