Squeal like a brake pad – redux

Kool Stop pads on the Open Pro rim, above, and Mavic MA2 rim below.


Back in 2009 I complained about squeaky Kool Stop brake pads. Fast forward ten years and I’m back to using the Continental style pads (still being sold), but no more squeal.

Jobst Brandt was a huge fan of Kool Stop pads. At one point back in the 80s I think every rider in his cadre switched to Kool Stop.

My guess is that the newer Mavic Open Pro rims I’m riding are less prone to grunge buildup compared to the Mavic MA2. I have photographic evidence. I could get the Kool Stop pads to stop squealing if I ran them through wet sand and applied the brakes, but the fix didn’t last.

The Shimano Ultegra brake pads I replaced had lost braking power. I noticed it on steep descents and even not-so-steep inclines.

Worn Shimano pad removed from its casing. Easy to remove them once you back out the screw with a 2 mm Allen key.


I think it’s mostly due to age. They were nine years old and had many miles. Rubber hardens with age and I think that contributed to the reduced braking power.

These Continental pads are old. They’ve been sitting in the garage for 15 years, but they work well. These pads last forever. They might just outlive me.

I don’t have any objections to Shimano’s pads. I wanted to use what was on hand and save a buck.

The Kool Stop pads I’m using have some cons. They’re ugly for one. They require a 10 mm wrench. I prefer an Allen key.

While my braking power is much better now, I should be using disc brakes for even better braking.

I’ve always preferred the simpler caliper brake, but nowadays my aging hands need all the help they can get.

    I love how well the Continentals work, but don’t dig the 10mm nut either. Have you considered Kool Stop “Dura” pads for your Ultegra holders? Pretty sure those would fit.
