I never have any pulsating. I'd guess that your car's problem is probably a little easier fixed over replacing the whole brake system. But thats your call.

I'd hate for your to replace the brakes and find out it was something else, like a bent rim or blown shock, that a whole brake system upgrade isnt going to fix.

Good luck!

What could cause the rotors to warp. Bent rim? I thought this was looked at already, but I will have a second opinion. Malfunctioning shock? I don't have the tech expertise to have this looked at and live in Los Angeles. Would anyone know who I can take the vehicle to have it fixed. I keep going through rotors. Dealer has replaced the 3rd for free (that is after I bought new pads since this was a requirement to have it warrantied out).

No, warped rotors are not from a bent rim or blown shock, but pulsating brakes could be an indication of either of those (among other things).

What I am trying to say, is if you DONT know what is causing the pusating sensation, make sure your not trying to fix a problem by addressing something thats not actually the problem.

It sounds like you know for sure though, that the rotors are warped? its easy enough to test, they have lathes that can spin a rotor and check for warpness, of course those same lathes can be used to cut material off (mildly warped) rotors back to a no-warped state.

Basically the only thing that really warps rotors, except for factory defect (which isnt likely), is excessive braking, which generally isnt done on the street, but instead on the track. Was your car ever tracked? You need to get a LOT of heat into a set of rotors to actually warp them. (in most cases).

Lamborghini upgraded the steel rotors starting with 2005 Murcielago with 8 piston calipers and 15" rotors. Lamborghini started offering CCB on 2005 Murci with 6 piston CCB calipers and 15" CCB rotors for fronts. The steel rotors have 14" in the back and 15" for the CCB. That's why you need to change your hub in the rear because CCB is 15" vs 14" for steel.

We have a Lamborghini OEM CCB conversion kit for 2005-2010 Murci. this upgrades Murcis with Steel brakes to CCB brakes.

This is what I thought. After an appropriate break in period, pulsation begins after slowing down from speeds of 140 MPH several times, or from track use at moderate speeds such as 100 mph max speed. If this is normal than I would probably need to upgrade to better brakes. What I am being told by dealer and other Murci owners that high speed use or tracking vehicle will not cause pulsation. The pulsation goes away after resurfacing and replacing rotors. Also pulsation is mild, albeit annoying.

the steel brakes on the murci works wel, especialy on the LP640 where the latest evolution is mounted on. But they are ment for normal to sportif driving. If u take it to the track or do some excessif braking from high speeds (even 140MPH) the brakes don't have time to cool off in between to avoid pulsating feeling. The pulsating is not a problem when u change regulary the brake fluid (this heats up also)! But when u do not want this pulsating feeling i stongly recomment to think about upgrade to CCB, They are perfect for track use or other extreem conditions

How much would it cost to upgrade. Who would do it. Should I go to dealer. Or is there a reliable company in LA. Brembo has an aftermarket rotor system that works with standard rims. The big brake system would need 20 inch rims which I do t want to do.
