G'day

This has been covered before but i need some clarification.

I know that the hand brake cable needs to be swapped over, but what else needs to be changed? Do the brake lines on the disc brake diff bolt straight up to the lines on the car?

Whats the go with the master cylinder? Does it need to be changed or not?

Cheers

what car? If its XF drum to disc using stock XF discs then its all pretty much a bolt up affair I think.

Forgot about that,

Yeah its an xf wagon with drums. Putting in xf disc lsd.

Cheers

I had a disc brake diff from an EA wagon put in my 302C XD ute. It needed the XF 4 wheel disc master cylinder, because the proportioning valve is part of the master cylinder.

Never got around to changing the hand brake cable over though so I had no hand brake. Bad.

Yeah this is one of those questions many people ask, and simply yes you are mean't to change a vavle in the master cylinder, which controls the bais. But, i've been running my drum to disc convertion for 12 months, without changing it. all it does is lock up the back before the front, and normally you don't lock em up. So personally I'd leave it, but if your racing it or driving on the street like you are, change it. But offically i told you to change it ok.

But you do have to change the hand brake cable, which is a b**ch. so you'd need a wagon one... hmm... i've got a Fairland one.

Fairlanes of that vintage are built on much the same platform as the wagons (complete with leaf springs in the rear) aren't they? If that's the case the cables should be interchangable or am I completely off-base?

yea, you'll need to change the master cylinder and rear handbrake cables, ones from a fairlane should do the trick

righto

done the swap.
Got the diff ready before it went in the car. New lines, discs (slotted), calipers and pads.
The diff went in real easy. i had real trouble getting the lines to seal up, but after 3 hours of rooting around i got them sealed up. The hand brake cable i used was out of the same wagon the diff came out of. Put that on real easy aswell. The problem no is that the pads groan when your driving, i think is should stop when they have bedded in properly.

As for the master cylinder there is no difference between drum and disc ( so i now know). I checked twice. My workshop manual for the xf series (all models, sedan wagon fairlane and ute) and the computer catalogue at abs in croydon.
The wagons all come with the same master cylinder whether its disc or drum, same with sedans and the fairlanes. However there is a difference in part numbers between each different model (sedan, wagon and fairlane) but as for size of the master cylinder and the valve inside they are the same. Me and the guy at abs pulled to rooted ones apart and compared them.

The car stops like a dream, heaps better than before and now i know why. Both wheel cylinders in the drums where pumping fluid into the brake shoes, hence the grabbing and the not wanting to stop.

Now all i have to do is wait for the 330mm fronts to turn up.
