Do they just come off easily or do you have to strip the bearings out?
-
The bearings can stay intact inside the hub although it's good practice to regrease them before putting it all back together.
The disc should come off seperately without affecting the bearings but the whole hub has to come off the axle.

Thought so they arnt too bad so will just put pads in for now.
Thanks

As chris says no probs, easy job if you have abs you have to remove the ring I believe to get at the bolts for the discs, they can be tight, and you will have to anchor the hub to crack them off, I normally use a couple of spare wheels and drop the hub into them
As for the bearings, for what it costs for new ones, and depending on what you intend on doing with the vehicle it could be worth changing them while you have the hubs out

I have had to cut disks in half before to get them off, but I believe on the original RR at least that the front and rear had the same hub.
-
Just changed my rear discs this aft.
I had to use a hydrolic press to seperate the disc, it took 3t off pressure :shock: .
Every thing else was easy. Repacked the hubs as well.
All still in good condition, not bad as they havent been off in al least 4 years.

Are the front discs the same size as the rears :?:
Do they have the same Part No :?:

Er, good question.
On the RC the original rear disks wers smaller but had the same offset, so most replacement parts used the sane disk front and rear, which is why you see the rear start to rust around the edge.
But, I tried to fit a spare rear I had onto Tim's Disco 300TDi and although they were the right diameter etc the offset was slightly wrong so they wouldn't go in the calliper. Either the ones I've bought are duff or the front and rears on Tim's car are different. Haven't got round to checking though :roll:

Just done the discs on my mates 91 V8 disco with no problem at all. Discs on that were same diameter but had different offsets. Paddocks kits are very good and very cheap. Front Discs, pads and fitting kit £30 rears, £25 for a complete axle set.
I didn't have any problem removing the hub from the disc either, just a big hammer on the old ones.
Enjoy

Only thing I find wrong with cheap disks is that I have to change them more often. If you don't mind the work it's not a bad thing I suppose but if you find a juddering or wobbbling under braking it's because the cheap disks are not homogenious and have soft spots in the cast iron. As you take the surface off the soft spots don't wear as fast so the disk runs like it's warped even though it isn't.
