downhill_rob2@hotmail.com Posted October 15, 2005 Report Share Posted October 15, 2005 Hi people, got on my bike this morning, and started to ride and went staright over the bars, i then looked at my front brake and found out the front disk rotor is bent, but i dont know how its happened! I havnt landed/hit it on anything. Anyways, iv tryed bending it back, but it just wont, so i think im gonna go buy a new one, i just dont know what size it is. Could anyone help on the magura louise disk sizes please? Its the older style brake with the lumo yellow lever. Smallest size i think....

Backgren Posted October 16, 2005 Report Share Posted October 16, 2005 try to bend it back again, since buying a new one is very expensive... I've bend mine back a few times, im sure you'll get it straight enough. Quote Link to comment Share on other sites More sharing options...

Yeah, iv just bent it back enough to ride, but for some reason, my front brake has went shit and isnt as powerful as normal :turned: P.S going riding with jordy next weekend (Y) Quote Link to comment Share on other sites More sharing options...
Tomm Posted October 16, 2005 Report Share Posted October 16, 2005 Did you bend it back with your hands? You probably got greasy fingers all over it if you did... Get the adjustable spanner out and you'll be able to straighten it in no time. Quote Link to comment Share on other sites More sharing options...
CurtisRider Posted October 16, 2005 Report Share Posted October 16, 2005 just make sure the adjustable isnt oily :turned: Quote Link to comment Share on other sites More sharing options...

shovel Posted October 17, 2005 Report Share Posted October 17, 2005 yeah straightening it out would be alot cheaper than ordering a new one, although if it is really bent straightening will weaken it just remember to give the disc a good clean when you finished with it, whilst the wheels out you could always give the pads a quick clean with some sandpaper just incase they got greasy before Quote Link to comment Share on other sites More sharing options...
downhill_rob2@hotmail.com Posted October 17, 2005 Author Report Share Posted October 17, 2005 just went out on it for like 5 mins before school, it seams ok at the min, gonna straighten it out a little bit more tonight though. :turned: Quote Link to comment Share on other sites More sharing options...
Urpedigreechumdog Posted October 17, 2005 Report Share Posted October 17, 2005 Put the rotor between 2 flat, hard pieces of wood and hit them with a hammer. Quote Link to comment Share on other sites More sharing options...

Say, the rotor is bent 1cm to the right, to band it back to the middle, you will have to bend it back around 1cm to the left, enough for it to bend back into shape.
