I recently had my brake pads and rotors replaced on all four wheels and when I got my car back I noticed that about every other time or so I start my car my ABS sensor would pop on in the dash. In the past I had a ABS sensor replaced, but never had a problem again until this recent brake job. Not too sure what the problem is but probably just need a new ABS sensor. Does anyone have any recommendations of what this problem could be caused by? Its really weird because some of the time the ABS light will go on after i've recently ran my car and start it back up, but other times it won't do this. It just doesn't make sense i'm guessing the mechanic that did my brakes might have touched something causing this problem. I have a 94 integra LS and i've seen similar problems for integra's with ABS system brakes. Thanks to everyone for the help in advance and hope you know what this could be caused by.

 

I'm guessing the mechanic might have touched something. How long ago was it that you had it changed?

 

yeah thats what i'm thinking too. it was about 2 and a half months ago or so, ever since then i've had this problem.

 

Does the ABS kick on out of no where? That would be a sign of a failure to a sensor or reluctor ring. The ABS light goes on at startup for a few seconds for a self check if thats what you're experiencing.

 

no, it'll come on when i start the car up and stay on until i shut it off. but this is randomly, it's not every startup that it does this, which is strange. yeah it doesn't just stay on for a few seconds, its on for the whole ride and sometimes the next few too. i know what your talking about though i see the ABS light come on at startup and then shut off, but this is different.

 

I had a similar problem on a 2000 G-SR sedan, my ABS light began coming on randomly, immediately after I changed the brake pads myself.

I figured I messed something up permanently... BUT when I changed my brakes the next time, I discovered that one of the metal backing plates which slide behind the brake pad during installation had slipped out of its correct spot (presumably during my installation).

When I put the new pads on i took special care to watch these backing plates, and a short time after the installation (not immediately) the ABS light went out for good.

DOnt know for sure that this was the problem... but it was an extremely suspicious circumstance.

 

It sounds about right, my brakes are squeaky (which is common) but they've been squeakin for a while now, almost as long as when the brake job was done.

I hope this is part of the problem with the ABS, even though they can squeak at anytime. Will the backing plates be a reason for the squeaking?

I think he might of touched something and didn't put it back right, especially with the ABS sensors they can be sensitive.

 

If your brakes are designed like mine, and have these shims/heat shields, they could be the squeaking culprit for 2 reasons.

1) I *think* the squeaking mechanism (that indicates when to change pads) is located on this shim... but i cannot imagine the shim contacting the rotor just by being improperly installed.

2) Second, and probably most likely, I just remembered that the brake pad of mine (which had the improperly installed shim) had very uneven wear since the shim didn't allow the brake pad to fully seat in its slots. It was like a 10 degree angle from the front side of the pad to the rear. I could see this causing some noise.

I hope your problem is this simple...

P.S. I had a front end collision on slick roads during the time when my ABS light was on, and nearly got arrested over it... and I blame the brakes. I would suggest looking at them asap.

 

Yeah i'm just going to get a diagnosis done on it to see what the problem is. Hopefully the scan will indicate what is causing the ABS light to come on almost every time I start my car up. This is really getting annoying and I hope theres nothing majorly wrong with it.

 

Ok I ended up getting is checked and the mechanic said its putting out a code 18 which has to do with the abs system. However, I'm not sure where to get it fixed at without going to the dealer and paying a fortune. Do you guys know where I could go for this in Connecticut?
