Hello, i have a Nissan Maxima SE 04, recently had problem with the brake system: When driving, and need to brake, when pressed the brake pedal, it goes to the bottom, and makes some strange sound, coming from the area of the booster, i have to release, and press again to get stopped, also came on brake light, ABS and, VD, TCS light. Problem is, that Nissan dealership, do not receive my car, because is modified, i made it an armored car, adding 700lbs extra, and has installed drilled-slotted rotors. You must understand, brake is an important issue, trying to stop this "tank"
Hope, my english was good enough to explain all the issue!
I will like to know, if somebody experienced some brake problem similar to this? if yes, did you find any solution? Thanks!

I look for it at ebay but only found it used, not even rebuilt.
Any suggestions?
