- Shimano brake mess up? is a 160mm rotor not just a 160mm rotor?
Hey guys, a little help if possible…
The GF has been complaining of loud, and under power brakes on her hardtail, she has old style deores on it, but new style deores on her FS, naturally, ive been ignoring her, and putting it down to the old style being less powerful.
I may have gotten things wrong with that though, as i have gotten round to investigating it, levers seem solid with a good bleed, calipers pretty central, not obvious warping of the disc, however….
The discs seem to be sitting in the caliper correctly, but they distinctly look like they are wearing too far into the disc, the pads seem to miss the outer edge, and wear the spider arms….
I have found a shimano compatibility chart p24 of which seems to suggest that the brakes, BR-M446 are not compatible with SM-RT64 rotors.
It also suggests that the calipers are not compatible with sintered pads
are 160mm rotors not just 160mm rotors…
I owe the GF an apology for ignoring her don’t I? can someone confirm my error?

that did occur to me, but the front isn’t using an adapter at all and is 160mm post mount and looks exactly the same…
we did change rotors (a little while ago) but was a straight swap for 160 to 160, and i dont think we did anything to the adaptor

The Deore calipers need a wide disc “track”, the discs you have look like SLX which have a narrow disc track:
I can’t remember which Shimano publication I got this from, but it shows what is avaliable.
(P.S. I have a brand new pair of the SM-RT61 metal-compatible deore discs if anyone is looking for some.)Posted 2 years ago
