Borat Posted January 2, 2010 Report Share Posted January 2, 2010 (edited) Easy Guys, I have getting pissed off with my 06 mono mini! I bought it off of Ashley Wood about a week and have bled it and everything. The inside of the caliper is clean (no dot4 laying around). But when I have decontaminated it, it's fine. But every morning I go to my garage to get the bike out, the brake is wank (feels contaminated) It squeeks and is terrible (slips etc). Nothing in my garage is falling onto the caliper/rotor in my garage. But I would really like to know your thoughts, but I have one sneaking suspision. The cap on the lever was fecked, it had a part of the seal bit out of it. I will get pics later (as it's to hard to explain). So I have got a mint cap thing off of simpsonigga. But I have the feeling I need a new diaphram? Any help appreciated. EDIT: It is quite damp in my garage!!!

Danny Posted January 2, 2010 Report Share Posted January 2, 2010 Are you bleeding it properly and rolling the diaphragm on properly? There's a video guide on the hope website. Quote Link to comment Share on other sites More sharing options...
Borat Posted January 2, 2010 Author Report Share Posted January 2, 2010 Yeah, I'm bleeding it fine. The actual problem I have is the fact it is totally gash in the mornings when I get it out of the garage? hmmmm Quote Link to comment Share on other sites More sharing options...
Sam F Posted January 2, 2010 Report Share Posted January 2, 2010 cold weather? i'm sure of it, does exact same on my mtb, squeeks, generally shit and yeah.. they was fine in the summer so.. Quote Link to comment Share on other sites More sharing options...
Matt Burrows Posted January 2, 2010 Report Share Posted January 2, 2010 Yeah the cold weather can effect things. It could be that your pads/rotor are slightly contaminated or not quite bed in properly, so they don't work very well until warm. Quote Link to comment Share on other sites More sharing options...
Borat Posted January 2, 2010 Author Report Share Posted January 2, 2010 Ahh, I see what you mean. But surley it wouldn't have much of an effect. Should it? Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 2, 2010 Report Share Posted January 2, 2010 If it's squeaky/juddery, it's your pads/rotor that's the issue generally. Just rinse it with a lot of clean water, and scrub the brake. Give it a wipe down and repeat until the rotor appears to be clean and the brake isn't squealing. Could be worse in the morning if the rotor's a bit damp 'cos it's dewy? Quote Link to comment Share on other sites More sharing options...

Ahh, thanks Mark will try that (cleaning it througherly) Would it be an idea to put a cloth of something over the rotor at night? Quote Link to comment Share on other sites More sharing options...
Rob Brodie Posted January 2, 2010 Report Share Posted January 2, 2010 jack. there must be some air in there. mines exactly the same. i had a leak and because hope are so f**king wank they didnt rebleed it when i sent it back. so now when its cold the air in the brake falls (because cold air falls) and its not untill it warms up that it rises. the squeaking is where its not kinda hitting the rotor right (thats what i think anyway) Quote Link to comment Share on other sites More sharing options...
Mark W Posted January 2, 2010 Report Share Posted January 2, 2010 Air in oil should pretty much always rise no matter what the temperature is... Quote Link to comment Share on other sites More sharing options...
Rob Brodie Posted January 2, 2010 Report Share Posted January 2, 2010 Air in oil should pretty much always rise no matter what the temperature is... im not going to say your wrong because i know your probs not but i definately think that's the case in my brake.

Mark W Posted January 2, 2010 Report Share Posted January 2, 2010 Preeeetty damn sure, same as how air gets trapped in high points on Magura hosing, the lever and in the cross over 'n' stuff. Quote Link to comment Share on other sites More sharing options...
DannyBazz (: Posted January 2, 2010 Report Share Posted January 2, 2010 Hmmm. Its weird, I'm getting this problem on my front disc... Even though its cable. After a while riding though, it generally heats up and gets better.... I think its something to do with the damp weather, maybe water soaks into the pads and freezes or something, then when the pads heat up the ice melts? I'm not too sure, but after a while riding it seems to regain power and hold Quote Link to comment Share on other sites More sharing options...
Sam Oliver Posted January 2, 2010 Report Share Posted January 2, 2010 Most deffo the cold damp thing, My brakes are loads better in the warm weather, I have been keeping my bike tucked up in the warm recently Sam. Quote Link to comment Share on other sites More sharing options...

Probably the same with your rotors if they get cold overnight, but once they've been used a bit they'll dry up and heat up. Quote Link to comment Share on other sites More sharing options...

Simpson Posted January 2, 2010 Report Share Posted January 2, 2010 Could be worse in the morning if the rotor's a bit damp 'cos it's dewy? Everyone always thinks that in LDN brakes react diferently to other places because its so dirty and close air? Urban myth? I'll let you judge!
