Just like to point out that most OEM brake pads ARE sintered.
stupid question alert what does sintered mean?????

It's a manufacturing process using powdered metal particles and bonding agents under heat and pressure to form complex shapes , it's a form of casting.
See , I did listen at college :I can't believe it's not butter!

They make the friction material component of the pad using a sintering type process instead of the old fashioned method of mixing asbestos , gun metal , carbon black , chromium and various other materials to form a powder mixture which was then heat / pressure formed into pads directly onto the backing plate using presses and dies.
I served my engineering apprenticeship at Mintex , they were (and still might be I don't know) the biggest manufacturers of braking materials in Europe.
Non - asbestos pads were in their infancy when I left Mintex , I think there are very few friction materials now that still contain asbestos , it's all powdered metal (sintered) pads these days.

To cause (metallic powder, for example) to form a coherent mass by heating without melting

You remind me of somone else when you say things like that!!yelloisfriedegg wrote:I served my engineering apprenticeship at Mintex , they were (and still might be I don't know) the biggest manufacturers of braking materials in Europe.

Quite a lot of motorcycle components are made by sintering , brake and clutch levers for example , thats why they have that odd granular look at the break if they get snapped 
footrest hangers , footpegs , almost all the complicated little "castings" that you take for granted , it's quite a cheap and quick manufacturing process so very popular for lots of things , not just bikes.

I hope you don't mean the person who sent me another stern pm this morning

bloody hell, its a wonderfull mine of information on here today!
so if its a casting process, surely all pads are sintered?
(which is what you just said....... see i do listen even on my days off!)

To be pedantic, during casting a molten alloy is poured into a mould. During sintering, particles are mixed then heated in a mould to below their melting point and subjected to pressure so that they fuse together.
The more traditional method for brake pads is where particles are mixed with a binder and moulded onto the backing plate. I understand EBC green pads are made this way.
Pads are usually graded due to hardness, irrrespective of the manufacturing process. Having said that, sintered pads are USUALLY harder. There are pros and cons. To simplify soft pads will give more feel but fade. Hard pads more bite and less fade. Hardest pads (recomended for racing only) need to be warm before they operate effectively.
It can be useful to have a soft compound on the back brake which I use more in wet conditions. I have found EBC sintered on the front and green on the back to be a good compromise.
You pays your money and makes your choice. IMHO the safest option is to stick with ome
