While my Indian Bullet 500 was having some jobs done recently, I asked the mechanic to open the brakes up and do a general check.
I provided the correct brake shoes... might as well replace while it's all apart.
The rear brake turned out brilliant. The front, however, no matter how much he adjusted it... beyond awful. Pulling the lever right back to the bars and the shoes barely touched the drum.
Was the drum badly worn? Well, it hadn't been with the old shoes one day before.
He eventually tried the old shoes and all was well.
We then tried an old shoe and a new shoe together on a flat surface, like two hump-back bridges. The old one was a hair's breadth smaller.
I then suggested putting them on the backplate and measuring: The new pair now about ¼" less across than the old ones.
He cleaned the old ones up, re-fitted them, and... perfect (or, anyway, as near as you can get to perfect on these Bullets.)
Check any new, perfect, lovely parts... of any sort... against the originals.
And I'll not be doing it just with brakes. LESSON FOR ME!
