New disc issue

In my garage I have a set of disks of HRH's mini.

The grove cut in the disk measures 8.4mm, the same as the minimum thickness stamped on the front of the disk.

I measured using a digital calliper, so I am MORE than happy that I'm correct in what I say.

It's not a wear indicator. Discs lip when they wear as the pads are always slightly inset from the edge of the disc so that the pads don't lip.

The balance machining will be the same width as the disc at max wear so that the minimum amount of material can be removed from the disc (i.e. No deep groove which would weaken the disc). If it was any wider than the max allowable wear there would be the risk of the disc balance changing as it wore.

So whats correct?
A forum post from 4 years ago or a youtube video from 6 years ago.

Not sure I understand the point of your question. :?

However I believe the video is, as it clearly shows how the marks are made. Plus there are other similar video's of brakes being balanced using this method, all over the internet. :wink:

Sorry my question was about whether VRsteve was correct with his idea that the marks were wear markings or Warmasices original thoughts on balancing which I agree with.
VRsteve, at what point do I get an apology either on here or via PM? :)

Was an apology offered by PM with the good grace that you publicly offered yours? :|

Its only a bit of banter but no it hasnt been offered. I was only throwing back the line about an apology as it seemed a bit smarmy of VRSteve to demand an apology from me after he assumed he was right and I was wrong after I laughed.
VRSteve obviously thinks that he is correct (he might be although his only defence is another forums post which could also be wrong and that the measurement of the cutouts match the minimum thickness which could be a coincidence) even though it seems most on here think its for balancing.
As Attilio also says, maybe it is for both in which case I was wrong for laughing but also correct.
An apology is not needed. :)
 
Fair enough. I was curious because you offered a metaphorical handshake and seemed to receive silence in return.
Besides, the cut outs are clearly a cost saving measure by the manufacturer - less metal, less money :P

Mine are full of holes too. Bloody tories!

:lol:
 
Here's a better video proving it's balancing.

I have to admit it's pretty darn obvious if you know anything about cars that the the thickness of material before you reach the groove pictured is way too much to wear down to. The disc would explode into pieces if you ran it that thin.

Generally, wear allowed is in the region of 1mm each side by which point there is a pronounced lip. So in some ways :lol: is not unfair. If you don't know don't be so strong in being right and you won't get derided for a mistake. :thumbsup:

It's for balancing the disc. No shame in making at guess at a wear indicator but that just isn't correct, and looking at Beedub's link above I'm not even sure why you continue to question it.
 
The Easter Duracell Bunny was hungry and ate bits of your discs. Don't worry though he's a very well balanced bunny and never wears out. :D

(Yes I 'm bored)

Not aimed at you bud
Just it's meant to be a forum for people to help each other and give advice the best they can
We aren't all experts it's a forum if want it specialist
Pay a garage
I can't stand the catty behaviour hence not been on in months
As much happier living without it
