Model A - Rear Brake Rod

 The rear brake rod is a much simpler affair than the front - it has a clevis at the rear end and this just needs a new pin, which is easy to make on the mini-lathe using a tailstock V-block:

The brake rod is just a bit of 1/4 round bar, threaded 1/4 CEI for the adjuster. The clevis is there, though very worn and we can find a spring from stock. The adjusting knob is missing, so we will turn that from a bit of 303 round bar, 1 OD:


It's reduced to 1/2" at the rear end, and the front appears to be domed but other than that is is similar to the front one. Same straight knurl:


Dome is made after parting off, with a combination of turning and a bit of filing:


We can mill a shallow groove in the rear to accommodate the clevis using an end mill.

Job done, though I think that clevis will need replacing.
