I know enough to be dangerous

Brake pedal vibrations are usually easily fixed by cracking all the wheel nuts and retightening them consistently.
That's an interesting fix

If it's been like that for ages and/or driven hard, then there may be a slight warp in the rotor.
This fault isn't warped discs. It only happens for 1/4 of a second after applying the brakes over 60km/h when applying a certain force to the peddle. The vibration is only felt through the peddle, not the braking. It looks like a common fault, although some cars it is very bad. I am thinking it could be anti locking mechanism (ABS), but in some cars it's worse than others. This may be normal.

Engine pinging is usually due to fuel that has a low octane running in an engine with higher compression.
These cars have modern EFI with knock sensors. I am no expert, but these engines should be able to handle a range of octane (we get very bad poor quality fuel in Australia), however, any one of the dozen EFI sensors can fail, leading to faults like pinging. Normally electronic faults are batch faults.

Hard to kill a Toyota though, so you probably can't go too far wrong.
They are the goods
Anyway, I've ended up letting my fingers do the walking. So, I am sorted.
Thanks for your replies everybody :)
