Brake Problem ? Frame Flex ? Help !!

SuperCove

Afternoon...

I have been scratching my head for a little over a brake problem I have.

When turning into a sharp left hand bend by front brake starts to drag alittle, most of the time it comes off once I straighten up but on some occassions it will not clear for some time.

I was wondering what could be causing this as one a long ride it starts to really sap energy.

Do you think it could be flex causing the brake to come on slightly... but not religning properly after the corner?

Any ideas?

what is the fork? what is the hub? what size discs?

most likely to be a flexy fork or play in the bearings.

The fork is a Fox Float 100 RL

Brakes are Shimano XTR M975 running a 180mm rotor.

The hub is a Shimano XT M770 (32 hole)

try adjusting the bearings. and then reset the caliper.

Thanks... I'll give it ago.

I hope it works as I agreed to do 25miles with a mate on Thurday and do not fancy trying to ride with a dragging front brake again!

Just a thought but im no expert
If its a fork flex why would it only happen when turning 1 way?
Whilst fork flex may be a factor something on the 1 side of the break calliper isn't right:-
allignment, uneven pad wear, sticking piston maybe even pad contamination...

PS wots the rest of your handjob set up Matt, my m8 swears by his as a Single Speed so gonna build mine up as SS for the summer, gr8 frames though, suprised they don't get more recognition

I can not fault the frame in anyway since I bought mine about a year ago!! Just started riding alot more and love it...

I guess I run mine as a XC set up... The fox forks, XTR dual control levels, XT chain set (as I somehow managed to destory my XTR one on a rock and robbed it from my other halfs bike... ), XTR front and rear mechs, carbon bars and seat post.
