Never thought I'd have to ask for help but I have drawn a total blank in my search for some plastic parts which are components of this Shimano design.
Overall the design seems sound, & whilst not as readily adjusted as more modern sets, the brakes have all the required stopping power.
For some unknown reason Shimano seems to have incorporated plastic shrouds which cover the 3 turn coil return springs, & as you might guess the plastic just fractures & fails.
My wifes bike has not really seen much work, & is stored out of sunlight, but these suckers just fail anyway!
At first I though these shrouds were merely dust covers but that's not the case as one in each pair carries an adjusting limit screw - creating some more stress in this thin walled component.
Can anyone suggest how I might obtain replacements. LBS - no stock of these bits, "cantilevers are pretty old now".
Thanks,
Peter O
