Front Brake Torque Arm - 3D model

Quickly modelled ths brake bracket up in AutoCad 3d. Upper two holes mount to the lower fork leg, lower hole is where the brake cable goes through and the hole for mounting to the brake plate is hidden behind. Have used photoshop to emboss 'crispy one' on the only custom part so far. Part will be painted to match cylinder and the rear shock springs.

Original vs My Re-style

I think you would agree that my version (below) is definitely better than the original plastic fantastic!

Red cylinder

The overbored cylinder has no paint, so rather than paint the entire engine black, I thought lets just paint the cylinder red! Will be sure to paint the shock springs as well.

Front Brake Torque Arm - Drum to USD

Using AutoCAD I designed and drew up this torque arm bracket to connect the brake shoe backing plate assembly to the lower part of the left-hand fork leg. The red lines on the image show where it will go. The blue line shows the path of the brake cable. The cable mount will be coincident with the outer mounting point.

Vented front-brake scoop is now just a cover!

I have now decided that instead of fabricating a brake scoop and fastening it to the fork. It will just simply be a cover over the redundant cush-drive. I was concerned about the possibility of the scoop fouling with the front wheel and causing a front wheel lock up at speed! This means I have to chop the centre out of the enfield brake plate and figure out a way to fasten it to the wheel.

Vented Brake Scoop Part Two

Rather than try and make a brake scoop from scratch, I have photo-mocked up these Lambretta scoops to see how they look and fit. Available from India at about $20 delivered to my door. Should be able to bolt it to the brake plate with some allen-head bolts.

Vented front-brake scoop - Part One

Step 1. Remove unecessary parts from the part (brake shoe pivots).
Step 2. Reem out axle hole to suit KX front axle.
Step 3. Trial fit backing plate to see what else needs doing.

About 5mm needs to be added radially to make it match the diameter of the hub. A spacer needs to be made so the front wheel will also sit centrally in the forks. The brake plate will need to be reemed out further so it will fit correctly.
