I found this thread useful to solve the
exact same issue.
Since I live on the top of a 1:7 1/2 mile long hill I use the brakes a lot so sooner or later I'll be needing to replace the whole (roller brake) unit. I had a look to see where I could buy one and this raised a few questions
1) a Dia Compe MLB-50 is available (from Japan - postage to UK doubles the cost
) but is that the correct unit for the E-Voyager Pro-Rider ?
2) does the replacement have to be Dia Compe or is there a generic alternative (e.g there are some "servo 90" units on
Ebay that look similar and are much cheaper) ?
