When To Replace The Pads In Your Disk Brakes

Did you know that brake pads can last anywhere from 65,000 to 100,000 kilometres? It depends on how you drive and how often you use your brakes. This range shows how important it is to know when to get new brake pads, especially if you hear them squeaking or rattling. 

Your car’s brakes are a complex system. Brake pads are at the centre, helping slow and stop your car, and they will need to be replaced periodically. Regular checks make sure they work well, keeping you and others safe.

In Canada, the winter weather can be tough, making it even more important to watch your brake pads. Winter driving can wear them down faster. So, knowing when to replace them is crucial.

In this post we’ll talk about warning signs, measuring pad life, and what affects wear. By the end, you’ll know how to keep your brakes in excellent shape.

Key Takeaways

  • Brake pads typically last between 65,000 and 100,000 kilometres.
  • Regular brake system servicing is crucial for safety.
  • Canadian weather can accelerate brake pad wear.
  • Understanding warning signs helps prevent brake failure.
  • Proper maintenance, including checking brake fluid levels, extends the life of your braking. system and reduces the need to replace your pads.

Understanding Disk Brake Pads and Their Function

Disc brake pads are an essential component of your car’s brake system. They help stop your car by rubbing against the rotor. This action slows down your vehicle when you press the brake pedal, but if you notice issues, you may need to replace your pads.

What Are Disk Brake Pads Made Of?

Disk brake pads feature a friction material on a metal plate. The materials used can change how well they work:

  • Organic pads: Quieter braking and sharp initial response
  • Sintered brake pads are known for their durability but may still need to be replaced after extensive use. Pads are durable and perform well in wet conditions.
  • Semi-metallic pads: Balance stopping power and durability

How Disk Brakes Work

When you press the brakes, the pads rub against the rotor. This creates friction, which slows your car. 

When To Replace The Pads In Your Disk Brakes

It’s important to know when to replace your disc brake pads. The life of brake pads changes based on how you drive.

City drivers might need new pads every 65,000–75,000 kilometres. But those who drive on highways can go up to 100,000 kilometres or more without needing a change.

Check the brake pads by looking at the friction material. If it’s less than 3mm inch thick, it’s time for a brake check. Some cars have dashboard lights that indicate pad replacement when the thickness reaches 1mm.

Listen for strange sounds when you brake. Squealing means the pads are wearing out. Grinding sounds mean they’re very worn and may indicate the backing plate is contacting the brake rotor.

Common Warning Signs for Worn Brake Pads

It’s important to know the signs of worn brake pads for your safety. Let’s look at the main signs that mean it’s time to replace your brake pads.

Squealing and Screeching Sounds

When you brake, a high-pitched squeal or screech is a clear sign you need new pads. This noise comes from wear indicators. These small metal tabs come into contact with the rotor. If you hear this, it’s time to check your brakes.

Grinding, Noises, and Vibrations

Grinding sounds during braking are a serious warning sign. This indicates that your brake pads have worn down to the point of metal-to-metal contact. You may also experience vibrations or pulsations in the brake pedal, which could indicate uneven wear or warped rotors.

Reduced Braking Performance

Worn brake pads increase the vehicle stopping distance. You might notice longer stops or a softer pedal. If you need to press harder to stop, it’s time for a brake check, as your pads may need to be replaced.

Visual Indicators of Wear

Checking your brakes visually can help catch wear early, potentially preventing the need to replace your pads. New pads are about 12 mm thick. Replace them when they reach a thickness of 3 or 4 mm. Some cars also feature lights on the dashboard for replacing thin pads, which can help prevent the backing plate from contaminating the brake rotor.

Measuring Brake Pad Life and Thickness.

Knowing how thick your brake pads are is key to keeping you safe. 

Understanding Brake Pad Thickness Standards

Most vehicle manufacturers recommend replacing pads  when they reach a thickness of 3 mm or less.

How to Measure Your Brake Pads

To check your brake pads, remove the wheel. Look at the friction material. If the friction material is less than 3mm, it’s time for a replacement. Some cars let you check through the wheel spokes, making it easier.

Using Wear Indicators

Wear indicators are commonly found on the brake pads of many cars. These make a squealing sound when the pads are 3 mm thick. Some cars even have electronic sensors that light up a dashboard warning light when the pads are too thin.

Checking your brake pads regularly is important. It helps you catch wear before it’s a safety risk

Factors affecting brake pad wear

Many factors determine the life of your brake pads. How you drive is key. Hard braking or lots of stops means you’ll need new pads sooner.

On average, pads last about 75,000 kilometres. However, this can vary significantly depending on your driving style and the location of your vehicle.

Driving in the city wears brake pads faster than driving on the highway. Driving in mountains also makes pads wear out quicker. Additionally, a heavy car puts more stress on your brakes.

Observing a significant amount of brake dust on your wheels indicates a potential problem. It might be time for a brake check. The quality of your brake pads, especially metallic ones, also matters. Better pads last longer and work better.

FactorImpact on Brake Pad Wear
Urban DrivingIncreased wear due to frequent stops can lead to the need to replace your pads.
Highway DrivingThere is less wear because there are fewer brake applications.
Mountainous TerrainAccelerated wear due to increased braking
Vehicle WeightHeavier vehicles cause faster wear.
Pad QualityHigher quality pads typically last longer.

To make your brake pads last longer, keep a safe distance from cars ahead. Anticipate what traffic will do. And, don’t ride your brakes. These tips can help your pads last longer, saving you money and keeping your brakes working well.

Conclusion

Keeping your car’s brakes in excellent shape is key for safety. Regular checks and upkeep can prevent expensive fixes and accidents. Always check your brake pads every 5,000 kilometres or five months, whichever is sooner.

Listen for squealing sounds, notice if your car brakes less well, or see wear signs. When your brake pads get to 3 mm thick, it’s time to replace them. Brake pads can last from 65,000 to 100,000 kilometres, depending on how you drive and your car’s type.

Brake pad replacement costs between $115 and $270 per axle. A full brake service, including rotors and calipers, can cost $500 to $1,200. Although it might seem expensive, quality parts and timely service can save you money in the long run and make your car run better.

Being proactive with brake care keeps your car safe, makes your brakes last longer, and gives you peace of mind. If you’re not sure about your brakes, book an appointment online or call us at Canadian Super Shop.
