Wear limit of Clio 172 Discs?

[griff999]

Hi,
Does anyone know what the wear limit is on the discs for the Clio 172 Ph2?
I cant seem to find this info anywhere.
Cheers,
Griff

There should be an indent on the top of the disc. When it gets to that i believe. Its a good 5mm from now i recon

Ah, OK thanks, Ill take a look.
I thought I'd been clever (or lazy) by measuring them with a micrometer without having to take the wheels off!

21.4mm IIRC 24mm new something like that, rear are 8mm new 7mm min

i've always changed the discs as a change the pads on my cars tbh... just seemed like the right thing to do

That sounds right Fred. A garage told me the fronts were getting worn, but I think they seem fairly new - they are over 23.5 mm and there isnt much of a lip at the edge. I think the fronts are ok then.

The backs do seem v worn though, one is under 7mm so Id better replace the discs and pads I reckon.
Thanks for your help.

I presume thats the distance over the vented section on fronts?

Almost right fred, the book says 21.8mm for fronts. Im changing mine at the weekend.
