Have tried sanding the pads and cleaning pads and rims with degreaser but no joy
Anything else I can try short of replacing the pads?
Make sure the front of the pad hits the rim 1st, new brake blocks normally have a couple of 'pips' at the back so you can get the angle right.
BITD a strip of cereal box stuck under the last cm of block then lined up againt the rim worked well.
Thanks!
As MikeG says but I use a posties rubber band with a knot in then slip it over the back of the pad so the flat side of the band sits between the pad and rim. It stays in place unlike a piece of card that can fall out if you dont keep the pressure on the pad.
Red post office rubber band works much better as you don't have to hold it in place, [url= http://www.parktool.com/blog/repair-help/linear-pull-brake-service-v-brake-type ]Park Tools[/url]
Thats a good link, I've never used a laccy band but will give it a go next time I have to adjust the commuters brakes.
I do use a laccy band to pull the brakes on while adjusting, much easier to get them square if theres a bit of tension holding them against the rim (and it saves having to have 3 hands)
