Ford Super Duty (1999-2016) :: Parking Brake Not Working - Burning Axle Seal?
Jan 20, 2015
Will leaving the parking brake on burn up the axle seals? My parking brake isn't working well at the moment. I need new ones from all the fluid my bad seals leaked on them. So, at the moment they just scrub a bit while its engaged. However, today I found out that my parking brake light for one reason or another is not working and I got in a hurry and didn't release the brake. by the time I got to where I was headed (about 15 miles), I could smell gear fluid burning and my driver side rear was smoking. I'm hoping its the fluid that was already soaked into the shoes. I did find a drop of fluid on the bottom of my brake caliper.

I noticed the other day after my truck was parked on a bit of a angle there was diff oil from the passenger side on the ground. reading a bit on here i learned the axle seals are way in the front housing close to the front diff. and yesterday driving a heavy load around my front brake driver side got stuck on a bit and over heated and was smoking, couldn't even touch the rim it was so hot. anyway about this axle seal i got the hub off right now but cant seem to pull out the axle assembly through the knuckle but i see i have to pry and most likely wreck that seal. Looking for a link of piuctures or how to replace the axle seals in the housing.

99, F250, 4X4, V10, 72,000 miles. I have had the front axle seals replaced three times in the past 3000 miles, and the right continues to leak. My mechanic screwed up three times?

Replacing the knuckle/axle seal due to my hub not holding a vacuum. I finally got the seal off the axle after several minutes of beating, but it finally came off. During the beating the metal shield that was in back of the seal took a beating as well and can not be reused. Is it really needed?
In this thread the pictures show that the shield was not installed after the seal was replaced. The shield does serve a purpose to keep crap out of the seal though.

Do I need a special tool to put the outer axle seal on a 2003 excursion? I could make one if I new how far down it needs to be. I'm replacing the needle bearings in the back of the hubs and it looks like the last seals were not on far enough and the hub tore them up....

I was looking underneath the truck yesterday and saw that the rear end pinion seal was leaking. Looked like it had been for a while. Truck has 35,850 miles on it. Unscrewed the fill plug and a lot of pressure is released. So I'm assuming the breather is clogged somewhere along the line. I have an appointment at the dealer on Friday to see whats wrong. What is supposed to be at the end of the breather tube? Mine has a barbed 45ish degree fitting on the end of it. Its a SRW by the way.

The problem is I haven't seen one for a recent (2011+) SD. I don't see anything that resembles a rear drum. They look like 2 huge regular disc brakes.
I live on a hill. My old man taught me to put the trans in neutral, autos and manuals, put the ebrake on and make sure it holds the vehicle, then put the trans into park or 1st gear. This way the weight of the vehicle doesn't rest on the transmission.
How do I adjust the Ebrake? It's ALMOST holding the truck, just needs a minor tweak. I don't see the dust cover the write ups described at all. The one that reveals the Star Wheel. Are they different on these years then prior SD's?

The wife and I ventured out last Friday evening to run a few errands. When we returned to the house and pulled into the garage, we both smelled burning brake pad. I felt the rear wheels, the drivers side was too hot to touch.
Dragging brake caliper. I got online and reserved a drivers side caliper and a set of pads at NAPA. Saturday morning I removed the caliper. Much to my surprise, one of the caliper pistons was broken into multiple pieces.
I took the offending caliper to NAPA and picked up the new caliper and a set of pads.
Side note - NAPA seems to think the 2007 trucks have calipers that mount in front of the axle, not behind the axle. They will try to sell you a passenger side caliper and tell you it is a driver side caliper. It will bolt up fine, but the bleeder valve will be at the bottom of the caliper instead of the top. You'll never get the air out of the caliper.
Got back home, bolted up the new caliper and pads, then bled the system. All worked well.
I decided to throw new pads on the passenger side brakes as well, since I had 2 remaining. I took off the passenger side caliper, much to my surprise I found a cracked and broken piston on that side also! Another run to NAPA to pick up another caliper. Installed, bled the system again, all working well.
Now, I have never seen a cracked and broken caliper piston like this, let alone one on each side of the rear axle. What might have caused this? About a year ago I had a shop install new backing plates. The pads and calipers are about 3 years old, same shop installed those.

I know this has been talked about many times and how to solve the issue but thought I would ask some other questions too. Earlier in the summer, I did grease the slider pins as preventative maintenance. I don't drive my truck all that much and when I used it yesterday, (about 30 minute drive) I came home to burning brake smell. I'm wondering if enough heat would cause the caliper to go bad? Should I just grease the pins again or change out some parts?

The '99 F250 has the parking brake release under the dash, way down low. While I was in the wrecking yard, I noticed many Excursions and Econolines have them on the left, by the parking brake. Whether one of those might work, if I installed it on my '99?

How to replace the parking brake cable from the pedal down to the connector on the frame? We got a 2000 F350 in the shop with a bad cable, and i never did one. And I don't really want to mess this thing up trying to figure out how to change it.

When I parked my truck at work this morning, I pushed the parking brake pedal down like always, but it popped back up. I didn't pop all the way back up, it stayed down about 1/4 of the way. Several tries yielded the same results.
Since I'm at work, I didn't have any time to crawl under there are investigate. I'll do so tonight when I get home, or maybe tomorrow. Kinda sounds like the locking "teeth" mechanism may be misaligned?? Since it doesn't come all the way back up, I'm hoping the mechanism isn't totally broken.

80% of the time my parking sensors are always on, like something is behind the truck. 20% of the time they work just fine.
I replaced all 4 sensors today with ones off ebay and I get the same thing.
Anything else I can try before I have to take it to the dealer?
The originals and my new ones all clicked when I put my ear up to them.

I have a f250 super duty. I blew a brake line the main going to the rear. So the genius that I am I replaced the line an simple enough I decide hell why not replace the master cylinder too, so I did an I bleed the brakes an everything works jst fine but now the the brake light won't turn off I have tried everything not sure what could possibly cause the light to stay on. I will eliminate some suggestions, I bleed the brakes, the brake fluid is full, the level sensor is completely attached, the parking brake is not on, I pulled the parking brake completely out, even completely disconnected the sensor thinking it would turn off bu it didn't.

I made a bone head mistake and crunched the steel brake line between the rear axle and the passenger side sway bar mount. Truck is a 2003 F-250 with a 7.3. I would like to go to the auto parts store, get bulk steel brake line and bend it myself. But, I don't know what size the line is or what size the fittings are. Whatare the sizes???

so while replacing the rear brake lines in my 2001 F-250. / 5.4, the flex line that drops from the frame bolts to the axle through the axle breather threaded vent line. The friggin thing crumbled on me and now I can't find a replacement for it. Where I can get it or what it's actual name / part number is so I can call the Ford dealer and hope it's not obsoleted?

Parking brake light stays doesn't come on when the parking brake is engaged. The light DOES come on when starting the vehicle and the gauge cluster cycles through its start up procedure. Couldn't find a fuse that would fix my issue...does one exist?
Truck is an '02 F250 w/ 7.3TD and 6 speed manual.

I'm re-doing the parking brake as part of a rear brake job on my 2009 F250. I need to disconnect the intermediate brake cable at the equalizer, but am having trouble. I've got slack in the cable, but can't push hard enough to get the swaged cable end to move within the connector that's between the equalizer cable and the intermediate cable.
Is there a special tool or some trick to this? If push comes to shove, I can cut the connector (assuming I can get a replacement), but would rather not.
Also, any particular trick to disconnecting the cable to the parking brake lever at the wheel? With that huge spring between the cable bracket and the end of the lever, I haven't been able to move the cable end enough to disconnect it from the lever. Since I don't have the intermediate cable disconnected, could that have something to do with it?

Are the parking brakes on rear disks adjustable at all? Mine doesn't hold very well anymore, but I'm not quite ready to rebuild the whole thing. If there are adjusters (similar to drums), which way you turn them on which side of the truck?
