I just recently busted a brake line the main one (in the middle of the truck) and after it happened I put new lines from the front of the main line long line to both sides of axle. Also put new wheel cylinders in both back wheels along with shoes, hardware kit, and new drums. After I bleed the lines real good the lights still stayed on so I replaced the speed sensor on the top of the rear axle and still same thing. If y’all have any suggestions I’m all ears I’m officially stumped thanks.
It’s a 1998 Dodge Ram 1500 5.9

 

I'm assuming that the brake line that burst is the rear brake line that runs along the frame near the fuel tank and feeds the rear brakes, correct? That brake line is famous for failing on these trucks, even back to the 1st gen Dodge trucks.

When you bled the lines, is the brake pedal good and hard? Also, does the brake pedal respond firmly when braking while driving the truck or does the pedal feel spongy? I take it that your truck only has rear ABS braking?

 

Yes it was the one that runs beside the fuel tank. I’m going to retry bleeding the brakes on all 4 wheels again I did realize my fluid level was real low by the the time I got it back home. I guess it’s a good possibility I still have some air in the lines. The pedal is firm but it does have a little softness when you press it all the way down. Let me know what you think. Yes it does only have abs on the rear.

 

Sounds like you still may have some air still trapped in the lines. Best to have a friend help pump up the brake pedal while another person opens the bleeder valve at the wheel, all while ensuring the pedal goes to the floor and the other person tightens the bleeder screw. Be sure to keep the master cylinder reservoir as full as possible while you're doing the bleeding process. Be sure to bleed the line farthest from the master cylinder 1st (passenger side rear) and work your way around (next driver's side rear, passenger side front, driver's side front). May have to do each wheel more than once to ensure you get all of the air out of the lines. Just FYI, I prefer to use DOT4 brake fluid as it has a higher boiling point than DOT3 fluid.

 

It set an ABS code, You need to clear it and you should be good. Disconnect the battery and let it sit overnight and hook it in the morning.

 

What exactly makes the light stay on? I service a '98 that we just can't get the damn light to go away. Rear shoes are thick, front pads are new, pedal feels great

 

Need to know why the PCM thinks the lite should be on......

 

It was air still in the lines had to almost bleed 8oz through to get a big air pocket out and the lights went out thanks for everything.

 

Awesome. Gotta love the inexpensive ones.
