Hope sucking

[Ross W.]

okay so I got a Hope mono trial for the front a bit ago, had it for a month, its been broken in. SO, it was working great for a while, then I go and ride while it was snowing out, brake got wet, made a lot of noise, so what? Well now it sucks ass, no grab. I thought the whole point of a disc was that water didn't affect it. I cleaned the pads with a clean rag, nothing more though. Any suggestions?

The rotor is slightly bent but I don't think that should make a difference, it was working fine until my wet/snow ride. Anyone else have this problem?

It shouldn't have an adverse effect with just water on your rotor/pads. However, if there was some gunky oil residue on the road or it got contaminated in some other way, you may get some bad results.

You can get brake cleaner at an auto parts store (there may be some cheap-o version that is worth trying). You can also go through the break-in cycle again and wear the pads and rotor to mate better with each other once again. If it comes down to it, use the cleaner on the rotor and get new pads if all else fails. The cleaner should help if they are gunked up, though.

i don't know if this helps you but don't store your hope equiped bike upsidedown, my brake turned to shit everytime I left my bike upsidedown.

[bushlawyer]

leave the bike in a hot car also seems to mess things up.
tho i live in australia and sounds like its pretty cold your way....

[Ross W.]

well, I don't store my bike upside down, and it definitely isn't hot here, so I guess maybe something got on the rotors. Seems like that would wear off though, and the brake still sucks after more than a week of riding.

Any other thoughts?

I would say that the rotors and/or pads were contaminated by something that was mixed in the water. First you can try cleaning the rotor with white lightning disk brake cleaner, or rubbing alcohol if that is all you have available. Then, if that doesn't work, change to new pads and clean the rotor again. That should solve your problems. :-)

its a hope, just looking at the pads makes them crap their pants!!

my mono trials was crap, would contaminate from anything and was shit in the wet.

PS, dont use disk brake cleaner made for cars, they leave a slight oily layer.....to stop cars disks rusting I think.

[djsmallfry]

yeah it was prolly road gunk... maybe salt... if they are metalic pads you can heat them up in an oven along with the rotor this will burn any gunk off (if they arnt full metalic dont do it!)

better idea tho:

white lightning "clean streak" is good for cleaning discs. and rotors.. it's a metal prep. Your LBS should have it. (if they are good)

throw it out and get a mech disc.

If you happen to accidently press the lever when the bike is upside down, the brakes will feel really mush afterwards. As with most other hydraulic disc brakes, it should come back to normal after pumping the lever many many many times when the bike is right side up.

I would clean the rotor with denatured alcohol and burn the pads till they smoke with a torch...I did this to a few bikes and it did the trick. Good luck

throw it out and get a mech disc.
That sums it up. I've run same pads for over a year through summer and snowy/salty winter w/o any huge detrimental effects.

your rear brake still doesnt lock up

Now that I've got a 8inch rotor it locks up better than your computer...

Bust.

Hope owns.Get new pads and a clean rotor and a fresh bleed.Wich reminds me I have to do all of those.

[seattletrials]

well as for leaving your bike upsidedown and having the brake not work. that would make your lever feel very soft, and wouldn't grab, which means you have air in your system and it needs a bleed. But if that's not the problem, and you have a very solid lever feel, I would suggest cleaning your rotor with rubbing alcohal, and sanding it, and cleaning it again. Then start off with new pads. Or if you don't want to buy new pads, use a candle or a torch, and heat up your pads from the back side of the pads, and that will create smoke that will rise up from your pads. That smoke is the oil, and contaminants that are in the pad compound. Once the smoke stops, then there's nothing left, and all there's left to do is give them a quick sanding, put them back in your brake and go burn them in again. (I've done it a few times before, so trust me, it works)

I got a drop of oil on my hayes while refilling the oil in my shock and it just ruined it. I bought new pads and although it prolly wasn't necessary, my friend gave me a spare rotor. If you get anything on the pads, they're basically gone.

[Matty]

I really want one of these mono trials for xmas but alot of people say there crap. Does anyone have one and like them???

~Matty :wtf:

[Ross W.]

well, mine seems to be getting better slowly. I haven't done anything to it as I'm lazy, just keep riding it. I have to say, I still much prefer it over the maguras, although I've never run vees, so I can't really compare there.

[KeepRollin]

Does it make more noise than it used to? I found if I got some kind of oil on them they groan something feirce. Usually putting water on the rotor and buring it off over and over again will bring them back.

[Ross W.]

It does make a groaning noise actually. Cheers for the help.

[Planet-X 92]

if there was salt on the ground that could affect it and perhaps oil that was left on the gound because oil floats and it could easily splash on the rotor.
