: 1985 110 sals rear - switch for RR outers?

A friend has an early 110, drum brake sals rear.
We also have a lot of RR axles (early 1972-1985)

He wants disk brakes

Thinks of swapping a RR rear axle for the sals. I warn him he should take it easy or upgrade the inners of the RR axle.

His new idea is to just switch the outers, from flange and out.

Problems?

We think to use the sals half shafts and drive members.
The only problem we see is the length of the half shaft, we rely on the hubs having the same "length".

Much better options.

You can do a bolt-on disc conversion to a drum braked Sals using all stock rover parts.

The early disc braked models had a bolt-on caliper mount. I have the PN somewhere...

Didn't find the part number - but found that the bolt on brackets cost about e36. Some more info on the conversion possibilities:

you can use-
defender bolt on caliper mounts (some 300tdi models had these)
county (drum braked 110) front hubs (machine 250 thou of face)
county (drum braked 110) rear spindles
defender rear callipers


get the drum braked salisbury,
pull the whole lot off,
but leave the stub axles in place.
get an ex 90 front axle,
remove the hub & stud assembly (this is the bit with the wheelbearing in that the wheels bolt to).
then buy a pair of the salisbury rear axle calliper mounting brackets
(used on the early disc braked salisburies
before they started making the casings with the calliper brackets moulded into them).
bolt these on,
then stick the front hubs onto the salibury stubs (they fit straight on).
use the front spacer thing (with the tag on it) onto the rear stubs. (it will be able to rotate about 10 degrees either way,
but it won't when everything is tightened up),
then adjust the wheelbearings as usual.
the standard drum braked salisbury halfshafts WILL fit perfectly.
i measured mine with the differential out on a salisbury casing and its exactly the same as with drum brakes fitted.

you need to fit either: rangie rear discs with rangie callipers (small pads though.....)

OR

110 rear discs and 110 rear callipers. much better, but more expensive,
the rangie callipers are <almost> 2 a penny.
they both share the same bolt spacing that fits straight onto the mounting brackets.

If you use the rangie callipers,
then you'll need to grind/cut/mill about 4 mm off of the brackets and callipers
(2mm off of each will do) to get the callipers to clear the edge of the disc,
so it may be easier to get the 110 brakes.

i've done the conversion on an axle that is going to go onto my rebuilt 90 soon.
just got to get the callipers milled a bit. i'll post some pics ASAP.

Whoa!
Hold it.
The guy we are talking about is the mother of all CB's.
Remember, he considered swapping a sal for a RR rear, just because it was available.
Parts we have on the shelf and umptillions of hours fabbing is ok, but buying new parts?
No way.

If you want to be as CB as possible, it is just as easy to make your own bolt-on caliper brackets. Just need to cut them from 12-15mm thick flat steel plate.

A mate of mine did 2 disc conversions.
One used RRC front discs, RRC front hubs, RRC front calipers (converted to single line operation), and home-made caliper mounts. This setup worked really well, except that due to the huge volume in the rear calipers, the pedal went hard when it was halfway to the floor.

The second used RRC front discs and hubs, homemade brackets, but early ford cortina twin-pot calipers (larger calipers than RRC rear - may be hard to find over there - but in OZ they are cheap, readily available, and pads cost e8 for an axle set). This setup had equivalent braking performance to above, but the pedal sat higher up.

Both setups used a volvo proportioning valve (which can be dismantled, adjusted, then re-assembled - externally adjustable valves are illegal in OZ, as I'm sure they are up there in Sweden). You should have plenty of volvos to scrounge valves from...:laughing:

I get the caliper brackets a CB prices new... Normally what I do in place of the spacer is mill off about .100" off the caliper bracket (lots o meat there) to fit the Rangie calipers and rotors... You can also use front/rear RR Suffix A hubs..

Thanks for the replies.
So, if I understand correctly:
the Suffix A hubs fit onto the Sals stub axles and the only minor difficulty is choosing caliper and fabbing/sourcinga mount for it?

Yes, exactly - can also choose which rotor you want to run and/or machine rotor to et the spacing you want.
