OK I thought - lovely sunny day, and my brakes desparately need replacing as they seem to be underperforming. Surely I can manage this task on my own. No I can't. I have a book beside me and I think I'm sort of doing it, but I tighten the bolt with the no 5 thing, till it feels tight... then I touch the brake block and it starts to move... tighten more.... it still moves ... have I not got enough brute strength? I haven't even got to the adjustment bit yet. And hubby has just texted to say he will be late back - and therefore will not want to be met by a demand to fix my bike. Where am I going wrong?
