Brake disc handing


Registered User
Taking advantage of the ECP 50% off brakes I've got a full set of Brembo for another German car .

Both vented and fronts are cross drilled.

Now I read the internal vanes have to point back to correctly vent from the center to outer disc . If this is correct I have two pairs of left handed discs .

The n/s left front cross drilled go back and so do vents but on the o/s right cross drilled point forward and vanes forward.

Same situation on rear but rotors are plain .

But the discs currently on front do have the cross drilled going back on L and forward on R , can't see vanes though , is this the norm ?
