The problem with pads is that by the time they need changing, the calipers have rotted away. Seriously - I changed my own pads on the 2016 one I used to have, and the piston skirts had crumbled, and the calipers seized up 100 miles later. Very pricey fix.For new brake pads I was advised on this forum a few years ago to try Halfords, and sure enough they did a very good job for about £100 l, and guess what, it came with a lifetime guarantee which I have not had to call upon because the brake pads are still fine, and will be replaced free once needed.
