Thread: Discovery 4 TDV6 MY15

Hi

For your info I had my front brake pads and disks replaced last year. The disks were a bit scored but did not have the thickness needed for machining.

2 Brake disks $250
Brake pads $200
Labour $190

Hi DVV,
Despite your low mileage, I suspect your car has mostly been driven around the city? Or at least in peak hour to/from Ingleburn? If so, then the stop/start nature of peak hour driving and braking on the freeway from 110 is probably the most arduous conditions your brakes could face. Far more arduous than, say, spending its days in low range on mountain tracks.
Replacing front disks at under 50,000km is perfectly normal for a city D4; they are a wear item after all. The lip is perfectly normal. From memory, you're allowed up to 2mm wear. You'll probably need to replace the rear disks in another year or so. Personally, I'd do it at the same time.
If you intend keeping the car for a long time, may I suggest you replace the transfer case and diff oils within the next 10,000kms and start an engine oil and filter replacement regime of every 6 months or 12,000km whichever comes first.
The hydro bushes on the front lower control arms are also a sacrificial wear item. These give you the sensational ride and control, so replacing them every three or four years is a small price to pay. I've just replaced mine for the first time at 90,000kms but most of my driving is country roads plus a bit of serious work in the divide.
All of the above service items are not that difficult to do yourself, though I admit you need a bit of mechanical know-how and the right tools. Either that or find a decent Indy.

The car has never been off-road except for the training provided.

questions which are bothering me is how did the front discs get lipped and the bushes worn out by road driving at 47k...

I need advice on whether this is normal...and a car that is capable of off road .. has bushes stuffed at 47k ...

From my experience, City and urban driving can be pretty arduous, especially on the transmission too. As a preventative measure would be looking at a full flush and steel pan upgrade in the future too.

Lower control arms and their bushes are a known weak spot, the hydro (oil filled) bushes just aren’t up for the job of longevity, but as stated give great ride feel. Probably cheaper to replace the complete arm than mucking about with re bushing, at least that’s what most do.

re brakes, the oem rotors are very soft (relatively) and wear out quite quick, the trade off being great braking power for a vehicle weighing close to 3tonne. Easy enough to replace yourself (if so inclined), there are some great options available. I’ve just done my second set of brake rotors and pads in 191000km, and now on RDA slotted rotorsRDA Brakes, The Big Brakes Company. | Products - Rotors and TRW pads. Home

Much better than oem IMHO (diy install).

saw the “cracked engine cover” note- that’s a new one.

Get them to check the clearance to the top radiator hose, as the cover rubs on it and has been known to cut through, leaving you with no coolant.

also, front and rear sway bar bushes get harsh, I’m about to do the second set of those as well.

Well for what it is worth my 07 RRS has covered 175,000km and it is still on its original suspension bushes - they do make a little noise but are not clunkers but will need attention soon. Original front disks were replaced at 150,000km and still had 1mm wear to go. Rears are still the original OEM disks and still within wear limits.

Why 12000 and not 10000 or 15000? We’ve just bought ours and I’m also looking at changing the service schedule to something more sensible.

At 12k everything is still well within spec, it’s a good intermediate step between the original 24k. Therefore maintaining the easy to follow main service schedule.

My 16.5 D4 has factory service at 26K. This also appears in the service manual although its a bit vague. 24K is for older D4s. Not sure when they changed the distance. My Indi put the service at 13K which I do by just changing filter and oil.

Yep, std factory interval is 24k kms for older D4s but the general consensus is thats too long. Most on here run 6months /10000km for std oil services
