So I'm under the C-30 and see a device that the rear brake line goes into before it splits to the two wheels.
It has a cylindrical body where a lever is attached at the center.
The lever is then connected to 90 degree arm that is fixed on the body of the axle.
I can only figure that it reacts to the rear axle flexing upon a heavy brake.
But what does it do?
It doesn't look sophisticated enough to be an anti lock system, but I could be wrong.
Any ideas? Thanks!
