I am not sure if this is the best place to post this.
I am desperately trying to find out what kind of brakes these (picture link attached) are and where and how i can get replacements. i know they say dia compe on them but thats about as much as i can read.
whenever i go to a shop, they hand me a pair of shimanos and tell me those will work. because i know this is not as simple of a problem, i ask them to put them on and when they try, it anything they try doesnt work. then im told a long story of how i need to get the bosses re-welded, etc etc.
I would like to know as much information as possible, specifically:
what kind of brakes are these (model, type)
where can i get replacements
what company makes replacements
if no replacements exist, where are my best and cheapest options
the bike i have was given to me. its a really old bianchi. i hope the pictures are sufficient. please let me know what you can.
