Brake pedal goes all the way to the floor. Had the master cylinder replaced twice(thought the first one may have been faulty). Somehow air is getting in left front caliper, had that replaced, still pedal goes all the way to the floor. I am told could be abs module,or faulty caliper. They suggest I replace caliper first and if that doesn't fix the problem, then do the abs module. I do not wish to pay for both procedures is there any way to narrow it down to either problem without doing a repair once already done? ant suggestions? I have a 2001 Dodge Grand Caravan Sport all-wheel drive.
Im going to assume that a mechanic has already checked for the most simple causes like making sure the brakes have been bled. If the abs module is faulty it will default to just a no abs state, but that wont cause the pedal to go all the way to the floor. I agree that replacing the caliper is probably gonna fix the problem, but I might try to bleed the brakes first and see if that solves it first...
Ok well Im still gonna stick to my guns and say its the caliper... Is the caliper leaking, and what makes you think for sure its the left front? You are getting air into the lines somehow, and that means there has to be a leak... Thats what you need to set your sites on now...
To be 100% sure I wasnt going crazy, I checked with a colleague mechanic of 26 years. He agrees with me that for you to get the problem your getting then air has to be getting in the lines... The ABS module has no lines that have hydralic fluid going through them, hence how can there be air getting into the lines from it? Please have your mechanic order another caliper, and replace the old one, if that caliper is as new as you say it is, it should be able to be warrantied. If the problem comes back again, id tart looking for another leak before replacing the ABS module... This is way to good to not have you keep me updated now, even if It turns out Im WRONG I really wanna know it....
Hi
I had the same problem and my mechanic consulted with his other expert resources and advises that this is a common problem where the abs module bleeds air out of the lines when activated. The left side front is always the one that needs the bleed.
When my mechanic called and began to describe the problem, the experts first comment was "always bleeding the left front, we know the problem well".
The fix is to actuate/engage the abs while bleeding. Of course, if you don't have the tool to do so, the alternative (works well) is to drive, let pedal go down and keep bleeding until all of the air is gone.
You shouldn't need any more parts.
Sounds goofy, but that is the way it is.
I hope this helps.
I'm going through this same issue right now on my 2001 grand caravan. Going in to Chrysler dealer tommorrow morning to have brakes bled with scan tool hooked up. Will let you know results.
Joe I have the same problem with my 2001. I have changed the left front caliper several months ago and am still bleeding the caliper. I do not have any any codes showing up. It is obvious that I am not the only one with this problem. I am wondering if this is an issue that should be presented to Transport Canada as when I spoke with my locale Dodge dealer they state there is no recall notice for this problem. I wonder if Dodge is trying to ignore it hopeing it will go away. Brakes are a safety issue and I know that the 94 dodge I had was owened by several others before me and dodge still had to come good for the ABS module.Maybe all of us with this problem should send letters to the authorities and this might help to solve the problem

I have a friend with an 02 crams caravan same issue its not the abs pump dont throw your money away the left front flex hose was his problem has internal collapse have some one pump the pedal and watch the movement in both front hoses if the left flexes excessively replace it i changed his and problem is gone. We were bleeding his every 2 days been over a week with no problems. Hard to believe its a hose with no leaking but it fixed his
I'm having almost the identical issue. Amp the brakes few months ago was doing the "same" kind of thing and was told to quickly pump the brakes thinking it was an master cylinder issue, and that resolved it, now happening again and replaced the master cylinder. No help, I feel it is an issue with the "modulator valve", which is hydraulic, not the "abs module" which is electrical. Are there any procedures to verify my theory?

I failed to mention in my earlier post that After the second mechanic removed the air from the caliper and flushed the lines, the brakes worked perfectly for a week and then went back to the way they were, right to the floor. Does this sound like an abs module problem or should I go ahead and do the caliper a second time.
All lines were checked for leaks, they flushed the system and ran some tests and discovered it was only the front left caliper getting air. Seeing how the front left caliper was changed just days before this, the mechanic is leaning heavy towards the abs module, but suggests I changed the caliper to be absolutely sure. My problem is I just had that caliper changed and do not wish to pay again for a procedure that was already done if not neccessary, is there any way to pinpoint this problem without having to do exploratory repairs? It's a win-win situation for the mechanic, however, if I changed the caliper and it is the abs module causing the problem I am out hundreds of dollars and stuck with hundreds more to do the abs module.
Hey d-pownall, Did you get this issue resolved and what resolved it? I have been having the same issue with my 1999 Grand voyager. Now my mechanic is also telling me about the ABS module but that's an expensive option which I'm not guranteed it will fix the issue.
