Stop Buying the Wrong Brake Pads! 3-Step Guide to Choose the Right Mountain Bike Brake Pads

Have you ever ordered new brake pads, only to realize they don’t fit your bike? You’re not alone. One of the most common issues mountain bikers face is buying the wrong model of brake pads—either they won’t fit the caliper, or they don’t perform as expected.

In this article, the Top Brake team walks you through a 3-step system to avoid model mismatch and ensure your pads are the perfect fit—so you can ride with confidence and zero regrets.

3-step system:
Identify brand → Verify model → Match shape

Step 1: Identify Your Brake Caliper Brand

Brake pads are not universal. Each brake caliper brand has its own shape and size requirements.

Common brands include Shimano, SRAM, Magura, Hope, Hayes, Formula, Tektro, and TRP.

Tip: Look directly at your brake caliper for a logo or brand engraving—this is your first clue. (Check Compatibility by Brand)

Step 2: Locate the Model Number on Your Caliper

Once you’ve identified the brand, check the caliper for the exact model—this might be something like:

• Shimano M6100, M7100, M8120
• SRAM G2, Code R, Level T, DB8 
• Magura MT5, MT7, MT8

The shape and size of your brake pads depend on this model number. Pads that look similar may still differ in fit, thickness, or pin position. Snap a photo of your caliper and model number for easy comparison!

Step 3: Match the Pad Shape and Size Before You Buy

Once you know your caliper’s brand and model, it’s time to double-check the pad’s shape and size.

Here’s how to do it:

• Visually compare your old pad with the product image on our website
• Measure the length and width of your used pad
• Make sure the outline, mounting holes, and general form match the website’s images

Note: It is normal to experience minor measurement differences, usually less than 1mm, due to wear or manufacturing tolerances. These small deviations are acceptable, as long as the shape and mounting points align correctly, the pad will fit and function properly.

Pro Tip: Matching just by memory or a similar look is risky. Take your old pad, measure it, and compare it directly to our photos for peace of mind.

Mistakes to Avoid When Choosing Mountain Bike Brake Pads

• “They look about the same, they should fit.”
• “It worked on my friend’s bike, so it should work on mine too.”
• “Shimano pads should all be interchangeable.”

These assumptions couldn’t be more wrong. Brake pad compatibility depends on factors like caliper design and manufacturing year, even within the same brand. Always double-check before making a purchase.

Once you’ve chosen the perfect model and shape, it’s important to understand the various materials used in brake pads and how heat management and brake fade can affect their performance.
