Shimano brake pads vs. Koolstop(10 posts)

Shimano brake pads vs. KoolstopHeisssenberg

I have the Shimano R540 wheels and ultegra brakes. On the reviews of the wheels one person said to replace the Shimano "crap pads" and replace them with Koolstop. How seriously should I take that advice?
Worked great for meCory

Don't know about Ultegra pads, but I have low-line Shimano cantis (LX, I think--got 'em out of the parts bin and I can't remember) on my Atlantis. On that, Kool Stops are much better than the stock pads. They don't stop a lot shorter, that I can tell, but the feel is much better, more linear and easier to control. Well worth the money, IMO

I would recommend the Koolstop pads over the stock Shimano Ultegra pads. My Ultegra brake pads scour my Open Pro rims very badly. Its even worse when riding in the rain.

Changing to Koolstops solved this issue. Even tried Avid brake pads and they are much better.
Dura-Ace pads are garbage..Qubeley

I didn't have much trouble with Ultegra. After my ultegra has run out, I replaced them with Dura-Ace. First day of use, I heard grinding noise while breaking. It turned out that sand and little rocks get enbeded in the pad. I cleaned the pads, and it did not take long for the pads to pick up more little things to grind your rim. I ditched the pads after a week, left some scratch on my rim.
Switched to Koolstop, no more problem.

how seriously? up to you.

I've replaced 2year old Ultegra with salmon Koolstops and saw noticeable improvement in braking (esp in wet). Also Koolstops seemed to be less abrasive and easier on rims.
Toe in w/ Koolstop?pitt83

Based on the mantra of this board (Velocity Aerohead, Tacx cages, Vredenstein Fortezza and Koolstops) for required equipment, I've also switched. Only problem is: The toe in with the KS is way off compared with perfect toe in with Ultegra pads. I've adjusted the brakes outward, but there's too much clearance for my liking now. I want the pad 1-2mm max from the rim and I've only got that in the back where the pad tapers out. The front of the pad is a good 4mm away.

Should I bend the arm of the brakes to adjust for it or live with it? Did I mess up installing?

PS: MUCH less brake /rim grime with the salmons. Will get these in cantilever version for the CX bike soon.

KoolStop makes replacement brake pad holders that allow you to adjust toe without having to bend anything. I have one Ultegra and one DA brakeset and an assortment of KoolStop and Shimano brake pads and I can't say I've come across the same problem as you.

KS have the soft lip in the back of the pad /look at pic above/, it supposes to scrape water of the rim, is it what gets in a way?

No don't bend the arm, just file it off if you really need it. However, the "gimmicky" lip on KS will wear out pretty quick, you may just wait for a few hundred miles.
So, I'm not offpitt83

Looking at that pic, you see how the rear of the pad sticks out further. I'm just used to a flat contact of the entire pad all at once. I'll give it time. The lever travel is fine; I'm not in a death grip to get contact and stopping power. That's what really matters.

When I installed the pads, I realized that I either had to bend the brake arm or leave it alone. I chose option 2.

The KS really cut out that awful grime and work really well overall.

Thanks to everybody who replied. I'm going to my LBS and get some new pads for my new bike. ^_^ Kool Stop Salmons it is!
