It\'s by no means \'accurate\' but i\'ve always gone on these kinda figures. More importantly, the 3 figures on both front and rear rotor should be close to each other. a big drop on one side could indicate problerms (in bar below btw)

8+ bar perfect
7+ bar great, plenty of life left
6+ bar ok, some life left, be wary if new purchase
5+ bar be prepared for a rebuild and probably already has hot start problems
4+ bar fcuked.

mid 6s to 7s is fine for a good few miles in IMO, below mid 6s on all three faces is when the tips or housings are starting to wear out and lose power

that 7.3 on the first rotor is a bit out of line with the other two readings...

depends on how much the car is up for really...
