F350 BRAKES LOCKING UP

2000 Ford F-350

Brakes problem
2000 Ford F350 Two Wheel Drive Manual 120000 miles

4 yrs. Ago the front brakes locked up. They were cherry red, hot and literally smoking. This resulted in the installation of new rotors, new calipers, new brake pads, new brake hoses, all new brake fluid, new seals and repack the bearings, etc.
Than in March of 2008 I had brake problems again which resluted in 2 new brake rotors, all new brakes pads, repacking the hubs and new seals.
The first brake job was wround $1,000 and the second one was approx. $500.00.
At 151,000 miles (fall 2007) I had two new tires installed on the front and new two tires on the rear. I kept the best tires from the old tires and installed them on the rear inside of the dual wheels.
At 174,000 miles I purchased 2 more tires, installed them on the front and placed other two on the rear.
All total, the rear tires have about 23,000 miles; the front tires are brand new.
Just two weeks ago I was driving my truck and I noticed that the truck pulled to the left when braking and pulled to the right when driving. The front end wouldstart shaking so badly that I could hardly hang onto the wheel.
I went back to where I had the tires installed and had them check for balancing and a defective tire. Everything checked out. I drove about 20 miles and found the tires to be extremely hot and the rims would have blistered your hands! I took it to a mechanic and they told me that the caliper is frozen up on the right side, the pads are totally worn out and that they need to replace the rotors and brake lines and so forth.
So for the third time I have same thing ocurring again - this time only on the right front (although I expect it's just a matter of time before the left side fails as well). My quote is again, around $500.00 but only for the one side! This quote is for new rotor, calipers, repacking and so forth.
My question is this - before I spend good money after bad (Obviously as this is occuring again!) - What is causing this brake failure? What are the mechanics missing? Something is being missed or else this would not keep ocurring.
My truck is a F350 Heavy Duty with a diesel engine, manual transmission, crew cab, long bed and has about 174,000 miles. It is driven for pleasure (on week ends) and I do use it to pull my horse trailer. As you can see, I have only put 23,000 miles on the truck since March of 2007 therefore it would not be excessive mileage and/or wear.
Right now my turck is sitting until I can find out the cause. No one seems to have a single clue. HELP!

There is a problem with aftermarket pads and rotors with the f series. Apearently the Motorcraft pad composition often allieviates this.
Make sure the rear are working good and are fully adjusted.

BTW, Check the radius arm bushings.

I'm sorry but this still doesn not answer my question or explain why the it keeps reocurring.

My apologies, I'll try to be more descriptive.

In 2005 your complete brake job did not include a rear brake adjustment. I assume these are rear drum brakes not rear disc brakes. "Make sure the rear are working good and are fully adjusted". IF the rears are ajusted it will help to give a better braking ratio t6hat will place more of the braking load to the rear so that the front brakes will have to do less work. The more work the front brakes have to do and the rotors overheat (sometimes accompanied by a pulsating feeling when braking

the brake fluid may boil causing the caliper to engage and locking up.
I would be surprised if the calipers were new. More likley remanufactured. Typically they have a lifetime warranty on them. Before you can verify the cause, the parts obviously need to be replaced (use the motorcraft as I had mentioned).

BTW, what is the real current miliage? Can't be 120,000. Are the replacement calipers being lubed correct and with a good grease?

It wouldn't surprise me if they needed cleaning and lubing every 6000 miles in your case. Since the truck does a fair amount of setting, the odds are greater that the slides are more apt to corrode, the
Pads tend to not move back well, rotors tend to pit. Any of these can snowball into multiple part replacement.

I just replaced pads and rotors on truck that someone else did and they lasted 4 months because of poor installation.

A suspension problem such as the radius arm bushings for example may be weak and causing an abnormal movement affecting the caliper.

Any divoted type wear on the caliper bracket can cause the pad to become fixed and ineffective.

At what mileage were they done at in 2005?
How often were they looked at between those two miliages?
And then what mileage the next time?
