Here is a question that the dealership couldn't give me a clear answer on.

What is the exact difference between the 2K1 braking system and the 2K2 braking system? If it is only the rotors will they fit on the 2k-2k1?

Would be nice to see the braking distance numbers to get an idea of how much better the 2K2 brakes are if at all? Also wanted to find out what the difference really is on them for any potential upgrades.

Please no smart *** and smart *** wannabe replies.

 

The 02 max I believe has a electronic brake distribution system. What this is, is each brake has it's own brain, if only one brake looses traction and it will go into ABS mode, the other brakes will continue to brake normally. I beleive any combination of brakes going into ABS mode is possible. I think the advantages of this system is clear.

 

Very cool! So the rotors, calipers, pads etc.. are the same as a 2k1? I wonder if it can be installed on a 2k1 and if so how much?

 

It would probably be VERY expensive and time consuming to do. My guess is you would have to replace all of your brake sensors and your brake ECU, even the ABS unit and lines would probably have to be changed. I bet the project would cost close to 2 grand. That's just a guess though, it could be even more or maybe less.

 

Thats what I thought too! There seems to be excellent value in a 2K2 Max for sure! I am going to check some basic brake component part numbers sometime this week on the 2k1 vs 2k2. Anyone who has already done this or can do it easily please post your results. eg. rotors, calipers, pads, anything different on the brake system...

 

I assume that the Max shares the same sized brakes w/ the I35. Besides the electronic gimmickery, the only thing I know for sure is that the front brake rotors are larger, 11.75" (i think, should be posted in the infiniti website, but of course, not at the nissan site)

No need to get EBD if you just want the larger rotors. Same for the sensors, ABS ecu, etc. Hopefully Nissan is using the same calipers, that way you'll only need the caliper brackets and the rotors, maybe brake pads if the rotors are thicker/thinner.

 

Maybe not so clear.

Just test drove the IS300 5spd today and it, too, has EBD, only Lexus touts the thing as 'intelligent'. Measures speed, pitch, yaw, how fast the brake pedal was depressed, etc. to try and 'determine' if the driver is going into panic braking. If the computer thinks so, it will apply the maximum braking force. Lexus' argument is that research shows the despite the abundance of ABS, a lot of people are still not braking hard enough to avoid collisions because they're afraid to lock their wheels up, thus defeating the purpose of ABS. (The insurance industry confirms this. Ever wonder why that ABS discount keeps getting smaller and smaller?)

So carmakers are introducing this 'feature'. Only problem is when you drive semi-aggresively, the system goes into this mode far too often. The IS300 has this problem and the ABS kicks in way too early.

Maybe it's just me, but if you're about to slam into a car/wall/person/etc. maybe, just maybe, you'd try and stop as aggressively as possible. If a person can't grasp this idea, maybe reproduction shouldn't be an option for this person.

 

Just for everyone's reference. There's a difference between BA (Brake Assist) and EBD (Electronic Brakeforce Distribution)

BA is what mhgsx is trying to explain (based on how i understood his post), in that the computer will depress the brakes in an emergency situation where people tend to let go of it and thus negating the advantages of ABS. I've already had the priviledge of utilizing this feature once when a guy in front of me just suddenly braked for no apparent reason in a 45mph strip of road.

I couldn't swerve to any side (no space) so i just hit the brakes with all my might. At first it was the usual force i needed to apply but around halfway through the brake pedal just seems to go down on itself (it was as smooth as a hot knife on butter).

At this point the car even felt like it braked harder and stopped a lot quicker (e.g. abrupt).

To continue,

EBD is where the computer applies maximum braking force to the wheel that needs it the most. In certain cases (if not all) it applies it to the side/corner of the car that has the most weight (stronger force of inertia/momentum)

Fortunately, EBD, BA and ABS is standard on the Maxima so you get the best of all worlds.

 

Sorry to be digging up an old fossil like this one, but can anybody tell me how much electronic stuff is in the 2001 20AE brake system other than the basic ABS? It's an early car (was built during the transition month for rear brake pads but takes the ones for cars built before 10/00) and has a 5-speed manual tranny, if any of that matters. Based on ~75000 miles of driving, I don't think that it has EBA, but I'm not at all sure about the EBD.
