Hi GuysHi Dougie.
Changing a breakaway cable is quite easy. First of all go to you local Bailey dealer and purchase the replacement. By doing that you could well get a direct replacement part with a key ring type ring to attatch to the hand brake mechanisum.
The other version use's two u clamp assemblies to attatch the cable.
Apply the brakes and chock the wheels frot and back for safety.
Raise the front of the van as high as possible with the jockey wheel.
Look at the existing remains of the old cable and where it is fitted.
If the fitting is the key ring type its a simple task using a screw driver to open the ring and slide the old off and reverse process to fit the new.
If you have the clamp type, remove the old cable using spanners or a wire cutter/hacksaw.
Feed the new cable through the fitting hole. Lower the caravan and hook it to the car. Now just pull the caravan tight to the wheel chocks with the hand brake off, with the car. Attach the car end of the cable to the car, Using the first u clamp pinch the main cable and the tail with it and fit the clamp nuts.
Now adjust the cable length so that it doesn't drag on the ground or pulls tight on a tight turn. Using the first clamp in an easy to reach position tighten the nuts.
Now re-apply the brake and unhook the van winding the front up high again for easy access.
Using the second u clamp, fit that to the cable and tail leaving about 25mm between it and the brake lever thus creating a loop. Thighten the nuts of that u clamp. Now undo the clamp first fitted and slide it next to the clamp you have just fitted. tighten it back up with a spanner. Finally cut off the tail of cable left, leaving about 10mm spare sticking out.
Using the two u-clamps aid's fitting and also gives a double back up to avoid slippage of the joint.
The whole job takes about an hour and only uses standard tools available at any DIY store.
