brake fade

I'm getting brake fade after just a few laps on my '02 GSXR 750.
I've tried bleeding (many times), EBC HH, EBC HH R1 pads, & Vesrah RJL's.
Any help would be greatly appreciated.
Thanks

 

Try using a scotch-brite pad that works on a drill and scrub the
hell out of your rotors for about an hour or , just take them and get em glass-beedblasted. (repeat often)

 

Flush the system and bleed useing a high quality fluid like Castrol SRF.

 

tjr-

Let me ask you, when you bleed the brakes,
is there any air in the lines? even a very small amount?
I ask because, last year our Gsxr 600 had the same problem.
It would get progressively worse in the ensuing laps.
Everytime we bled the system, we would purge a very small amount of air. We looked at almost every bit on the braking system,
but couldn't find any leak, at least not apparent at first.
We cleaned the rotors, inspected the lines several times and all the connections, replaced all the crush washers, tightend all the connections, rebuilt the calipers, installed a new master cyl.
...all for naught.
We tried almost everything! Except....
replace one of the brake lines. Unbelievable, but there was a hairline crack, and I mean hairline on the front braided line.
The lines were only a season old and had never suffered any
crash damage. weird, but it happens.
You could only see it with a magnifying glass. It was only after all
of the above that we decided to go over the entire system with a magnifying glass. So, if your purging any air check all all your lines and connections. If this isn't what you are experiencing...sorry I couldn't be of more help.

 

Thanks projekt9,
As a matter of fact, I do get a few small bubbles when I bleed the sysytem. I just thought that I hadn't done a good job the last time and that "NOW this succa will stop fading".
I will try that next.

Thanks

 

projekt9,

Will you share with us what brand of brake lines you found a crack in. I have recently had the lever come back further than it should on a '01 GSX-R600, only to work fine later. It would be interesting to see if I have the same lines as you had. Did you switch brands of line after your discovery?

 

...warped rotor maybe....

 

Joe,
I can't remember off hand, but I will go dig through the receipt pile and get back to you.

Dead Horse! They all do it. If you find the cure you'll be a rich man.

 

Here's a lesson learned tuning for expert roadracers. Stock pads come with metal plates behind them. I've seen many many a rider, tuner toss these as being no account. WRONG Those metal " backing plates " act as heat sinks, absorbing heat placed into the pad and keeping it from reaching the piston, which subsequentially cooks your high speed Dot 9 race only brake fluid, cooks your piston O - rings, causes that drag your all trying to eliminate (expansion) and causes the glazing of the pads you refer to as brake fade. Hope this helps. Keep the backing plates and EASE your pads in during practice.
