keep mud off your bicycle's brake shoes
  [vote for,

Town cyclists stop reading now.

When cycling through thick wet mud, I find that unless I'm going particularly fast (bound to end up horizontal) I collect a fair amount of it on the wheels, which then collects at the next nearest obstruction, my brake shoes. When I then apply the brakes, they're next to useless with all that crap lubricating the wheel rim.

So I need a little pair of mudguards right in front of the brake shoes, rather like a snowplough (US: snowplow) so that the rapidly collecting mud can instead spray off to the sides in an eyecatching whizzy fashion. Pedestrians in the country watch out. Your clean trousers are safe no longer!

       one alternative is disc-brakes because they are very powerfull and also only affected by mud deeper than 12 inches   

       but i would also like to note that mud is worse when combined with dry leaves which forms a concrete-like substance encasing the top of your forks and your brakes and preventing movement (this happened so badly to my friend that we had to disconnect his brakes and spend 10 minutes digging at it with a stick)

       Peter, few 'adult' bikes come with them...kids' bikes usually do. Never understood why, except possibly that for racing bikes, they're extra weight that isn't wanted, and other types of bikes copied the style.   

       The mudguards <as the original idea> would have to actually be touching the wheel to scrape the mud off, and would cause drag. If they didn't, there'd still be a layer of mud and it'd mung the brakes anyway...I once saw a band-brake, a kevlar rope that squeezed a metal rim <kind of like a second tire mount next to the one the tire was on> when applied. They said it worked in water with no trouble.

       To prevent drag, instead of contact mudguards, you could spray a stream of some non-lubricating cleaning fluid on the rim at a spot before the brake.   

       And I'm Californian and I've never spelled snowplough with "ow".   

       (of course, being from Southern California, how often do I even spell snowplough, really?)

       Do you think it would work if instead of the mudguards being in contact with the wheel, the closest part of them was a brush? Peter, normal wheel mudguards don't seem to be standard over here either. But the stripe of mud up my back is the least of my worries. Last time I went cycling I came off three times into stinging nettles, once into a canal (fully in, head to toe soaked), and once on a main road in the city. All in the space of one afternoon. It was great fun!
(gt, the snowplow reference is probably because I was taught to read when very very young in Toronto, as I think I've said elsewhere on the site!)

       Never teach a young Torontulan to read?

       Mud! Thick red clay mud packing up between the brake pads and the rim until the latter no longer turns. Maybe very stiff-bristled brushes would scrape the mud with minimal drag, or perhaps--as lewisgirl suggests--plough-shaped tough plastic squeegee gadgets would be better. They might be mounted on pivots--maybe extenstions of the brake braze-ons--so that a rider can squeeze a lever and scrape the wheels for a while and then release them.   

       For Peter: stinging nettles, family Urticaceae: our western USA species is Urtica lyalli, Bane of Barelegged Fishermen, and grows chest-high on marshy streambanks under trees. The stinging is mildly painful but transient. Poison ivy and poison oak, family Anacardiaceae, contain irritant oils to which sensitivity in humans varies widely. Weeping blisters can last for a week or more in susceptible individuals.

       well, my friend did suggest that I might deserve a green beret for my efforts that afternoon. Out of "blood, sweat and tears" I am happy to say the only thing I didn't do was cry. Mephista, I am nowhere near competent enough to ride downhill - that is a recipe for disaster. Anyway, there aren't many big hills around Birmingham. I'm happy with canals - flat, usually with a reasonable path,and the added frisson of excitement caused by proximity to water (lewisgirl is a Pisces). Thanks for the botany lesson, Dog Ed, I'll remember that. My problem is that as well as getting the slight red blotchy rash one associates with nettles, I also seem to feel the tingling all over my skin. I suspect I may be a little bit extra allergic to it. Meph, you really are underestimating my novice status on a bike. I think I would probably be safer on your suggested tightrope than I would on a 'less is more' bike going downhill. However, if I do it, I'll make sure I put the pictures (and the subsequent x-rays) on the net for you all to see!

       Mud bikes are quite different to the California inspired MTB. Ideally they have one gear (often a fixed gear so there is no frewheel action), disk brakes, mud tyres with a profile that sheds mud and some form of mudguard mounted high up off the tyre. Problem solved.

       baked - i just got some new pads with a little wedge on the leading edge to clear mud and water off the rim when theyre pulled
chud, Jul 05 2002

       I just had this great idea, and here it is, 17 years old. I think the wedge is better than the squeegee or razor blade (my 2 ideas). They would deploy with the brake in advance of the pad to improve pad grip.

       Now, if only there were a system for clearing bits of cyclist out of the brakes of 4x4's ...
