5 Symptoms of a Brake Problem that You Shouldn’t Ignore

Interstate Automotive • November 19, 2024

Your vehicle’s braking system is crucial for safe driving, and when it begins to show signs of trouble, it's essential to address them quickly. Ignoring brake problems can lead to costly repairs, or worse, put you and others on the road at risk. At Interstate Automotive, we provide expert brake repair in the greater Olympia, WA area. Here are five common signs of a brake issue that mean it's time to visit the mechanic.

Squeaking or Squealing Noises

One of the first signs of a brake problem is a high-pitched squeaking or squealing noise when you apply the brakes. This is often caused by a worn-down brake pad, which includes a small metal indicator designed to create this noise as a warning.

Grinding Sounds

If you hear a grinding noise when you press the brake pedal, it’s typically a sign that your brake pads have completely worn away, and the metal parts of the brakes are now rubbing against each other. This not only reduces braking efficiency, but can also damage the rotors, leading to more costly repairs. Grinding sounds should be addressed immediately to prevent further damage.

Vibrations when Braking

When you press the brake pedal and feel a vibrating or shaking sensation, it often points to warped rotors. Warped rotors create an uneven surface, causing the brakes to pulse when you slow down. This vibration can affect your control over the vehicle, so having the rotors resurfaced or replaced will help ensure smooth and safe braking.

Soft or Spongy Brake Pedal

A soft or spongy brake pedal, one that sinks closer to the floor when pressed, can indicate an issue with the brake fluid or the brake lines. This can happen if air gets into the brake lines or if there’s a leak in the brake fluid system. Without sufficient fluid pressure, your brakes won’t be as effective. This is a serious safety concern and should be checked immediately by a professional.

Car Pulls to One Side When Braking

If your car pulls to one side when you apply the brakes, it may be due to a stuck caliper. A vehicle that doesn’t stop in a straight line can be difficult to control and increases your risk of an accident, making it important to address this issue ASAP.

5 Warning Signs that It’s Time for Alternator Replacement

By Interstate Automotive • November 21, 2025

Your vehicle’s alternator plays a crucial role in keeping the electrical system running smoothly. It charges the battery and powers essential components like the headlights, dashboard lights, and power windows while the engine is running. When the alternator begins to fail, your car can quickly experience electrical issues and even lose power completely. At Interstate Automotive, we provide expert alternator replacement and auto electric repair in the greater Olympia area. Here are five common signs that it may be time to replace your alternator. Problems with Lights One of the most common signs of a failing alternator is dim or flickering lights. You might notice your headlights or dashboard lights growing noticeably weaker. Since the alternator powers your vehicle’s lighting system, inconsistent brightness often points to irregular power output. Weak or Dead Battery While batteries can wear out on their own, a weak or frequently dead battery can also be a symptom of a failing alternator. If you’ve replaced your battery recently but it continues to lose charge, your alternator may be the real problem. The mechanic can test your charging system to confirm whether the alternator is functioning properly. Unusual Sounds Under the Hood A failing alternator can produce unusual noises that indicate trouble. Grinding or whining sounds may come from a worn-out bearing or a belt issue in the alternator. Having the alternator inspected at the first sign of unusual noise can potentially prevent bigger problems. Warning Light on the Dashboard Modern vehicles often feature a dashboard warning light shaped like a battery or labeled ALT or GEN. When this light turns on, it’s a signal that your charging system isn’t working correctly. While this warning could indicate a battery problem, it frequently points to a malfunctioning alternator. Don’t ignore the light—have your vehicle checked by a professional to diagnose the issue before it worsens. Electrical Accessories Malfunctioning If your power windows, radio, or air conditioning begin to behave erratically, it could be due to inconsistent power supply from a bad alternator. The alternator may not be generating enough electricity to support all systems, especially when demand is high. When multiple accessories start acting up at once, it’s a warning sign that your alternator is no longer keeping up with your vehicle’s electrical needs.

4 Signs that Your Car Needs Brake Repair Now

By Interstate Automotive • October 24, 2025

Your vehicle’s brakes are one of its most critical safety systems, and any issue with them should be taken seriously. When brakes start to fail, stopping distances increase, handling becomes unpredictable, and the risk of accidents rises dramatically. Recognizing early warning signs can help you avoid costlier repairs and stay safe on the road. At Interstate Automotive, we provide expert brake repair in the greater Olympia, WA area. If you notice any of the following symptoms, it’s time to schedule professional brake service immediately. Strange Noises Unusual sounds coming from your brakes are one of the most common indications of trouble. A high-pitched squealing noise usually means the brake pads have worn thin. If the sound is more of a harsh grinding, it could mean the pads are completely worn out, and metal is scraping against metal. Continuing to drive with grinding brakes can damage rotors, so prompt attention is essential. Soft Brake Pedal If your brake pedal feels soft, spongy, or sinks quickly toward the floor when pressed, that’s a warning sign of a problem in the hydraulic system. This may be due to air in the brake lines or a fluid leak. A soft pedal means your brakes aren’t generating proper pressure, putting you at serious risk if you need to stop suddenly. If your car is leaking brake fluid, it’s a major safety hazard and best to get towed to the shop. Vibrations When you press the brake pedal and feel vibrations or pulsing, it often indicates warped rotors. This can happen from excessive heat buildup and uneven wear. Pulsing brakes reduce stopping efficiency, so it’s best to have a technician diagnose and resolve the issue as soon as possible. Warning Light on the Dashboard If your brake warning light appears on the dashboard, it’s your car’s way of alerting you to a potential issue. Even if the brakes feel normal, an illuminated light should never be ignored. A technician can run diagnostics to determine the exact cause and prevent a small issue from becoming a major one.
