Brake disc hub nut torque settings?

[Barney626]

About to replace the rear discs on my 197, struggling to get a consistent figure for the torque settings on the rear hub nut.

Some say 170-175Nm others say 280Nm.

Am I right in saying 280 is for the front Hub nut and 170 is for the rear hub nut?

Cheers.

175nm for the rear hub nut mate. 280nm is the front as you have deduced.

Bit odd that the new rear discs say tighten to 280nm...

Quick Q, are the hubs on those pagid disks coated? I'm toying between those and some mtec ones at the mo. I'm guessing they came with bearings and abs rings etc?

Also I'd stick to 175Nm, you don't want to strip the threads on the stub shaft etc.

I did my genuine renault rear discs to 175nm mate. Very strange

just looked at all the tigtening torques from the cup racer and it states rear hub nut 220nm with the front at 280nm

Service manual shows 175Nm...

Cup racer has different rear wheel bearing sizes, so that'll be the reason why.

nothing in specs about differences in wheel bearings or brakes...perhaps they dont want the wheel/hubs to come off in a race lol

Deffo different mate as a good friend of mine had one.

Could it maybe be different for various brands of discs?

Just strikes me as odd that the pagid discs specifically say 280 for the rear, maybe different torques for different brands is all I can think of?

 

[Northloopcup]

I can't see it tbh mate. The torque is used to preload the bearing. Too much or too little will cause premature bearing wear.

Some pics of the pagid rear discs if anyone comes across this in future and needs it:
