Problems with Shimano brake pads(8 posts)

Problems with Shimano brake padspeloton
Jul 28, 2001 7:03 PM
I have run Shimano brake pads for years with no problems. I recently put a set of Dura-ace brake pads on my Ultegra calipers, and haven't been impressed with the performace. The pads seem very soft, and pick debris up easily. I have actually picked pieces of metal out of the pads. The debris being picked up is harming my rims, and sounds horrible when it drags on the aluminum of the rim. The braking power also seems lower than what I have come to expect. I really don't have faith in these pads to haul me to a stop from speed. It's more like a subtle slowing of the bike, than real stopping power.

Does anyone know if Shimano produced a bad batch of pads recently, or is this some new 'improved material' now being used on the pads. I'm a little surprised, as I have not had problems in the past. I'm thinking of getting some Kool-stop pads or Ritcheys. Anyone have any preferences to non-Shimano brands?

I had the same problem with the Shimano M55/T brake pads.
I replaced them with Koolstop Salmon pads and these have
been great.
Possible Ceramic rim padsixiz

Shimano at one time was shipping their brakes with Ceramic rim compatible pads. You may have purchased aset for ceramic rims

To reduce the amount of aluminum or debris embedded into the pads
1. clean them after a wet ride
2. clean them monthly
3. toe the pads in the back a little to scrape some debris of the rim befroe engaging the pads.

Get Ultegra pads to me they are better but if you want to improve braking then you may need non D/A brakes

Thanks for the replies.

I am sure these aren't ceramic brake pads, I checked this before when I considered that I may had inadvertently installed ceramics on my brakes. I am very careful to keep my bike clean and well maintained. I Scotchbrite the rims and sand the pads once a week when I give the bike it's weekly tune. I try to do what is needed in between tune-ups too. That is the reason that I suspect that there is something wrong with this set of pads I recieved. I have never had these problems in the past though, which leaves me a little puzzled. I think I'm going to look for another set tonight. Thanks again.

I'm not sure what the difference is, but I noticed that Shimano has 2 DA brake pads listed - a standard, and a high performance. Maybe it was just a bad batch. Check with Shimano &/or wherever you purchased them, to see if there have been reports of similar incidences. Last resort, just change pads and see how they function.

I'm thinking also, perhaps a bad batch. I've have extremely good luck with Dura Ace brakes pads. I think my last Dura Ace were high performance, can't remember, but they were expensive. I originally picked up some Kool Stops, but they were for ceramic rims and I had to return them. I clean my rims a couple of times a week with full strength Simple Green and it removes all the rubber residue. I seem to recall when I bought my bike ('99) Dura Ace was having trouble with their brake pads, rubber was soft and wore quickly. Maybe you picked up some of the old ones....

They're supposed to be an all weather pad that works well when its wet. Maybe they work well when its wet, but I found them to work poorly when its dry (which is about 98% of my riding time). They made a scraping sound and didn't stop too well. I replaced them with the standard DA pads which I find are quite good. Try another set and make sure they don't say "high performance" on the package.

Do they even make Ultegra pads for 9-speed? I don't think so.
There was a recall....grzy mnky

I remember there being a recall and a buddy had similar problems until he swapped out his pads. Just put a new set on the wife's bike (similar vinatge w/Ultegra 9) and she noticed greatly improved braking performance this past weekend. Sounds like you got some bum pads.
