What Causes Brake Overheating in Vans?
Van brake systems are designed to handle greater loads and stress than regular car brakes, but they’re not invincible. One of the most common issues van drivers face is brake overheating, which can compromise braking performance, increase wear and tear, and even lead to brake failure if left unchecked.
At Andrews Car Centre in Lincoln, we specialize in diagnosing and repairing brake systems for all types of vans. In this article, we’ll explore the causes of brake overheating, how it affects your van, and what you can do to prevent it.
How Does Brake Overheating Occur?
When you press the brake pedal, the brake pads press against the brake discs (or drums), generating friction to slow the vehicle down. This friction produces heat, which is usually dispersed through the brake system.
However, under certain conditions, the heat generated can exceed the system’s ability to dissipate it, causing the brakes to overheat. This is known as brake fade, where the brakes lose effectiveness due to high temperatures.
Common Causes of Brake Overheating in Vans
1. Frequent Heavy Braking
Driving in urban areas or stop-and-go traffic requires constant braking. This frequent use prevents the brakes from cooling down between applications, causing a build-up of heat over time.
2. Carrying Heavy Loads
Vans often carry substantial cargo, which puts extra strain on the brake system. The heavier the load, the harder the brakes need to work to slow the vehicle, resulting in higher friction and heat production.
3. Long Descents
Driving downhill for extended periods requires continuous braking to control speed. This constant application of brakes leads to excessive heat build-up in the pads and discs.
4. Worn Brake Components
Worn brake pads or discs are less effective at dissipating heat, which can lead to faster overheating. Thin pads or grooved discs reduce the surface area available for heat dispersion.
5. Faulty Calipers or Sticking Brakes
If the brake calipers don’t release fully or the brake pads stick to the discs, the brakes will continue to generate friction even when you’re not pressing the pedal. This constant friction leads to overheating.
6. Poor Quality Brake Components
Using substandard or mismatched brake pads and discs can reduce the system’s ability to handle heat. Cheap materials often degrade more quickly under high temperatures.
7. Insufficient Brake Fluid Maintenance
Brake fluid absorbs moisture over time, which reduces its boiling point. In high-temperature conditions, this can cause the fluid to boil, leading to brake fade and reduced braking performance.
How Overheating Affects Your Van’s Brakes
Brake overheating can cause significant damage to your van’s braking system, including:
- Glazed Brake Pads: The surface of the pads hardens, reducing their ability to create friction.
- Warped Brake Discs: High temperatures can deform the discs, leading to vibrations and uneven braking.
- Brake Fluid Boiling: Air pockets form in the hydraulic system, causing a spongy brake pedal and reduced stopping power.
- Premature Wear: Overheated components wear out faster, leading to increased repair costs.
Warning Signs of Overheated Brakes
If your van’s brakes are overheating, you may notice:
- A burning smell near the wheels.
- Reduced braking performance or the feeling that the brakes aren’t responding as they should.
- Vibrations or pulsations when braking.
- A spongy brake pedal, indicating fluid issues.
- Squealing or grinding noises due to excessive pad wear or damaged discs.
How to Prevent Brake Overheating in Vans
1. Adjust Your Driving Style
- Avoid riding the brakes on long descents; instead, use engine braking by shifting to a lower gear.
- Maintain a safe following distance to minimize heavy or sudden braking.
2. Don’t Overload Your Van
- Stay within your vehicle’s load capacity to reduce strain on the brakes.
- Distribute cargo evenly to avoid putting too much pressure on one side of the brake system.
3. Use High-Quality Brake Components
- Invest in durable brake pads and discs designed for heavy-duty use, especially if you regularly carry heavy loads.
4. Schedule Regular Brake Maintenance
- Have your brakes inspected at least once a year or every 10,000 miles.
- Replace worn pads, discs, and brake fluid as needed.
5. Monitor Brake Fluid Levels
- Replace brake fluid every two to three years to prevent moisture build-up and maintain optimal performance.
