Ok guys I have a 96 ram 1500 4x4 when I hit my brakes hard my front right side grabs so bad it eats my pads and rotor.. So I have replaced the rotors pads calibers brake hoses the rubber ones also the master cylinder a number of times and I am still having the same problem any help would be great if you can help me out here only thing left for me to change is the combination valve also none of the lights are on no abs light and no brake light are on.

 

Since you have changed everything else, (and I am assuming that means BOTH sides......) time to have a look at the hard lines.

Do you have 2 or 4 wheel abs?

 

Yes have replaced everything on both sides including the headlines. It has 2 wheel abs

 

That's just weird. Combination valve *shouldn't* matter, as it just breaks it up between front and rear circuits.......

Does the right side release properly? Does the passenger side get good pressure?

 

Yes very weird lol been dealing with this for a few years now has great pressure on the right side but it don't want to release right. At first I thought maybe it was the rubber line on that side collapsing on its self so I replaced it and still does it. Now when I put on new pads rotor and caliber it does OK for a very short time maybe a week or so then back to the samething

 

Are the brakes bled out well?

Not releasing is suspicious. New caliper/line/hose shouldn't do that. If it is repeatable after replacing the caliper, I would suspect the soft line. (yes, even if it is new...) How often has THAT been replaced?

 

Have replaced that line 3 times now I even took it to a shop and let them bleed the brakes thinking the samething.. Is it possible that for some reason I keep getting bad calibers?

 

That many in a row? If so, I think I would recommend you buy a lottery ticket.......

If you can just pump the brakes a couple time, and make the caliper lock up....... Think I would yank that wheel, pump up the brakes, crack the bleeder. If the brakes release, pump them up again, and crack the line where the hard line meets the soft line. (up on the frame) and see if it breaks loose..... and just keep working my way back toward the M/C, see where it STOPS releasing the pressure, and you found your suspect component.

Calipers rarely fail.... I have replaced them due to other problems though.... (seized bleeder valves, messed up mounts or guides, etc.) But I think I can count the number of 'seized piston' replacements on one hand. (and I have been doing this a LONG time..... )

 

Lol I have to replace the pads and rotor again this week so I'll start from the tire and work my way back to the master. Thank you for all the help will let us now how it goes.

 

Definitely let us know what you find. I am real curious on this one......
