A few weeks ago I was backing out of my driveway when I noticed that my break pedal gave very little resistence when I pressed it and the breaks were very "weak".
I managed to stop the car by pressing the pedal very hard and then I pumped the break pedal a few times which seemed to restore my breaking ability. My ABS lights came on at the same time and then went back out.
Now, my breaks seem to be ok I guess but everytime I barely touch the break pedal an alarm sounds from the hood of the car. It sounds like 3-4 fast consecutive chirps.
The alarm sounds like it's coming from my ABS pump.
I think I noticed 1 more symptom as well, but I am not 100% sure. My break pedal feels like it can extend a lot further than it used to before this happened. I think I remember feeling a hard stopping point when I mashed the pedal and now I can go down as low as I want to and nothing stops the pedal.
Any ideas guys? My mechanic suggested replacing the entire ABS pump since the alarm was coming from that direction but I found out that that's gonna cost me about $1200 for a new one.
Background Information:
1. I drive back and forth on a road that coal trucks frequent and coal dust is everywhere.
2. I believe it was raining the day I parked my car in the garage.
3. I just had my brake pads replaced.
Car Information:
2002 Mitsubish Montero Limited Edition 4WD
EIther the ABS pump is bad and will have to be repaired by the dealer or specialy licensed ABS mechanic, or you can do what I do and pull the ABS fuse under hood and not use them.
Testimonial: "Prompt and helpful responses!"
pads may be new and not much pedal travel, I do suggest trying to bleed the system again. Also, the ABS has sensor on each wheel. The sensors do get dirty and tend to need cleaning. You can use electronical cleaner spray to do this.
Any mechanic can actually replace the pump. Which is what should be done. Unless you are like me and CAN NOT STAND ABS
I pull the abs fuse under hood on all my vehicles.
first thing I would do is find the ABS sensor on the wheels, remove each one seperately and clean them with electronical cleaner or equivelant.

Even though the recall was back in 2001 a dealership fixed it years later? Was there a cost associated with the repair?

Thanks so much for the prompt reply. I have a couple of followup questions please:
1. My mechanic suggested looking for a used pump and him installing it. (He is not the dealer nor a speciality ABS mechanic) You think that's a bad idea?
2. Are my "normal" brakes just as reliable with the ABS pump fuse pulled out? Will that basically disable the ABS brakes and leave everything else intact?
3. Should I still have the speed sensors or the controlled checked? I don't believe he checked those yet.
4. Is it worth paying a $100 just to have the dealer confirm that it's an ABS pump issue?
Thanks again for yall's help.
I removed the 10A ABS fuse and the chirping noise still goes off every time I use the brake pedal. Could that mean that I don't have an ABS problem? I would have thought that the removing the fuse would have completely disabled the system.

I have a 2001 mits. Montero in Costa Rica with the same problem. The Local "Rober-Dealer" quoted me a price of $4,000 to repair it. is there some way to bypass the ABS System and drive without it?if you have ant ideas. Thanks
Follow up to my previous post: I called the 1-800 number (you will need your VIN # when you do this) but in my case the factory call back repair had already been done and they would not honor it again. Apperently the dealer put the old part in which he probably had in stock and was already paid for instead of the new improved part.
It's likely the hudrolic brake booster. There is a recall/service bulletin and a warranty extension depending on year, in service date, and mileage. Go to a Mitsubishi dealer prior to getting it fixed else where. I had to jump through some serious hoops to get mine re-imbursed, but they will pay for it if your Montero meet the criteria and is under 150,000 miles. To check, open the hood, find the cylinder looking thing in front of the driver, start the truck, have someone press and release the brake pedal. Sometimes you have to pump, but you should be able to hear and feel the "chip". There's a rotor inside there that isn't working properly to build boost for your brakes. I've owned 3 Montero's (2002, 2003, 2006) and it's been the issue on 2 of them....
