When I was setting up racing drum brakes we'd put in two shims, one between each face of the brake cam and it's respective shoe to bring the shoes out to where they will be when the brakes are applied. We'd then grind the shoe material so that the shoe diameter exactly matched the internal diameter of the drum to get an effectively perfect, full contact between the shoes and the drum.
Are these CB400F clutch damper rubbers still available? I saw your listing on eBay a few weeks ago for 2 sizes but unfortunately it disappeared before I could order them
Great video i need to do this to a 2 year only ATV as when they were last skimmed they weren't round so its ruined them. I am at that point were i go do i buy the material or get a professional to do it who does it daily s surley get the cast cheaper than i can
I replaced the clutch basket bushings in my 1981 Kawasaki 305 using a similar idea. Instead of Teflon i used a liquid polyurethane and poured the bushing pockets full. After it sets up it's really tough yet flexible and works great. I posted the whole process in the Facebook KZ305 owners group about 2 years ago. The Teflon seems a great option too.
I used to reline hubs exactly as you have for a local post office contractor using Honda Cub 125cc motorcycles. They were really expensive & didn't last all that long. I was always concerned about the cast liner slipping, so I would screw cut the hub & liner with a 1.5mm pitch thread & screw it into the hub. Noting direction that the braking torque would always screw the liner in tighter against the back of the hub + filled it with locktite. Worked a treat, but it was time consuming & eventually just used OEM
Great job I watched you perform there was just wondering why no pic tite was used to keep new screws from coming back out was all...nice using Teflon wut right tools u had to create them ... outstanding everyone doesn't have that tool to make clutch basket dampers ...Honda doesn't sell them individually..I suppose they want you to buy entire brand new clutch basket 😁 lol
May I ask why you didn't add any loc tite to those new screws you used in place of the drilled out rivet holes? So they wouldn't back themselves out under load as bike engine vibrates when running ?
I've been looking for someone who can do this for me for a while, it's literally holding up my project bike from continuing 😢... I've got the hub separated from the wheel and sandblasted..I hope you could you fit a new break lining for me please? I'm London based but I work in Cambridge so I can drop it to you or ship it 🙏
Hi. Great, informative video. So I’ve just been quoted £550 to have two solid discs from an XS650 skimmed like yours and drilled 112 holes each. I understand the level of time and skill involved however unfortunately I’ve had to say no at that price. ☹️
g,day Max. can you reply back and let me know the dimensions for machining and drilling. I'm not a machinist but do have a small hobby lathe, no milling machine and a 1975 CB400 4 with no clutch. I am hoping I can use a drill press to slot out. Regards Eddie. Western Australia
Hi Eddie, i can send you the drawings for the rubbers, you can email me at amx92@yahoo.com. I think you might have trouble making the slot in pillar drill, im planning on making another batch in early january, if you need some.
G,day Max, yes another guy with a CB400 4 clutch basket damper issue's. Can you tell me where did you source your Viton cord and what size. Would you be prepare to share your machining details. Also how long did your Teflon dampers last, time and mileage? might consider using Teflon if I can't source Viton here in Western Australia. Regards EddiE Kirby
Thanks, those worn clutch baskets re really annoying. I got the viton sheet from a company called coruba, id be happy to share all the dimensions and the jig 3d print files if you want to get some made. The teflon ones only lasted about 1000 miles before they started wearing unfotunately
Brilliant job 👍 I have 1982 Honda xl 500 that requires this job. Where did you buy your cast from? And how much for someone to do this job for me. Many thanks
@@maxfh768 just reduced the brake cam just at the lobe and a touch before on the leading shoe contact point on the triumph. The brake feels a touch stronger as the mechanical action of the cam presses on different parts of the leading and trailing shoes. Only took about half a millimetre off but it biases it onto the leading shoe. First stage in the brake improvements.
A very nice job. I used to do drum brakes on stands in the parking lot, because I would pull drum and then wash clean with a garden water hose/ nozzle. No dust, and nicer to disassemble clean brakes.
Good job mate. Would you be interested in making some for customers? I would happily pay for them. Could be a nice job on the side. Nobody else is making the,.
Great job. It’s funny how those who cannot do this job always think it should have been done differently. Inevitably, they, themselves, have no YT tutorials. This is a great use of your tools and the drum doesn’t know what type of lathe did the job. Ive had a chance to get two, both free. Can’t justify for a diner with an engine lathe. A brake lathe takes a lot of space for the one job it does and you are right, most just wastefully replace drums and disks nowadays. For business the time of setup, measuring, and turning would be difficult to charge for when the customer always thinks that new is best. Kudos for saving and using serviceable parts. Rant over!
