The vehicle’s brake system is one of the most important safety features of a car. It converts the vehicle’s kinetic energy into heat to bring it to a stop. The proper functioning of this system is critical to your safety.
Long before a warning light signals a problem, your brakes provide tactile cues you can observe to know if there is a potential issue in the brakes.
Decoding the Sounds of Brake Trouble
Of the 6,829 North American vehicles inspected during the Commercial Vehicle Safety Alliance’s Brake Safety Day, as many as 11.3% failed the brake-focused vehicle inspection. As such, it’s good practice to always keep an eye or an ear out for potential brake issues. Here are some of the sounds you can hear when your brakes are faulty.
1. The Deep Growl or Grinding Noise
When you hear a harsh and grating sound, it indicates a critical safety and mechanical issue in the brakes. The brake pads might have worn down or the friction material might have been completely depleted. This results in a significant reduction of the car’s stopping power. It also damages the rotors, leading to costly repairs.
2. The High-Pitched Squeal
A sharp and high-frequency sound usually indicates significant wear on the brake, produced by a small metal tab that is attached to the brake pad. This sound happens when the pad’s material wears down to the minimum safe thickness. Controlling the temperature of the brakes and their components is essential to preventing this sound.
3. Rhythmic Clicking or Ticking While Braking
A clicking noise suggests a more localized issue with the brakes. Loose hardware or a foreign object in between the pad and the rotor might cause this clicking sound. In other cases, it might be caused by a damaged rotor.
Physical Sensations That Signal a Problem
Beyond sounds, here are some tactile telltale signs of a problem with your brakes.
1. A Spongy Pedal or Increased Stopping Distance
A soft or spongy brake pedal usually indicates a problem with the hydraulic system. After all, brake systems require non-compressible fluid to transfer force. Air or moisture might have entered the brake lines, causing the spongy feeling. This issue might be caused by a hose leak, a failing seal in the master cylinder or contaminated fluid.
2. Vibrations or Pulsating Through the Pedal or Steering Wheel
A classic sign of a warped brake rotor is feeling rhythmic pulses in the brake pedal. Rotors might warp due to overheating from repetitive, heavy braking and uneven cooling. This is a common issue when you’re frequently driving on mountain roads. The deformed metal surface of the rotors causes the brake pads to grab and release.
3. Your Vehicle Pulls to One Side When Braking
If your vehicle constantly veers to the left or the right when you’re braking, it signals a dangerous imbalance in the brake system. The brake caliper might be stuck, so it’s not applying or releasing the proper amount of pressure. It can also be due to a brake hose that prevents the fluid from reaching one of the calipers. As a result, one side of the vehicle brakes harder than the other, causing the vehicle to pull in that direction.
Your Action Plan for Faulty Brakes
As a car collector and an enthusiast, you might be well-equipped to perform standard brake operations, such as replacing worn pads and rotors. These tasks are safe to do yourself. However, it’s important to leave more complex systems to professionals. Any issue involving the hydraulic system requires specialized tools and a high degree of precision. Any error might cause a soft pedal or brake failure, thereby endangering your vehicle and your life.
There were 42,514 vehicle-related traffic fatalities in 2022. Choosing a competent mechanic improves your safety and provides you with peace of mind when driving. Make sure to partner with technicians certified by the National Institute for Automotive Service Excellence. This third-party certification ensures that the mechanic is sufficiently knowledgeable and competent for the job.
Make Brake Health Your First Priority
All the squeals, vibrations and pulls you experience are direct signals that something is wrong with your brakes. You need to act urgently to identify and fix the issue before it snowballs into a larger problem or endangers your life. Proactive car maintenance is crucial to ensure your vehicle’s safety and reliability.
