SURFER Posted January 12, 2022 Posted January 12, 2022 I am currently using Shimano ultegra brake calipers with L03A resin pads on my roadbike. Need to replace the pads soon, but cannot find the resin L03A pads. Can find the metalic L04C pads. Have anybody used the L04C pads on their roadbike. I am just scared that it will be very noisy in normal conditions (dry).
SURFER Posted January 12, 2022 Author Posted January 12, 2022 I can also get resin Swisstop pads, I believ resin (not fin cooled). Disc 34 E
Eldron Posted January 12, 2022 Posted January 12, 2022 Resin is better for modulation and keeping noise low. Shorter life though. The combination of fine sand and wet destroys resin pads super quick (ask some Epic riders!). Metal is better for life but worse for modulation and makes a bit of noise (especially when wet). Check your rotors though - some are resin only (it is etched on the outside face of the rotor). Manufacturers are guilty of speccing cheaper rotors to save costs so check your rotors before adding metal pads.
SURFER Posted January 12, 2022 Author Posted January 12, 2022 Nothing on outside of rotor referring to resin only. Got Ultegra SM-RT800-S rotors Eldron 1
droo Posted January 12, 2022 Posted January 12, 2022 Another thing to know is that once you've used sintered pads on a rotor, you can't go back to resin. The sintered pad material that gets embedded in the rotor will trash a set of resin pads in record time. Trashy, stefmeister, Yyyy and 1 other 2 2

No threat of that in Denmark though - resin pads last about 20 minutes here.
SURFER Posted January 12, 2022 Author Posted January 12, 2022 Good to know. Will probably replace rotors after next set of pads

My other favourite "it's pretty obvious but nobody does it" is bedding in pads. A few minutes of bedding in when you change rotor or pad makes for a better overall braking experience.

A few minutes of bedding in when you change rotor or pad makes for a better overall braking experience. You mean it actually allows you to stop... If you understand how disc brake friction material transfer works it's a no brainer, but not many people are that interested in these things. Also it's the kind of thing that you don't know that you don't know, so you wouldn't even know to look for the information. Most people don't know because motor mechanics do it for you when they change pads, and a decent bike mechanic should too. Eldron 1
