I just pulled the rear wheel off my bike and as you know, you take the rear brake unit off the swingarm at the same time. Well once I had the unit off I had a quick inspection of the swingarm locator (on caliper)and it has worn where it locates on the swing arm.
About .125mm not all the way along but around 1/2 the way. Has anybody noticed this as well?
The rear wheel wasn't loose and the brake assembly was correctly located.

The "tongue and groove" does not need to be a tight fit. When the axle is tightened, the carrier will not move.

An 1/8 of a mm is only .005".

Scott F,
I realise the measurement(0.12mm)but I got carried away :).
The caliper must be moving even though the rear axle is done up tight!
I just needed to know if anyone else has noticed abnormal wear? next time you have the back wheel off check your tongue and groove to see if it's worn.
I do drag the back brake a little more than the average guy due to my days in road racing.
Thanx heaps

YZR426,

I had mine off yesterday and did not notice anything abnormal. It is common for a little bit of wear to occur there. Keep an eye on it to see if it continues to get worse.

I have had my swingarms polished, and the brake boss was noticeably worn down by the polishing. It had no adverse effect on brake performance.
