Hi, I'll have my disks and pads changed for the third time in 5 months tomorrow. Luckily they are under warranty but the garage (Kwik Fit) can't find a reason for them getting warped so quickly (only 3 weeks last time). I hear a rattle when breaking softly while at higher speed I get a strong vibration on the stirring wheel. It's on both wheels and the mechanic doesn't think it's either the hub or the caliper. Three consecutive faulty sets of disks/pads??? I don't want to waste money by going to a dealer and getting the job done there but I am also sick and tired of visiting Kwik Fit regularly. Has anybody ever experienced the same problem?

Thanks

K
