Brake fluid isn't supposed to be topped up. The system is designed so that the level in the reservoir will go down as the pads wear.
You should change out the brake fluid every couple of years, but other than that, adding fluid is a no-no.
I agree..except in the case where the reservoir is down to the level that says "low".
the brake fluid isnt actually on the "low" but 3/4 full. the brake pads was replaced a about 6 months ago..so I guess the tech did not top up to full when he did the job..
thanks for the advice guys.. I would have top up the brake fluid myself and cause damage to my car.
