Graham - I've got a bearing spanner if you need to borrow it. Can always head through to Harties. Let me know.

Thanks Ian.
We're actually going to be in JHB for the week and a bit at the inlaws - wife is about to pop with our second child, so want to be close to the hospital.
Anyway, I mentioned this to the father in law (an engineer) and he says we dont need the tool, he knows what to do, and we all know not to argue with the FIL :lol:
He also reckons we'll get the new suspension kit in.
Everyone get ready for my emergency calls on the watsapp group in the next couple days! :rolling:

If my memory is correct , you need to torque those bearings to nearly 200Nm and it's not a castle nut or similar standard 6 sided nut, so unless he has another 2 pin adjustable tool in his toolbox I'll suggest you borrow , get one, or have Ant's Workshop number on call. :-

Hi Andries,

Thanks, I thought that 200Nm was only if it was for new bearing that needed to be seated properly, and not for existing bearings?
I have no clue though, so just checking?

The issue with cold brakes and Powerbrake is a fallacy..........

It is not the rotors that cause the brakes to only work when hot, it is the brake pads.

When I used to race, we used Mintex Metalmaster brake pads, they also only worked well when hot, but this was because of the pad compound. It contained more metal (copper and brass) to enable it to work better and actually survive at a higher heat. When I started racing in my Alfasud (inboard front discs), the normal pads used to turn into ash. This was not so much a problem in a 10 lap race, but in one or two hour races it was a total disaster to have to come into the pits to fit new brake pads.

Powerbrake has in the last year or two moved away from the Mintex pads and now use various compounds of the D-Line brake pads.

Powerbake rotors are locally developed and manufactured and are used across the world, often in racing and rally vehicles. They will not do heaps of research and spend millions of Rands on race performance products if they do not have a market for these and neither will they have the market-share if the brakes do not work to their customers' expectations.

Here are their details:

SUPPORT LOCAL PRODUCTS, MORE SO IF THEY ACTUALLY WORK.

I had them fitted to 3 vehicles so far. My current Y61 Patrol will get them fitted as soon as the discs need replacement

1. I had fitted a set of Powerbrake rotors on my Terrano in the early 2000s (2004 IIRC) and the first set of pads needed warming up. The second set of pads not. I fitted them on the Terrano at very close to 200,000km and when I sold the vehicle at 350,000km I still had the first set of Powerbrake discs fitted, they were not badly worn and were not warped. It still had the second set of Pads. I was suitably impressed.

2. I had a set fitted (front and rear - they actually specially manufactured rear rotors for me back in 2012, as they had discontinued them) on my Y60 GQ Patrol. I did not have problems with them as I fitted pads that did not need warming up.

3. I currently have a new set (fitted in August 2020) in my Pathfinder and find them exceptional. The pads are the standard ones supplied by them and do not require warming up

Malcolm - I agree with your sentiment regarding shopping local. I also believe PowerBrake products are good. However, Terrain Tamer parts are also excellent. Furthermore, I believe one of our forum members is the local distributor for Terrain Tamer parts.

So along with the following statement of yours.

Sorry guys.
Can anyone confirm, do I really need 200 odd nm when putting the bearings back?
Or is it not just the normal bearing work of ‘tighten till it feels right’?

Graham, I have found that, if you just tighten by feel, they get loose pretty soon after.

I suspect it's just pushing the grease out a little and one probably doesn't need the full 200Nm, but I have not experimented with how much one does need.

Not sure where in JHB you are, but you are welcome to borrow a spanner from me. Even though I feel it's something every Y61 owner should have in his tool box...

If it helps, I have to go to Auckland Park at some stage tomorrow.

Hello Graham,
I can join Peters opinion.
I have the same experience with less torque, it get loose again within a few Km's.
I tighten mine with 200Nm, the first time.
I also have the Spanner in my toolbox :-)

Have a nice one
