I have an Agattu B8 with hydraulic rim brakes. It's 5 years old; the brakes need bleeding once a year. Last year the big bike shop in town told me the brakes are obsolete and they can't service them any more. This year I took it to a small bike shop where they assured me they could do the job. They were optimistic. In the end, it took them 8 weeks and they told me they had to order a "hard-to-find" part to bleed the brakes. Have others had this problem? If so, does anyone have a solution? The big bike shop's solution was to buy a new bike.
