Brake Pads Explained: Types, Uses & How to Maintain Them

Brake pads are one of the most important components of your car because they not only provide safety but are responsible for complete control of the brake system while driving. Here in the UAE, the roads are diverse, from smooth highways to bustling streets. Therefore, smooth car brakes are key. Even so, most people do not pay attention to their brake pads until there is some problem. Regular brake pad service, however, can help maintain optimal performance and extend the life of your braking system. So, getting acquainted with brake types, their features, and brake pad maintenance can extend the life and the performance of your vehicle. In this comprehensive guide, we will help you learn about the types of brake pads, their functions, their unique features, and maintenance tips.

What are Brake Pads?

Brake pads are friction components in a disc braking system that create the force to slow down or stop your car when needed. When the brake pedal is pressed, the brake pads clamp onto the brake disc (rotor), generating friction to reduce the rotation of the wheels. Over time, brake pads wear out and require regular brake pad service for better braking efficiency and safety.

Types of Brake Pads

Brake pads are available in several different kinds, each made with unique materials chosen to find the right mix of effectiveness, how quietly they operate, and how long they last. The main types of brake pads are organic, semi-metallic, and ceramic, and each one is best for particular driving situations. 

1. Organic Brake Pads

These are made from materials such as glass, Kevlar, rubber and carbon and are softer and quieter but wear out faster. They are best suited for lightweight and city-driving vehicles.

2. Semi-Metallic Brake Pads

These brake pads are made from a blend of metal fibres and resin. They are a good choice because they dissipate heat well and last longer. You will get better stopping power with these, but they can be a bit louder and might wear down your rotors fast.

3. Ceramic Brake Pads

These pads are built from ceramic fibres and other non-metallic materials. They are known for providing excellent braking power and a longer lifespan, and they operate quietly. The downside is that they come with a higher price tag and are not as effective when it is extremely cold.

4. Low-metallic NAO Brake Pads

These brake pads have extra metal ingredients, like copper or steel, mixed in and help with better heat transfer and improved braking. However, they tend to create more brake dust and can be noisier than other options.

How do Brake Pads Work?

Brake pads work by converting kinetic energy into heat by generating friction. When brake pedals are pressed, hydraulic pressure forces the brake calliper to compress the pads against the rotor. Now, this friction slows down the wheels, finally halting your car. However, the material of brake pads, their heat resistance, and their wear rate affect the overall braking performance of your car.

How Brake Pads Affect Car Performance and Safety

The condition and quality of your brake pads directly impact the braking efficiency, stopping distance, and safety. Worn-out or poor-quality brake pads may result in:

• Increased stopping distance

• Reduced braking response

• Potential brake failure

• Damage to brake rotors

• Increased risk of accidents

Therefore, it is always recommended to opt for the right brake pads, schedule regular brake pad service, and replace them periodically to ensure improved performance of your car and enhanced road safety.

Signs Your Brake Pads Need Replacement

Catching early warning signs of brake pad wear and tear can prevent costly repairs and accidents. So, consider scheduling a brake pad service when the following common signs appear:

1. Abnormal Noise

High-pitched noises while applying brakes mean the pads are partially or fully worn out, and metal is rubbing against metal.

2. Reduced Braking Performance

If the brakes feel less responsive or require more pressure to stop, it’s time for a proper brake system checkup.

3. Vibration in the Brake Pedal

Twisted rotors due to worn-out brake pads can cause vibrations during braking.

4. Warning Light on the Dashboard

Some vehicles have brake pad wear sensors that trigger a warning light when brake pad replacement is required.

Maintenance Tips for Brake Pads

Brake pad service undoubtedly extends the life of brake pads and increases your car’s safety. Here are some important tips when you are considering brake pad maintenance:

1. Regular Inspections

Get the brake pads checked every 10,000-15,000 Kilometers or during routine car servicing.

2. Avoid Hard Braking

Frequent harsh braking accelerates wear; instead, practice smooth vehicle slowdown.

3. Keep Brake Fluid Clean

Dirty brake fluid can impact hydraulic pressure and pad performance. So, change brake fluids periodically or as and when needed.

4. Rotate tyres regularly

Even tyre wear distributes braking force more evenly, reducing stress on the pads.

5. Replace Pads in Pairs

Always replace brake pads on both sides to maintain balance and prevent uneven braking.

Brake Pads & Strange Sounds: When to Worry

Unusual noises while applying brakes are telling you about some underlying problems. Here is what different sounds may signify:

1. Squealing or Squeaking Noise

These noises come from worn-out pads due to overheating.

2. Clicking Noise

This noise comes from loose brake pads or their improper installation.

3. Grinding Noise

This noise indicates complete pad wear, exposing the rotor metal. This requires an immediate brake pad replacement.

4. Thumping Noise

A thumping noise comes from when the rotors are affecting brake pad contact. 

Therefore, addressing these abnormal sounds on a priority basis with timely brake pad service prevents further damage and allows you a smooth braking experience.

How to Choose the Right Brake Pads

Selecting the right brake pads depends on your driving needs, vehicle type, and budget. Consider the following:

1. Driving Conditions

For city driving, organic or ceramic pads work well; for high-performance or towing vehicles, semi-metallic pads are recommended.

2. Brake Pad Longevity

Ceramic pads last longer but cost more, while organic pads wear faster but are budget-friendly.

3. Noise and Dust Levels

If you want quieter and cleaner brakes, then ceramic pads are the best option for you.

4. OEM vs Aftermarket Pads

Original Equipment Manufacturer (OEM) pads provide compatibility, whereas aftermarket pads offer more variety and pricing options. So, the decision is up to you!

DIY vs Professional Brake Pad Replacement

Replacing brake pads is a doable DIY task for those with mechanical experience, but professional installations are more accurate and safe. Therefore, incorporating proper brake pad services into your car maintenance routine not only boosts efficiency but also extends the lifespan of the whole braking unit. Here are some pros and cons of DIY vs professional brake pad replacement procedure:

1. DIY Brake Pads Replacement Pros:

• Cost-effective

• Hands-on knowledge of your vehicle

• Convenience of scheduling

2. DIY Brake Pads Replacement Cons:

• Requires proper tools and expertise

• Risk of incorrect installation

• No professional warranty

3. Professional Brake Pads Replacement Pros:

• Expert installation with guaranteed quality

• Inspection of related braking components

• Safety assurance

4. Professional Brake Pads Replacement Cons:

• Higher labour costs

• Scheduling and waiting times

If you are comfortable with DIY automotive work, then DIY brake pad replacement can save money. However, if you are unsure, opt for a professional brake pad service.

Conclusion

Brake pads are necessary for your car, and understanding their types, functions, and proper maintenance practices can help extend their lifespan. Regular inspections, timely brake pad service, and choosing the right brake pads for your driving needs are some factors that you need to consider. However, over time, brake pads naturally wear down and eventually need to be swapped out to ensure your brakes work effectively. Whether choosing a DIY approach or a professional brake pad maintenance service, you can not ignore the safety of your car. Thus, choose from a variety of brake pads based on your needs and budget.
