When checking your brakes, look, listen and feel. You should check your brakes when they are cold. First, check for wear by looking at your brake pads. If the brake pad has less than 3mm depth, they need replacing.
As for the discs, a thin layer of rust is common. But high-pitched screeching, grinding or growling noises are signs that your calliper and discs are rubbing together. If this is the case, you should get it checked out right away.
If your brakes are fading, becoming less responsive or if the pedal sinks, this could be a sign of a brake fluid leak. If your vehicle pulls to one side under braking, there may be a problem with your brake fluid. If you’re unsure, head to your local First Stop store and we’ll check them for free!
