Hey, How do you know when your brake discs need replaced? Is there any indicator anywhere? Or do you measure thickness etc?
sometimes there's an indented spot which wears away, sometimes on grooved discs, the grooves themselves is the indicator (e.g. Brembo Max discs), sometimes you need to measure, so no simple answer..
Think there and indent on the edge of the disc, soneone on here recently fitted new discs abd spotted it.
Reason being because they've not been in the same place or the same size indent on the discs i've had.
yeah, that shave looks way too large to be a wear indicator.. also, the min/max thickness difference for a disc is usually around 2-3 mm.. that looks to be way more than that...
I wouldn't worry too much, I had a customer return a set of discs (after kicking off on the phone) because his discs had big cuts in them..... Turns out it was the machining for the balancing.
