De-glazing pads

[Scooby_Greg]

I've managed to glaze my pads after a reasonably spirited drive at Goodwood Does anyone know of anyone that is able to de-glaze pads?
Thanks!

Thanks Alyn, The brake performance has dropped off significantly and the pads appear to have a thin harder layer on the surface. I have not checked the fluid yet. I was not aware you could do this as a DIY fix. Will just be a case of filing off the top surface?

Filing sounds excessive.

I would use a good quality aluminium oxide paper P120 grit wrapped round a flat piece of wood or metal.

Or put the sheet on a flat surface and rub the pads on it, keeping them as flat as possible.

a piece of glass or plate steel as above is just the job...........

and stop driving like a pussie

Thanks all, I'll give it a go. Had Googled it but wasn't sure if that was the best approach.

Alyn, brembo calipers, PF discs, brembo sport pads (discs and pads kindly supplied by ASP) Bedding procedure I use is 300 miles with gentle use of brakes, then a couple of cycles of 5 moderate uses of brakes from 60 to about 10/15, where able to do so safely of course, allowing to cool between the 2 cycles.
Is this right? It's what I've always carried out....

Well, the pads still seem not to work very well after deglazing and running in-twice. Checked everything else and rebled them just in case, so I suspect I just fried the pads (they are supposed to glow red on the track aren't they

So, are there are recommended pads you would go for? 2500s? EDC? (I know Steve PPP likes melting these) The issue I have is the car is used for both short journeys and may occasionally have a few gentle track days. Therefore its hard to choose a pad that has good performance and bite from cold, but also can perform when used on track. I didn't like the PF Z pads as they didn't perform when cold for me, and the Brembo Sports perform fantastically from cold but obviously don't like getting very hot.

I love the pagid yellows on my M3 but not sure if you can get them for the hatch brembos?

Sorry mods - I should have put this under wheels, tyres and brakes in the first place.

you have to cater for the specific pad material but the HP sport pads would bed in with moderate use within 100miles, then gradually increase their load over the next 50miles - no short, sharp shock with these

as for the rs29 then yes they are available for the STi Brembo calipers, as are various PFC, Ferodo, etc...........
the new 08 PFC material is very good and being metallic based will allow far higher temps than organic materials (like Brembo/Pagid) whilct having a good range ot bite...........

Sorted..

That confused me I was just moving it!

I've been running DS2500s for about 5 years now, both in the std callipers and now the APs, I won't use anything else despite many new 'next big thing' coming and going. Absolutely no problems from cold and you have to really excessively hammer them to get any hint of fade on track (not a hint at Brands or the Ring).

[Scooby_Greg]

Thanks all for your advice - really appreciated. Toss up between the 2500s and the new PFs. Looks like I will be calling tomorrow Alyn. If the 08 compound has better cold bite than the Z then I may be going for them. They will need to do Spa

Moi?

Still using the bluestuff NDX's on my ksports, love them on track and they took some silly abuse at Goodwood. Completely different to their behaviour in the 4 pots when they melted easily.

But i'd also be tempted to try something different next (DS3000s??) Been using the car this week with the snow and they're really numb feeling when cold. I've found myself using the brakes excessively at the start of the journey just to get some heat into them.

Dont the discs need a scratch down when new?? was told they have a film on them so if only deglazing pads the film/grease? on the discs would just glaze them up again??

[SpecB]

You should bed disks on old pads ideally.
