Hey there! I just joined the forums today. I have a 2001 Dodge Ram 1500 5.9L 4x4 Sport Off-Road edition. I recently had to brake pretty hard due to some crazy in front of me. The ABS and Brake light now come on randomly during each drive. They do not come on as soon as I turn on the truck, however it seems to come on under certain conditions after braking. Sometimes they turn on when I first brake and sometimes it's several brakes later. I do not notice any difference when braking. Would anyone happen to know what it could possibly be? Thanks in advance!

 

2 or 4 wheel ABS?

 

It's a 2-wheel ABS. I actually figured out when it's causing the lights to turn on. It turns on as soon as I let go of the brake after pushing it all the way down.

 

That's likely air in the system, or a leak somewhere. The line running to the rear along the frame is notorious for rusting out.

 

I'll be sure to check it out. Thank you!
