I assume we are talking about your 82? 450T if so, it is over due for brake rebuild kits if they still have the original stuff in there. You can make a nice bike out of that BTW, so don't fuck it up.
This is a 400, but probably worthwhile for you to read. https://www.caferacer.net/forum/proj...ly-driver.html
If you have images like this in your head, its probably best if you don't come out of the closet.
