Rear Brakes shoes keeping tightening (1 Viewer)

[PaulGrant]

Hi there guys,

I am have some issues with my cruisers rear brakes. I have adjusted the adjuster rods to allow me to free wheel spin the wheels about 2 full revolutions. Sweet as!

I then go cruising. Now the mechanism in the drum works in such a way that each time the handbrake is engaged a plate ratchets the adjuster rod. So essentially each time the handbrake is engaged the adjuster rods tighten and that tightens the brake shoes.

After a while the brake shoes become so tight that I can smell brake shoes being fried!
When I lift her off the ground I can barely rotate the wheels.

This seems like a real sh1tty mechanism that keep tightening the shoes until they essentially burn out. I have even had the pin kit and springs come loose and disintegrate in the drum.

Any help will be appreciated.

I think the plate that spins the star wheel tightener is not supposed to engage if the brakes are tight enough: it should be self regulating. Could the plate be installed backwards such that the leading edge engages every time instead of gliding over the star when things are right?

I have heard of that mechanism not doing its job but this is the first time I have heard it works too well.

Well mine works like a bomb!
See attached photo. I just have to move the brake level half a ball hair and the ratchet engages!

Watch video on how sensitive the mechanism is.

Exactly which model is it? The system works fine normally. Assembled incorrectly or some parts are missing is my guess.

I have the same problem. Can't work it out. At the moment the adjuster is super glued to stop it other wise the wheel will lock up. I am about to replace everything within the brake hub.

Handbrake cable tension? It may need to 'preload' the system? (I'm guessing here)
