Squeeling like a b***h!!!!!!!!
Discussion
OK, I'm getting some fantastic trail riding with my new Stumpjumper FSR, but I've got a couple of issues with the setup and I was hoping for your help.
Firstly....the brakes. They are seriously powerful compared to my old Hayes 9's but they squeel like a total b***h and in normal road riding, they are either on....or off making the bike judder quite insanely. Is this to do with the power or is there something loose? I've checked the disc mounts and most of the other bolts, but it all seems ok.
Ideas?
The second thing has got to be the fork maintanence. What's the best way to maintain a Fox Talas front fork? I've heard from some people I should rub fork oil on the top tubes to help lubricate the seals and reduce friction. It also helps keep the rubber supple and therefore last longer. Is this the same with the rear shock too? (Fox Triad).
Cheers,
BB

Take your bike back and get them to face the surface of the disk mounts - although this may not cure the squealing, it won't do any harm to rule it out.
Once again, we'll go back to the "Stop being a jessie and use them properly" mantra as squealy brakes 'usually' come from the faces of the pads being glazed...

Watch it! I was heading down near verticle drops in pouring rain with every inch of ground breaking up beneath my wheels. I managed to get to the end putting my foot down once, but my housemate isn't so competent on these things and ended up somehow coming off his Y11 and ripping his shin to bits.
Now he doesn't follow me down the trails! hehe! diddums!
But back to the brakes...what do you mean by facing the surface of the disc mounts? I have to know how to explain this as the guys in the bike shops here speak English, albeit very poorly!!!

they should have a tool to do it (probably a Park one if they are any good).
Hang about I'll scan an article on it for you...
If you are getting squealing brakes they are probably contaminated. This is done by just about any slution known to man, - grease oil, cleaner,degreaser, bike lust, polish, Muck Off. They are all a total NO NO in relation to your discs. Dont get them anywhere near them. Now you can buy special disc cleaner for your discs so they can be de contaminated but usually your pads cant. They are not something you want to get contaminated. If your disc caliper needs facing then that is something your bike shop will have to do. To be honest the best shops are supposed to do this as part of teh PDI, but dont go in there hassling them as sometimes when they are busy it is something you can usually get away with noet doing.

Definately not contamination! I know how to look after brakes as I never had this issue with my hayes or any of my motorcycle brakes.
I think Neil has the right idea so I'm going to check out how if I can get the surface mounts faced as he suggested.....we'll wait and see....

One trail fix that always worked for me for the squeaks was cleaning the disc with a clean part of my glove. Use a quite a bit of pressure. Always seen to do the trick for me.
Can anyone shed any light on the theory of a light rub of sandpaper accross the face of the disc (i.e. not radially) as a cure? Never tried it myself as I'm afraid I'll ruin the discs but the theory sounds solid enough.

As far as fork maintenance goes, the Talas manual suggests storing the bike upside down to keep the seals fully lubricated, but its not something you need to do every time. Apart from that, a wipe over the stanchions with a clean cloth to remove any dirt / grit buildup after each ride and possibly another wipe over with a few drops of fork oil, but if the current terrain is dry/dusty its probably better to leave the stanchions fairly dry otherwise dust will stick to the oil which will build up in no time.
