No, you are out a set of rotors because you didn't check your work. You claim to be an Audi tech?
After your libelous post, who knows?
Victim! The victim!!! You bought a ****ty rebuilt aftermarket part and tried to mate it with another aftermarket part from a different manufacturer, didn't check your work, and now you're the victim.
Yes. When you buy the equivalent of Auto Zone-brand parts from a company who also sells Ford F150 fan belts, yes, you need to question every part you get from them.
Poor customer service? Because they didn't bend over backwards and overnight you a new El Cheapo caliper? LOL.
Time to pull out the Big Boy credit card, throw down $140 for some ****ty Britpart caliper at AB and have it overnighted. Own up to your ****-up and quit being the victim.
So, you jump down the throat of a guy who was possibly sold defective parts, preach all high and mighty, and then show your complete lack of knowledge on parts quality by advising a purchase of Britpart callipers. Britpart brake components are notoriously shoddy. A quick search of any UK LR forum, where there is a huge wealth of experience in these things, will tell you not to use Britpart for mechanical parts, especially safety critical ones. Britpart is a wholesaler, not a manufacturer, and while some of their stuff is fine, and some of it OEM or even better, such as their CV joints, much of it is unbranded, ill-fitting crap from third world countries fit only for re-smelting.
He may have made a mistake on failing to check the clearance of the parts, but it would appear that someone has provided faulty or mislabled parts. Whether it's an undersized calliper or oversized disc I couldn't say, but a decent vendor will try to ensure their parts are correct and of suitable quality - your contract is with the vendor, not the manufacturer.
I can't say that I'm impressed by the bullying mob on here, either. Some of you have acted like school kids.
Ultimately, it's a salutory lesson in not buying cheap or pattern parts, especially for something as important as this. I'd recommend fitting genuine Lockheed callipers, which aren't expensive if you buy them from somewhere other than LR - the Gen Parts stuff is horrifically marked up.
