Disco II Brakes!

Rev · 24th March 2006, 10:03 PM

Gents,

I haven't posted here before, so please forgive me if this topic has been raised already.

I've got a 2001 Series II Discovery TD5 Auto Seven Seat from new.

My first set of brake pads lasted to ~73,000kms.

Second set only lasted to ~112,000kms at which time I had the rear discs replaced too.

Third set got me to ~155,000kms when they replaced the front discs.

Fourth set got me to ~202,000kms when they had to replace front and rear discs.

Now I haven't changed my driving style to that extent to have after the first set of brake pads, the rest lasting about half that of the first, but the real clincher was the fronts discs where the first set lasted 155,000kms and the second set lasted 47,000kms.

I guess I'm trusting the dealer on this one, they are very reliable and have always served me very well and I really have no cause to question them, but does this brake wear seem odd after the manufactured fitted items were replaced?

The dealer assures me they only use original parts.

So, have Land Rover changed disc and or pad compounds to such a degree as to reflect this extra wear.

TRev.

Hey thanks Ray.

Did I see your missus down the street (Berwick) a few weeks back in the 130?

Don't tell me the 130's been assigned domestic duties as a shopping trolley?

(I seem to remember it had a decal on the door with a red circle, I'm sure I've seen a pic's of your's that show that sort of decal, if not I got the wrong vehicle and I'm dreamin')

<span style="color:blue">i would say the first set should last the longest....

you are running in a new engine...and taking it easy on the vehicle.....
the discs are new....
the pads are new....
suspension is nice and tight....
every thing is rosy......

as things start to wear and you get more confidence in your new car....
you will start to push it a bit harder.....
as it loosens up it will roll easier...hence needing more braking to pull it up...
new pads on new discs will last longer than new pads on used discs...

and yes...they can change the composition of the pad material.....
one such change is the elimination of asbestos.....years ago....

you seem to be averaging 40,000kms per set....
sounds fair enough....1 set every two years on average......
replacing the rotors im not too sure about......they should be able to be machined
once or twice before they are unserviceable......
unless of course they are badly scored from the worn pads not being replaced
promptly and allowed to go metal to metal.....this may deem the rotors unusable.....

brake pads should be changed when the friction material is less than the thickness
of the backing metal.....
on a routine service....if the pads are low (or close) they should be replaced
as they may not last till the next service....it is up to the mechanics discretion
as he is the one who does the work and gets to see the wear....
if he thinks they wont last he will replace them.....
its better to replace earlier than to get your car back after a service only to find out 2 months
later your pads are worn out....

what we used to do to cover our backsides was to write a report on the pads....
ie...front pads only 7-10,000kms left.....saves the customer money while letting them
know that their pads are low.....they should drop in again after about 5or6
thousand kms to have their brakes checked....

also note that the thinner the pads the sooner you will experience brake fade....

i hope this helps a bit.....</span>

I am on my 3rd set of rotors at 155k's in the process of fitting EBC rotor's and pads to see if they last longer,I have a heavy right foot plus a few mod's, tend to make it work when off road as well.

Some cars the rotors are throw away as there is no margin for machining the rotor's.

Does anyone use non-gen. rotors &/or pads? If so which brands & what are they like as far as performance vs price? cheers

**Pedro_The_Swift** · 27th March 2006, 05:13 PM

this info from a repco inspection I had done last week in Melb,,

fronts 23.7mm-- fronts to be scrapped at 22 mm,
rears 12.4mm-- rears to be scrapped at 11.7 mm,

material remaining in pads at 84000kays-
70% front and back.

so 155K looks alright for a first set,,

edit;1
DBA standard replacements start at 25mm.

At 100,000 kays, I replaced both rotors and pads all 'round for the same money the dealer wanted to do the rear only. The rotors were beyond machining limits.

I used DBA rotors and Bendix pads. At 160,000 kays, the rotors have hardly worn at all and there is a lot less brake dust on the wheels.

Forget the genuine bits. Use specialist brake manufacturers jobbies and get better performance for a lot less money.

Im also a newbie...hopefully picking up my td5 dico tomorrow 8) ...woohooo!
An independent L/R mech that inspected it said the rotors need replacing(as well as a few other things :roll: ) but has anyone got access to what the specs are ..i know that
