Hi all. Have just found out the the inside rear pad on the driver's side is down to the metal. The car has only done 70,000 km. Have dropped it into the service centre to have pads and rotors replaced but I'm not convinced this is normal wear even though they are adamant it is.

Has anyone else had similar experiences or should I be pushing for further investigations?

I have over 160,000km on mine and have replaced the front pads once and never the rears. If it's an ex-rental the ESP may have used all the rear pads up?
 
Seems to be the new thing to replace pads AND rotors at the same time, rather than skimming rotors. Lot of trust in such advice, but who are we to question that, or feed suspicion!! at least we are keeping someone employed in these difficult times.

Rotors only need replacing when they reach their mandated minimum thickness, not before. Scored rotors have more contact area! :)
 
Hi Jolly,
Suspect caliper pins are either corroded or other such issue leading to one side of the caliper contacting a pad and not the other.
Replacing pads without finding out the cause will just replicate the issue again.

Clamp brake line, remove caliper, rebuild/service, replace caliper, bleed caliper.

Yes I would investigate why the pads have worn unevenly, the wear on the pads should be fairly even.

Also you would most likely go through 2 sets of front to one set of rears.

This is what gets me. I've never known a car to go through rear pads before the fronts.... let alone at 70,000km. I'm not going to let them tell me it's normal wear and tear. It's still under warranty so they can resolve the issue.

My understanding from your first post it is just one pad that has worn down to the metal and the other three pads are ok, is this correct?

If so this is not normal and there is a problem that needs addressing.

Normal wear is where all four pads wear pretty much equal on that axle, whether is is front or rear.

Yes that is correct. I've contacted them this morning and asked that they put the pads and rotors aside so that I can get them and inspect them when I pick up the car.

Definitely something is not right. Both customer service people I've spoken to have told me that this is acceptable for a Renault.

Its not acceptable for any brand of car.

I would love to know what training these so called customer service people have had, must of majored in spin.
 
Muppets.....
Had a door knocker yesterday pre selling servicing deals to the neighbourhood, they were a large brand tyre sales store. I told him our Euro needs to go to guys who know these vehicles pointing to Carlo5.

Oh we service Euro cars....then I mentioned last time we went to this store they couldn't even balance the new tyres they sold me!!

Muppets that just take your cash with no comprehension. Probably same Muppets that don't need to use low saps oil as they know better than the customers.

Jolly make sure they sort and supply a repair breakdown

Well seems like I've hit a brickwall. Have spoken to the salesman, the service centre, the centre where previous services were done (front pads and rotors done at 40,000km in 2019) and even Renault Customer Service. They are happy for me to get a second opinion, just as long as it's from another Renault service centre - the closest being 2 1/2 hours away.

As far as they are concerned, if a Renault mechanic says its fair wear and tear, then it's fair wear and tear.

Thanks everyone for your input, but I don't think there is anything else to do but accept it. I'll just have to keep an eye on that corner, and see if it again has uneven wear - they then might consider it to be an issue.

Can't be fair wear and tear, how can one side wear faster than the other?
If that's the case the manufacturer would have only put in 1 pad.
Take it to a brake place and ask for a inspection/caliper rebuild.
The cost is sometimes better than loosing your sanity talking to morons.

Is the car still under warranty?

Yes. Still under warranty.

I would be taking this up with Renault themselves, let them know how dis-satisfied you are with the outcome to this problem as as far as you as concerned the issue is not fixed and you will be doing this again in 70,000 Km. You never know you may get some action.
 
I have already spoken with Renault. Their response was to get a second opinion - but it has to be from a Renault service centre.

If you had been servicing your car at a non-Renault dealer (and in so doing legally keeping your warranty intact under Australian consumer law) Renault would still have to pay to fix the problem. If you have your car inspected by a brake specialist for a report why would Renault not accept their findings? Also, unless you take the trouble to put your own markings (by metal stamp or etching) onto your brake parts I know from experience that all a dealer has to do is pull some parts out of their rubbish bin and tell you that they are yours!
 
70K kms out brakes pads is very good going these days. My Megane 2 was halfway through its second set by then.

And most modern cars will wear front and rears at a similar rate. The Alfa is almost looking like the rears going faster than the fronts, but the Meg certainly had all 4 done at once at around 50K kms.

Soft rotors help with high speed european autobahn stopping and give great cold bite - but they wear quickly.

Brakes are cheap (assuming youre not silly enough to let a dealer do it...).
