I'm running Hawk Ceramics on my A4 for the last 4 years, love them, no noise, low dust, great stopping power, pad thickness like new at 20K miles on them. Unfortunately, I developemd a clunk and found one pad broke loose from the backing plate. These Hawks were bought from Tire Rack, I immediately purchased a new set from TR and was amazed to see the large chamfers on both ends of all 4 pads. These pads are approximately 3 inchs wide with a half inch wide chamfer tapering at about 45 degrees to the edge. Yes I know that chamfers help with noise. But of the 3 inch wide pad only 2 inches of pad material is now going to be touching the rotor which equates to me a loss of 33% braking performance. My old Hawks did not have any chamafers at all.

So why the large chamfers and does this affect braking performance?

i will suggest you to replace the product so that u can again drive your car smoothly.

I did replace the pads, the A4 runs fine, brakes fine!

I don't understand your comment?


I'm asking why do brake pad manufacturers put such large wide chamfers on new pads anymore? It reduces the amount of friction pad to rotor contact surface which reduces braking performance.

So the old ones didn't have a chamfer and the new ones do? For the same application? Is there anything on the Hawkl web site that might explain why they changed this? It does seem kind of strange reducing the area of the pad. Of course, as it wears, you'll get some of that area back
