Durano Plus Failure

[raleighnut]

Brake blocks or a faulty tyre? I use these and I haven't had any problems with them, their puncture resistance is impressive, when I do my weekly check I'll have to have a close look at mine. Many years ago I had a faulty tyre where that had happened, I cant remember the make now, but it made an impressive bang when it failed, woke up the dogs on the farm a hundred yards away.

The phenomenon only occurs with twin pivot brakes including 'centrepulls', all they need is repositioning when half worn

My money's on a combination of brake block positioning, and the fact that I weigh more and I carry a bit more gear than most so the brakes have a bit more work to do. Maybe my braking technique too, but if that's the case ... pah.

Your initial fitting may well have been perfect.

I had a problem like this last winter and it turned out to be wear in the wheel bearings letting the brake blocks rub the tyre. That kind of damage is usually the result of brake block wearing the sidewalls.

Yeah, my experience happened with mafac racers centre pulls... but user error was also to blame that time.

How did that work? What sort of 'wear in the wheel bearings' would "let the brake blocks rub the tyre"?

How did that work?

There was a lot of play! When I replaced the bearings they came out in bits.

Bloody users. Can't they get anything right?

Haha, not very often the first time, in my case!
