Understanding Parking Brake Failures: What Every Bus Driver Should Know

When it comes to driving a bus in Ontario, understanding the mechanics of your vehicle just might be your greatest ally. So, let’s talk about something you might not have given much thought to: the parking brake. Ever pondered why your parking brake might fail? Spoilers alert—one of the main culprits is simply forgetting to disengage it while driving!

What Really Causes Parking Brake Failure?

You might think, "Really? Driving with the parking brake on?" Yes! It sounds like something that shouldn't happen, but it's surprisingly common. The act of driving with the parking brake engaged can lead to major issues. This typically wears down the brake pads quicker than you can say "brake failure." Not only that, but it can harm your overall brake system, leading to potentially dangerous situations.

So, the real kicker here? While driving with that pesky brake still on may be the most common issue, we can't ignore some other possible factors that can come into play. Lack of maintenance is another point here—if you let your brakes go unchecked, you might just be asking for trouble. But don’t get it twisted; it’s not the prominent factor in failed parking brakes.

It’s Not Just About Preventing Failure

Maintaining your bus’s parking brake isn’t just about preventing disaster on the road; it’s also about ensuring the smoothness of operation. That means you should be regularly inspecting cables and fluid levels. Yes, rusty cables and fluid leaks are also contributors to parking brake failure. But seriously, how often are you going to experience fluid leakage compared to the far more common scenario of forgetting to disengage the parking brake?
