Digging up another old thread!
Another track day gone by and after having followed "bladeracer"'s advice, I've cleaned my brake discs thoroughly with wire wool and brake cleaner (which is basically a powerful degreaser) but my brakes are still crap for the last few laps of a 30min session.
A quick recap of my brake setup:
- Motul RBF 600 which is changed before every track day.
- EBC HH pads
- Standard rotors
- Standard master cylinder (read https://www.fireblades.org/forums/hon...der-929-a.html
to know why)
Lets assume I can pack in 12 laps in this session:
--> Laps 1-9: After warming up the pads before a few corners, the braking power is there although the initial bite isn't brilliant but its probably because I'm not being too aggressive with the lever.
--> Laps 10-12: There is no sponginess in the brake lever, it remains hard and I can almost feel the pads pressing up against the discs but its like having pads made of wood....the pressure is there but the friction coefficient is almost gone. I need to start using 3 finger braking to get more force on the lever.
I've spoken to a few of the mechanics on hand at the track day who help out and work for some of the racing teams and their guess is that the pads are just heating up too much and starting to go beyond their working heat envelope.
They suggested some top of the line Brembo pads which are way too expensive although some slightly cheaper ones are also available. I personally don't want to be lead by whatever they want to "sell" so I've done some research and found some Ferodo pads which seem to be quite good, the Ferodo XRAC: http://www.ferodoracing.com/it/motor...ay_cooling.htm
