5 Reasons Why Your Car Brakes Might Be Stuck (And What To Do)

A car's braking system is arguably its most important safety feature. Without functional brakes, a car becomes a dangerous projectile. But what causes brakes to get stuck? Understanding the reasons behind this issue can help you recognize potential problems and take necessary steps to ensure your safety on the road.

Corrosion

Exposure to dust, mud, and rain can lead to corrosion on brake components. This can also be exacerbated by heat from sunlight. As a result, brakes become harder to move and might feel stiff. Corrosion can also create a "vapor lock" condition where air gets trapped in the brake system, compounding the issue.

Long Periods of Inactivity

Cars that are rarely used can also experience brake problems. Temperature fluctuations can cause brake components, especially rotors, to corrode. Additionally, old brake fluid loses its boiling point, potentially impairing brake performance.

Worn-Out Brake Pads

Just like other car components, brake pads have a finite lifespan. Over time, the rubber seals in the brake system can harden, making it difficult for the pistons to retract fully.

Overly Tight Brake Adjustment

Brakes need adequate space to move freely. Adjusting brakes too tightly can create excessive friction, leading to a stuck brake.

Worn-Out Brake Pads

Worn-out brake pads can compromise brake effectiveness and even cause them to stick. Thin brake pads can lead to direct metal-to-metal contact between the brake pads and rotors, generating a squeaking or hissing sound.

Why should you avoid adjusting brakes too tightly?

Brakes need adequate space to move freely. Adjusting brakes too tightly can create excessive friction, leading to a stuck brake.

How does brake fluid affect brake performance?

Old brake fluid loses its boiling point, potentially impairing brake performance.

How does prolonged inactivity affect car brakes?

Cars that are rarely used can also experience brake problems. Temperature fluctuations can cause brake components, especially rotors, to corrode. Additionally, old brake fluid loses its boiling point, potentially impairing brake performance.

Taking Action

If you experience brake issues like stiffness or a complete lock-up, don't delay. Consult a trusted mechanic to diagnose and repair any damaged components. Your car's braking system is vital for safety. Don't ignore brake problems – seek immediate professional assistance.
