I have a 2000 Dakota 4WD, and one of the brass brake line union blocks is cracked. It leaks fluid and the truck is unsafe to drive. This is the part that has three brass blocks on a rail, bolted to the frame, behind the drivers front wheel.

Three lines come down from the master cylinder/ABS, each is attached to a block, then each line goes out the other side of it's block to a front wheel or the rear wheels (one block for each front wheel, one line/block that serves both rear wheels).

Dealer can't locate the part anywhere, I can't find one in a junkyard, part isn't available online anywhere (P/N 52009888AC). They were only on the 2000, and the part was specific to 4WD, maybe only for all wheel ABS, so I haven't seen it on any other trucks or Durangos I've looked at. I did find a similar block/rail on a Durango that has the one brass block I need, but they're pressed into the rail- I can't just unbolt that one and change it out. Just to be clear- the part I found has a rail different than the part I need so I can't use the whole thing.

Should I get the cracked block braised or soldered? Sounds risky- would that hold up to the pressure? Can I get somebody to press the good block I have onto the existing rail? Other than keep searching junk yards I'm not sure what to do.

What's the best online junk yard parts locator?

I'm ready to drive my dang truck again- this is about the only part of the brake system I haven't replaced yet except the stupid ABS.

Any advice would be appreciated.

Thanks,

I would say have it brazed as a temp fix be cautious driving till you get the correct replacement part or safer to let it sit till you find a part for it

For it to crack like that I would say it had a defect from day one and finally let go.

Can you post pictures of the needed part this may help us to help you get the part.

Thanks; I'll check those websites. Will post some pics tomorrow. There's got to be one out there.

 

yo, 98DAKAZ, looks like you had grooves worn in your steering knuckles, too. I have the same problem on my Dakota. I filled 'em in with JB Weld, but it only lasts for a while. I've had to clean, score and refill the gouges a couple times over the past couple years. How did you fix it? Obviously, I'm not a welder.

 

I used a file on the knuckle just enough to smooth the groves out I also think doing this restores the brakes back to a nice smooth surface again so the pads slide better.

Just don’t overdo it.
