Brake repair is in truth just a car maintenance task, not a response to a major flaw in the system. Think about it, brakes wear down if they do their job correctly. Those squealing noises that you hear are signals that your brakes need repair in order to keep functioning properly. It is kind of like your oil light going on when the fluid level is low. If you top your oil off, all will be well. Repair your brakes, and you can keep on driving safely. Same thing.
Brakes do more than make noise when they need repair. If your brake light goes on when your parking brake is disengaged, have your brake fluid replenished. (You will be able to smell your brake fluid if a leak is the source of the trouble.) Rotor surface problems present themselves as a vibrating wheel or brake pedal. Grinding or growling noises mean that the brake pads have entirely worn away.
Any issues should be discovered in time if you have your brakes inspected on an annual basis. (Your brakes should be inspected twice a year if you do any heavy towing or hauling.) Make sure that your brake repair technician also keeps your metal on metal parts well lubricated to maintain an appropriate barrier between them and performs a general inspection of the overall condition of your brake fluid. Brake fluid can become contaminated with metal flakes and moisture that wear down essential braking components like calipers and wheel cylinders.
When problems do arise, it is best that you address your brake repair needs right away, before they get any worse.
