Hi, Looking for some advice, I keep regularly getting the the handbrake warning light flash and make a loud alarm beeping noise 3 times. I have been told this is due to brake fluid level being low, but I have topped it now about 7-8 times in the last 6 months, surely this is not normal? Does this mean I have a leak somewhere possibly? Also, how do you know if a caliper has seized, what are the signs? I think one of my rear ones may have gone, it feels as know when i'm accelerating that something is dragging me back, as though the rear brake is constantly on. Advice appreciated.
