Rear Brakes

[Martin6]

I rang around a few engineering firms, who wouldn't touch it.

However, one local to me, asked me to drop it in, to have a look. They were worried about choosing the correct lining material and safely securing the new lining to the hub, without damaging the hub. They recommended a decent used one. On ebay I spotted this one.

I checked it is compatible with a K6 and condition. Hopefully, fingers crossed, this will be right. The vendor is local and happy to guarantee fit. Should be here at the end of the week.

I'd have to break the current wheel down to have it machined anyway, then build it back up, so no difference. Is there an offset I need to build into the rear wheel? I have done a Norton front wheel last year, so i know I'm in for some fun . I'll be aiming to reuse my nearly new spokes and rim.

Again, thanks for the advice, I'm hoping this route might be more simple.

EDIT: meant to add, from the link posted above, Stotfold Engineering told me they no longer do re-lining after the guy they used retired.

Bet that wasn't cheap.

[Martin6]

Not awful, but still £100 + postage. I think I'd pay more than that to have a re-lining done, if I could find somewhere. But, £100 I could have done without spending. All in, probably a lucky find.

I'm hoping I can do the wheel myself, to keep a lid on cost, so I can enjoy the bike this year, before the next round of improvements.

Anyone got info on run-out for a K6 rear wheel?

That’s a good price if it’s a good un.

[Martin6]

That’s a good price if it’s a good un.

Yes, that's the risk. OTOH, looks better than what I currently have (in photos!). More pics attached. I'll post what I think, once it arrives. Just realised I'll have to wrestle with the old cush rubbers...

Could do with anything anyone has on wheel run out. So, I have a spec to aim at.

No offset on any Honda CB SOHC/4 wheels

[Martin6]

That's good news. Thanks.

Whilst on the subject of rear hub relining, Trigger (Graham) has also recently stopped doing them as well. He had quite a big batch sent in to do a few months ago and some for forum members and they have all been sent back out.

Was the hub new? if so that's a really good price.

Was the hub new? if so that's a really good price.

No, used. Only have the photos and the vendors ebay feedback rating. I'm hoping, will find out later this week. Not touching my wheel until it arrives and I've measured it.

The replacement hub has gone on. It was as good as the photos and a first ride showed smooth progressive rear braking, with new shoes.

Spoking and truing the wheel was straightforward. Used the rear axle in the soft jaws of my vice and a bent coat hanger, as a guide. Just patience, take it in small increments. But removing the old tyre and fitting a new one (Avon RoadRider) was a real bear of a job. I still need to do the front tyre...

Good news on hub and wheel build.

Fitting tyres, rub some silicone grease around tyre bead, both the seat area and the backside (inside the tyre wall) before you start. This is literally the minimum amount spread sparsely over the whole circumference such that its almost invisible.  They pop on easily then, and seat properly with no hang up/alignment struggling.

I was using diluted car wash in a spray bottle. Not good enough. I've bought some proper tyre soap to use on the front wheel from a local motor factors. They only had a 5kg tub. I hope I find other uses for it, or it lasts 20 years (and me with it!).

I had my money's worth from a local bike shop who advertised 'free removal and fitting on loose wheels' . The tyres on my CB900 resisted them for nearly an hour...they finally gave up and used a hacksaw to cut them off.  Like dust inside. I'm glad I didn't ride on them! 

I think the new ones went on more easily than the old came off.

I had to cut my 40 year old tyres off my Lester wheels, Jesus they'd gone rock hard.
