Hi, Shawn -gulfxray said:That's a good price! Thanks Dick... You little bargain shopper!
Joe's got it right. Just to add a bit from a few years (ok, decades) in brakes for planes, bikes, cars, WRC, HRC, NASCAR, Indy,...blah.. blah... etc....The organics and semi-mets are both held together with a thermosetting resin of some kind. The resins have a nasty habit or reversing themselves under high KE, so the pads crumble or sluff junk on the rotors. Brake engineers like me call this DTV, disc thickness variation. At triple digits this really sucks. The symptom is shudder or pulsations. Most bike pads are now sintered due to this issue. Notable exceptions are the rear of the GT (like Joe and I now ride) is NOT sintered. LT is sintered both front and rear. The organics and ceramics from some top firms today are really awesome with very linear torque over very wide ranges of operating conditions. Unfortunately, high load and high temp tend to bring out very non-linear behavior and this happens quickly with a tipping point style rate of change. Simply stated, they may be great then give up fast on you. Hawk, where I was president of their Performance Group, makes a ton of aircraft, clutch buttons, and motorcycle pads for Brembo...sintered. Now OE on Ducati and Aprilia. The newest Hawk sintered has some very good characteristics. They may launch an aftermarket line in 2007. So far, most of their work is OE, for example HD is mostly Hawk sintered pads in Hayes calipers. Hawk is now one of my clients.messenger13 said:Brake pads are normally available as organic, semi-metallic and sintered. Organic pads contain no metallic parts; semi-metallic are a mixture of organic and metallic parts; and sintered metal pads are made completely from metal. Although sintered pads typically give you optimum stopping performance, they also cause premature wear of the rotors. On the LTs, I found non-sintered pads worked just fine.
If I remember correctly sintering is a process to form 'something' by heating it but not heating it to it's melting point.. I would guess that the metallic pads are formed using this type of process.. so you could have 'metallic, 'metallic sintered' and organic..ksailor said:I remember reading a thread long ago about Sintered vs. Organic (Kevlar) break pads; I'd like to know in layman's terms what is the difference? I'm replacing mine on the 02 with 25K miles.
This is not an attempt to create another oil or tire thread.
Back in '07, when this thread ran, they were in Plano. Maybe they moved since then? Dunno.sydvicioustx said:Were they in Plano doing a show? I just emailed and they said they're in KY. I live in Lewisville and was going to drive over to Ron's to pickup my pads.
You are right on.GlennM86 said:Having just read most of the archived brake pad threads and just watched the Paul Sayegh video #3. At time 52:10 Paul shows the package for the EBC FA244HH Sintered break pads. He had just finished modifying the brake pads by grinding a corner off.
Why does Paul use the EBC FA244HH and not the FA304 (or FA304HH) as discussed in the dozens of other threads?
Was the video made before EBC modified the rear brake pads to actually fit the bike?
The bike may use the same brake pads with Brembo calipers...GlennM86 said:The Ron Ayers site lists the EBC FA244HH for the Aprilia.
The HH denomination os for sintered.GlennM86 said:I thought I understood the part numbers, Sintered vs. Organic, Front vs. Rear. I truly like Paul's videos and advice and now I am confused again.
Any and all help is appreciated.
