Although I've been pottering in the workshop of late I've had nothing much exciting to report.
But I thought I'd show this ... Been working on my car quite a bit lately and one issue I had was metal on metal grinding on the rear brakes. It's not that long since I put new shoes on, maybe a year. So I didn't rush out and buy new shoes, instead I decided to have a look at what might be going on.
And don't you know it, those bl***y drums would not come off. There was me banging and levering away and would they budge! I'm sure some of you have been there and got the t-shirt. Well I did manage in the end and I was damn well going to make sure I didn't have to go through that again.
I'm sure most of you know what the problem is, it's the lip that forms as the drum surface wears. You have to force this over the shoes and it can sometimes ruin them if you are unfortunate. Mine were ok and as suspected they were not worn either. In fact they still looked new with plenty of meat on them.
So, first job was to remove this damned lip.

Centered up to within 0.001" on the RT and not only milled the lip off but took it a further 0.020" as well for future wear.

There then, that won't be giving me any more trouble will it

Now onto the original problem, the metal on metal binding noise. As I said the shoes were fine so we had to look for other signs of trouble. The only thing I could come up with was that as the drum rim had worn slightly allowing the metal part of the shoes to come into contact with the outer face (wheel face) of the drum as this was tapered at the very outer edge towards the rim. (you can breathe now)
So 0.050" was removed

Sorted, did both drums and the brakes no longer make any 'orrible noises and the drums slip on an off without a hammer in sight
