I have a 99 2500 4x4. I had this problem when I first got the truck put a new trac bar on. Still Pulled hard to the left when I go to brake. Put a new Hydro boost on cause the other one was leaking still pulls to the left when I go to brake. Put new calipers and pads on. It stoped pulling to the left for about 2,000 Miles. So it started agian about 3 days ago you could barely notice it. Now today when you hit the brakes you have to steer to the right and the wheel is about a quarted to half turn to the right when I come to a stop. Does anyone have any Idea what is goin on with this truck any help would shure make my life alot safer and others around me thanks.

 

A brake issue could be caused by a flex brake line that doesn't sound like you have changed.
Now comes the suspension issues: Alignment, tires, wheel offset different, and have you raised vehicle?

 

I have a leveling kit on it but it was on since the truck was 3 months old. Front was aligned about a month or so ago. What I am not getting is why when I put new pads and calipers on it stops pulling. Like this morning on the way to work I hit the brakes and it still pulls but as the day goes by my truck runs all day and I get back on the highway it will pull so hard to the left I have to steer to the right to get the truck to stop strait.

 

Drum rears? If so check right rear, it may not be working and needs adjusted or the left rear is too tight. Could also be a stuck caliber on the left front, even with only 2k on the new ones.

 

You may want to try and bleed the system. When you replaced the calipers did you flush all the old fluid out? I can also second on the flex lines, it doesn't take much to loose pressure. You may even want to look at the proportioning valve, maybe your loosing line pressure in there...I've never had that be an issue just another place to look into?

 

The most common cause of this is actually the pads. Usually they will start doing this after being overheated, but occasionally a brand new set will do this. To diagnose, swap your pads around from the left side to the right side, and drive it to see if the pull goes the other way.

 

also verify tire pressure, its usually the last thing people check, one tire low will cause it to pull to the low side

 

Ditto, check/replace the brake lines, probably the right side. Sometimes a brake hose will collapse on the inside, not allowing fluid to get through it. If it is pulling to the left, that means the right caliper would be sticking (the left is doing all the work, thus making it pull to the left), when a caliper sticks, it doesn't usually stick in the ON or braking position. Since he recently replaced the calipers, I'm guessin that's not the problem, although, I have seen new calipers be bad right out of the box.
Overheated brake pads will not "stick". When they get hot and then are allowed to cool, they glaze over and and become hard and will not provide any stopping force. I'm not sure if that's what you were implying, so if not, then please disregard.
I'm guessin it's the right front rubber brake line, but that's just my opinion.
Let us know what you figure out.

 

I am goin to go ahead and replace the lines and see what happens. It that doesnt work I am tired of messing with it. Plus I just found another leak on the hydroboost where the two high pressure lines come off, one is soaking wet with brake fluid, so I will replace it and bleed the whole system agian. I am fixing to just take it to the dealer and let them rape me so they can pay the highscool kids to do the work on my truck. I am just tired of messing with it. Working seven days a week. 07 or 08 sticker price isnt looking to bad HA.

 

AHH yes that what I meant. Had the rears on my brain and thats what the hands typed.

 

The 94 to 99 Ram trucks have been notorious for brake pulls. The linings can easily become overheated, which changes the friction characteristics of the lining material. This has, in my experience, become the leading cause of brake pulls on these trucks (although there ARE definitely other causes). In my opinion it would be a waste of time and money to throw brake hoses at it without simply swapping pads side-to-side first for a test drive. While technically it is certainly possible for a brake hose to swell and rupture internally and cause a brake pull, in my 20 years as a licensed technician I have never seen it, unless the brake hydraulic system had been contaminated with an improper fluid.

 

A 20 YR. LICENSED TECHNICIAN OH MY, I guess that means that I'm wrong.
Good luck cm979 gettin ur truck fixed.

 

Whatever, throw some parts at it.

 

I guess I should have stated my last post differently, I don't mean that I'm right, just stating my opinion like everyone else. I was not trying to prove you wrong or say that ur wrong, just stating my opinion as is allowed on a public forum. You chose to make a production out of it.
I am done now cause this is not helping the original poster get his problem fixed.

 

Sorry Hink, I didn't mean to imply you were wrong. I just meant to try something that's easy and free first.
