TrialZonn Posted July 18, 2009 Report Share Posted July 18, 2009 Hello to everyone.Yesterday, while I was bleeding my rear Magura brake, accidentaly some of the oil (magura royal blood) leaked from the lever to my front disk brake.One whole day has passed but my disk brake continues to slip and it makes a loud noise like the rear.I tried to clean it, especially the rotor and the pads but nothing worked.Any ideas?What can I do for it?Many thanks Quote Link to comment Share on other sites More sharing options...
DannyBazz (: Posted July 18, 2009 Report Share Posted July 18, 2009 the oil has contaminated the pads... and as far as I'm aware you can't clean pads so you will need new ones..as fir the rotor... I'm retty sure that giving it a good clean will sort it.. xx Quote Link to comment Share on other sites More sharing options...
Jack Morton Posted July 18, 2009 Report Share Posted July 18, 2009 When this happened to me i just burn't it of with a blowtorch. I've found it work's really well. Havn't had any problem's from this yet. Quote Link to comment Share on other sites More sharing options...
Prawny Baby Posted July 18, 2009 Report Share Posted July 18, 2009 the blow torch method can some times help a little, if it's a small amount of oil, but more often than not it doesn't work.the pad material is very porus, and any oil on the surface will quickly soak through the pad, leaving it totally useless.I'd take the rotor off, and give it a REALLY good clean with a strong detergent and lots of hot water, then buy yourself new pads.

Maladie Posted July 18, 2009 Report Share Posted July 18, 2009 As for the rotor mate, that can be cleaned easily.With the pads, being a dick I got WD40 all over mine before,I took my bike to a shop and what he did is basically rode the bike aroundfor a couple of minutes with the front brake litterally fully pulled in.Was the loudest few minutes of my life i swear But anyway, after he stopped he quickly got soem cold water and poured it all over the pads.Lots of steam started coming from the pads and basically that burnt all the WD40 off them.Works a treat now, even better than before Quote Link to comment Share on other sites More sharing options...
TrialZonn Posted July 18, 2009 Author Report Share Posted July 18, 2009 Thanks!I think I will try it and see! Quote Link to comment Share on other sites More sharing options...
TrialZonn Posted July 18, 2009 Author Report Share Posted July 18, 2009 (edited) I tried everything you told me, but unfortunately nothing worked...maybe the oil leaked on the pads was too much...So..I think I need new pads...Do you know if I can find pads for the Onza Dual-Pull mechanical disk brake?(It is the one attached to the newer models).(I made a topic at the wanted section too but until now no replies)And if I can't...for how much can I buy a second-hand Avid BB7?I have heard that it's a good brake if compared with the right lever.Many thanks Edited July 18, 2009 by TrialZonn Quote Link to comment Share on other sites More sharing options...
LukasMcNeal Posted July 19, 2009 Report Share Posted July 19, 2009 I think there is some muc off disk de contaminant spray you can get, but I'm not sure if it does pads. Quote Link to comment Share on other sites More sharing options...
t33zr Posted July 19, 2009 Report Share Posted July 19, 2009 Do this several times to the pad does not make anymore smoke. Then its good as new.Be carefull, because this smells like shit in ur kitchenalso u can do this with the disc also. then its all good as new.

Tomm Posted July 19, 2009 Report Share Posted July 19, 2009 What Teezr said ^^Do that for the pads, but I wouldn't stick the rotors on the cooker - just use (very) soapy water - preferably with some kind of industrial-strength degreaser. If not, fairly liquid is actually pretty good. And then rinse with clean water very thoroughly. Quote Link to comment Share on other sites More sharing options...

Robin M S/c Posted July 19, 2009 Report Share Posted July 19, 2009 the best thing to do is to find a long steep hill and go down it with the brake on to get it really hot.Then put water on it so it steams all the oil off.Keep repeating until sorted.This is how all the motorbike trials guys and galls sort it.

TrialZonn Posted July 19, 2009 Author Report Share Posted July 19, 2009 I put my pads on the oven and waited until smoke comes off them and then repeated and repeated again...Also cleaned the rotor with degreaser and soapy water.When I fully biult the brake up and had a ride on the bike, I noticed that the loud noise stopped (I think this is good) but it seems that I have not the braking power that I had before this ''accident''.The brake feels a little spongy and it will not stop me if I go gapping to front...However it helped a little.Now it may be just that I haven't setup the brake correctly or so...I noticed that one of the two pads is worn in an angle.(but I had much more power with the worn pad before so it's not this that causes the brake to continue slipping...)

psycholist Posted July 20, 2009 Report Share Posted July 20, 2009 If the noise is gone then the contamination is probably gone too. Now you'll need to break the disk in again - get it hot and spray water on it. For even quicker improvement use muddy water... Quote Link to comment Share on other sites More sharing options...
