I've discovered that the problem we have with our relatively new Maclaren Techno buggy seems to be a design fault ie the brakes make the outer rear wheel wear down. Ours is now so worn that it's hard to steer. I've discovered two neighbours who have a similar problem and just wonder how many Mumsnetters have noticed the same thing with theirs. I'm going to approach Maclaren but would like to hear from others who may have similar problem first. Thanks.
