Organic vs sintered brake pads: Which type do you need?

Organic brake pads

Did you know that your choice of brake pads could mean the difference between a smooth stop and a costly brake failure? Choosing the wrong type of brake pad can lead to poor braking performance, excessive wear, and even safety risks. 

But with so many options on the market, how do you know which one is right for your vehicle? Don’t worry. This guide will break down the key differences between organic vs sintered brake pads. By the end, you’ll be able to make an informed decision that ensures optimal performance and safety.

Organic brake pads, often referred to as resin pads, are made from a blend of materials like Kevlar, rubber, and silica, all held together by resin. This combination creates a softer pad that provides a quieter braking experience and a smoother, more progressive feel when you hit the brakes.

They’re a great fit for recreational cyclists or for road cycling in dry weather. They’re also commonly used in mountain biking where extreme braking force isn’t necessary. Plus, they work wonderfully on bikes with polished or chrome-plated rotors, thanks to their gentle impact on the surface.

Sintered brake pads are a popular choice for riders looking for robust performance in challenging conditions. They’re made by sintering, which fuses metallic particles—like copper or iron—under high heat and pressure. This then results in a dense, durable pad.

This composition gives them an edge in durability. They also provide consistent performance, particularly in wet, muddy, or high-temperature situations, making them ideal for downhill and enduro mountain biking or aggressive riding styles.

Sintered vs organic brake pads: What are their key differences?

There are two common types of braking systems: drum and disc brakes. Between them, disc brakes are gaining popularity, especially in mountain biking and road cycling, because of their superior stopping power and control. However, using disc brakes also means choosing the right brake pads, as they create the friction needed to stop your wheels.

So, when it comes to choosing the best MTB brake pads, understanding the differences between sintered and organic brake pad types is crucial. Whether you’re considering motorcycle or bicycle brake pad types, we’ll dig into the key factors that’ll help you navigate this decision.

In terms of initial bite

Initial bite is the term used to describe how quickly a brake pad starts gripping the rotor. Organic brake pads shine in this area with their sharp and immediate response. They start working right away, giving riders excellent control, especially at lower speeds. This quick engagement also makes them ideal for casual cyclists who need fine modulation in braking.

On the other hand, sintered brake pads have a more gradual initial bite. They often need a short warm-up period to perform at their best. Once warmed up, they provide strong and consistent braking, although their response is not as immediate as that of organic pads.

In terms of braking performance

Braking performance refers to the overall stopping power of a brake pad. This aspect largely depends on the friction coefficient or how effectively the pad can grip the rotor. It’s also one of the areas measured during an MOT test in the UK.

Organic pads excel under dry conditions with their smooth, progressive braking. They offer excellent control at lower speeds. However, they can also fade quickly under high temperatures, which makes them less suitable for intense or prolonged braking scenarios, like in hilly terrain or during aggressive descents.

In contrast, sintered pads shine when the heat is on. They maintain consistent braking power even during strenuous riding, such as downhill mountain biking, where sustained pressure is common. Their durability and performance in wet or muddy conditions also make them a solid choice for varied environments, ensuring reliability in unpredictable weather. 

In terms of disc compatibility

When it comes to disc compatibility, organic brake pads are gentler on rotors. Their softer composition results in less wear, which can extend the lifespan of disc brake pads. They’re compatible with all disc types as well, including polished or chrome-plated rotors. This makes them a versatile option for road bikes and mountain bikes alike.

On the flip side, sintered brake pads are more abrasive and can lead to increased rotor wear over time. This wear is especially pronounced when paired with rotors not designed for harsher compositions. So, it’s important to match sintered pads with compatible rotors to avoid premature wear and damage.

Additionally, sintered pads transfer more heat to the disc, which can impact the rotor’s longevity and performance if not managed properly. This makes them better suited for more demanding conditions, but riders must ensure their rotors can tolerate this added stress. Balancing performance and rotor preservation is key for optimal braking in any biking scenario.

In terms of noise and vibration

Organic brake pads are notably quieter during braking, thanks to their softer material. They produce less noise, especially when cold or during light braking. Additionally, their design reduces vibration, resulting in a smoother and more comfortable experience.

Meanwhile, sintered brake pads tend to be louder. They produce a characteristic squeal or grinding noise, particularly when cold or during initial stops. Their harder composition can lead to increased vibration, too, especially under heavy braking. Furthermore, in wet or muddy conditions, sintered pads can generate more noise due to the metal particles interacting with moisture.

For those considering alternatives, semi-metallic brake pads sit between organic and sintered options. They offer decent noise reduction while providing slightly better performance than organic pads. However, riders should be aware that they may still not completely eliminate the noise common with sintered pads.

In terms of durability and wear resistance

When considering brake pad replacement, the differences between organic and sintered pads become quite clear in terms of durability.

Organic brake pads typically have a shorter lifespan because they’re made from softer materials that wear out faster, especially in tough conditions. They’re not ideal for harsh environments—like wet, muddy, or sandy terrain—where they degrade more quickly and are prone to glazing under high temperatures.

On the other hand, sintered pads are made from hard metallic materials that offer a longer lifespan and greater wear resistance. This makes them suitable for all weather conditions, from rain to heat, without compromising performance.

Some also compare organic vs metallic brake pads in terms of durability. However, as semi-metallic sintered pads combine the best of both worlds, it’s wise to consider them as a viable middle ground.

In terms of cost

Organic brake pads are typically cheaper, ranging from £7 to £25. This lower price reflects their quicker wear and shorter lifespan, though. While they might seem budget-friendly at first, frequent replacement can add up over time, particularly for active riders or those in tough conditions.

Sintered brake pads generally cost between £12 and £35. Although they require a larger upfront investment, their durability and longer lifespan can lead to savings in the long run. For serious cyclists who ride in demanding environments, spending a bit more initially can be worthwhile for reliability and performance gains.

It’s also wise to consider the costs of servicing a bike if you ever run into problems with your brakes. It’s better to invest in a higher-quality brake pad from the start than having to constantly replace or repair it.
