How to reline a motorcycle brake drum

Great video for old models

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.

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

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

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 🙏

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

Well that’s a lot more comprehensive than I thought it was going t on be! Very nice job. Is the brake still shite though! My 7” triumph drum is!

[@maxfh768]

The brake is a lot better than before, but still pretty shite. I guess drum brakes are never going to be as good as disks on the front of a bike.

[@highdownmartin]

@@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.

Or just put a disc and have better braking system

you could've replaced with dics brakes but ok good job
