stoozie Posted April 3, 2009 Report Share Posted April 3, 2009 Whenever I brake my Hope lets out a really high pitched squeek. Anyone know of any way to stop this? Or do I have to put up with it Quote Link to comment Share on other sites More sharing options...
Muel Posted April 3, 2009 Report Share Posted April 3, 2009 What rotor have you got? I had a Gusset one and changed it to a Mono Trial and it happens less, but still happens.It didn't happen at all with my 160, just on the 180 I've got now.

stoozie Posted April 3, 2009 Author Report Share Posted April 3, 2009 (edited) A 160 Hope rotor.Is it something wrong that I should worry about? Or is it something that just seems to happen with them? Edited April 3, 2009 by stoozie Quote Link to comment Share on other sites More sharing options...
Muel Posted April 3, 2009 Report Share Posted April 3, 2009 Nah, just forget about it. It might have something to do with the forks, I'm guessing it's a stock wheel?It might be that you need to apply more pressure to the pads because the ratio between rotor and wheel size is much larger than when I had my 160 on a Mod.Maybe try a 200?

Captain Scarlet Posted April 3, 2009 Report Share Posted April 3, 2009 A 160 Hope rotor.Is it something wrong that I should worry about? Or is it something that just seems to happen with them?I would say that you need to face your brake mount.If there is excessive paint or metal on your brake mount, it doesn't allow for the calliper to sit exactly parralel with the rotor (which is very important).Of course what happens there is that a small amount of pad contacts the rotor first, followed by the remaining pad. (Much like with standard vee brakes on £200 mountain bikes, if the pads aren't set properly square it can create the some kind of squeak).Hope do a mount facing tool, which slips into your drop out and essentially files away at excessive paint or material to create a perfectly parralel mount.Most specialist bike shops will carry one.On a related note, what is your wheel alignment like? (is it front or rear brake) if its your rear wheel then it may not be central so the rotor itself isn't parralel to the calliper. Quote Link to comment Share on other sites More sharing options...
stoozie Posted April 3, 2009 Author Report Share Posted April 3, 2009 It's a front wheel. I'll take it to a shop I know near me which may have that facing tool you speak of when I go riding in town this weekend.

JT! Posted April 3, 2009 Report Share Posted April 3, 2009 I wouldn't bother. Just keep riding, it'll go away on it's own. Mine did.Is it new? Quote Link to comment Share on other sites More sharing options...
stoozie Posted April 3, 2009 Author Report Share Posted April 3, 2009 I bought it off someone on here, so it's second hand. Quote Link to comment Share on other sites More sharing options...
AdamR28 Posted April 3, 2009 Report Share Posted April 3, 2009 Could you try and describe the squeal a bit more please?It's either:Working perfectlyContaminated Quote Link to comment Share on other sites More sharing options...
stoozie Posted April 3, 2009 Author Report Share Posted April 3, 2009 Basically, whenever the pads hit the disc, it squeels until I let the lever go, only happens when I brake, whether it be lightly or heavily. Quote Link to comment Share on other sites More sharing options...
Ali C Posted April 3, 2009 Report Share Posted April 3, 2009 is it a loud deep squeal (almost a honk)? or is it a really high pitched squeal? Does the power feel good? Quote Link to comment Share on other sites More sharing options...
stoozie Posted April 3, 2009 Author Report Share Posted April 3, 2009 It's really high pitched, (scared the hell out of people when I braked at the end of an allyway yesterday). The power hasn't changed at all, still really good. It's just the noise, I want to know if something is wrong, or if its just something that happens Quote Link to comment Share on other sites More sharing options...
Muel Posted April 3, 2009 Report Share Posted April 3, 2009 It'll be fine, as long as it's working as it should then it's alright. When it's contaminated it can make a much lower honking noise. (Only happened to me when the caliper seals blew.) Quote Link to comment Share on other sites More sharing options...
