I have recently had Rossini drilled and grooved discs fitted to my 1975 S2 V8 since these were a straight replacement for the standard ones and claimed better stopping power.
The improvement has not been great and there is now a continuous intermittent whinning noise which seems to come from the rear, particularly noticeable since I usually drive with the window down!
The installer has checked this out and insists that nothing is wrong; the discs themselves also appear to be working OK with no vibration through the pedal to suggest they are warped or faulty.
Am wondering if the cause may be wind noise as air passes through the vent holes causing an intermittent sound as the discs turn. There is no difference when applying the brakes and the noise is only heard when moving.
I have also spoken to the supplier who is unable to suggest anything but has said that some users have reported noise problems with these type of discs.
Grateful for any views or similar experiences.........
