michael100 Posted October 13, 2008 Share Posted October 13, 2008 Hello, Anyone got any ideas how to separate the brake disc from the hub ( 300 tdi ) ? I have the hub and disc removed and also removed the 14mm splined bolts ( 5 ) but the hub and disc will not split. I understand the rust, grime etc will be holding it together but just how much force is required to separate them ? Many Thanx. Quote Link to comment Share on other sites More sharing options...
andyb Posted October 13, 2008 Share Posted October 13, 2008 I have to say that I have always used a press for removal and replacing. When removing once the disc has started to move (couple of mm) they then usually fall off. No reason why you couldn't use blocks of wood in appropriate places and a hammer to remove. Then clean up hub and use the bolts to pull the new disc on. Personally I never liked that idea for replacement and have only used the bolts as a guide when pressing on a new disc. Word of warning for either method. Rest the hub in it's centre only and not the wheel studs or you could push one of the studs back thru the hub, they are only a splined press fit.

michael100 Posted October 13, 2008 Author Share Posted October 13, 2008 Cheers Andy for the fast reply, I just sprayed the joint with our friend WD40 and had a coffee and then used a little more force then before and voila, they separated easily enough. I am quite heavy handed at times and thought at first I was maybe bashing the hell out it but on second thoughts, maybe I was too " lenient " with it but it is all back together and working fine, thanx again Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted October 13, 2008 Share Posted October 13, 2008 As you may have found out, it is easy enough to separate them so long as the disks are to be replaced. As that's the normal reason for splitting them anyway, a bit of damage to the disk doesn't matter at all. Quote Link to comment Share on other sites More sharing options...
michael100 Posted October 13, 2008 Author Share Posted October 13, 2008 Hi Jim, Yeah you are absolutely correct, if I was trying to keep the brake discs then I would have problems,.........i smashed 3/4 of the actual braking disc in the process of trying to separate the disc / hub ! Like you said though, there would be no other reason to split them other than to renew, thanx again. p.s. The Haynes Manual makes the disc change daunting, just like every other problem that I encounter, I prefer to come here and see how its really done, cheers all !

fatbloke Posted October 13, 2008 Share Posted October 13, 2008 I'm sure you have, but make sure you clean the mating surfaces of the disc and hub on reassembly. A little copaslip on the hub does wonders if you have to change them again. Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted October 13, 2008 Share Posted October 13, 2008 Michael, when I started there was nothing better than the Haynes manual, as the RAVEs were not really available. They are better than a poke in the eye with a sharp stick, but LR4X4 is much better. Anything you want to do, look in the Tech Archive and you should find it. If not, just ask. We do consider ourselves the best LR Technical forum with reason Quote Link to comment Share on other sites More sharing options...
clemo2k1 Posted October 13, 2008 Share Posted October 13, 2008 i just put the hub flange on a block of wood with the disk facing down and gave the disc a couple of taps (LOL) with a hammer and mine fell off i had mew discs to go on so hitting with a hammer didnt cause probs hope this helps Quote Link to comment Share on other sites More sharing options...
JimAttrill Posted October 14, 2008 Share Posted October 14, 2008 Ah, that is known as a 'technical tap' in the trade Quote Link to comment Share on other sites More sharing options...
