I've been having a go at finishing off the underneath of the van ready for an MOT sometime before winter....lol..
The main thing to finish off under the van is the handbrake system from the F150 foot brake to the std Transit rear brakes.
The F150 has a cable attachment and the Transit rear brake linkage is an adjustable rod type.
So i shortened the std Transit rod and instead of welding the fixings back onto the rod at the right length i ran a dye down the one side of the rod and attached a second hand brake adjuster from a spare Transit.
So no welding was done on the rod itself just a modification which wouldn't alter the strength of the rod.

Then i made an adapter which would fix to the F150 foot brake cable to the Transit hand brake rod.

Everything seems to work ok... you put your foot down on the pedal and it locks the rear wheels... you pull the clutch release mech on the foot brake and it releases the brakes....
I have replaced the cylinders (smallest dia) and the brake shoes on the rear and am currently making up new brake pipes for the axle.
The brakes do seam to be pulling on one side more than the other at the mo using the foot brake, maybe this will sort itself out when i put the pipes on and use the hydraulic brake system... or perhaps i should try to adjust the adjusting system in the brake drums... Best put the pipes on and bleed the system first tho.
One thing i did notice is that on the old brake cable that went from one side of the drums to the other, there was what looks like a small adjuster in the cable on the one side and the new cable that I've just put on didn't have this... Perhaps I've put an earlier cable on and not a MK5 one which is why the brakes are pulling on the one side and i cant adjust it.
I'll have to try and sort this when its a bit sunnier..
Cheers everyone.
