Rear brakes

The rear brakes are quite serviceable, however, the lining on the shoes are wearing quite thin. The wheel cylinders are not leaking and the pistons are free to move. The brake drum is showing very little signs of internal wear although the outside is rusty. New brake shoes are to be fitted and seal kits for the wheel cylinders. The brake pipe from the wheel cylinder to the flexible pipe has corroded badly and was removed in pieces, so a replacement has been made from cunifer. Pictures shown are the O/S the same treatment was for the N/S

Brake drum removed, this was shotblasted, skimmed and painted with black enamel.
Wheel cylinder stripped down, the body was honed inside and painted outside.
Pistons polished with 2000 grit wet and dry paper, new seals and dust covers replaced.
Here we can see the broken brake pipe as well.

 All built up ready for adjusting cams and eccentrics.
Tool made for adjusting the bottom eccentrics so the shoes line up with the top cams.
You can use an old brake drum for this, but I think this is more accurate.
