Avid Elixir Brake Pad Guide

Understanding Your Avid Elixir Brake Pads

When it comes to reliable stopping power on your bicycle, your brake pads are absolutely crucial. For riders who rely on the performance of Avid Elixir hydraulic disc brakes, choosing the correct replacement pads is essential for maintaining optimal braking efficiency and safety. This guide will delve into the specifics of what brake pads fit Avid Elixir systems, offering a comprehensive overview for both seasoned mechanics and enthusiastic home tuners.

The Avid Elixir range has been a popular choice for many years, known for its consistent performance and relatively straightforward maintenance. However, like all wear items, brake pads eventually need replacing. The good news is that Avid has maintained a relatively consistent standard for their brake pad fitment across much of the Elixir line, simplifying the selection process. However, there can be subtle differences, and understanding these nuances will ensure you get the best possible performance and longevity from your braking system.

Avid Elixir Brake Pad Compatibility: The Core Information

The most common brake pads that fit the majority of Avid Elixir models (including Elixir R, Elixir CR, Elixir 5, Elixir 7, Elixir 9, and the XX series) are the standard SRAM Red / Avid Elixir organic and metallic pads. These are widely available from SRAM (the parent company of Avid) and numerous aftermarket manufacturers. When purchasing, you'll typically see them listed with compatibility for both SRAM road and Avid mountain bike brakes, which share the same caliper design for these specific models.

It is important to note that while the caliper shape is often the same, the backing plate material and compound can vary significantly between different pad types. These variations directly influence braking feel, power, modulation, and durability.

Types of Brake Pad Compounds:

The choice of brake pad compound is a critical decision that impacts your riding experience. For Avid Elixir brakes, you'll primarily encounter three main types:

Organic (Resin) Pads:

These pads feature a composite material with organic fibres (like kevlar, aramid, or carbon fibres) bonded with resin. They offer excellent initial bite and quiet operation, especially in dry conditions. They also tend to bed in faster. However, they generally wear out quicker than metallic pads and can be more susceptible to performance degradation in wet or muddy conditions.

Metallic (Sintered) Pads:

Metallic pads are made by sintering (fusing at high temperatures) metallic particles, such as copper or steel, often with additives. They provide superior stopping power and are much more durable, especially in wet, muddy, or high-temperature environments. The trade-off is that they can be noisier, take longer to bed in, and may cause slightly more rotor wear.

Semi-Metallic Pads:

As the name suggests, these are a hybrid, combining organic fibres with metallic particles. They aim to offer a balance between the quiet performance and initial bite of organic pads and the durability and power of metallic pads. They are a popular choice for riders seeking a versatile all-around pad.

Identifying Your Specific Avid Elixir Model

While the general compatibility is high, it's always wise to confirm the exact model of your Avid Elixir brakes. Look for markings on the caliper itself. Common models include:

• Avid Elixir R
• Avid Elixir CR
• Avid Elixir 5
• Avid Elixir 7
• Avid Elixir 9
• Avid Elixir CR Mag
• Avid Elixir XX
• Avid Elixir X0

For most of these, the standard SRAM/Avid replacement pads will be the correct fit. However, some very early or specific OEM (Original Equipment Manufacturer) versions might have had slightly different backing plates, though this is uncommon. Always refer to the product description of the replacement pads to ensure they explicitly state compatibility with your specific Elixir model.

Where to Buy Avid Elixir Brake Pads

You have several excellent options for purchasing replacement brake pads for your Avid Elixir brakes:

• SRAM Official Parts: Purchasing genuine SRAM/Avid branded pads guarantees compatibility and quality. These are readily available through authorised SRAM dealers and online retailers.
• Aftermarket Brands: Many reputable aftermarket manufacturers produce high-quality brake pads designed to be compatible with Avid Elixir calipers. Brands like Shimano (though less common for Avid, some universal pads might fit), Jagwire, Kool-Stop, and EBC are well-regarded. When choosing aftermarket, ensure they explicitly list compatibility with Avid Elixir brakes.

Replacing Your Avid Elixir Brake Pads: A Step-by-Step Overview

Replacing your brake pads is a relatively simple maintenance task that can be done at home with basic tools. Here’s a general guide:

1. Preparation: Gather your new pads, a suitable Allen key (often 5mm for the caliper bolts), a clean rag, and possibly some isopropyl alcohol for cleaning. Ensure your bike is stable, perhaps on a work stand or propped securely.
2. Remove the Wheel: If necessary, remove the wheel from the bike to gain better access to the caliper.
3. Locate the Caliper Bolts: Identify the two bolts that hold the brake caliper to the frame or fork.
4. Remove the Caliper: Carefully loosen and remove these two bolts. You don't necessarily need to disconnect the hydraulic hose, but be mindful of where the caliper is positioned. Gently pull the caliper away from the rotor.
5. Remove Old Pads: Once the caliper is free, you should see the brake pads held in place. They are often retained by a spring clip or a small retaining pin. Remove this retaining mechanism. The old pads should then slide out. You might need to gently pry them out with a flathead screwdriver if they are stuck.
6. Compress the Piston(s): Before inserting the new pads, you'll need to push the brake piston(s) back into the caliper body. This creates space for the thicker new pads. Use a clean, flat tool like a tyre lever or a dedicated pad spreader. Be careful not to damage the piston seals.
7. Install New Pads: Insert the new brake pads into the caliper, ensuring they are seated correctly and the retaining clip or pin is reinstalled.
8. Reinstall the Caliper: Position the caliper back over the rotor and reinsert and tighten the caliper mounting bolts. Ensure the caliper is centred over the rotor for optimal performance and to avoid rubbing.
9. Bed-In the Pads: This is a crucial step for achieving optimal braking performance. You'll need to perform a series of controlled stops. Find a safe, open area. Accelerate to a moderate speed (e.g., 10-15 mph) and brake firmly, but not to a complete stop. Repeat this process 10-20 times. This transfers a thin layer of pad material to the rotor, creating a more uniform and powerful contact surface.

Common Issues and Troubleshooting

Even with the correct pads, you might encounter some common braking issues:

• Squealing/Screeching: This can be caused by glazed pads, contaminated pads, or improperly bedded-in pads. Cleaning rotors and pads with isopropyl alcohol and re-bedding can often resolve this.
• Reduced Power: Ensure the pads are fully bedded-in, that there are no air bubbles in the hydraulic system, and that your rotors are clean and not excessively worn.
• Brake Rub: Check that the caliper is centred correctly over the rotor and that the rotor is true (not warped).

When to Replace Your Brake Pads

Regularly inspect your brake pads. Most Avid Elixir pads have a wear indicator groove. When this groove disappears or is very shallow, it's time for a replacement. Visually, if the friction material (the pad itself, not the backing plate) is less than 1mm thick, they should be replaced. Ignoring worn pads can lead to reduced braking performance, rotor damage, and potentially a complete brake failure.

Frequently Asked Questions (FAQs)

Q: Can I use Shimano brake pads in my Avid Elixir brakes?
While some aftermarket manufacturers produce "universal" pads, it's generally best to stick to pads specifically designed for Avid Elixir calipers. The shape and compound can differ, leading to poor performance or damage.

Q: How often should I replace my Avid Elixir brake pads?
This depends heavily on your riding style, terrain, and the type of pads used. In dry, dusty conditions, organic pads might last a few months, while metallic pads could last much longer. In wet, muddy conditions, expect them to wear out faster.

Q: What is "bedding in" and why is it important?
"Bedding in" is the process of transferring a thin, even layer of pad material onto the rotor surface to optimise braking performance. It ensures consistent power, better modulation, and reduces noise and glazing.

Q: My new pads are making a lot of noise, what should I do?
Ensure the pads are correctly bedded in. Sometimes, new metallic pads can be noisy until they wear in. Cleaning the rotor and pads with isopropyl alcohol and re-bedding can also help. Ensure the pads are installed with the correct spring clip.

Q: Do I need to replace my rotors when I replace my pads?
Not necessarily. Rotors should be replaced when they reach their minimum thickness (usually marked on the rotor) or if they are significantly warped or damaged. However, it's a good idea to clean your rotors thoroughly when changing pads.

Conclusion

Choosing the right brake pads for your Avid Elixir system is vital for safe and enjoyable cycling. By understanding the compatibility, different compound types, and the importance of proper installation and bedding-in, you can ensure your Avid Elixir brakes perform at their best. Whether you opt for genuine SRAM parts or a reputable aftermarket alternative, always prioritise quality and ensure the pads are listed as compatible with your specific Elixir model.
