If you notice that your heavy-duty truck is making a strange noise when you press the brakes, it is important to address this issue as soon as possible. It may not be much of a concern if you only notice it happening once, however, if the noise occurs often it is a sign that brake repair is necessary. It is essential for any truck to have properly functioning brakes, as they play a crucial role in ensuring the safety of the driver while on the road. Here are some warning signs that your truck may need its brakes examined at a nearby diesel repair shop:
How are air brakes operated?
Before we get into the signs that your truck needs brake repair, let’s first understand how heavy-duty truck brakes work. The majority of heavy-duty trucks use a three-part braking system. Parking brakes, emergency brakes, and air brakes. The whole system is well-designed and operates perfectly in the majority of situations. The air within the truck's tank is compressed by friction applied to the brake pad, and as a result, pressure is applied to the brake pad by a piston. Parking brakes, another system component, help prevent the truck from while it is parked, thus the name. As one may think, large equipment like large trucks and trailers also require emergency brakes. Some trucks even feature automated emergency brakes, while others need human engagement.
Five indicators that your heavy-duty truck brakes need repair
1. Brake warning light appears on your dash
It's time to get your brakes examined if the red brake warning light illuminates. It is one of the most obvious signs that your brakes need immediate inspection and maintenance. Even though you may not believe that your truck's brakes might be having any difficulties, disregarding this warning sign could eventually result in more severe complications. Bring your truck to a nearby repair shop for a quick checkup if you notice the brake warning light is on.
2. Squealing sound
If you hear a screeching sound when you use the brakes, it is another sign that something is wrong. This often means that your brake pads are malfunctioning and likely need to be replaced. If you hear this noise, take the time to get your brake pads changed immediately. If you wait too long, you risk damaging your rotors and needing a far more costly repair.
3. Braking-related vibration
Braking vibrations are often a sign of warped rotors. Rotors are the name for the enormous silver discs that are located behind your wheel. Your truck comes to a stop when you use the brakes because the brake pads apply pressure to the rotor. Your braking system is compromised by warped rotors, which is why you feel these vibrations when stopping. Bring your truck to your diesel repair shop for a thorough inspection and repair if you experience these sensations during braking.
4. Fluid leaks
There are several potential causes of leaking brake fluid in heavy-duty trucks. Some common causes include:
- Worn or damaged brake hoses: If the brake hoses are worn or damaged, they can develop leaks, which can cause brake fluid to leak out of the system.
- Loose fittings or connections: If the fittings or connections in the brake system are loose, they can cause leaks. This can be caused by wear and tear or by improper installation.
- Corrosion: Corrosion can weaken the components of the brake system and cause them to develop leaks. This is more likely to occur in older vehicles or in areas with harsh weather conditions.
- Failed seals: The seals in the brake system can fail over time, which can cause brake fluid to leak out.
- Faulty brake components: If any of the components in the brake system are faulty or malfunctioning, they can cause leaks. This can include issues with the brake master cylinder, brake calipers, or brake pads.
If you notice that your heavy-duty truck is leaking brake fluid, it is important to have it checked by a mechanic as soon as possible to determine the cause and have it repaired. Brake fluid leaks can compromise the safety and performance of your vehicle, so it is important to address them promptly.
5. A burning smell
If your brakes have overheated and you can smell burning coming from your wheels and brakes, you should stop driving immediately to avoid complete braking failure. Pull over and check your brakes as soon as you see any smoke or smell any odor emanating from them. After that, speak with your technician to determine what to do next.
If your brakes fail, what should you do?
The weight of heavy-duty trucks varies from 35,000 to 80,000 pounds, and that much weight must be stopped once it begins to roll, necessitating the use of heavy-duty braking systems. When a truck's braking system is damaged, ineffective, or worn out, everyone on the road is in danger. Drivers must thus be aware of possible braking issues and the warning signs to look for to prevent them.
For a truck driver, nothing is scarier than being unable to stop their truck because the brakes aren't working. Experienced drivers may employ the following tactics to allay their worries and keep both themselves and other road users safe:
- Downshift to reduce speed
- Engage the emergency brake
- Activating the brakes (if hydraulic)
- Seek a way out (another lane or shoulder of the road)
- Use a ramp for emergency stopping
Maintaining the brakes on your heavy-duty truck is an essential part of ensuring the safety and reliability of your vehicle. Properly functioning brakes are necessary for the safe operation of the truck and are crucial for avoiding accidents and ensuring the safety of the driver and other motorists on the road. Failing to properly maintain the brakes on your heavy-duty truck can lead to issues such as reduced braking performance, increased braking distance, and even complete brake failure, which can be extremely dangerous. Regular maintenance and inspections of the brakes can help to identify and address any issues before they become serious problems, ensuring the continued safety and performance of your vehicle.
