ashleys sugden Posted February 3, 2013 Report Share Posted February 3, 2013 Hi yesterday i was out riding, i was pretty determined to get this line done, which is like a double step rock and then a big ish pedal up after.. i was trying it for about an hour and i crashed, i ripped the front brake hose off with my leg somehow. i took the wheel out so the oil didnt go on my disc whilst waiting for my dad to pick me up. when i got home i washed the disc with hot water and the pads.. new hose and re bled and the brake works well, it just doesn't hold at all.. anybody have any solutions to getting it top notch again? ive never had any problems with hydro disc brakes before.. the brake is an echo standard front brake with magura disc and hope mono pro pads. thanks Quote Link to comment Share on other sites More sharing options...
Danny00135 Posted February 3, 2013 Report Share Posted February 3, 2013 I'd assume it's just a bedding problem :/ How long have you ridden it after cleaning? did you come straight to trials forum before riding it for a while? Quote Link to comment Share on other sites More sharing options...
trials hoe Posted February 3, 2013 Report Share Posted February 3, 2013 did you try soapy water? oil can be a bitch to remove you only need the tiniest bit on the disc/pads and it has drastic consequences, if you only used water and wiped it you just end up smearing it around.

Skoze Posted February 3, 2013 Report Share Posted February 3, 2013 (edited) Yeah it's probably contaminated, doesn't take much to do it. You can clean it all with meths, burn the oil off or just replace the lot which is generally the better shout even if it isn't too cheap.

FamilyBiker Posted February 3, 2013 Report Share Posted February 3, 2013 (edited) put the pads on a sandpaper on a glass surface or similar and sand the surface down a tiny bit. you need to bed them in after that but it works though if not,what skoze said Edited February 3, 2013 by FamilyBiker Quote Link to comment Share on other sites More sharing options...
ashleys sugden Posted February 3, 2013 Author Report Share Posted February 3, 2013 i rode it for an hour after hoping it would get better but it didnt, so i washed it all with hot soapy water, had the wheel off and the pads.. its gone better, but its still not how i like it, i will try the sand paper, thanks everyone Quote Link to comment Share on other sites More sharing options...
Duncy H Posted February 3, 2013 Report Share Posted February 3, 2013 You could also try putting the pads in a pan of boiling water for a bit. It can help draw the oil out. Quote Link to comment Share on other sites More sharing options...

isitafox Posted February 3, 2013 Report Share Posted February 3, 2013 I'd go with Skoze, new pads and disc to be sure. Quote Link to comment Share on other sites More sharing options...
ashleys sugden Posted February 3, 2013 Author Report Share Posted February 3, 2013 the pads aint even a month old yet so i dont see the point, i dont have a lot of money to spend on it. i have a few other discs though. Quote Link to comment Share on other sites More sharing options...
Skoze Posted February 3, 2013 Report Share Posted February 3, 2013 Cool, well clean the rotor with meths and leave it to dry naturally, then sand the pads down. Should be alright! 1 Quote Link to comment Share on other sites More sharing options...

customrider-Rhys Posted February 3, 2013 Report Share Posted February 3, 2013 find a good hill and be it in again? is it true that its best to use muddy water as it works as a grinding paste? if so try that Quote Link to comment Share on other sites More sharing options...
the mysterious leemur Posted February 3, 2013 Report Share Posted February 3, 2013 find a good hill and be it in again? is it true that its best to use muddy water as it works as a grinding paste? if so try that That only really works right after it happens , done it a couple times on my dh bike doesn't work amazingly but it'll get you home. Best in my experience , boil them then set fire to the pads and then a tiny bit of sanding. For rotor , give it a good sanding or bathe it in meths. The brake will work again but not as good as before maybe 75-85% of the previous performance. Best solution would be new rotor/pads. Quote Link to comment Share on other sites More sharing options...

Robin M S/c Posted February 3, 2013 Report Share Posted February 3, 2013 Ride down a steep hill with the brake on to get it really hot and then pour water on the disc and pads which should steam off all the contamination. Quote Link to comment Share on other sites More sharing options...
williams Posted February 3, 2013 Report Share Posted February 3, 2013 Wash your rotor in the dishwasher, and bake the pads of in the oven and then set them to fire, and then sand them The rotor will need to be bedded in like when it was new, going to take a while, like one ride. This would be my best bet, good luck! Quote Link to comment Share on other sites More sharing options...
isitafox Posted February 3, 2013 Report Share Posted February 3, 2013 At precisely midnight when the moon is full you must sacrifice a young virgin atop the tallest mountain in the High Peak summoning the dragon Hilgoroth. You must then mix a potion of frogs liver, the blood of a loved one and the dew from the first frost of winter, rub it onto the disc and pads and let the dragon cleanse the potion with his fiery breathe. This magic can only be performed once though after which a new disc and pads is the only solution. 9 Quote Link to comment Share on other sites More sharing options...
dave33 Posted February 3, 2013 Report Share Posted February 3, 2013 White spirits Don't use that it's oil based Mentholated spirits is what you need to clean the rotor, but your pads are contaminated with oil. You need new ones Quote Link to comment Share on other sites More sharing options...
dezmtber Posted February 3, 2013 Report Share Posted February 3, 2013 Do the sandpaper thingy. But before you put the pads back in. Leave them on the side for an hour say. If when you come back to check them the dusty surface has spots of damp on them the pads are contaminated with lots of oil. And you can only fix this with new pads and a really good clean on your rotor, no need to replace the rotor. If your pads are ok then just rebedding in 1 Quote Link to comment Share on other sites More sharing options...
Rockman Posted February 3, 2013 Report Share Posted February 3, 2013 Just buy new pads, It's pretty much impossible to un-contaminate pads, use a really good degreaser and soak the rotor, then clean it a few times. Quote Link to comment Share on other sites More sharing options...
SamKidney Posted February 4, 2013 Report Share Posted February 4, 2013 When my bro's front brake hose split at the calliper it sent oil everywhere. I stuck the disc in the dishwasher, and cooked the pads off at 150* in the oven for 10mins. Ran a file over the pads after they had cooled, used some fine grade sand paper on the disc, and set it all back up. Lethal brake, and still is. 1 Quote Link to comment Share on other sites More sharing options...

You can put them in the oven to evaporate the oil that's been soaked up but they are never as good as new pads that's some thing I have done in the past works ok Quote Link to comment Share on other sites More sharing options...
bing Posted February 4, 2013 Report Share Posted February 4, 2013 Clarkes hope mono trial/echo tr disk brake pads are 4 quid off chain reaction. stop being tight and just order some. you shouldn't need a new rotor if you clean it properly Quote Link to comment Share on other sites More sharing options...
