GT3 brake/clutch bleed


Recommended Posts

I searched the GT3 forum but couldn't find a definitive answer. Are there any caveats specific to the 996 GT3 vs. a regular 996 C2?

It's my understanding that the procedure for the brake/clutch bleed is no different, and I plan on using the Motive Bleeder with ATE Super Blue/Typ 200 Gold.

I'm simply looking for a little confirmation, especially on bleeding the clutch. You know how it is, wondering if the clutch pedal will "rebound" after you depress it! :unsure:

Surely if your front rotors are showing signs of stress, then bleeding the fluid will not help. If anything this is a sign that the fluid is good and the brakes are working real hard to trash the rotors - if the fluid was boiling then you wouldn't get good pressure on the rotors and they would in effect last longer?

Think its a fact of life with stock rotors - in the UK where we have 5+ years of GT3 experience a lot of people are changing to floating grooved rotors to try and solve the cracking problem. The other solution is to buy Cup rotors which are thinner, and half the cost - but you are replacing due to cracking rather than wear, so this seems to be a good solution.

IMHO drilled rotors are for cosmetic effect and not actually any good on track as the holes are an inherent weakness in the rotor.

Just bled my brakes with the Motive- I always finish with one or two pumps the old fashioned way (hard to teach a old dog new tricks) but have never been sure about the clutch. Do you pump it like the brake and then open the valve? With the pedal to the floor or do you push it to the floor with the valve open and then close before letting up so you don't get any air in?

Hey RJ, I just did this exact procedure this past weekend, so let me know if you still have any questions. How was the DE at TWS? We had one up here at MSR, and it was a blast! I got the same tires that John has (the Dunlop SSRs), but the rears are only 265 unfortunately. Still a great improvement (especially helped with a rear sway bar adjustment due to the narrower tire)--
