1999 D had front R brake lock up in July. Replaced all parts including hoses.
D has 119000 miles and about 6K since last summers brake issues.
Went for a short trip about 7 miles total and noted it felt tight.
When I got home smell burning and wisp of smoke from R front wheel well.
The wheel was HOT compared to L side which was just warm.
What should I do this time. Seems ridiculous to replace everything all over again if the problem may continue to pop up. Do not want this to happen when out of state of with it full of family on a trip.
Why is this happening again.
Frustrated D owner.

is this a vehicle that you dont drive much? believe it or not but sitting long enough without use can cause rust to build up on the rail where the pads slide, making it so that they dont slide smoothly, this will make them hang up when you let off the brakes and drag (hence heating up that wheel)
-Phillip's Law: Four-wheel-drive just means getting stuck in more inaccessible places.
if its not the caliber or the caliber pins....i would have to guess one of those valves by the brake booster, becuz its only happening to one tire. never seen those valves break though. i would first make sure that front caliber is moving freely and that the pins are well greased.
it sounds like its the caliper but you said you replaced all the brake parts... have you tried re-compressing the caliper that was having issues? might have gotten a bum caliper... i had to do that... replaced both front calipers cause they both took a dump...

Water / contaminated brake fluid will cause caliper pistons to set up as well. You may want to consider purging the brake fluid and replacing it. Just make sure that you don't allow any air bubbles to enter the system if you have ABS as it'll require dealer intervention to reset the codes.
Rotors NOT rusty.
One bolt was tight in the boot.
Cleaned and greased.
Maybe should LOAD up on the grease.
It was moving freely when I put it back.
How do I check for a stuck piston?
It moved in when I compressed it with my C clamp.
Glad you found the problem. Regarding a stuck piston, they should compress relatively easily and smoothly with a C-clamp and an (old) brake pad in place as a spacer. Remove the cap from your reservoir as well. A close physical inspection of the piston for cracks corrosion as well as looking at the rubber boot is about the best you can do without dissassembling it.
If the boot is damaged or there is any signs of fluid leakage at all, replace / rebuild the caliper.... period! Brakes aren't anything to mess around with, they need to be done right every time. I clean all of the parts with brake cleaner and then grease all of the contact points with synthetic brake lube. A small wire brush is also handy for knocking off the scale.
Something that I just found recently was a slight leak in one of my rear calipers. I picked up a rebuilt at AutoZone and was surprised that it came with the caliper as well as the whole mounting bracket assembly. I've never seen one come like that before, sure was nice putting in all new clean parts!
Were talking about the knuckle.
No listed at RockAuto. Will cont to look else where.
Do I need to replace the Knucle? If the pits are hanging up the pad sounds like it
Any it only occurs and locks up on the left side. 2nd time now.
In the mean time I'm goin to gently and carefully grind on edge of the knuckle where the PITS are to smooth it out and grease like hell.
Not sure what to tell you about replacing the knuckle, I guess it depends on how bad it is? The bracket I was talking about was for an '03 and it was the rear disc's, but I *thought* there was a similar caliper bracket on the fronts as well? It's been awhile since I looked at the front brakes so I may be mistaken.
I also seem to remember some stainless steel pads that clip in place that the pads slide on. I know that they're like that in the rears. Again, it could be an '03 brake thing.
DrewsDurango98 : You would think that it should affect all wheels, but I can tell you that I chased this on my Mustang for quite awhile with one caliper hanging routinely, even after replacing it twice. Finally replaced all of the fluid and the problem went way.
I took a sanding pad on my cordless drill and cleaned it up some more.
A few different hand files to bevel the divots on the pad slides.
New slider bolts and lots of grease.
Hope I'm done here or it's new knuckles for this D.
