I am enquiring about the drum brake, not the disc brake. Why I am asking this question because, in my location jawa service centre not doing a counter sale of parts and they informed me that if I want to do any work on my jawa bike, it has to be done in their service centre only and the cost is double or more than the normal rate. For replacing the back brake, they informed me the overall cost including labour will be Rs. 700. I found the back brake size of Jawa and bullet/classic 350 the same 153mm. So I need to know whether the brake shoe of bullet/classic 350 the same.
