Just wondering if anybody had done it before?
I've got half a tipper (i.e. everything from the cab back) which im turning in to a (off road) trailer and im going to convert the axle to have over-run brakes... Being off road it doesn't really need them but the trailer is likely to be heavier than than tractor towing it so it seems like a good idea. I can either find a trailer axle and put it on (which doesn't seem to exist with a high enough load rating with over-run brakes, and would stop me being able to convert the trailer to driven via the tractor PTO) or I can convert the transit brakes to over-run. There is of course also the factor that I like a challenge!
My research has revealed 2 main types of over run brakes, one where the action of reversing slips a "shoe" on the brake shoe to push it away (knott type), and the other has a cam which pulls the shoes away (alko).
The drums on the transit are 280mm dia, whereas the biggest set of brake shoes I can find for either method of operation is 250mm.
At the moment I have bought a pair of "slipper" type shoes, as the method of operation is much much simpler and I should be able to fudge them in with a bit of effort, cutting and welding of the shoes... but lets see what happens!
Any thoughts?
