EBC Disks - Modified
Discussion
Hello all,
I bought some EBC brakes (Turbo Groove Brake Disc) but they are not drilled and i wanted to get drilled ones but as you all know they are very exspensive!
The one i have bought are part drilled but because of where i work i can get them fully drilled, is this a wise idea?
Or should i leave them to how they were made ?
They look like these !

Whilst I'm no expert in this field, I'd avoid serious DIY mods to critical things like brake discs.
There's no reason to expect they will perform any better post "surgery" but you'll be kicking yourself if it goes wrong on the workbench... and risking a serious injury if one lets go on the motorway for example.

Drilled disks are normally done before the metal is heat treated. If you drill after treatment they will likely fail. Anyway grouved and dimpled are better than drilled as they generally are stronger and still allow gas preasure release form the pads. Agreed there are better discs than EBC but they did fine for me.
I used to circuit race with cross drilled discs that were mandatory. A few of us experienced gradual cracking creeping north and south of the drill holes. Eventually I had one failure that went from one of the outer holes right to the outer edge of the disc. You could feed a piece of card through the gap. Stopping power was significantly reduced and it acted as a bacon slicer to my pads. Now of course, it could be that this particular brand of cross drilled discs were poor and not all cross drilled are bad BUT it was interesting to note that the manufacturer's revision to cure the problem was to create the next generation of these discs with only partially drilled holes(like the ones you have shown.) They worked just as well and no cracking.

Spot on, dont drill them, the reason they are dimpled and not drilled is to retain the strength. Drilling it will break the grain of the metal, weaking it substantially. I had drilled discs fitted to a car and they cracked from the drillings for a past time when they got hot, ridiculous.

Does this actually still happen? I suspect that pad material is miles better than it used to be so all the grooves, holes, signatures etc on discs are all just to make them look pretty.AdrianR
