noticed it a week or so ago that when i had my windows down i could here a "hisssing" sound coming from the car as if the brakes were catching . the brakes were starting to get low anyway so had the front disc and pads changed the other day, thinking my problems were solved to find that it hasnt went away . could it be that i need the brake fluid changed ? just wondering if anyone else has had anything similar as im getting sick of the extra attention i bring when driving along lol
