Just replaced my rear tire and so was doing the usual obvious things whilst wheel was off (shaft lube, bearing check, pad check / caliper service etc) and got to wondering about the buttons that attach the disc to the carrier ... not so much for the back but am planning on checking the front brakes next.
This is something that I must confess to have not paid much attention to in the past ... I did some searching and came across some cautionary discussion of penetrating oil, appropriate lube (dry) and also docc's mention of using a mallet to ensure the buttons are free and the disc centred on the carrier in his checklist.
Just how much discernible play should there be in the buttons I wonder? In the case of the rear, I could not detect any. I would be more concerned about the front than the rear ... healthy front brakes are a good thing!
Thoughts /advice anyone?
