brake drum removal - Land Rovers Only

bamarover · 03-15-2006, 05:58 PM

There are 3 large flat head slotted screws holding the brake drum on ouR IIA. Any tips on getting them loose? Large screwdriver got one fairly easily. The other 2 aren't budging.

Someone already rolled one a bit, probably last time brakes were done. I have put penetrating oil on. Would heating help or hurt? Never used a screw extractor and it is only 1/2" long Tips would be greatly appreciated!

Have you tried hitting the screwdriver with a hammer as you turn (kind of creates an impact wrench). Doubt that the oil would do much as it will most likely just run down behind the drum as apposed to getting through to the threads (but never hurts). Be carefull if you do use heat, the rubbers in the cylinders could melt (but would require a lot of heat to transfer to the cylinders), or you could warp something.
When you do get the screws out (usually they do come, you just have to fight with them, and you can always use a bigger hammer, you are not going to bust them) rememeber that there is a tapped hole in the drum to wind a bolt into to pop the drum off the hub. Can't remeber the size and thread off hand (and it varied with year and brake drum), but it makes it a lot easier to the drum off if it is stuck. As well get yourself some never-sieze and use it on the bolts before you put them back in. Save yourself this hassle again. Good luck, let me know how you make out..

I have hit it some with hammer and screwdriver trying to shock it loose, but had not tried to turn it at the same time. I am going to get the largest scredriver that will fit (mine is slightly smaller than the slot) and will try to hit and turn as you suggest - will have to get some coordination going.

Maybe if I just keep at it with the larger screwdeiver and hammer, it will give in. I will use the anti-seize, for sure. I guess 36 years in service gives it the right to be ornery about it. Thanks for the tip! Any other ideas that have worked, please post.

Another really good tool I picked up was an impact driver. I think I got it at Harbor Freight for about $9...comes with some different screw adapters, both slotted and phillips. It's like using the method that is described here, but it'll do the turning for you when you whack the contraption with the hammer. Every time I've been faced with recalcitrant drum or disc screws, this will do the trick...go get one.

Also, make sure your adjusters are backed off all the way before attempting to remove the drum.

Got a larger screwdriver and still not loose, but all that beating has to be doing something positive to the stubborn things. I have an impact, but all my attachments are chisel sized. Wiil go to Harbor Freight tomorrow and get the size needed and try to impact them off. We will get 'em off and anti-seize 'em so this will not happen again. Funny thing, the first one I touched came off fairly easily. Luck ran out, I guess! Thanks pickuprover and Bogatyr for the info and the quick replies!

I get an old screw driver and bray holy hell out of it the I use the screwdriver as a drift,put the end of the driver on the end of the slot and hit it with a hammer in the right direction of rotation to loosen it as of yet it has never failed me

One of those $9 impact drivers should be an integral part of your Land Rover toolbox, because they work really well for those stubborn brake screws. Just make sure you are wearing gloves while hammering cuz the spring loading impact torque can be rather hard on the skin of your palms.

Well, HF had plenty of impact drivers, but none with the screwdriver attachments. I'll keep watching for that! I decided to try the onslow method. Sure enough with a good ol southern beating with a 3 lb hammer and my screwdriver drift that happened to be slant tipped anyway to help a littlet more to get to the outside edge of the screw, they turned. Now, it has never failed me! Funny, 3 of the 11 I had left turned out with just normal effort of the screwdriver. The other 8 I beat up good. Wil have to get some new ones. Guess the penetrating oil and 36 hours helped some.
The drume were stubborn as pickuprover predicted. I never found the right bolt from my stock for the hole to push them off. I will figure it out and post later. A rubber hammer got them off this time. Thanks again for the tips! Now to the axle dismantle.

Time to break out the flame spanner
get it hot- smack the living bollocks off it and then try it with an impact driver
