question on some parts and info i need for my abs deletion

[ccollick13]

Ok i have a 2000 audi a4qt and my abs module has failed, so I'm just going to delete all my abs since i do like driving more with them off. I'm just going to run one output to the front brakes with a T and the other to the rear with a proportion valve as well. I'm still learning how to build my car so I don't know to much about parts. my question is what type or brand proportion valve should i use and does it matter what type brake lines and tee i use. one last question since I won't have abs will i still need a vag-com to bleed my breaks. I'm thinking no since i don't have to worry about air getting in to the abs at all. but please correct me if I'm wrong.

I have been doing a little reading up on this as it might be an option for me in the future. It seems only some guys use a proportioning valve, others do not.

Also, no, vag com will do nothing for abs if there is no abs

You'll need a portioning valve, for sure. The braking system uses the ABS controller to portion out the amount of pressure to each end of the car. In a failure or removal situation, you'll have more pressure going to,the rear than is ideal for any type of driving.

[ccollick13]

do u have any recommendation for proportioning valve.

[ccollick13]

and are there any 4 port master cylinders that would fit my car. think about doing a 4 port master cylinder instead of using a tee.

In case you actually want to repair your module....http://cheapabs.com

$99, had mine repaired there 5 years ago, and it is still going strong!

^^ This.

Why don't you just rebuild instead of doing all that extra work? I had it rebuilt by modulemaster some 2 yrs ago and its working like a champ.

I just never wanted a car with abs.i really do like not having them on and still have yet to lock my brakes up.

Your braking too early then. :p

Check your fuses also. You definitely need a proportion valve. Driving my b5 in the snow last year was mad sketch. Had to gear down to stop as the rears would lock immediately.

Plus, anybody who has a decent amount of legitimate experience trying to set fast laptimes will know that you can out-brake the ABS. See here: http://farnorthracing.com/autocross_secrets9.html

At one time I thought "who needs the ABS?" and considered deleting it. But there have been enough times (maybe 2 or 3) where my lack of ABS (module went bad about a year ago and I just haven't fixed it...but its the next thing on my list) caused me to lose control in the wet during a panic braking situation (eg someone cut me off and slammed on their brakes). I never hit anyone or anything but sliding downhill in the wet with your brakes locked up is a shitty situation to be in.

My advice? Get the ABS fixed and keep it. Racing teams even know that ABS is better than no ABS (even if you can in some conditions outstop it). The reason most race cars don't have it is because its banned in the rules, not because they perform better without it.

I agree and wonder why some people wants to go the unsafe way, it's not only about their safety but for the others too..

Just did this yesterday (was a deer on a flat road, though). Luckily was no traffic at all, and wasn't too close of a call. But still...Scary.
Somebody cut me off on the highway the other day, too. Locked up the tires at 75mph!

Need to fix the stupid ABS soon. Also, the ESP is a really handy feature in the snow.

Do pre-facelift B5's(96-98, with or without quattro) have ESP? I know there is no physical button in pre-facelift..

No, and I *believe* even early 2001's don't have it either. As far as I know my car doesn't have it.

I believe thats correct, 01s only. I know my brothers 2000 doesn't have it.

[BaseDrifter]

Totally agree with the two posts above. This is not a race car, you're not a race car driver. This is a street car. Fix the ABS and be done.

^This. I recently nailed the trailer hitch of a 2500HD while locked up sliding down a hill in the wet. Such a helpless feeling. Makes me sick to think if I would have spent the money to repair the module that my car wouldn't be sitting in the body shop yard like it has for the past 3 months, not knowing if it's going to be fixed or not.

[AudiSport12]

ABS is not for the lazy. You're going to find that
idiot that pulls out in front of you and be pissed that you dont have it. You're an idiot to think that in a streetable car.
Oh, and here is what happened when I had the same mindset as you..

[ccollick13]

the first car i learned to drive was a non abs, with no power steering manual jeep and i never had one problem on the road. start learning to drive when i was 12. I'm 19 now and have probably only locked my brakes a total of 15 to 20 times and they were all on a track when i was first learning and I'm not trying sound like I'm perfect or anything. i just believe that you can drive just as safe without abs as you can with you just have to learn. with me saying that there are situation where even abs won't be able to help you stop in time.

Oh to be 19 again…

No one is doubting your ability to not lock up the brakes on the track. You're driving in a familiar manner, entering corners that don't change, on a controlled road surface, without other vehicles or objects suddenly appearing and attempting to collide with you. How many wet track days do you have under your belt in this car? I'm going to guess none.

Most people do not have a ton of experience panic braking in real life situations. Threshold braking is not easy in those situations no matter how much experience you have at the track, much less in adverse weather conditions, or in a car you don't track regularly. When you need to stand on the brake pedal because something or someone jumped in front of your car while you're going 80mph, you'll want the ABS.

But you're free to do what you want, and you sound like you've made up your mind. I hope you never have to learn the hard way like AudiSport did.

The first car in which I learned driving(by myself) didn't even have an ecu, the only electrically operated parts were wipers, horn and lights as far as I remember. Lolz.
I have loads of experience driving it in super busy streets from those days, but even then when somebody jumps in front of my car going at 50mph I will still hit brake like anything. You are getting 1-2 seconds of time to put all your experience into action, but I don't think human reflexes are that good...otherwise Kevin Ward would have been alive now..

[ray4624]

all points aside it would just be so much easier to spend the 50 dollars or whatever to have k0mpresd fix your module then delete it. Regardless if you can drive without it, the easier option is to simply have the module rebuilt. You being from orlando/baltimore get way less ice then myself and my only times having abs kick in were on ice so i dont see an issue with the delete. I just think you should put the effort into other aspects of modding the car lol

[ccollick13]

when i go with a big brake kit(which will be soon) non abs will give me more adjust ability with brake bias . i want to put a 4 port master cylinder with a balance bar and a proportioning valve in. so can anyone help me out with what master cylinder i should use
