V Brake Woe

carl_p

My first post in the MTB section so please be gentle.

I'm a roadie and know little about v brakes. Today I switched tyres on my MTB to Knobblies to get a few miles on the dreadful roads etc. What I did was release the noodle so I could get the wheel in between the brake pads only to discover that when I reconnected it the brakes were far too tight and rubbing on the rim. Is it necessary to do a full adjustment every time you release the noodle, or is there something simple I'm doing wrong?

Many thanks.

Check that the end of the noodle is clipped fully into the noodle holder (about 3/4mm of the end of the noodle should poke through):

has the outer cable come out of the barrel adjuster on the brake lever end?

also is it (outer cable) correctly seated at the pipe end?

Is the pipe correctly seated in it's mount on the V brake arm itself?

Yes it did come out and the cable went really slack. Probaly because I sqeezed the lever when the noodle was released? :oops:

The rear brake was working fine until I released the noodle, but as soon as I reconnected it, it all went wrong. As far as I can tell the noodle is seated correctly in the holder.

wheel not back in straight?

are both tight? eg is one caliper rubbing and the other not? To answer the question, removing the noodle from the noodle holder and replacing should not effect the brake at all.

V brakes often centre poorly so run on one side only. but if both sides.

check the cable at the brake end as well, and all the stops on the frame, the outers might be loose somewhere.

the solution of course is disk brakes, they never have this problem, just completely different problems.
