Rear Discs

Will the rear disc rotor and breaks from an early Range Rover fit on a Perentie?

Not sure about that, but might be worth looking at the 6x6 axle, might be an easier way to fit disks to your axle. Unfortunately the housings/axles are a lot longer but it may fit yours?

No they won't fit. The rotor is a different offset and the callipers are mounted differently. There are a couple of RFSV rear axles in the latest AFM auction. Also as Scary mentioned the 6x6 rear and intermediate axles have the same brake setup as the 4x4 rear axle so might even be worth picking up a 6x6 axle if they go cheap and getting the brakes off it, then you could probably sell the rest of it and get some of your outlay back.

RFSV rear disks are 90 fronts.. the only thing you will struggle with is the adaptor plate, LRA zero stock and $800+ each. but you could make some up.

Will the rear disc rotor and breaks from an early Range Rover fit on a Perentie?
Fitting disks to the rear of the Perentie will always have some compromises unless you use all the components from the 6x6 or RFSV.

The early Range Rover classic, pre 1984 has a larger diameter in the collar on the outside of the hub, which prevents Land Rover manufactured alloy rims being fitted, but this may not be a problem for vehicles with steel rims.  Late Range Rover Classic hubs are the same as Disco 1 hubs and have the same bearing spacing as the 110/non-disk brake Defenders.  The RRc stub axles fit internally to the housing and not cup over the axle housing like the 110.  The calliper brackets on the RRc and Disco 1 axle housings are welded on parts of the housing, not a separate bracket like the early disk drake Defender and RFSV/6x6 brackets.

While you could use the RRc rear calliper on a Perentie, the brakes on the RRc are underwhelming and many owners fit Defender callipers (front and rear) because the Defender ones have larger piston sizes.  It is also why the RFSV/6x6 and KLR conversions use the 4 pot 90 and Disco 1 front callipers on the rear.  (You can't easily use RRc front callipers because they have two brake fluid lines to each calliper.)

Disk brake Defenders have different halfshafts, different stub axles, different hubs (Disk brake Defender hubs have narrower bearing spacing) and different drive flanges, so unless you acquire all the components from a Defender with Salisbury diff there will be a different (20mm narrower) track width.

The compromise most people make use is to use Disco 1 or 110 front hubs and accept the 20mm change in the rear track.

The RFSV and 6x6 have a unique hub that retains the original track, original stub axles, original halfshafts and original drive flanges.  The callipers are 4 pot Disco 1 or 90 fronts and the calliper brackets are unique, but easy to fabricate as they are flat plate.  Now that I have mentioned the above, just watch the price of the disk brake rear axles at AFM skyrocket in price!    ;D

The KLR kit is designed to fit 110 land rovers with rear drums.  I am not sure what parts they use for this.

Those axles at the sales might look good, but most are rusty, don't have callipers or pads, some have very poor disks, so getting one for $200/300 you still might have to spend another $500/700 on new parts might as well get the KLR kit.

Those axles at the sales might look good, but most are rusty, don't have callers or pads, some have very poor disks, so getting one for $200/300 you still might have to spend another $500/700 on new parts might as well get the KLR kit.
The KLR kit, while they modify some parts and have spent a lot of time getting the rear track close to the front, it is still a compromise.  But is still a good option over rear drums.

The rear assemblies from AFM may be worn out, but rotors and callipers and always considered consumable items which need replacement regularly.  The important items are the hubs and the brackets which have to be worth at least a couple or three hundred.  After all once you have them it's all standard parts.

I dismantled a reconditioned rear assembly to send the Salisbury bits to WA and decided to use the wheel cylinders on 48-852.  As soon as I fitted them up, one cylinder started leaking so had to purchase another pair of cylinders.  So if you do buy a rear assembly, consider that you should get new rotors and callipers and have a greater level of confidence in them for some time.

First off, for those who haven't seen it, here's the RFSV setup.



The KLR kit uses a neat billet adapter. It really is a shame you don't see it after it's installed.

Yes the KLR kit is a nice bit of kit and the four bolt calliper adapter bracket far superior to the ADE two bolt design.

If I didn't already have the Perentie 6x6 bits I would definitely be going with the KLR kit.  8)

Yes I have.

As you will understand to go genuine you need
2 x post 1994 axle halfshafts (short and long)
2 x post 1994 axle drive flanges
2 x post 1994 Defender stub axles
2 x stub axle crush tubes
4 x new wheel bearings
2 x post 1994 defender rear hubs
2 x disk rotors
2 x Defender rear callipers
2 x defender 300tdi rear calliper brackets (they were welded in the puma)
10 x rotor mounting bolts
4 x calliper mounting polts
8 x calliper bracket mounting bolts

The KLR kit is significantly less than that and if you go Defender disks you end up with narrow spaced wheel bearings.

So you are saying the KLR rear disk kit is not correct and will not suit a drum to disk conversion?
