BREAK DRUMS; rear passenger HOT!
Hey all! Could really use some advice as I, and others are getting no where with this problem. So, I decided to change ALL my breaks, rotors, shoes and hubs, cylinders, on my 2000 Cherokee Sport 4L in-line 6 a few weeks ago. Brand new everything. No problem right? After fighting with getting each lug nut, tire, hub, break lines and darn near everything off. After 3 separate weekends, I made it. Took it for a spin and wash, coming back up the river (55mph) I was smelling what I thought was someone burning tires. It was mine, but only the back passenger hub was ON FIRE when I got home. Cooled down, Next day lifted the jeep, spun tires.. they spun free, took it all back apart bought new spring set, thinking springs are old, causing the shoe to rub against the hub causing it to get hot. put back together, still getting hot. Called a friend. We replaced the breakline, cylinder (I mistaked by lifting it and removing the hub and having my girlfriend put it in neutral then applying the breaks, the pressure without the hub on caused the rubber end piece to fly off.. so it was ruined and bought another) . Put the hub on, it fits kinda snug, unlike the driver side, which has some play in it They are 9” shoes. It’s still getting hot. Now I’m outside with both tires off, lifted, spinning the hub. The driver side spins freely, the passenger side goes maybe 3/4 turn. It feels like it’s tight. Knocked them repeatedly and have the adjuster pin tuned all the way in. I’m hearing this is an issue with some people but it’s because the cylinder is froze and not releasing break fluid. My cylinders are brand new, master cylinder under the hood is full and not leaking anywhere. Does anyone out there have any suggestion as to WHY that one single back hub is repeatedly getting hot? I am literally out of juice dudes.. I’ve even had a mechanic come down to verify my work. He’s supposed to come back tomorrow but I thought I’d try here as well..
could it be the parking brake? I would disconnect the cable and see if the problem still occurs. Old cables are a problem. Bicyclists us a product called Dri Slide (also popular with gun owners) which is a Mb di sulfide lube that penetrates like crazy

i had this problem once. ended up being the rubber brake line going from the rear axle to the frame. can you get plenty for brake fluid out the rear cylinder when you try to bleed them? if so this may not be your problem
