Your Hyundai Sonata's superior stopping power is made possible by the collective effort of your vehicle's top-notch brake system components. Each of these brake assembly parts has its own contributions in making your brake system more efficient. Take for instance your Hyundai Sonata brake pad shims. They are responsible for maintaining the smooth interaction between your brake pads and brake rotors. So when the brake pad shims fail, your vehicle's braking performance declines. For your awareness, here are the most common signs of Hyundai Sonata brake pad shim failure and the reasons behind them:
If you are experiencing too much shaking or vibration everytime you step on your Hyundai Sonata's brake pedal, it could be an indication that your vehicle's brake pad shims are broken or missing. Your Hyundai Sonata brake pad shims have the tendency to fall out from the caliper and the rest of the brake assembly, especially when you change your brake pads. Since these braking components are often made of rubber or metal, brake pad shims are also bound to deteriorate. Rubber shims tend to wear out over time, while metal shims accumulate rust and eventually corrode. In these cases, replacing the lost or damaged brake pad shims is the only solution.
Does your Hyundai Sonata squeal like a pig everytime you hit the brakes? If you are nodding your head in agreement right now, your brake pad shims are probably in bad shape. Although the level of brake assembly noise usually depends on the brake pad material used, it is also possible for the shims to cause these squealing and squeaking noises. When your Hyundai Sonata brake pad shims go bad, their efficiency in maintaining the perfect fit between the brake pads and the brake rotors decreases. These discrepancies will then allow the pads and the rotors to loosely hit each other, producing the loud and annoying squealing noises as you stop the vehicle. To avoid the embarrassment caused by noisy brakes, have your damaged shims replaced as soon as possible.
Premature brake pad or brake rotor wear can also be a sign of brake pad shim failure. So if you are forced to replace your pads and rotors more often than normal, you may want to check your shims for damage. Other signs of Hyundai Sonata brake pad shim failure that you need to watch out for include decrease in braking efficiency and brake pads that won't stay in place.
