Ordered some Clark's brakes for my sons mountain bike. Before I fitted them I decided to remove the pads to see what type they are. The screw pin with the hex head was that tight that the hex head rounded. I tried the pin on the other calliper but didn't use as much force as this would've rounded off too. I thought I would leave that one so that they could see for themselves that it was not right. Well after emailing photos and warranty form to them they just came back with "you must have used the wrong size hex key so warranty is void" I can assure you that as a service engineer for 30 plus years I definitely know my way around a set of allen keys. And incidentally my Allen keys are snap on and not the pound shop multi tool that they gave me when I bought my wife's £500 qube bike 3 weeks ago. I've not even had a reply to my last email so I've ended up here leaving this review. It's not the only place I'll be leaving feedback. All this for some £60 brakes.
