Disc Pad Replacement on Disco 3

[hopperoo]

Not sure if this is the right place for this but here goes anyway.

It was mentioned to me today (by the service manager) that with the Disco 3's when the disc pads need replacing the rotors will need to be replaced at the same time (on average at around 30 - 40,000kms)! The cost quoted at the dealer was approx $800 for fronts and $600 for the rears (pads and rotors). He did say that normally the fronts are replaced twice as often as the rears.

Anyone had any experience with this. My experience with Pajeros is that very rearly are the rotors replaced until they've been lathed several times (after several pad changes) at about 200,000 +kms.

Two questions; does this sound the "norm"?
; If so is it recommended that you use OE parts or are there after market replacements that are much less expensive BUT will do the same job?

I dont have a disco but that sounds like a load of cr@p
If you are told they need replacing have a look at them and ask why.
even if that was the case go DBA instead of LR and save $$ they are just as good IMHO maybe go the cross drilled & slotted to for a bit extra Stop.

From the DBA page,
http://www.dba.com.au/2006/PDF_CATAL...Catalogue_AUST

It lists Discovery 3 minimum disc thickness, 27mm front, 17mm rear. You've got to lose 3mm from original thickness to get there.

I think someone is telling you a porkie, but a measure will tell.

we recently had the same issue with the work disco - it gets a hard life but the fleet mgt company wouldnt let it go to LR to get the brakes - so it had to go to Ultratune.... no problems yet - even though LR said it would never be the same.... but if ultratune used bendix or dba parts should be ok IMO.

In the old days that was the case. Now days generally if you get two pad changes to a set of discs you've done well.

I think the move to asbestos free pads meant a change in the disc and pad materials. They don't last like they used to

MMM yes well changed my pads all round at 35k and recon by 60k it's going to need discs...it's 2.7t so it makes sence...it's a lota car!

could try getting an agressive tye disc/rotor, (you know lots of slots n holes) and really soft pads.
That way you replace more pads but stop faster and you discs last longer.

I tried this in my (wash my mouth out) Falcon and it worked well. Second set of pads on new rotors and they hardly look worn.

[cafaas]

Sounds like a real ripoff price to me.
Not sure I'd be changing rotors without getting good reasons also.
LR will just go by their schedule whatever it says.
Possible reasons to change - Rotors getting too thin - then measurement should tell you - or a pulsating brake pedal may mean they are warped - usually when they get too thin and/or heat up quicker under loaded or heavy braking. Can't see many other good reasons.


Disco 1 V8i - 225,000 km - rotors never changed or machined. Smooth as silk and still lots of good steel. Have used asbestos free composite pads, as well as steel pads over the years without issues. Steel pads last longer but don't brake as well and are noisier (squeakier), but are super-dooper for going through lots of water as they don't soften up and end up wearing quickly like the composites.

Done 95000km

Had front and rear pads replaced twice.

Disks machined once.

Yup. As Jamo said, these things are hard on pads and consequently rotors. The rotors are designed to be sacrificial, this aids in high speed stopping, and helps in heat disapation also. Pads and rotors at the same time on these 2.3ton auto trans equipped vehicles isn't out of the ordinary.
