Thread: Rear Discs conversion worth it?

I don't have all the details but was speaking to Merv Vessey of the LROC last Saturday and he converted his.

I thought one needed a full Defender rear end swap but Merv said one uses front hubs/stub axles from County/Defender and the conversion can be done using the County axle housing.

depending on how you drive and how you look after them usually a disc will last 2 sets of pads prior to requiring replacement.

The guy asking if they are Salisbury axles must be blind..


BTW,
Anybody who gets out of my '85 Isuzu (drum rear) & into my Chev tray with disc conversion will never say only a moderate difference in braking.
The vehicle weights would not be too different, but if you plant on the disc converted brakes they will lock up at 60 + kph.
I believe because it also has a 130 booster & master cyl..

Ah yes. It pays to clarify so, no- I am not blind just seeking more information. Perhaps you are having difficulty with reading skills? Possibly a lifelong problem? Maybe your eyesight is better than mine- if so, can you explain the various leads and pipes leading from the rear axle housing in the images supplied? Is the rear plate painted white and oxidised or is it alloy? Maybe it is a Holden Salisbury? Maybe the rig is good buy and is 'what it is' and 'fit for purpose'- Maybe not? Maybe it's a 'home job' from constructed from various parts sitting on a dirt floor? Perhaps the odd Chev component left over from previous attempts at 'performance'? Let me know when you have actually owned a 6x6 perentie and then maybe, speak with a little more authority.

In addition, with regard to the statement directly above, it is not generally considered a good thing for brakes to lock up- at 60km/h or otherwise. If this is the proof that you offer regarding a quality outcome from your disc brake conversion in your 'Chev Tray' whatever the hell dogs-breakfast that is, then perhaps judgement is also lacking.

I hear that an HJ 45 makes a good Chev mule. This is (by the way) an L/R 110 Isuzu diesel forum. Not many (none?) of these cars came out with disc brake rear ends so interest in this is perhaps understandable.

Hope this feedback helps.
Cheers mate...

either that or he cant setup brakes properly?

Hi Svengali0,
The rearmost diff pumpkin painted white is a convoy visibility thing the army does or did.
If you are thinking of using the whole axle/diff assemblies for your 110, then those off the 6x6 will be too wide. Perentie 6x6s have a wider track than their 4x4 stablemates. Though I'm only an internet warrior so don't take my word for gospel.

My 86 County has four wheel disc brakes and is a brilliant stopper. The previous owner fitted them. He said he used a "Factory conversion Kit".

Right OK here goes

There has been mini bun fights over this before and I suppose there will be again.

There is very little difference between a well sorted drum rear and disks, if any.
I can and do chirp the inside rear under heavy braking. My Isuzu is always loaded.

I elected to stay with drums and prefer drums for the following reasons.

I live in SA, so mud water or any thing wet is not a major issue.
It’s cheaper
In dusty conditions drums will out last disks. NO DEBATE.

Drums do require a bit more knowledge to set up well. i.e. there are different Dia shoes as your drum wears. Some after market shoes don’t have a chamfer (need to do this yourself)
They need manual adjustment ( No big deal, if every thing else is good 30 seconds for both)
Cleaning is not a bad idea, (every time you pull a wheel off)

But the biggest advantage is I know I will always have rear brakes to get home on and will not be grinding steel on steel or have ½ a rotor rip the caliper off ( seen that a couple of times)

I have seen rear disks cut out in about 15000K although that is extreme.

If you were to go out an get a new set of drums & shoes. It’s a lot cheaper than doing the conversion.

Now if you were a puddle jumper or just wanted bragging ego stuff then by all means change to disks.

Svengali - no need to get offended... They are undoubtedly salisbury 8HA axles - check the diff ID pics I posted in the 6x6 thread. A blind monkey can tell they are far too large to be holden salisbury.

The diff pan is clearly the standard steel pan, painted convoy white with some rust. There appears to be a breather coming out of the diff pan. The rest of the hoses appear to be brake lines.

There were definitely disc-braked 6x6 and 4x4s - as least the RSFV vehicles. I posted a pic of a 6x6 disc hub I bought earlier in this thread - the guy I bought it from bought it from an army auction in a job lot - unfortunately most of the others were drum hubs.

Svengali,
I should have guessed a forum member might have queried that Ebay ad. I plain forgot that the perentie were drum setup, my bad.
With 20 posts, may I welcome you to the forum.
Here is the link to my Chev powered Landie, it is the opposite to my Isuzu, but I love them both for different reasons.
If you read the thread- it's a challange, you will see that the vehicle was largely as setup by one of Melbournes most popular Land Rover mechanics, Fred Smith. And, as stated the all disc setup, IMHO, pulls up the vehicle much more smartly than the Isuzu - I'm repeating myself tho.
As far as the Ebay ad goes, the guy says it's ex Perentie, so I thought you were asking the bleeding obvious ( I still do)
