Hi all, this one is hopefully fairly easy. Essentially I have a vehicle which to my mind, went quite under utilised for the last year (covid and all) yet when I took it for a service, there was what appeared a steep decline in its brake conditions.
Make Hyundai
Model I30
Year 2018
Mileage 16,021 (12,736 on service 14 months prior)
So for some backround
Essentially, on my most recent service (start of this year) it was flagged the front discs were 95% worn, at 23.5mm. This was clarified as meaning worn towards their recommendation of 23.4mm as a minimum. Under their rating system, this was flagged Red. For wider context, Front pads are 40% worn, rear discs 20% worn, rear pads they ommited to give a number, as they instead recommended a service to fix binding).
the service before this (14 months) had everything green, including the front discs which were 95% worn this time round. It transpires the difference between the two was 2mm for about 3.3k miles. Not sure how good or bad that is, or why the margin between green and red is so slim..
The actual question at hand
Can someone educate me in terms of legality on the brake disc wear, but also the safety aspect here. I'm not simply trying to be cheap here, but they did want to charge about £350 quid to replace them, and in my mind it had barely any mileage. 16k over 3 years isn't a lot. I got it at about 8 months after its registration, so to my expectation, everything is factory fitted. Being told the brake discs are basically done when the pads are only at 40% wear makes no sense to me. Hyundai aren't being particularly helpful either, when I ask them if this is expected wear, and what the sizing in mm is out of the factory, they pointedly ignore the question. I get the impression their email is being handled by one individual as well, hence its maybe not their fault about the poor response I'm getting. I don't know what's going on with their staffing right now.
I got Hyundai because it seemed a decent brand, with a good reputation. But I'm not impressed at the idea brake discs need replaced every 16k miles. Perhaps this is the reality now with metal discs, My previously car was a 2004 Vauxhall Astra which I had for about 8 years. I replaced the pads about 3 times, and the discs never. I see a lot of people mention the removal of asbestos has reduce the lifespan, I'm not sure if a 2004 Astra would have had that.(incidentally I got an i30 for comfort, its not the case I'm accelerating and braking hard here.)
From someone that isn't after a quick service fee:
Is the amount of wear here actually a problem?
Are there legal limits I should also be aware of?
How soon should these be replaced?
Is this an expected level of wear for a modern car?
Bonus points if someone can tell me what the stock width of these ought to be, I haven't had any luck getting that info
I haven't had cause to use it much recently, but I will make a few long trips in the coming months as lockdown eases, and if this is in fact a tangible risk I'll have to bite the bullet and replace them.
Any guidance for a noob is appreciated. Cheers.
