    brakes on the truck pull sometimes, in either direction and it is not due to the grade in the road. they generally pull to the right the hardest as you are slowing down, from about 10mph and less, if you want to take a HARD right take your hands off the wheel. i've put on new calipers, new brake lines and new wheel cylinders in the back. not being a brake expert thought i would get some ideas. i know i need new ball joints and the steering box needs help to, could that be anything to do w/it?

    I see you have almost new everything, but did you purge the old fluid and start with fresh brake fluid and give it a "GOOD" bleeding? Try that first! /forums/images/graemlins/wink.gif

    Try resurfacing your front rotors, or just get new rotors. Make sure the pads have not been contaminated with grease/oil. /forums/images/graemlins/burb.gif

    Check the rotors carefully. Not sure what were on mine (second hand axles) but upon close inspection (because of a pulling issue) I noticed that there were "bumps" on the rotor, caused by something being baked on. Some sandpaper and I was back in business, no pulling.

    Make sure your calipers both slide freely on the bolts. Also check the front end out: wheel bearings, ball joints, tie rod ends, etc. If the whole front end is tight, chances are that the problem is either air in the lines or something wrong with one of the caliper setups.

    I totally agree with the other guy... bleed out your entire system!!! That is the best way to start.. and the cheapest... and most likely the problem... /forums/images/graemlins/deal.gif

    People are suggesting to bleed your brakes. I'm assuming you've already done this after your previous replacements, (so you got lucky ; ) but it's almost a given that bleeding the brakes "conventionally", results in the master cylinder failing.

    Not to say its your problem, just something to keep an eye out for when bleeding an old one.
