rear drum hydrulic brake setup

[martinr]

heres somthing ive been thinking about for i while. ive got a rear disc on my cutdown so im used to decent braking. i just build a imola engine for my full frame lammy id forgot how s**t drum brakes are the main problem being when the cam is moved the shoes dont put pressure evenly on the hub one shoe tends to hit first and harder then the other. so if i could put a small slave cylinder in to move the shoes this would solve the problem so this what ive come up with



the first first pic is a mock up i did on an old casting the next two are on the scoot

Great to see it again martin, brilliant set up i know i will buy one when they hit the shops,
If your looking to getthem in production(which you should) there is some TOP TOP people in the scooter business members on this great site,

Good Luck martin..

so would this work the same on a vespa?

This is a top piece of work.
We just need somebody to put it into production, I'm sure it would be really popular.

Isn't that caused by dodgey indian cases not machined right?

[martinr]

yes that doesnt help .the good thing about hydrulics if one shoes hits first the other one is still going to move till it hits as well

[shocky]

id have one of these as well come on martin get in contact with someone and get them made maybe scooterloopyjohn would be interested his stuff is A1 and he,s a real nice guy a true scooterist ... he always looks grumpy at parts fairs though

[byron]

have you had to do anything to the casing ?
i guess you've shortened the shoes slightly ?
