Does anyone on here know if it is possible to have a rear brake drum relined.

I know the simple answer is to buy another wheel but as they are all so old (it's for a monolever G/S) I feel that the drum will be way past its best on any second hand wheel and a new hub is over my limited budget.
It looks like a simple operation to me if you have the equipment.

Any advise is always appreciated.
 
Surely you can order new liners from MotoBins ? Shouldn't be to expensive. Why would you need a new wheel or hub ? Might even do a P/X for your old worn liners.

I think you mis-understand my problem.
The brake drum is worn out not the shoes. The steel band that is a shrink fit into the alloy hub.
 
OK -sorry !! Still might be worth checking with MotoBins, Motorworks etc. But guess the main cost would be removing old hub, and having wheel re-built, which is what you already know !!
I'm sure someone on here will know though. Hope you get it sorted.

I think you might find that relining is not an option on these wheels. I'd be quite sure that the lining was fitted as part of the casting of the hub and not afterwords. It might be possible for a skilled machinist to Turn out most of the existing steel and then make and fit a new one. But with time costs alone I'd think it better value to buy a new hub.

re-lining a brake drum used to be.... no big deal in "the good old days"

turn the old lining out in a lathe
then "shrink" a new liner in.... (heat the hub/freeze the liner)

true the hub in the lathe and "skim" the new liner.....:thumb


not rocket science! any engineering workshop would do it for ya:thumb





but with all the "progress" of the last 30 years.....



good luck..

or just check the small adds in the back of MCN or Classic Bike mag

still a few old skool engineers out there:thumb

That was my thought exactly.

And as I was quoted about £400 for a new hub, then wheel building and the dreaded, the thick end of £500 to fix one drum brake that is definitly "old school" at best is just plain madness.
Unfortunately down here enterprising engineers seem to be lacking.

Thanks for substaniating my idea though How Much.

dont give up...

check the classic bike mags, check that modern fangle t'internet:D

its the Stafford clasic bike show 17/18th Oct.. these people are out there doing "proper" engineering" will see if i can clock anyone offering such a service when i go.....:thumb




how much
 
Thanks to Rob and How Much.

I now have food for thought and if you see anyone offering such a service at the show How Much I would be interested to see other options.
I will not be doing this job untill the winter so there is no immediate rush.

Thanks again Ian.
 
Hi

Saftek advertise a lot in the classic bike press, no direct experience but I plan to take the front wheel from my Rudge to them over the winter.

You can also get the drum built up by metal-spraying and then turned down to size but I don't suppose this is cheap. There is an article about the process in one of this months classic bike mags.

Cheers

Have you had the BMW hubs relined?
I always thought that this was impossible due the hub cast around the liner rather than a liner ever actually shrunk in.
 
BLR skim the drums according to their website. Must be a half decent company (for Southerners) though they have Jones and shipman tooling :cool:
 
I telephoned BLR yesterday afternoon but the boss is on holiday and the chap I spoke to said I was to ring back on Monday for details.
So I will update when I have spoken to the boss.
 
I spoke to BLR today and they won't reline the hub. He says the steel band is cast in and not replaceable.
So I will have to look for a second hand wheel with a good drum because mine is beyond skimming I think.
 
Theres a chap on Advrider, Phreaky Phil, who fitted an 1100 rear disk. I'll go down this route when mine wears.

Lovely machine work.

There's a lot more to it than a simple bolt on but he explains it in detail on the thread.
 
OOOOOOOOOOOOOOO:drool
That is so sweet, Does any one want to buy a couple of HPN rear brake conversions in the near future :D
