Thread: Drum Brake Salisbury In a Rangie

Are there any issues with running drum brakes off a disc brake system? I heard something about drum brake master cylinders and disc brake master cylinders being different...

And if there is issues, can the disc brake setup off the Rover axle be put on salisbury?

Not sure about the drums vs discs but apparently theres not much work in puting the rangie brake setup on the salisbury, i am looking at doing this for my 110, but apparently makes the rear slightly underbraked in a 110, couldnt see that being an issue in a rangie as thats what they come off!

I found most of the info in a post on outer limits, i will see if i can find it for you if your interested.

Yep sounds like a good idea tho i know who will be doing the lookin and who will be doing the doing

I'd be tempted to keep the Range Rover axle and discs as it is.

Yes..the salibury is supposed to be stronger but if it goes wrong out in the feild then you're pretty stuffed when trying to remove it from the axle casing. You'd need a case splitter to do that.
If building some strength into the axle was a primary concern then I'd be inclined to go down rally route and throw in some strengthened shafts, flanges, diff and also look at trussing the axle case via gussets.

I think I'm right in saying that to convert an early salisbury to discs you'd need a few bits from a late 300 series axle. (or get clever with the welder and fabricate some odds & sods) Alot of people have done it but I keep asking the question why. Our rally Defender was running a Rover back end, Quaife diff and half shafts etc, gusseted axle etc.
Keep is standard for ease of repair in the feild is always a concern too.

ANother thing to remember is that when building in strength to one line of components you'll expose a weaker link else where in the drive train. Been there & done that.... not cheap either.

Good evening, that is what we are having here, and about 20cm of snow.

Some of the swiss army rangies had salisbury drum axles fitted to the rear. one of does rangerovers is in the hand of a classic car collector, i got a chance to drive it a couple of years ago, there is not much of a difference in the way the brakes perform.

I planning on changing the axles front on rear of my 110TDI for a set of a 110 V8, i reckon they made em a lot stronger back in those days, and drums don't rust and squeal the way disks do at the moment, and are easy to change.

cheers Richard

I think you'll have to modify the brake master cylinder. The front disc/rear drum master has a check valve for the drum circuit - it's just a little brass thingy that restricts fluid.

I did a rear disc conversion on my Torana and had to remove this check valve in order for the rear brakes to work and then not stay on. Have a chat to a brake specialist on this...you might have to replace the master or have a valve fitted. You also might have issues with the RTA for 'reducing' braking efficiency - they might think going from discs to drums is a backward step (despite the racing history of drum brakes - but thats another story)

Good luck with it

No "supposed to" about it - the Sals is MUCH, MUCH stronger. 1.5" larger ring gear, much thicker teeth, and HYPOID.

Also - needing a case splitter is a furphy. You just need gentle pressure from a couple of tyre levers to remove, and a soft hammer to refit.

Discs will bolt up, but you need to mix-and-match some parts - like the bolt-on caliper brackets fitted to late 200Tdis, etc...

Sounds good to me.

Thanks for your input guys. I will fit one.

Just remember - the sals pinion is 2'' longer, therefore you have to shorten your Drive shaft the sam amount.

Cheers
Dave.
