larrythelarrikan has a roadhaven in his big shed with cable operated overide discs brakes....by no means a recent addition by the looks, I was very surprised when i saw them.

These are also available.. www.ebay.com.au/itm/9-MECHANICAL-BRAKE-FULL-KIT-TRAILER-CARAVAN-PARTS-/170632856054?pt=AU_product_Trailer_Parts&hash=item27ba82c1f6The reason i am taking an interest in these gizzmos is i currently have a 2Tonne overide coupling on Little 9ft 6inch rosie which weighs in at around 600kg and a bit fully loaded. I marked the coupling shaft 2 or 3 years ago with a pencil at 15mm increments .. to see how far the coupling shaft moves back into the coupling under brakes. I have a gap between the brake arm and the spring pad of about 10mm I have been all over the world with the van behind all sorts of tow cars .. Some with very good brakes.. some with .. what would be best described as average, I have locked the brakes up more than once due to boneheads dropping a lane change in front of me coming up to traffic lights . The first pencil mark out from the coupling body is still there .. never touched or smudged by grease..... Yeeeesssssssssss.. i do have the flip over brake lock out folded out of the way.. duuuurrrrrrrrrrr  Which leads me to wander just how much braking effort is being applied to the morris minor drums ( otherwise known as tobacco tins  ) on "Rosie " and.. leaves me wandering is there a lower tonnage rated spring ( less than the standard 2T ) that i .. or someone with a really big thingy for squishing coupling springs could fit in the coupling body to give less resistance and hence a more progressive movement... and... hence... more braking effect due to inertia on the coupling?? Thats it.. i have been thinking.. i am dizzy.. i need to lay down.. Bye fa now Reddo |

Hi Reddo.
I have overide operated disk brakes on the car trailer, which work a little better than drum brakes, but I have just recently picked up another van which has electric brakes. And OH what a difference they make, for the extra few bucks thay are miles in front of any overide brakes and I will replace all of my overide brakes to electric as needed. ;D ;D
Cheers.
Richard

hi all
back in the late '70s i towed a racing gtr torana to lakeside raceway in queensland with my vc valiant ute.
the car trailer had dual axles with cable operated 4 wheel disc brakes and for 99.9999% of the trip i don't think i used the car brakes at all, just relied on the trailer brakes to pull me up.
on one occasion, a farmer slowly pulled onto the highway in front of me and all eight wheel were locked up to stop hitting him, that accounted for the 0.0001%.
but, as richard suggested, electric brakes with a good controller will outshine cable/hydraulic disc/drums any day.
your decision.
