after i take a really sharp turn i notice i loose brake pressure but it seems to come back after i pump the pedal, this is only street driving but i have an event coming up and i was wondering if any one had any insight it has new aem pads and new power stop drilled rotors thanks

 

sounds like air in the lines. try bleeding your brakes. if necessary, go with a higher temp brake fluid. motul?

 

From what you are saying, it does not sound like you are fading your brake pads, per se. It sounds like your are either developing air in your brake fluid (unlikely on the street with a high-performance fluid), or that you have a failing master cylinder. You would need to develop interfacial temperatures (between the brake pads and the rotors) of over 1000F for extended periods of time to boil a high-performance street fluid, which is highly unlikely on the street.

I would check your master cylinder.

The exact same thing is happening to a friend's NX2000. He's replacing the master cylinder this week.

 

yup, agree with above. Get MC checked out before heading out to the track. Actually get it checked out immediately...

 

I bleed the brakes before and after evey race and even in normal traffic i felt the pedal go down a little more than it should and i bled them after that and air did come out so its acting like its boiling over but its not reaching temps hot enuf im only using the castrol gtlma fluid but where can i get the motul?

 

You should certainly not need Motul for street driving. The problem is elsewhere.

To answer your question though, motorcycle shops often stock it.

 

thanks for the info

 

If i replace the master cylinder do i need to replace the booster as well?

 

I used the Castrol GT LMA for autox and street, it worked fine for me. You should not need to replace the booster as well unless the booster itself is shot.

 

I had a similar problem in my 92 teg RS. I found that it was the brake booster afterall.

 

I replaced it last night and it seems fine now and has a more firm pedal though i think i still need to bleed it some more
