Okay, so I was looking for large brake kits, and I noticed that ONLY for the front rotors/calipers did you have to worry about "non-abs" or "abs"

Now does this mean that the ABS system in the S13 is only a 2 channel front brake ABS system, and it doesn't work on all 4 wheels?

Because I really like ABS, and before anything becomes crazy, There is NO one in the world that can modulate brakes as well as a 4-channel ABS system no one, unless if you got 4 brake pedals one for each tire, and 4 extra legs/feet for it :)

Because it sounds really stupid when you lock up the rear tires, but you don't lock up the front :/

If anyone was wondering, I was looking at a 12.2" slotted vented rotor with 4 pot clalipers for the front, and 11" blank vented rotor with 2 pot calipers in the rear, with brakes like these and some hard braking I could see tires locking up, and there is a nice flat spot in your tires.

So who has knowledge on how effective it is? This seriously could be a deciding factor on if I get this car or not :(

it's a 4 channel ABS system.

The reason why there are ABS and non-ABS brake packages out there for the 240's is because they changed the front rotor size for ABS equipped cars. For instance, the convertibles got the larger rotors and pads per the ABS package, but we didn't get an ABS system.

I haven't driven an ABS equipped 240 yet, but from what I understand, it's not as effective as a more modern system (that's just the knowledge of the time showing).

Well I'm not expecting it to be super effective.

But I found really affordable 15" rims (that will be used for winter) that will fit over the 4 pot 12.2" brake system I want :)

The abs system on 240's suck.

When I happen to lock the wheels, I think it's more effective for me to press and release the brakes rather than leave things to the ABS.

I've never locked my brakes in my ABS S14, and I have hit them very hard going fast. Maybe I'm just lucky?

the front lock up first, so you just go into a dead slide, i have done it on my non abs s13 and it is NOT cool at all. pretty scary going 60 on a 2 lane road. did it at night too, and you loose all stering imput, etc. when you feel the abs come on the brake pedal goes insane, at least on the accord we did it on. and i think that the lock-up sensor on the s13 is built into the drive shaft, not sure though, if anyone knows...

i do fine w/o abs, i never get to the point were it comes on, save once. id say go with bigger caliper and no abs. abs on these will sound like alot of fast chirps-they still lock for a fraction of a second each time theabs pumps it. oh, whichstate has the highest auto insurance

what brake system are you looking at?

I love ABS. Its saved my @$$ many times :). I have no opinions about whether the 240 ABS is good or bad compared to other cars with ABS, because this is my first car with it. However, I do hold to the idea that there is absolutely no way anyone can realize their wheels are locked, pump the brake, and stop, quicker than the ABS computer can.

There ya go.Bottom line, if you can get a 240 with ABS, why not? Don't need to use that as a make or break sellpoint, just good to have I think. With drivers like they are around the beach here, it's saved me more than once. I'd imagine, though, a front brake upgrade could help quite a bit too.

Well it doesn't matter for insurace :)

Insurance for me 19 yo male, 1 accident, 200 deuct, 1 million third party liability, mods or no mods for a 1988-1991 180SX will cost me $1400 CANADIAN a year for full coverage, and if I mod my car, as long as I have my bills, photos, they'll cover me for those too :)

w00t go public insurance go :)

But I think I'll be going with ABS, since in the end it makes maybe 5 dollars diffrence from where I'm buying from :)

I beg to differ on a 10+ year old ABS system.

Perhaps the majority of drivers on the road. They are too busy talking on their cell phones and spilling coffee in their laps. Perhaps a bit more practice is in order?

Well I've never tested a 10+ year old ABS system :) But I'm pretty sure modern day ABS systems kick the crap out of anyone today, when they try to modulate breaks. Ie ABS is now really bood that I don't think anyone could compare their pedal modulation to it.

It's been shown that ABS cannot stop quicker then a human. Naturally, this person is at a much higher skill level than most and myself but none the less it can be done. I am somewhat bias though as I really don't like any type of electronic aids. I've found some ABS systems interfere with what I planned on doing. Due to a software problem or just poor implementation. My ABS and traction control are my right foot. Save the equipment for someone else.

i definatly agree with llamabeta on electronics, i dont like abs traction control, skid control,ect... if i want to loose traction, ill be damned if a computer has anything to say about that. :)

I just want to reinstate that ABS is good, but not on such an old car. On more modern systems, the abs sounds like a loud fart. On my 240, it makes a clicking sound... junk.

And the only way a person should be able to lock his tires in daily driving is if he's trying to stop quickly in wet road surfaces. That's when you should realize that you have to pump the pedal instead of slamming on the brakes when you need to stop quickly.

ya, on my brothers accord, it sounds like just that, a loud fart, with lots of shaking.
