Managed a bit of progress towards getting the handbrake sorted. I have the same setup as jools is using on his car, which modifies the existing handbrake to drive the piston in the cylinder. First a bit of fabrication to create the pivot point from a bit of 1.6mm zintec sheet. Two halves welded together.
Drilled for the pivot and then welded on:
Welded on…
I’ve converted the handbrake to fly-off with a stainless steel pin made out of a bicycle wheel spoke. It has a L-shaped bend in the end that tucks in under the rubber to stop it falling out.
Test fitted. I need to fabricate up a support for the rear mounting next.
