Why Are My Truck Brakes Squeaking? Causes and Solutions

“There’s a time for everything, and a reason for every belief.” In Vietnamese culture, especially among long-haul truck drivers, spiritual beliefs are deeply rooted. A new truck often requires a blessing ceremony and lucky charms. But what if, after some time, your beloved truck starts making strange noises, like a squeaking brake? Does it signify a bad omen? Don’t worry! This article will decode the mystery behind that annoying squeak and provide effective solutions.

1. Squeaking Brakes – A Sign of Trouble?

Squeaking brakes are not just annoying; they can also indicate potential problems within your braking system. Let’s diagnose your truck’s issue by exploring some common causes:

1.1. Worn Brake Pads

This is the most common reason for squeaky brakes. When brake pads wear down to their limit, the metal backing plates rub directly against the brake rotor, creating a high-pitched squeal. If you’re driving a 5-ton Dongfeng truck on Lang Ha Street and hear a squeak every time you brake, inspect your brake pads immediately.

1.2. Low-Quality Brake Pads

Using low-quality or counterfeit brake pads can also lead to squeaking. These pads often contain impurities, wear down quickly, produce annoying noises, and reduce braking efficiency.

1.3. Worn or Warped Brake Rotors

Like brake pads, rotors have a limited lifespan. Continuous braking, especially when carrying heavy loads, can cause rotors to wear down or warp, creating an uneven surface that rubs against the pads and produces a squeak.

1.4. Low Brake Fluid

Brake fluid plays a crucial role in transmitting braking force from the pedal to the wheels. Low brake fluid reduces braking performance, causing squeaking and even brake failure.

1.5. Other Causes

Other reasons for squeaky brakes include: dust and debris on the brake pads, loose caliper bolts, or a seized brake caliper piston.
