2005 Grand Caravan wheel smoking
I finally got me another vehicle and now the rear driver side tire is smoking. Jacked it up and there is no play in the tire so wheel bearing should be good. spins freely but with a rubbing sound. but the caliper grips when the break is pressed and the pads look thick. Any Ideas? also when I was taking the tire off the lug nuts were waaaaaay tooooo tight.

RE: 2005 Grand Caravan wheel smoking
First question is what was smoking? At the risk of making bad jokes, I doubt it was the wheel.... and since this is front drive, I doubt it was the tire. That leaves the pads / rotors (sticky caliper?) or the parking brake shoes. Some (minor) rubbing sound is normal from disc brakes and you should be able to turn thing by hand. Even the parking brake may make some sounds because of rust or minor shoe dragging, but still easily turned by hand.

Since this will require tire / wheel removal, I would raise the wheels and ask a helper to apply the foot brake then check each side to see if the caliper releases right away, or does it drag? If that seems ok then pull the wheels and inspect the parking brake cables for both damage or just being sticky dues to age. IOW, not releasing after the last application? Apply the parking brake again, then release and check for excess resistance.

At 12 (+) years old there's likely something going on due to age so you'll have to inspect everything and let us know what you find.

It's the parking brake. Any tips on getting the hub off so I can replace them?

Also would be safe just to remove the pads in general? I dont really use a parking brake.

RE: 2005 Grand Caravan wheel smoking
I dislike them even being called a "Parking" brake. They are an "Emergency" brake. If the hydraulic system fails they are there to stop you in emergency. If they are used every time you park, it keeps everything freed up and working properly so you don't have the sticking problem that you are experiencing. That's probably why they are called a parking brake. Here in PA we have "State Inspections" for autos. If the emergency brake doesn't work the car isn't allowed on the road. But even without a state inspection, I do NOT recommend disabling the emergency brake. I recommend repairing it and USING it every time you park. I have personal experience with the emergency brake saving people from disaster when the regular brakes failed.

As to getting the hub off...I need to know what the issue is? I don't remember exactly how that system is designed.

RE: 2005 Grand Caravan wheel smoking
When you say the hub, I presume you mean the rear brake rotor so I'll also presume you already have the wheels and calipers off and the rotor is "stuck" via rust on the central portion. Make sure the parking brake is fully released at the dash and the pedal is in the full up position. Put some penetrating oil around the wheel studs and the center of the rotor, then apply a few sharp taps to the flat area of the rotor between the wheel studs with a 2 pound hammer. Use ear protection as it's louder than you think. If things break free then you are on your way, if not then look closer to see if there's a pair of threaded holes in that flat face. They are usually metric, say 8 or 10 mm. You place bolts in the holes till they bottom out (only a fraction of an inch) and they will push against the cast portion of the hub, forcing the rotor to pop free. Give each bolt a half turn alternating back and forth between the two till you see the gap forming and maybe adding a few hammer taps along the way. The hammering will (hopefully) break any additional rust and also jiggle the shoes free of the ridge as things move.

Things to keep an eye on:
As the rotor comes off you may find the shoes binding against the inside and slowing your progress.
Back off on the parking brake cable adjustment, making note of where it was for reassembly. Also notice if someone may have recently changed that adjustment and it's in the wrong place, which is what's causing the whole problem.
You may need to push the cable into it's sleeve because it's sticky, or even cut the cable because it's frozen.
You may need to remove the rotor with force then replace whatever breaks.
Hopefully the bolts you put into those threaded holes don't strip out in the process but keep turning them. The shoes are only a bit more than an inch wide so it shouldn't take much till you can sneak a peek around the back to see what's holding things.

BTW, you may ask about backing off on the shoe adjustment similar to conventional rear shoes. Let's just say this... the adjuster and the actuator are different and for some reason none of the OEM designers have thought about making this task easy. In most cases you can't get to them with the rotor in place, Chevy and Mopar are the worst, only because I have never done a Ford.

Good luck and keep us posted.

RE: 2005 Grand Caravan wheel smoking
You can get the shoes off without removing the bearing / hub assembly, but it's much easier to see what you are doing if the vehicle is higher. Yeah, I understand the limitations of working in your own garage so it is what it is. At least you have decent light wherever you are.

BTW, don't forget to double check the brake cables being free.... and inspect everything else while in there. A new hardware kit is cheap compared to the pain of opening this up again.

Ask the kid next door to give you a hand?

Seriously, many of these newer cars (figure of speech for us old guys) don't give you much room to work and there are times when you need 3 hands to get the job done. For brake shoes you can hold them in place using a bunch of rubber bands or even a series of hose clamps, just to keep things from moving while you get those pesky hold-down springs into position. I have even used a bungee cord at times. Don't forget the possibility of using duct tape... but pull it off well before the sticky stuff works into the shoes. IOW, don't leave it on over night. Hopefully these ideas will spark your imagination.

Oh, as a last resort take a beer break and get back to it when the frustration level goes down.

Ok, it's 2 days later and wondering if you've made progress or pushed the car off a cliff, used dynamite, set it on fire, sold it as is, etc?
