Help me please woman owner of 99 dodge cummins 24 valve 4x4 emergency brake light and abs keep cumn

[Kassidygee]

Please help! The emergency brake light and ABS light keep coming on and turn off regularly. A few months ago I Reflashed the ECM Re- did the brakes and replaced a sensor because I was loosing braking power and they would lock up on me. All was good for a month, no lights coming on. Then the emergency brake light and abs started coming on and off all the time. I noticed a decrease in breaking power over the last week.

Also another issue; about 15 times my truck acted like it was in neutral, when it was in drive, (in the first 4 minutes of driving it.) This happend once in reverse when leaving for work. Torque converter? Transmission? Hmm I just dont know. I could really use some help. Your time is appriciated! Thanks so much!

I'd help you even if you were a male owner...

Does your truck have 4 wheel ABS or rear wheel only?

I think rear.

 

[Kassidygee]

What do you own? Do you do the work yourself on yours?

I think rear.

4 wheel ABS has sensor wires on the front axle housing which run out to each front wheel hub. They are visible... The rear wheel ABS only has the rear sensor which the 4 wheel ABS has too.

If you do not have 4 wheel ABS and yet you lost all braking power then its not related to the ABS system.

What do you own? Do you do the work yourself on yours?

I have an '01 and I do most all mechanic work myself. Not everyone has the ability or the tools so I understand...

Te 99s were first year to come standard equipped with 4W anti lock brakes.

 

[Kassidygee]

We do the work ourselves too. What a headache this has been though. What do you think it could be?

 

[Kassidygee]

So i must have 4 then...

No, it was an option all through the 2nd gen years.

 

[Kassidygee]

Oh ok

 

[Kassidygee]

Sorry i thought you said they come standard with 4 wheel abs.

 

[KATOOM]

No, they come standard with rear wheel ABS. 4 wheel ABS was an option. And depending on what ABS system you have, the problem could be the hydroboost/accumulator, the hydraulic pump, old nasty power steering fluid, failing master cylinder, collapsing brake lines, etc... So understanding exactly what you were experiencing and what you did will help.

 

[Kassidygee]

I found out I just have 2 wheel abs

 

[KATOOM]

Then you can rule out the ABS system. I'm guessing since the ABS/Brake light is coming on that your master cylinder is bad. What exactly happened? That will help narrow it down.

I experience loss of braking power they would lock up on me when id brake and jerk the truck id let off the brake and have to press it again to come to a full stop.
Replaced the rear differential sensor brakes fluids are good. And reflashed ecm.

Everything was good for a month now its doing it again.

 

[KATOOM]

Why did you reflash the ECM? Was this someones suggestion?

The ecm was my truck not starting once we did the ecm it started ..i had multiple issues going on. Similar time frame.

 

[Kassidygee]

So disregard that, just did all of the work iaround the same time so I included it.
