kalkhoff Pro Connect - brakes rubbing

[Mattyduk]

Hi

was getting the bike out this morning and I overbalanced as I was wheeling it from the garage and both bike and I fell on the ground

When I tried to ride the bike, I could hear a rubbing sound. It's coming from the front wheel. The mud guard looks clear, but the brake pads look like they are touching. So I've left the bike in the garage for today

Any easy instructions to readjust the brakes as I've never done that before.

cheers

It might be worth slackening the front wheel off in the forks and then to re-centre the wheel between the forks. You might have knocked it out slightly when you fell.

I'm sure someone will be along soon with the Shimano PDF document that shows you how to adjust the brakes, should that be required.

I think this might be covered in one of our videos , because i had to refer to it after shifting the brakes when putting the bike into a car.

But, as ever, Sheldon Brown covers it too, under Centering Adjustment at Adjusting Direct-pull Cantilever Bicycle Brakes ("V-Brakes ®")

That worked for me!

thanks for the replies. I'll give it a check tonight

I overbalanced whilst wheeling my Giant a few years ago and my hand pressed the side of the rim. The brakes were rubbing after that but I had actually distorted the rim.
Hope yours is just a simple adjust.

had a go tonight. Took off the wheel first, after disconnecting the "noodle". gave it a good check and then reseated it and reconnected the "noodle back".

The wheel itself looks fine and centred.

The left hand side brake though was still rubbing the rim.

I tried to use the "spring adjuster" but this didn't seem to make any difference, and I thought the vertical metal struts (coming out of the spring adjust) could be tightened to provide more tension to one side, but they seem to have a bit of play on them.

So a bit stuck, with my limited bike experience. I've slackened the cable through the anchor bolt, so that the brakes now don't rub, but the brake lever has a fair bit of give in it (but the brakes do work).

I'll take it in to work tomorrow as theres a guy there who knows a bit about bikes, but if anybody has any other suggestions in the meantime. Other than that, it might have to take a trip to "Action Bikes" in Basingstoke

cheers

First check

Hiya,

I suggest first rotating the wheel and watching the gap between rim and pad. If this changes as the wheel goes round its something to do with the wheel & we need to start there.

On the other hand if the gap remains constant its most likely (although there are other more obsure possibilities) to be brake adjustments. So which is it?

Good luck,
Rob.

The trick is balancing the spring tensions Mat, not overtightening the one on the side that's rubbing but slacking off the opposite one at the same time to get balance.

Another thing to watch out for is the cable "dressing", any tiewraps exerting pressure on one side of the V brake.

thanks for the replies again.

Cycled in today and my Systems admin guy quickly sorted out ! It was as some of you have said just a question of adjust the springer screws, but obviously I wasn't doing it right in a dimly lit garage last night (well thats my excuse anyway)

cheers
