I would never drive my car with brake pads@ £30 quid. I simply couldn't trust them as I have always found that you only get what you pay for. Please keep us updated over long term on these pads to whether they break up like the brembo ones due to heat etc. Other members will value the feedback alot.
I have only had them on for about a month and so far so good. I do however have the same brand Mintex on my Toyota Land cruiser 4x4 and they are excellent. Long life, no brake dust (hardly) and about 2-3 years out of them (45,000 or so) and I live in Milton Keynes, where there is a roundabout every half mile so braking is very heavy!
