Defender 90 Drum Brake- theories please!

So i put the defender in for a service a week or so ago and as per my "introduce yourself thread" the main thing they found wrong was one of the snail cams in the real drum brake was broken and needed replaced. So finally got the part number and ordered the part...result!! Took the landy down to the garage to have the new cams fitted today and get some other bits tweaked only to be told by my guy that its the wrong part!! There is only one type of snail cam for landrover drum brakes as confirmed by landrover but the broken one on mine is about 5-7mm larger circumferance a different metal and slightly thinner!!

So!! could this have been a military bodge? to allow the current shoes to fit? or am i missing something....

Theories please guys.......

Being ex-military, has it got a Sailsbury rear axle fitted?

mmmmmm ok.... no idea .... how do i find out?

Google image search...

Does it look like this http://www.rovertracks.com/images/products/salisburyaxle275.jpg

i.e. is the the diff pan is pear shaped?

Ok look at the bacl of the landrover can you see bolts holding the diff pan on if not look from the front can you see nuts looking from the front of the landy backwards. Jai

are the bolts around the diff banjo facing the propshaft side or facing the back of the vehicle

Hi, no nuts at the back only the drain plug. All nuts at the front looking back. So not like the photo as the pic looks like i can see nuts at the back.
cheers for this..

post a pic of your old cam, also of the shoe and spring arrangement

Its a rover diff then. Post a pic of the cam it mabe be a LWB back plates 11 inch instead of 10 inch standard brakes Jai

they both have the same snail cam fitted, it's just the shoes, expanders and backplate etc that are different between sizes

Hi, hopefully the pics are attached

cheers

its also a 10 inch drum

Hi Sean,
Parts came from craddock p/n RTC3176 which was a complete set for 4 drums.
cheers

OK... the story gets worse it seems... phoned PA Blanchards and sent them the above pictures. They have never seen cams that big and have no ideas why they are on my landy or how to rectify the problem of the new cams not fitting.....:doh:

If the back plate is genuine then everything else should fit. If it doesn't fit then you need to source a pair of drums and backplates etc off another 90

they could possibly be from an old bedford truck adapted to fit by the army might be worth asking a mil specalist Jai

90's don't have 4 drums??? they have discs up front Have they sent you series brake parts?? and are they different to 90 drums??

edit..

Just looked in the Manual and they don't even have snail cams to adjust. just springs. what year is your 90?

Hi its a 1991, drums on the rear and discs on the front. The military were a bit slow putting discs all round and used series drums on the first defenders they had. The cams are the same part for all. Made more phone calls and no one has seen these size cams so looks like i need to replace the backing plates and everything else at the mo .... expensive job !!

I have an 87 90td with rear drums front disc brakes as well. Don't remember then having cams but I'm sure they must have had em. or they wouldn't self adjust?? Might be easier to just get a complete axle off ebay.
