Why don't we rotate tyres but you rotate tires?

tl dr: Kwik Fit is full of crap. It's good to rotate tyres (and tires, too :o). The entire idea of rotating tires is to keep the wear relatively similar (or even), front to rear. If rotation is done ...

Is it normal for brand new brake rotors to look a little rusty

They're used - you can see the marks on the center where they've been attached to a wheel. They also look scored - run your fingernail across those scatches; if you can feel the ridges, it needs ...

Why don't we rotate tyres but you rotate tires?

You always fit the best tires on the rear. Why? They don't motor*, don't steer and barely brake - why can't rear wheels just be casters? The rear tires are your rudder They keep your car from ...

Can pulling up the handbrake without depressing the button wear or damage it?

Pulling the hand brake without pushing the button has no effect on the service life of the parking brake. The only thing that will wear is the ratcheting lock mechanism, and I doubt you could wear it ...

Why don't we rotate tyres but you rotate tires?

Check with the tyre manufacturer. If anyone would know, it'd be them - not a shop full of work experience kids. When rotating tyres, move the fronts to the back, and the backs to the front on the ...

What is more important the age or the mileage of a vehicle

Since you're asking specifically about a conversion van, and the mileage on both is relatively low, I'd say in this case age is going to be the most important. There are not enough miles on either ...

Brake pads finished on only 1 front wheel

I guess finished means completely outworn. This sounds like a seized caliper on that side, which always brakes a little and so wears the pads. It does not have to brake that much that you notice it,...

How can a damaged caliper prevent other calipers from fully pressurizing?

Your final thought is correct. Only 1 calliper was faulty. You said it that the pads on the faulty calliper had even wear, which indicates that the slider mechanism was not seized. The piston on ...

Rotating tires based on time or miles?

In a word: miles. Time has an effect on the tires, but it will deteriorate the rubber all the way around at a given rate. A tire is good for many years (some longer, some shorter). It's the effect of ...
