Brake shoes

Though brakes can be good on dry days,

sludge accumulating on the brake shoes

on wet days makes them inefficient, or

even useless, causing the rider to be in

danger from faulty brakes. Also, if silt

particles accumulate with the sludge on

the brake shoes, the rim will blow. This

means that rims will often have to be

replaced and this incurs high costs to the

rider as well.

In order to avoid safety problems and

improve brake efficiency, we have had 

this idea: to install a blade similar to a

windshield wiper in front of the brake to

wipe away sludge and sewage before

they reach the brake, so that the brake 

may brake the bike cleanly.
