Among these safety components, brake systems play a pivotal role in ensuring the safety of both drivers and passengers. At the heart of every braking system lies a crucial component known as brake lining.

In this comprehensive guide, we will delve into the world of brake linings, exploring their types, importance, and essential care tips.

What is Brake Lining?

Brake linings are disposable friction materials attached to brake shoes or pads in a vehicle's braking system. When the brakes are applied, these linings press against the metal discs (rotors) or drums, creating friction.

This friction converts the car's motion energy (kinetic energy) into heat energy, which is what ultimately slows down or stops the vehicle.

Brake linings protect the underlying metal components from wear and tear caused by the heat and friction generated during braking.

They are essential parts of both disc and drum brake systems, used in everything from everyday cars to heavy-duty trucks.

Brake lining Replacement Time

Here's how to know when it's time for new ones:

  • Thickness check:

    Most linings need replacing when they get worn down to about the thickness of 2 stacked pennies (3-4 millimeters). Mechanics can check this during a routine service.

  • Eye check:

    Take a look at your brake linings yourself. Are they unevenly worn, cracked, or shiny? These are signs they need replacing, even if they're still kinda thick.

  • Noise:

    Do your brakes squeal or grind when you stop? Does the brake pedal feel soft and squishy? These sounds and sensations mean your linings might be worn out.

  • How you drive matters:

    If you drive a lot in stop-and-go traffic, haul heavy stuff, or like to brake hard, your linings will wear out faster. Aim to replace them every 50,000 miles, or more often if needed.

  • Check the manual:

    Your car's manual will tell you exactly how often to replace the brake linings. It's the safest bet to follow these guidelines.

Conclusion

Brake linings may be a small component in the vast machinery of an automobile, but their significance cannot be overstated. As the linchpin in the braking system, they contribute directly to the safety, performance, and durability of a vehicle.

Commercial Truck Brakes: Essential Guide to Brake Pads

Newton's first law of motion explains that an object will not change its motion unless an external net force acts on it. When you're in a truck that weighs close to 35,000 pounds, you want to have the confidence that there is a force strong enough to stop it when in motion. The braking system is key to stopping any vehicle. Understanding brake pads is key to buying the right ones to fit your fleet's trucks. Make a mobile truck tire repair service part of your safety culture and ensure your fleet vehicles have high quality, optimally functioning brake pads at all times. 

Types of Brake Pads

Brake pads absorb the kinetic energy of the wheels and create friction against the rotors, which slows or stops the wheel's rotations, allowing drivers to control the vehicle. Thus, it's important that brake pads are in top condition and capable of doing their job to the highest level of safety.

There are several types of materials that brake pads are made of:

  1. Organic Brake Pads ' Made of a blend of organic materials, such as rubber, glass or Kevlar, these brake pads are made for everyday driving. They won't generate a lot of brake dust and don't produce a lot of noise, but they will wear out faster than some other materials. They aren't suitable for heavy-duty trucks.
  2. Semi-Metallic Brake Pads ' These pads contain both organic materials and metal fibers, like steel or copper. These brake pads have good stopping power over organic pads, but they'll be noisier and may wear the brake rotors out faster. These brake pads are preferred for heavy tow loads or steep terrains.
  3. Ceramic Brake Pads ' Made of ceramic compounds and copper fibers, ceramic brake pads have a longer life than organic or semi-metallic pads. They can be more expensive, but they also have excellent stopping power. You can use these pads for urban traffic, or steep terrains or heavy tow-loads.
  4. Low-Metallic Brake Pads ' These brake pads are better than organic brake pads, because they contain both organic materials and metal fibers, but they do generate more noise and dust. They are an affordable option over ceramic brake pads.

How Often Should You Replace Brake Pads?

Truck brake pads have a wear rating, which should give you an idea of when they will need to be replaced. Most brake pads last about 40,000 miles, but it can depend on where and how the truck is driven. Train your drivers to inspect the brakes on their trucks before each journey and know what signs of wear to watch for. In addition to visual inspections, when brake pads start to wear down, drivers may notice a reduced braking response or hear grinding noises when braking. Sometimes they may also experience vibrations when braking. Regular vehicle maintenance by your commercial truck service will help your team keep fleet trucks in the best shape.

Brake Pad Maintenance Is Critical to Safety

Commercial trucks are the heaviest vehicles on the road. It's vital to everyone's safety that truck brakes and brake pads are well-maintained so that the vehicle's stopping power isn't impacted.
