Brake repair is warranted in all of these circumstances, so don't delay in getting your car to a certified brake repair technician. This is one job that can't be left to amateurs; there's too much at stake. You may still hear your brakes squeal when stopping after having brake repair done on your car. This usually means that the technician didn't take the brake repair process all the way to the end, and you would be wise to return your car to the shop.
Some pointers on brake fluid: be sure to have your brake fluid inspected regularly as it can become contaminated with moisture and metal flakes. You should also not have your brake fluid topped off, as too much fluid prevents your brake pads from signalling that they are wearing down. Also be sure to have your metal on metal brake parts lubricated on a regular basis to maintain a proper barrier between them.
Lastly, be sure to have your brakes inspected at least once a year, twice a year if you regularly haul or tow heavy loads with your vehicle, and have your tires rotated every 5,000 to 7,000 miles. Evenly worn tires help your brakes do their job properly by creating an even friction with the road surface. After all, the brakes may stop the wheels, but friction between tires and road stops the car.
