Disk brakes might be useful
I went for a ride last Saturday -- it was neither long, nor fast, nor
scenic, a little trip to a neighboring town. On the way back it was about 25F (-4C), below freezing, but hardly frostbite weather. The sun was shining, the wind was blowing, the crows were singing merrily to keep the seagulls in their place. The streets were mostly clear, at least in the travel lanes, but were damp with melted brine. We haven't had much snow this year, and local governments are dealing as best they can with the dire prospect of a road salt budget surplus. The brine tends to get tracked into the mean right tire track, forming a dark stripe, which is where I rode a great deal of the time. To the right were piles of ice and snow, patches of crusty salt, dog**** popsicles and cigarette butts. To the left it was already a bit hard for drivers to pass. Two blocks from home, having not touched the brakes in quite a while, I meant to slow for a left turn, and applied the brakes. Just perceptible slowing obtained, even when squeezing hard. This was a little disappointing, not what most would expect from brakes at all. Unlike rain, the problem didn't go away as water was wiped from the rims -- it stayed crappy until I almost missed my turn in the neighbor's front yard. When I got home I looked at the rims. They were coated in white frosty stuff that looked a lot like snow, but stuck much more resolutely. Not normally much for washing bicycles, I spent a few minutes cleaning off the frost and salt. To be clear, the brakes are not modern equipment, but Weinmann Vainqueur centerpulls, albeit with Kool Stop cartridge pads. I do find them more than adequate ordinarily. If I ever buy a new bicycle, I believe I'll favor those fashionable disk brakes. -- |

Sometimes I had to let the pads gently rub on the rims well before an intersection to make sure there'd be some stopping power. Rim brakes are about as "modern" as those wood blocks against the wheels of a chuckwagon. Also, winter rides tend to eat rims. So do rain rides. Replacing a brake rotor takes five minutes (with coffee) and about $20-$25, changing out a rim is a different story. When I got home I looked at the rims.

Problems that cyclists have dealt with just fine for 100 years, but can suddenly be solved only with newly fashionable equipment! Yes, it's a good idea to occasionally test your brakes in bad conditions. It's not difficult. I've been doing that since the 1970s.

I ride all year round and I don't have problems with my rim brakes stopping any of my bicycles. That is even true for my ancient long out of production Shimano Adamas AX brakes and my Shimano Dura Ace AX brakes. Grant the Dura Ace AX bicycle is kept for nicer weather but I have got caught out in the rain with it and never had a problem. Not have i ever worn out a rim because of brake wear. I ride thousands of miles every year too. I just don't get how some people have such drastic problems with rims wearing out. Cheers |

Actually I've had exactly the same happen on rim brakes as described by the OP, but it is rare, you do need just the right combination of conditions. Freezing rain will do it as well :-( For me, Shimano mineral oil disc brakes have been maintenance free for years now. Was looking at the front disc over the weekend and it might be due for replacement after some 8,000 miles. Given it's a centerlock, that's going to be a 2 minute job! |

I have to "burp" mine about once a year or about every 2000mi but it's a mountain bike where I am in the brakes all the time. Mine use DOT-4 fluid so it's a bit of a messy job. Open reservoir, squeeze lever over and over again until no more bubbles show and the pressure point becomes hard, top off, close, wipe clean. That takes only a few minutes but DOT-4 can be nasty on clothes. So maybe my next set of brakes should be Shimano. ... Was looking at the front disc over the weekend and it might be due for replacement after some 8,000 miles. Given it's a centerlock, that's going to be a 2 minute job! With the six screws it's five minutes because there is usually a set of fresh ones with Loctite already applied.
