Nissan Repair: brakes, nissan altima, ford dealership

Question
Hi,
I have a Nissan Altima SE 1999. Lately, when we start driving, our car makes a ringing noise, which seems to stop temporarily when we apply the brakes.
The brakes themselves seem to work fine. I also checked the brake fluid, which is low but still way above the min level.
Can you suggest anything?

Thanks so much,

Bart

Answer
Bart,

It sounds like the brakes are dragging.  I would replace the pads and sliders with new parts and you should be fine.  Also, replace the brake fluid with Ford High Performance Brake Fluid.  Five bucks a pint at a Ford Dealership but worth the money since it has twice the boiling point of the original fluid.  And, it is DOT 3 so it will not hurt your braking system.  Remember that brake fluid should be flushed every two years and no one seems to do this.
