Electric Brakes

Mine were only 6mm new...

Thanks a lot for the replies.
I actually tried that with a battery directly connected to the trailer brake pins & both wheels were too hard to turn by hand. This is also the case when I use the brake controller override & manual handbrake. However I don't think it's enough braking to slow down the trailer.

I know what you mean about lubricating the brake starwheel adjustor it's hard to move.

When I put it on full I see 12.7v on the display & about 11.7v at the hubs..

If the magnet was connected when you performed the voltage test, the voltage at the hubs is good.

Offroad magnets (that's what you have) will draw 3 to 4 amps when fully activated. The magnet in the pic is contaminated and worn. I suggest you replace both magnets and machine the drum magnet surface. It will then stick like the proverbial.

Cheers, plenty of good suggestions from everyone here.
Yeah I think I'll just go buy new magnets, drums & new shoes, then I don't need to worry about it for a few years. All up will be $400..

The drums are $68 each so not sure how much cheaper it would be to machine the inside surface & magnet surface ..

Hi yeah I've got the 150 prado never had a 120. This brake controller worked in my previous car towing this camper but that was about 8mth ago. The wiring seems all ok I wired the brake wire to the tail light & the blue wire to the prado blue wire near the tail light. I'm pretty sure it's not the brake controller or car as I get 11volts 3 amps at each magnet.

did you use a bigger cable? i did on my 120 despite a localauto elec saying to save money by sing thin cable.

i also ran my earth cable in thicker cable. same with the towbar plug hotwire and earth there too. actually bought a 12 pin plug and socket just to get the thicker cables in including the blue electric brake cable. i also didnt use the supplied blue cable tied up inbehind the light, i ran my own which wasnt hard as mine was thicker. i also tend to think the more joins in any cable the worse it is and with a join at front before the controller i eliminated another one by running my own blue cable all the way. prob makes no difference?? jus ran thicker cables to ando plugs for van battery charging whilst on the go today

I remember reading (not sure which forum) that you should replace the cables to the electric brakes on the van to thiciker size just same as the earth and the fridge cables all for same reasons you run thicker cable for fridges, dual batteries etc. not sure if yor existing cable is ok on the camper, but presume it would be ok or at least good enough since it worked before for you 8 months back. most people run thicker cables on their cars and forget about the campers, vans etc. not sure if this helps at all in your case....

ps - why dont you try tow someone elses van or camper and see how your car and controller reacts to the different tow - cheers
