The brake problem (vibration) turned out to be a front rotor that was pitted in an area on the inside wearing surface, but only in a quarter of the surface, so when I ran my hand over it, I had missed that part of the rotor and was unaware of this pitting until I took the rotor completely off the vehicle. I have replaced the rotors with the same kind, only coated. I have just finished speaking with Raybestos Representative local to my area about issuing a refund for the replacement pair of rotors, which sounds promising, but I'll have to go through the dealer. I have also been assured that Raybestos rotors don't normally do this, that this is a one-off case. Although my confidence in Raybestos rotors had been shaken somewhat, I hope this is not going to happen again.

My trusted mechanic did the plugs for me, and am I glad I had him do that, took him an hour and three quarters to complete the job! This was the most expensive spark plug replacement job I have ever done! The OEM plugs were starting to look quite corroded and carboned up. One even had a longitudinal small hole through the ceramic allowing the combustion to flow through it! Hopefully the new Iridium IX spark plugs will hold up better.

I hope this helps those on this forum facing similar problems.

Cheers
