I bought some pads for the front of my v70 t5 and asked the local garage to fit them.
They said the wrong sized discs were on the car in the first place, so they had to fit new discs and subsequently new pads also. Apparently the ones I bought were not the right size.

Anyway, a couple of months later and I've been getting brake squeal, really annoying so decided to add some copper grease to the rear of the pad.
Took the wheel off and noticed there were no brake pad retaining springs on the calipers.
Carried on and fixed the brake squeal, then called the garage and asked what had happened to my springs which I was sure were on before they did the work.
They asked me to go show them, so I did, they then said new springs were on the way, then said new springs wouldn't fit and weren't needed anyway.
They said that if they're were no springs when I took it in then they wouldn't have needed them or some ****e like that.
Then said maybe the calipers fitted weren't standard perhaps and so on and on....

Anyone know if I should have these retaining springs fitted or not and if they serve a purpose?
maybe I bought a v70 t5 which has some other calipers fitted but don't know what they are.
