The EBC flagship sintered streetsport pad that delivers highest braking power, stability and long life.

Most manufacturers build bikes using sintered metal pads and these are direct replacements for that technology with several differences. First the refined compounds researched and used exclusively EBC are second to none in terms of quality of materials and workmanship. Secondly almost all EBC Double-H™ sintered pads use EBC design perforated stainless steel heat and noise shields on the reverse side, k
I have only ever used the FA447HH and never had a complaint always had confidence in my braking. When I bought the braketech rotors the Ferodo were recommended so I thought I'd try..
So it looks like EBC offers 3 types...
Track only
Street/Track
Street
I think I'll try the Street/Track (EPFA447HH) first thats one up from what I was using.
I'm still not completely understanding the "Sintered" and the Double H.
I did come across this which explain the high pitch sound I use to get, and I like as it's another indicator of how hard I'm braking.
