Overview
What makes the Shimano P03A-RF resin pad good for long descents?
The Shimano P03A-RF Disc Brake Pad and Spring is a finned resin pad built to keep braking quiet and fade-free on long, steep descents. The aluminum radiator fin pulls heat out of the pad and caliper, so power stays consistent when you are dragging the brakes through a sustained downhill. The third-generation resin compound delivers low noise and smooth modulation, giving you fine control over how hard you bite.
This is the narrow P-type pad shape for Shimano four-piston calipers, and it fits the XTR BR-M9220 and XT BR-M8220 brakes. It ships as one pair with the pad spring, ready to drop in. Best for the trail and enduro rider running current four-piston XTR or XT brakes who wants the heat management of finned pads with the quiet, controlled feel of resin.

Good questions
Get to know Shimano

There's more to Shimano than this one product. Our Shimano page has the full Shimano lineup we carry and more about the brand.
Visit the Shimano page →Which calipers does the P03A-RF fit?
It fits Shimano four-piston calipers BR-M9220 (XTR) and BR-M8220 (XT). It is the narrow P-type pad shape.
Why choose resin over metal pads?
Resin runs quieter and offers smoother modulation than metal, which is what most trail riders prefer. The finned design adds heat management so resin holds up on long descents.
What does the fin do?
The aluminum radiator fin draws heat away from the pad and caliper. That cooling keeps braking consistent and reduces fade on sustained downhills.
Does it come with the spring?
Yes. Each set is one pair of pads with the pad spring included, ready to install.
