Which ever way you go you can easily whip off the drums and give um a lick of paint when it finished scraping .
The tiny difference between the backing plate and the edge of the new drum. Mine too were rubbing like the chaps on here, but the spacing cured it. Only by a fraction, mind.
That would move the backing plate closer to the drum. Plus the backing plate would be on the wonk The only way you could move the drum away from the backing plate would be to fit washers over the studs before you fit the drum But if you do that there’s a chance you’ll snap the studs and you will have vibration problems
Then I did it another way. Like I said. I would have to look. There are no washers on the studs. That’s as silly as greasing them…
I think you're making it up mate, as Para says the only way to space the drum and backing plate further apart is spacers under the drums.
There’s only two ways you can fit washers whilst assembling that lot. Either between the backing plate and the bearing carrier. But that would put the plate closer to the drum along with a chance of snapping the bolts under heavy braking or Over the studs before the drum goes on That would space the drum out but the drum won’t be sat flat and the wheel studs will be taking all the rotational force of the wheel and are likely to snap. I can’t think of any other possible way you could fit washers?
Like I said…I would have to look. But they were definitely rubbing and I definitely cured it somehow without bending anything…
I think I'll just stick to the traditional method vw owners have used for donkeys years and let them bed in on their own, but cheers for your ideas @Soggz Sent from my SM-G981B using Tapatalk
Don’t blame you, I’ve probably mis led you on my idea. Perhaps I’m wrong. It was a while ago now, and I would have to look. But they did scrape, and I did fix it.
I've done the t25 rear brake conversion on my 79 bay and pretty sure the drums are slightly different than the bay ones. Are you sure you weren't sent the wrong ones? Pretty sure it was around where the backing plate goes into a groove on the drum (or the other way round) Admittedly, mine has only moved around 50 yards since doing this approx 4 years ago but there was definitely no scraping. Looking at the part numbers, the bay drums are 211 609 615 where the t25 drums are 251 609 615
Yes, mate, although Brickworks sells two types, the OEM ones and the Febi ones are what I bought. Sent from my SM-G981B using Tapatalk
Just let them rub, mate. My new (Bay) backplates made a terrible noise when I first fitted, but after a few miles of rubbing they quietened down. Unlikely to rust a lot, as the heat from braking will dry them out. I wouldn't put spacers in as, as @paradox says, you're potentially putting a point of leverage on the bolts.
