Just a quick note, pretty miffed but not suprised, when I replaced the front calipers I decided to try Paddock's non genuine calipers mainly due to other costs I was footing for the truck at the time, the caliper is 5 months old and at least one of the pistons is leaking, its going to be sent back and replaced with a genuine unit.
Lesson: If you can afford it at the time get genuine calipers, saves the ball ache of changing it out 6 months later.
I know there is the inevitable argument of don't compromise on safety. Which I belive I haven't, my initial justification of getting these calipers was on the basis that if it wasn't safe it wouldn't be on the market being sold from a reputable LR parts distributer... Now I'm starting to question that, working in an industry where engineering quality is paramount, it hacks me off that there is guff like this out there and people are happy selling it.
