Had a frightening experience at the weekend. After about 3 or 4 heavy braking sessions from a speed I don't care to divulge I had a brake fade to end all fades, a proper brown trouser moment. I'm currently using EBC yellows on standard 4.5 rotors. Never had this problem before but maybe I just never hammered them hard enough to show it up. Anyway I'm looking for advice on some pads that are more up the job of handling my very infrequent right foot excesses. Advice please!

I never had any fade from my yelowstuffs. Maybe you boiled the fluid?

Rotors?

Do you mean discs old boy?

Would think your fluid is at fault rather than the pads, but it would do no harm to de-glaze them.

Rotors..., sorry, been working with too many yanks.

I doubt it's the fluid boiling as the pedal remained firm but it just ceased to slow down. On closer examination all the holes in the disks are blocked with brake muck. Maybe that is part or all of the problem. Problem is that to reproduce it requires speeds that usually equate to handcuffs. Good excuse for a track day I suppose.

how do you go about deglazing disks?

Not the discs, the pads.

They need taking out and rubbing on a roughish surface. Concrete floor should be ok.

If you boiled the fluid, then your pedal goes to the floor, if your pedal stays firm, then your pads have effectively melted and these then start to lubricate, rather than grip the disc.
Look at the compound when you take them out, and i bet they are smeared.

I had Yellowstuff pads actually warp as well as glaze on my Cerb so it is possible that the pads themselves are at fault.

In my case it was after some enjoyable twisties in the south of France so there was probably a combination of extra braking heat and extra ambient heat ..... although I'd say it was mainly braking heat biggrin .

Redstuff in it now.

I did put Carbon Lorraine on it for a while but found the compound I got was too aggressive for the standard discs (I think the newer compound ones are softer though).

The RC5plus replaced RC5, and is alot kinder on discs, also less noisy and dusty.
RC6 is hard core trackday/racers, the hotter you get the pads the less they wear discs, because the metal content becomes more malleable with heat.
