Not nice, we used it by the truckload when maintaining gas fired boilers. Have an old business partner dying of it now too.

Remains a shame we learn about such dangers, after the fact.

But still, chuck them back in as they are Paul. They are probably good for another 50 years. While unkind, it works great.

The danger of a regular contact has been known for a very long time. I was told about it early 70s during my medical studies but people were still working with asbestos and we were using it in the buildings we worked and lived in.

Same goes for tobacco.

When money is involved, it takes more than knowing to change things.

didn't mean to stir the pot re asbestos issues, sorry about that. Unless I find a local brake relining service I am going to try to use the existing brake linings/shoes as they are and see what result is obtained. One pair of brake shoes is bonded, the other pair are riveted, one pair has a lot more shoe to inner brake drum clearance than the other pair. Only way to find out if either or both pairs are useable is after the bike is back together and running and take it for a ride...... I will put the better pair of brake shoes in the front brake
 
The main issue with excessive clearance Paul is that the shoes have to travel so far before contacting the drum that the cam angle becomes acute and the rotation of the wheel acts as a servo to pull the shoes 'on'. It's the classic drum scenario of a super sensitive lever and from 0 to 'too much' or lockup as soon as the shoes contact the drum ... usually associated with a loud squeal. Always worse when cold or in damp weather - and oh so much fun in the wet.

Excessive rotation of the cam can be mitigated by by a couple of methods.

Some may consider it a bit of a bodge to get more life out of worn brake shoes, but fitting shims between the cam and the ends of the brake shoes is a reasonable thing to do if they're made properly. The shims can be made from steel sheet and formed to clip over the ends of the shoes where the cam bears. The only caveat would be to avoid material that's too thin. You want them strong enough to clip firmly over the ends of the brake shoes. The tension in the springs holds them in place but if they're too thin they could deform and become dislodged. If the brake shoes are cast aluminium, they'll most likely already have a steel cap on the end as a hard-wearing surface for the cam to bear against. It'll either be integral with the casting or a separate clip-on fitting.

An alternative with steel shoes is to build up the ends of the shoes with weld then grind back to a flat surface. The same can be done to the cam too if it's showing signs of wear.

If your old brake shoes are contaminated with oil or grease, apparently baking them in an oven can restore them. I've not tried it myself, but according to various internet sources, the usual recipe is 20 mins at 200C (400F).
 
I used to soak oil contaminated car brakes shoes in gasoline, put them on the driveway and light the match, same with oil soaked clutch discs, all I could afford. Seemed to work, nothing got warped that I could tell.

moving on from brake shoes until the bike is running and I can try the brakes, I am fiddling with smaller bits, new hardware, cleaning and fitting things. I am still waiting for the return of the bits being painted, and availability of the fellow who is going to teach me how to build the wheels properly, with correct offsets as measured before disassembly.

put the handlebars and fittings together, freshly show chromed handlebars, straightened and polished original levers, new hardware, disassembled and cleaned original SuperPractic B throttle assembly, Gilera branded grips, and Verlichi bar ends. Both original levers were quite bent, padded the ends into a vice, heated them with a hot air gun, slid a pipe over them, and slowly slowly straightened them out..... bike may not be fast but will be pretty....;)

ps Stu - with my history of a recent catastrophic garage fire, can I bring my brake shoes by your place for service........:cautious::cautious::cautious:

I had to google "grip puppies". I must be getting too old.

Coincidentally, I was talking to a mate the other day who put something very similar on his Ducati. He was feeling some tingling or numbness in his hands and thought they might help. His assessment of them was that they achieved nothing and were a complete waste of money.

When I bought my Kawasaki Z1300, it had massively thick foam hand grips on it, about 50mm in diameter. It's a 6 cylinder engine that's as smooth as silk. There's no vibration through the bars at all, so I have no idea why the PO felt it necessary to put such big soft pillows on the ends of the handlebars. They had fake (plastic) chrome end caps with the Harley Davidson logo on them. They also felt weird in my hands, so the first job I ever did on that bike was to chuck the embarrassing Harley grips in the bin and replace them with something sensible.
 
I have had Grip Puppys fitted over my Oxford Heated Grips for a few years, I am on probably my 2nd set. They work very well at reducing the effects of vibs and nub hands-on long days. I use the Grip Puppies designed for 25mm Harley Handlebars so they go over the heated grips. They can tear easily. The std ones go over std 22mm bars and grips fine. I think they make Red ones as well. The heated grips still work well.
 
Hi Cam

at age 67 I have arthritis in both hands, worse on the throttle hand. I have tried everything I can find to make extended riding of a motorcycle still possible, and have a large box of discarded handle bar grips of various sizes and materials. These days sadly I have trouble closing my right hand around a normal size grip.

I am currently running the "Grip Puppies" over the stock heated grips on my supercharged and further modified Kawasaki H2 SX SE. They are the only thing I have found so far (still looking) that give my hands enough relief that I can ignore the arthritis and ride the bike as the bike is intended to be ridden. A set will wind up on the Gilera despite how stupid and out of place they will look....... They are cheap, easy to put on and take off, and best thing I have found so far for my particular problem. Probably not for everyone, but they are working for me.
 
What helped reduce numb hands in my 3C was Red rebuilding my crank but before that, I used these Gel padded palm Gloves and they helped a lot. It was so bad on long rides I would lose all feeling in my hands especially the right one till I started using 2 accessories, one of those plastic gadgets that allow you to just use the weight of your hand to hold the throttle on, CrampBuster and a Crusie Control. The latter uses a Cramp like gadget to hold the Throttle on and lets you shake your hand a bit.

Bugger! That's not good. Other than supposedly gaining wisdom, there's not a whole lot of good things about getting old. Even the wisdom disappears when you get dementia. I suppose the only positive spin you could put on old age is not being dead.

I turn 71 next week, and so far I seem to have dodged the bullet of arthritis. Although I don't feel as comfortable on sports style bikes as I used to. I reckon the day is soon approaching when I'll have to call it quits with clip-on handlebars and high rear-set footrests. My Jota (among some other bikes) will be looking for a new home when that day comes. :(
 
I just jacked my bars up 30 or 40mm and lowered the pegs the same. I tend to forget how old I am, a bit like that old conundrum when the millennium occurred, was it the end of 1999 or the end of 2000. I did the maths the other day and I am 65 this year, somehow I lost recollection of 2 years marking time over the Pandemic.
 
Well, bugger me sideways! I was just rummaging through a box of Kawasaki parts when I found these. I didn't throw them out after all!
The logo on the end caps isn't Harley either (hello dementia), its an eagle with the slogan "Live to Ride, Ride to Live".

Happy to donate them to your project Paul if you want a little bit of extra bling. :)

G'day Paul,
66 this year and have similar symptoms in my hands and carpal tunnel symptoms in my wrists.
I have fitted grip puppy's to 2 of my bikes and find them easy on the hands, vibrations are still there but don't seem as intense.
I have a pair similar to the grips that Cam has without the logo on the ends for 7/8 bars and find them just as good.

They make it bearable to ride long distances.

Cheers Ian.
