Worst one I had was on a CX500 round the back of Wembley Stadium. Got a placcybag round the front disc which pushed the pads out slightly - first grab of the brakes as I approached the roundabout did absolutely nothing. Brief moment to regain control of the sphincter and had another grab at the brakes which then thankfully worked.

Just a thaught. Could the skim have affected the discs? I've lathe skimmed discs myself, but have never found the result to be as good as that to be had from new discs. Even using a tipped tool it was evident that there were hard (chilled?) areas of the disc that had a different finish. My understanding is that professionally skimmed discs are ground both sides at the same time, thus ensuring that they have a consistant finish and thickness. Then again maybe the discs I turned were particularly bad to start with, and you've turned discs before without problems. BTW the lathe I used was a Colchester Triumph, so should have been rigid enough to do the job properly. Mike.

I've used Ferodo Premiums on the Saab the last couple of times. They seem crap when the discs are cold, and fade a little, when the discs are hot, but used repeatedly. A couple of fast hot stops are enough, and they work great, after that they start to go a little soggy. Won't be using them again.

For a moment I had visions of a YTS trainee - or whatever they're called now.

Apparently they can even turn up as fully documented Aero engine parts!

If the YTS equivalents nowadays have the good looks and intelligence that they did a few years back, the "well-shagged" will be happening only in his dreams....
I did a work placement during my degree at TVR in Blackpool. The YTS-type lad there was legendary for his, ummmm, mishaps. He's had all the usual things done to him, poor thing ("go to stores and get me a compression will you - aaarghh, you've let it out the box" sort of stuff), but his crowning glory was his adventures with a certain bolt.
At a certain point in the floor in the R&D workshop there was a bolt. It had been used to hold down some piece of equipment in the past, and was now stuck there. Everyone just knew it was there, and avoided it.
Except one.
One person was always tripping over it. Again. And again. And again.
So one day, he has a bright idea. "Perhaps if I could see it better, I would be able to avoid it", he thinks. So he traverses the workshop to get a aerosol of red paint. He walks back to the bolt, and sprays it. He returns the can of paint to its rightful place. He then goes back to his work.
And trips over the bolt.
Muppet.

It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Peter Hill saying something like:
Bedding in 60 - 5mph 5 times or so is something I'd do with a set of decent motorcycle pads or performance car pads, but is utterly unnecessary with ordinary car pads.

**-** ( snipped-for-privacy@tamate.com) gurgled happily, sounding much like they were saying :
"Apec" or "Abex"? Abex are one of the suppliers that GSF use for PSA pads, OEM for some, I think.

As you say, the Ford ones are good, as are standard Mintex ones I have on my Focus at the moment though they make quite abit of dust on the alloys, but allow the car to pull up well from high speed without fade.

Google does a good job for me.

"Abex Friction Products, We heartily recommend the ?bedding-in?process for all applications from STANDARD passenger cars to emergencyvehicles" and "Pad bedding is needed for ALL types of pads (i.e.non-asbestos organic, semi-metallic, carbon-metallic, ceramic metallic,etc.)."
I think the paragraph that follows that line which describes 'green fade' sums up your problem. OK that's a kitcar site and you will dismiss the terms STANDARD as meaning PERFORMANCE and ALL as meaning RACE.
Maybe it's just Abex?
Try this link to a Bosch pdf document from downunder that also gives a similar though slower speed bed in process on page 7. "NEW from Bosch ae the PRO PLUS and ULTRA range of brake pads for passenger and light commercial vehicles to suit most vehicle applications" - again it doesn't read like race pads to me, typical "branded" replacements just like Ferodo.

Seen a comment on a forum that suggested it would soon become an installer job to bed pads in - more likely in the USA (land of the free) where brake fitting is more regulated than here. If that happens it will become a roller brake dyno job, not out on the road. There is a TSB on Nissan brakes in the US that instructs the fitter to bed pads in on the road on some early 90's 4x4's to avoid later comeback for pulling unevenly as new pads start wearing though old rotor's anti-wear coating.
New regs have resulted in changes to pads this year, especially low end ones. UK punters may well be allowed to drive off with brakes that will die the first time the brake force assist cuts in.
