Yes but you have such a priveleged upbringing you sound like any other southerner. You live in the midlands. You are a midlander.

Jay, if they weren't bedded in properly from the start, you didn't need to overheat them to have them melt their resin all over your disc. Normal operation will do that and you'll have the "glazing" mentioned above in Pagid's info. You've a solid mounted caliper, so even a few thou of deposit can feel like the car is trying to shake itself apart.
10 minutes in the middle of the day (assuming the space and lack of traffic required), unless he's based on an airfield isn't really enough to bed them correctly IMO and what you've got is the result of that failure to boil all the resin out. Any pad you buy will suffer the same problem if you fail to do it likewise... Unless you go for a fully sintered one, like a Carbon Lorraine.
Take the car out at night on a quiet length of bypass etc and warm the brakes with some general use, then do 5 60-20 stops, drive for a mile, do 5 XXX (ahem) to 30 stops, giving it full beans back to XXX after - you should feel the brakes fading, this is correct. Drive for a few miles, doing some more small stops to cool them gently, rather than quickly. Arrive home and leave them to go stone cold till morning.
This should be enough to remove the build up and any remaining resin in the pads.
If it does take a set of new pads and discs to resolve, then be mindful of doing the next set properly.

Ok man, I'll try that.
Again i didnt go with alex as otherwise he'd have had to lock up etc.
There is a bypass 2 minutes from Alex's unit so i assumed he went on that. That being said i cant be sure Alex did it correctly other than trusting him.
I will do as you suggest and see how it goes :-)
Think it may also be a good idea to sand the discs down (both sides).
tony_danza:
I don't mean to sound like I'm having a pop at Alex, I'm sure he gave it a good go and maybe to a method he's used on a different type of pad that worked ok.
Some are, as you say, more temperamental than others and need a very defined bedding to stop problems.
