Your car’s brakes are arguably its most important safety feature, so it’s imperative that the components that make up your brake system are kept in tiptop shape and working optimally. If you experience any problem with your brakes, for your own safety, have those issues checked now rather than later, as faulty brakes can easily turn into a serious accident. Here are four common symptoms to watch out for.

Ear-Piercing Noises. When you hear squealing and screeching noises every time you step on the brakes, that’s a sign of excessive wear on your brake pads. Have your pads inspected and replaced immediately, as issues with your brake pads tend to spread to other parts, which can spell more expensive repairs for you.

Steering Wheel Vibration. A vibrating steering wheel when brakes are applied indicates that the surface of the rotor discs has become warped or uneven. Usually, the solution to this issue is to have your rotor discs resurfaced at a machine shop. However, if the machinist says your discs are a hopeless case, replace them.

Long Braking Distance. If it takes too long for your car to come to a full stop, there are two common reasons for this issue: One, your brake fluid might be leaking. Two, your tires maybe overly worn. If your tires are okay, check your brake system for leaks. Leaky or damaged pipes and hoses should be replaced.

Spongy Brake Pedal. A spongy brake pedal feel is another symptom of brake system leak. A brake system can leak either air or fluid. You can confirm a brake system leak if you observe fluids on the concrete underneath your engine or tires, or if you keep topping up your brake fluid, which you’re not supposed to be doing because it is a closed system.

Remember that you should replace rotor discs, brake pads, and tires in pairs. This means if you have to replace the left front tire, make sure to replace the right front tire as well. Replacing these items in pairs is necessary to make sure the vehicle is properly balanced and functioning safely.
