Summer is the perfect time for road trips, scenic drives, and outdoor adventures. However, after a long day on the road, you might notice that your car’s brakes feel different—specifically, spongy. Understanding why this happens can help you address the issue promptly and ensure your vehicle remains safe to drive. At Joe’s General Auto, your trusted local auto repair shop, we want to help you understand what might be going on with your brakes after those summer excursions.
What Causes Spongy Brakes?
Spongy brakes are often a sign that something in the braking system needs attention. Here are the most common reasons why your brakes might feel less responsive after a long summer drive:
1. Brake Fluid Issues
- Heat Expansion: During long drives, especially in the summer heat, brake fluid can expand. This expansion can lead to air bubbles forming in the brake lines, which in turn causes the brakes to feel spongy or soft when pressed.
- Moisture Contamination: Brake fluid is hygroscopic, meaning it can absorb moisture from the air. In high humidity, this can be accelerated, leading to a decrease in the boiling point of the brake fluid and causing a spongy feeling.
2. Brake Pad Wear
- Overheating: Long drives can cause brake pads to overheat, especially if you are frequently braking on hilly or mountainous terrain. This overheating can lead to glazing—a condition where the surface of the brake pads becomes smooth, reducing their effectiveness.
- Worn Pads: If your brake pads are already thin, the added stress from a long drive can exacerbate wear, making the brakes feel less responsive.
3. Air in the Brake Lines
- Long Drives and Vibration: The vibrations from long trips, especially over rough or uneven roads, can sometimes cause air to enter the brake lines. This is particularly likely if the brake system has not been bled in a while.
4. Caliper Issues
- Caliper Sticking: The heat from prolonged driving can cause the brake calipers to stick, which affects the brake fluid’s ability to transfer force evenly. This sticking results in a spongy brake pedal.
How to Address Spongy Brakes
Recognizing the signs of spongy brakes is important for maintaining your vehicle’s safety. Here’s what you can do:
Inspect and Maintain Your Brake System
- Regular Brake Fluid Check: Ensure your brake fluid is at the recommended level and has not absorbed excess moisture. If needed, have it replaced.
- Brake Pad Inspection: Regularly check the thickness of your brake pads. If they’re worn, replace them before they cause further issues.
- Bleed the Brake Lines: If air has entered the brake lines, bleeding the brakes can remove it and restore proper brake function.
