Shimano road bike disc brake pads are popular among cyclists, offering reliable stopping power and durability. However, there may be times when you need to find an alternative to Shimano brake pads, such as when they are unavailable or when you want to try a different pad type.
In this article, I’ll list the alternatives to the standard Shimano road bike disc brake pads.
Brake pad alternatives to L05A, L04C and L03A
All Shimano road disc brake calipers use the same brake pad shape. Hence, they are compatible with each other. The differences lie in the year of release, brake pad compound, back plate material, and cooling fins.
Most cyclists use the Shimano L05A, L04C, or L03A brake pads on their bikes today. Older models, such as K05S-RX, K04S-MX, and K03S-MX, are discontinued.

How to read Shimano brake pad model names
Shimano uses a system of letters and numbers to identify their brake pads, and understanding this naming system can help you choose the right pads for your bike.
Here’s a brief explanation of how to decipher Shimano brake pad model names:
The first letter in the model name signifies the material of the pad:
- L : Narrow Type L
- K : Narrow Type K
- G : Narrow Type G
- J : Narrow Type J
The second letter in the model name signifies the generation:
- 01 : First generation
- 02 : Second generation
- 03 : Third generation
- 04 : Fourth generation
- 05 : Fifth generation (current)
The third letter in the model name signifies the back plate material:
- A : Alloy
- S : Stainless steel
- Ti : Titanium
- C : Composite (alloy and stainless)
The fourth letter in the model name signifies the pad material:
- R : Resin
- M : Metal
The fifth letter in the model name signifies the presence of radiator fins.
- F : With fin
- X : Without fin
Note : L and K models are cross-compatible although they have different shape. The difference is all K brake pads have no fins.
For example, the L05A-RF which is the default brake pad for 12-speed Shimano groupsets, is a fifth-generation, resin brake pad with fins.
