Joined: 17 Sep 2011 Posts: 1 Bike: | I have recently tried to do a quick service and clean of my bike and would be very grateful for any advice on maintaining and cleaning disc brakes. Mine seem to be making a scraping noise and screech when I brake following removal of the rear wheel to fix a flat. Sorry if this is a blonde question , but any advice gratefully recieved! |

Also about maintaining them I get my bike annualy serviced by halfords :-) Storm Warner warner.storm@gmail.com |

Reassemble and make sure you change your disposable gloves if you use them before reassembly. As for Halfords I would not let my local one within 50 miles of my bike. I do most of the work myself or go to specialist shop for repairs which i dont feel able to do. |

Someone gave me this tip or it could have been the park tools Blue book I borrowed off a mate for about 6 months. Loosen the screws that hold the housing to the frame a little bit, so that there is a bit of play in them. Now apply the brakes and leave them on (i use a bungy cord). Now tighten the screws you loosened earlier - this should result in brake and pads being centered. If one pad is significantly more worn that the other replace it. Regarding cleaning i just pop the pads out and brush them off and brush inside the housing with a small brush. I usually do this dry i think it comes off easier dry. I just re-read your post. Also check that the wheel is returned with the same pressure on the screws and quick release as it was when it came off. this can result in the wheel being a bit off centre when it goes back on. Develop a routine in the number of turns of the screw when taking it off as when it goes back on. Good luck and keep those pedals turning. Buster |
