Well I have been working on vehicles for a few decades, and I have never seen a vehicle loose brakes after the ABS light lit!

So can you tell me when you have seen this issue before, tell me the vehicle and the problem?

I have driven many vehicle with the ABS light lit and the only thing that has happened is the the ABS brake system activated and the vehicle took longer to stop due to the brake system pulsing.

And you have no idea what the issue is here do you - nor do I. So really all your doing is making a bunch of noise about details no one has yet. Heck for all we know a brake cylinder has failed in a spectacular way and history shows Uncle Ed fixed some issue with the brakes 3yrs prior but nothing was ever said about this. If you think Subaru brake systems are special and any different than Honda or for that matter all the other makers LOL - - Subaru isn't that special.

Yes he lost his brakes after having Rack replaced.

Also I never said Subaru ABS system was special, All I said that if the valve caused loosing of the brakes that it needs to be looked into! Because that shouldn't cause lose of brakes(if this valve is in the ABS system and had a failure).

OP sorry for ruining your thread!

plus there's a Err 55 message that reads where my trip odometer reads....what could this be?
Here's some info on error codes in the odometer screen:
http://www.scoobymods.com/showthread.php/error-codes-odo-display-6511.html

they have to do with communication issues - yours is for "wheel speed data malfunction" so maybe the tech damaged one of the leads to an ABS sensor - that in and of itself shouldn't cause a loss of your brakes, but maybe they damaged the brake line, or let air into the system, which is allowing the pedal to go to the floor...

My pedal kept going to the floor once my abs light went on...it was scary but I was a mile from my house, but before my car was serviced my brakes were fine
And then again here:

I haven't tried it yet....I've had my abs light come on before and ive shut the car off and turned it back on and the light has gone off and I didn't have any problems
Okay, ABS system learning time. Your arguments are fruitless and without merit.

This is not air brakes. The ABS system works in conjunction with the hydraulic system on any car. It relies on hydraulic pressure to operate. With 4 WABS, each wheel has a speed sensor that communicates the wheel's rotation to the ABS module. When the modules "sees" a wheel moving slower or at a stop in relation to the other wheels and the operator is applying the brakes, it will activate a control solenoid and dump valve to pulsate the pressure to the wheel losing traction to maintain a rolling state rather than lock up.

Sensors on the hydraulic system in more recent builds communicate hydraulic pressure, pedal pressure and reservoir fluid levels to effectively operate the complete system.

If the hydraulic system has a failure, then the ABS cannot function. If the ABS module, motor, solenoids or speed sensors have a malfunction and it is seen by the ABS module, the ABS is deactivated and stopping relies solely on the driver's attention to loss of traction.

In the scenario we have here, there was an issue with the ABS prior to the visit for the steering repair, but it was ignored. We can assume, based on the OP's description, that it was an electronic issue since it reset with the key off, then on. We don't know what the issue was because codes and history codes have not been posted. We don't know how long its been since the initial incidents to now, so there is also the possibility that any history codes have cleared themselves. Also, if the dealer tech disconnected the battery while doing the repair, memory is wiped clean up to that point. Prior incident codes are mute.

When the ABS light comes on steady, there are two things that clear the light and reactivate the ABS. One is repair of the fault. The other is a key cycle where the light will go off after a bulb check and stay off until it sees a problem emerge.

When the system detects and issue with the hydraulic system, it deactivates because it needs the hydraulics to perform in order for the ABS module to perform.

As for the drop in pedal and then the ABS light coming on; duh, hydraulic issue with the vehicle caused the ABS to disengage and deactivate because it knew it would be worthless to operate without a proper operating hydraulic system.

There is apparently, now at this time, an issue with the hydraulic system. It could be in the master cylinder. Could be in the ABS motor assembly. Could be something at the wheels like a hose leaking, a bleeder valve is open, a joint at a connection is leaking, a caliper seal is leaking or a dump valve within the ABS unit or the relief valve in the master cylinder is stuck open allowing for loss of pressure. We don't know.

As for the vehicle not stopping. Apparently it did, just not up to full snuff. So somewhere on the car brakes did apply to slow and stop the car. FAILSAFE.

Stop with trying to lay blame on the manufacturer. Your just spinning your wheels.

Thank you everyone for all your input...I took the car back to the dealer this morning, I still have my ABS light on and my ABS doesn't work...the car just skids when I slam on the brakes and we are supposed to get snow tomorrow in NY too ha oh well....I've driven my dad's 1976 Bmw 2002 and that doesn't have any safety features to it at all and no ABS so I know what it's like to drive a car that just skids...anyway the dealer told me that one of my ABS sensor is malfunctioning which is why my ABS light is on and the Err SS message is displayed where my trip odometer is...and he also said this would be why my brake pedal was going to the floor...but something doesn't seem right to me...because why would my car go into the dealer and come back with this problem...A few years ago my mom's car went to the dealer for routine service and once we got the car back things started breaking left and right....Drive shafts, axles, 4WD binding, steering rack started leaking....Anyway I have been to this dealer many times before and they have been helpful in the past but I still am curious if they may have done something ...I dunno

I should mention...Before any of this happened....I took my car in to the dealer because I noticed my steering rack was leaking and the dealer put on my snow tires....I picked up my car last night and noticed the brake pedal was mushy but didn't think much of it until my ABS light came on and went to the floor....Now the dealer ordered the ABS sensor for my car and said my car was safe to drive and my brakes are as hard as a rock now...but Yes my ABS light was on and my pedal went all the way to the floor and I know that there was something seriously wrong

Yeah, that's what I figured....honestly it's a load of rubbish that I've had to take my car there 3 times in the past week....I shouldn't complain the brakes are the most important part of a vehicle
