Brake inspection.

These Shimano L04C Metal Disc Brake Pads are direct replacements for those found in Shimano's BR-RS805 and BR-RS505 road disc brakes. The metal compound provides better stopping power in all-conditions but is less quiet than the L02A resin compound model. Integrated cooling fins help shed heat to reduce brake fade under heavy or prolonged braking.

Sold as a set for one brake. Buy two sets to complete both front and rear brakes.

They provide stops, but also squawks.

Very loud when wet. Also a fair amount of noise when dry. I'll try the resin version next time.

Love these pads since I cook right through the resin ones. Well priced and last 3 time longer for me...

Great pads, only have noise when clamping down on wet rotors at slow speeds

On my second pair of these pads and don't really have any complaints. One issue I did have was when the shop replaced my front RT-99 rotor with the cheaper RT-81 rotor. This resulted in a ton of noise and squeaks when braking. Switched back to RT-99 rotor and problems went away.

Solid brake pads, but heat up relatively quickly and get squeaky.

These are great brake pads but I feel that after moderate use they get squeaky from heat. I would still buy again but squeaky brake pads are annoying.

Much prefer these to resin

After getting 1,000 miles on the resin pads that came with my Ultegra calipers, I decided to try the metal pads. After my first ride, I knew I'd never go back to resin pads again. I spent a lot of time to make sure they were installed correctly and centered. I have zero issues with noise and feel that my stopping power is phenomenal. I mostly ride in dry, high altitude conditions and have not tried them in the rain yet, but I'm very pleased with these pads and hope they last longer than my set of resin ones.

Got these along with new rotors for my rainwinter bike.

Yes they'll stop your bike well, but they squeal so loud, they can be heard for miles. Stick with the resin.
