It turns out that riding the Bakfiets in all weathers as a family car/removal van/pickup truck/farm tractor, on and off-road in some very hilly places does make an occasional bit of maintenance necessary. Last week the brakes began to protest at my callous lack of attention to their needs by making a high-pitched squeal that caused dogs to howl, horses to bolt and cows to go off milking every time we tried to slow the bike down.
Not having any real experience with roller brakes I sent off an email to the nice people at Workcycles, who as usual responded extremely fast with the advice that the brakes need greasing now and again, preferably about every six months: the Bakfiets is nearly five years old so it was probably a good time to start, once I’d worked out how.
A quick search with the mighty Internet returned lots of advice, mostly with pictures of people dismantling entire hubs and rebuilding them, which was a bit beyond my capabilities, but the Shimano website helpfully showed an exploded diagram of the hub with two little holes which were apparently there for the purpose of adding the grease, but not just any grease, oh, no: this job called for the super-duper Shimano wonder goo which costs the same as molten gold but obviously absolutely essential as with a normal inferior grease the whole brake system would be destroyed. If I hadn’t managed this already.
I rode the Bakfiets over to my friendly bike shop for advice, and after the owners’ ears had finished bleeding from the noise he confirmed that grease was needed. I asked tentatively how much the whole operation would cost, given that the brakes were badly abused in the first place, possible removal and replacement of the hub, and the liquid gold that would be needed to avoid disaster.
He got out a syringe and squirted normal gearbox grease into the two holes. Sorted.
I showered his tips jar with gold, bought two brake levers for the Xtracycle (another story I’ll bore you with sometime) and cycled home. Not a squeak from the brakes.
