really disappointed with performance friction pads

HI
Yes you had the Z rated pads from us , usually get good feedback from these pads , and having driven with them , I have always found them good , a lot of people use them on the track which says a lot about them.
You might have glazed the pads , so would be worth taking them out and rubbing them on some emery cloth to take the top layer off .
We do recommend bedding disc and pad packages in for 300 miles of normal A & B road driving , this mileage is to bed the discs in more so than the pads , if it was new pads on old discs you can be a lot more aggressive on them , but new discs you need to bed them in for longer , we recommend to finish the bedding in process , to find somewhere nice and quiet and do some high speed stops , braking from high speed hard down to 20 , not to a complete stop , drive for a few minutes to cool them , then repeat , do this 5 times , then leave them cool off overnight , they should be good to go.
I would rule out a dodgy set of pads , as the pad material is mixed in fairly large batches , so you would have loads of people complaining about them.
We do sell a lot of Z rated pads have have no complaints really.
CL RC5+ are a much better pad , hot or cold use , they are very good ,these have very good initial bite , better than the Z rated , and my personal choice of pad , but the downside is they are more expensive ,and can squeal a bit in low speed use.
Discs will not make a difference as some have mentioned , the only real difference between discs is how reliable they are , poor quality disc would warp or crack quicker than good ones with hard use , or wear down quicker , but you don't get different grip off different make disc , except for the extra bite a grooved disc offers.
Hope this helps
Cheers Ian

so back in feb i sent my car to chevron for a complete suspension overhaul and various other bits which included new discs and pads all round.
i have brembos with stainless lines and fresh fluid. i went with godspeed single piece g-hook discs all round with performance friction pads.
now i did jump the gun back in feb by saying i wasnt impressed with them after my return trip but that was me jumping the gun. i have since followed the bedding in procedure and im still in shock at how bad they are.
even just pulling up to the junction at the end of my road i feel as though im pressing the pedal and there is nothing there,i honestly have 0 confidence in stopping should somebody pull out on me.,there seems to be no initial grab with them.
anybody else had issues with these pads? the ebc's in my old blob sti were 10x better than these.
could there be another issue? the discs/pads i had before i replaced with these were miles better and they were pretty much on their last legs.
im not having a stab @ godspeed, ian has been more than helpful and the service from his company was spot on.
ian if you read this would it be possible that the pads may be faulty?
to bed them in i took the car between 2 roundabouts, up to 70mph then hard braking down to around 20mph around the round about then same again, i did this around 8-9 times and i could smell the burning heat from them which i assumed is the de-glazing. i have now done around 500 miles so far with them. they did seem to get marginally better the hotter they got but i cant drive like that eveywhere.
car is a 2007 hawk sti running 350bhp road use

Yep. I had PF01 (from memory) and the cold *ahem* 'bite' is shocking. I almost overshot a junction, the first time.
Never again.
I'll just stick to the 'Honda CBR 600' of brake pads: the DS2500.
They perform perfectly fine - and straight from cold - in my AP CP5570 330mm brake kit.

If your getting 0 pad dust from your calipers then I would say your brakes are not working correct ,
Take the pads out & scorch them with emery cloth , then bleed the system with new fresh fluid , also checking your lines are tight ( pressurised) & remember you have 2 bleed nipples per caliper( brembo bleed nipples have the tendency to corrode inside the nipple housing clogging it up so if you do have air in the system it won’t bleed through correctly. It may. It may be that your calipers need a good overhaul strip & refurb to bring back up to acceptable levels of performance.

yeah bedding in procedure was done after 300 miles and roughly as you said although im sure the printed slip with the instructions said to do it 8 times which is about wjhat i done. i went around the round-about then built it up to 70mph ish then hard braked down to 20-30 then around the next round-about to head back the the other one and repeat. roughly 1/2 a mile or 3/4 mile between each one then i took a 10 mile drive home and left them overnight.
i will get mark @ tdr to remove them for inspection and give them a wipe with emery cloth.

+1 for Carbon Lorraine RC5+ pads. Great bite from cold and once they have some heat in them they are even better. Very dusty pad though and also does squeal at low speeds but to me braking performance is more important.

Bedding In of PFP should be done ( if you use new disks ) immediately , not after 300 miles . The nature of beding in , is to create a compatible intermetalic surface with the pads on the surface of the disks. If you crawl around with the PFP's for 300 miles and then expect a bed process to break through a glazed surface you probably will be disappointed. You have IMHO a choice , 1 Take some emery cloth (engineers cloth abrasive ) to the disks and rub hard for a long while to bust the glaze off. 2. Take some new disks and try again. If you use Used disks its advisable to do step 1 first anyway.

Brakes are fine now guys, I never did anything else to them and over a short time they became 10 x better. Dust is minimal and they often squeak after a wash but other than that they are bang on and fine for my fast road car.

I use PFC pads. I had one pad though that had a slice of material shear off the face of the pad (front). This was after 12 months but the fronts were making a grinding noise. I sent pictures to PFC and they were not interested. Funny thing is they said they had never seen this before and told me to destroy the pads. I found this strange as I would want the pads back for inspection especially as they have never seen it before. So I was out of pocket. Pads still had >1/2 material left. So they may be good (which they are) but their customer support is terrible. Ian from Godspeed said he had seen it but usually on cars that do not get used much and the pads sticks to the rusty disc and pulls a chunk off. Makes sense but I use mine daily so that was not the issue for me. Unlucky I guess. I did replace with another set of PFCs BTW.
