Acceptable disc wear?

[Oldmogman]

I've noticed that my brake discs have become grooved - the grooves aren't deep but they're visible. Is that acceptable?

They've done around 40,000 miles but I wouldn't think they're due for replacement just yet?

However, I've noticed replacement discs for the Marina set-up are vented ones, which look much thicker than 8mm solid ones fitted. Do these fit the standard calipers? Or can anyone suggest where I might get solid discs (if I need them at all!)

Thanks all

As long as there is still decent thickness on the discs - they will be fine.. I'm sure new discs will still be available - same discs are used on TR7.

I doubt you'll need new discs after 40,000 miles unless you did 1,000 of them with no pad material !!!!

That would at least wear them smooth...........

My Marina discs have done 60,000 plus miles and still have plenty of thickness left.
