Ello all.
My b'twin rockrider 500, with mechanical disc brakes has new problemos..
Noticed my front wheel was closer to the left fork than the right this evening after a 10 mile ride.. Quite noticeably.
The brake caliper is also mounted on the left fork, and the outer (moveable) pad was rubbing against the rotor.
I had just had the front wheel trued and front disc brake adjusted for this very reason so this was annoying to have happened again within a week.
I should add that the front brake doesn't feel excessively strong, ie I can pull hard on it and have no worries about going over the bars or even locking up.
I should also add that there seems to be a little play when applying the front brake on its own. If I apply the front brake and rock the bike backwards and forwards, there seems to be some slight movement from somewhere, however if both brakes are applied and I rock the bike back and forth it is as steady and firm as a rock.
I got home and loosened the QR and jiggled the wheel straight and retightened the QR. This seemed to solve the brake rubbing AND the wheel being off centre. But why would the wheel have moved so much in the first place?
My new worry is that under moderate to heavy braking during my rides, the braking or something is pulling the front wheel out of the dropout slightly on the disc brake side, causing the wheel to come off centre between the forks and causing the disc brake to rub.
I did go over some rough terrain, mud, dirt but mainly concrete and tarmac, and went over a few foot high drop offs and down a few steps, but I thought it would be all in a days work for the bike really, or that those drops etc would have pushed the wheel back into place firmly between the dropouts if anything.
Any ideas or advice? The quick release skewer is by design on the right side fork and has a groove/recess in the fork on this side where the QR lever can be closed. It seemed pretty damn tight, Ie. I had to grab the fork and the QR lever to enable me to close the QR lever fully.
I have read that front disc brakes have a tendency to pull the front wheel out of their dropouts, and also that standard QR skewers can be pretty crap.
Fanx all! I suppose in the meantime I'll ensure the QR is as tight as can be and on my 10mile ride tomorrow see if it happens again!
