I have a 98 4.6l F150. 2wd. Drum brakes on the rear. 2 wheel abs.

I inherited this truck. My dad bought it as a parts truck and swapped the body parts he wanted for his truck and gave me the donor truck. It runs really good and is all around a solid truck. But not long after I got it the brakes started grinding. I changed the pads and the old ones still had padding but were crumbling due to age. I put the new pads on and this is where the trouble started.

Since then I have had issues with the brakes sticking. I cleaned and lubed the guide pins when changing the pads and they seemed alright. I also don't think it is the calipers because both front are sticking. The rear could be too, but being drums I cant really tell. They seem to stick worse once they get warm. I thought maybe there was too much fluid in the reservoir so I removed some and it is dead in the center. On my way to work this morning they clamped tight and I limped it to my office (probably less than a mile). After work they were released and then no issues on the way home. I left and went on a 2 mile round trip and when I got back they were sticking (not as bad as this morning). The pedal has a lot of travel but I am not sure if it just seems that way to me because my daily is a 22 honda civic and a completely different ride all together.

Any idea of what could be causing this? I didn't know if maybe the Master Cylinder could be pushing the fluid out and restricting the flow back or if that is even a thing. Any help would be nice. Want to fix the truck up but have to get it safe to drive before I can do the fun stuff.

 

Old truck has old parts. The truck is telling you it's time for a update.
Start with NEW brake fluid....complete.
Get 4/5 cans of brake cleaner and clean everything so you can see. All new rear brake HARDWARE and new cylinders.
May very well have the factory OEM calipers. Get new ones.
Nothing last forever.

 

I did the brake fluid when I did the pads. The entire front has been cleaned. I replaced the wheel bearings as well. Haven't touched the rear (aside from bleeding them). The front brake calipers are most likely the original but seem to function when off the truck. Slide smoothly and compress easily. I am not opposed to changing them, but I am not big on just throwing parts at things. I would rather know what the actual issue is so that in the future or for other vehicles (that may have newer parts) I am not just throwing parts at it. I will go through that if that is what it comes to, but again, I would like to find the actual failing part.

Read post #7 in this thread.
Just a possibility it could be the hoses failing.

 

That describes my issue exactly. I will check that this weekend. If that solves the problem I will let you know. That is something I would never have thought to check. Thanks!!

 

When stuck when hot, loosen bleeder screw and if inside rubber lines are collapsed,
which they probably are, the pressure will be released and wheel can be turned.

 

I will also check this. Thanks.

 

I am with Magnetic5.0 's post #4 on checking the front brake hoses
The clamp that rusts squeezes the brake hose shut
Just take a big screwdriver and open up the clamp that holds the front brake lines is what I did on my 97
Do that to both sides and the front brakes will stop sticking
