yamahaty250xox Posted November 17, 2008 Report Share Posted November 17, 2008 1. remove brake pads, and coat the rear of them with copper grease. 2. run around a flat feild with the brakes fuly on until they are extreemly hot, then drench with water. hope this helps max Quote Link to comment Share on other sites More sharing options...

coxy Posted November 17, 2008 Report Share Posted November 17, 2008 whatever you do do not put wd40 on ur pads it stops the brakes from working!! as yamahaty said just take them off and copper grease the backs and then get the brakes red hot and then drench them in cold water, do this a couple of times and it should sort it.

frontroomautos Posted November 18, 2008 Report Share Posted November 18, 2008 wd40 all over Don't be silly! Do not get WD40 anywhere near your discs or pads. You will ruin your pads and won't be able to stop. Quote Link to comment Share on other sites More sharing options...
marky boy Posted November 18, 2008 Report Share Posted November 18, 2008 Notice the rolling eyes?? Well that was to show that i was been sarcastic and was trying to inject a wee smile . One of the lads that we ride with complained of a squealing brake and so his mate (at the start of the east yorks 2day too!!) poured engine oil all over his front disc & caliper (as a prank obviously), he didnt have a front brake for the trial, but it never squeaked all day !!!!!!!!!!!!

ham2 Posted November 18, 2008 Report Share Posted November 18, 2008 You may already have wd40/oil/grease tainted pads hence the squeal. I'm not a fan of the copper-slip method it can migrate when you go through a stream or wash your bike. If you don't want to buy brand-new pads:- Try removing the pads, put them flat on the deck,on a brick etc. -lining side up.- Then heat them up with a small gas torch (usual precautions mind) just enough to get the contaminants to bubble up and out. Lightly wire brush 'em to get that oxide off. Assemble the brakes and do the drag and quench method as previously described . Geordie tip,if you don't have any water handy,just pee on that hot disc (it's slightly acidic so it cuts through the grease)just don't let the neighbours see you doing it.
