Hey, I’ve looked at some videos for cleaning/renewing the brake and the procedure is partly different. Unfortunately, people often don’t explain why they do something. My question now concerns the brake cylinder and the guide bolts. Should I clean the brake (it squeaks sometimes) also the guide bolts. Why not? With what should I lubricate the bolts? Brake anti-quiet paste from Liqui Moly I would have already there. In a video ha I have also seen that someone takes lithium grease but with 120° resistance it seems to me a little undersized. Should I lubricate the brake cylinder? If so, can I use the brake anti-quiet paste? Why not? Thank you for your help!
