Ford 7.3L Power Stroke (1999-2003) :: Brake Fluid Dripping Onto Front Tire - Use Cruise Control?
Apr 23, 2015
OK, so a friend's F150 just went up in flames in his driveway and he told me that the problem was the hot link behind a plastic/ rubber barrier at the main brake cylinder. I had a recall notice on my old truck but since I left the US and took the truck I never paid much attention to it, thinking typical overkill. Now I already heard from another buddy who caught lit brake fluid dripping onto the front tire and got the fire out before it spread and looked up the info today. Looks like our trucks are affected. Best to unplug the harness that goes into the brake master cylinder will prevent this problem from occurring? I never use cruise where I am, the roads are too small and slow.

I have an 02 f150 5.4 and since I got it it hasn't had cruse control. I went to a local ford dealership and they ran the vin and didn't find any recall on it. Under the hood on the master cylinder there is brake fluid coming out of the brake control switch. Would I have to do something with the harness too?

While turning very slow and sharp on the farm, I heard a pop under the hood. I then lost power steering and brakes. I saw power steering fluid spurting in the left tire well behind the tire. Look under hood and saw fluid coming from a fitting on the side of the power steering pump. I have attached a photo....one photo with nothing and then other with a screw driver tip on the fitting.
It appears that the the pressure fitting blew out the side when I turned sharp. It has a nut from which it came (compression of some sort?). I can push the nipple of the fitting back into the nut but I guess the pressure is gone.

This has happened 3 or 4 times now while driving down the road. Just cruising down the road the CC will just cut out. I'll hit the "set accel" button on the wheel and all is good again until it randomly decides to do it again.
The only thing I've changed recently is the rear end speed sensor to cure the ABS light. I wouldn't/didn't think this would have any effect on the cruise control, but IDK, maybe I'll put the original one back in and test it.

Cruise just stopped working. The fuses all check out ok. What would be the next simplest thing that I could check before turning the problem over to a mechanic?

So the PO tells me he was flying down the highway and went to cancel his cruise control and it wouldn't turn off. He claims he made it to the shoulder of the highway and killed the ignition. When he restarted the truck is was turned off and it hasn't been used since. I tried to use it yesterday but couldn't get it to work?
So I do the search and find out that the deactivation switch is most likely the issue. I just picked up a new one today and was curious if it is just a R & R thing or if it needs to be bleed off or something? Is there a need to test it or just change it out? Sound like something that would cause these issues?

2003 F250 7.3... I noticed a water leak dripping down onto passenger side front leaf spring. I saw this before but attributed it to the AC (which kicks butt) but haven't used the AC. No scent to the clear fluid, temps all look good. Running fine. Where does the AC discharge go? Could AC be on (not on AC but set in blue zone on dial)? Reservoir looks ok but could e small volume of drips.

RPM's are dropping way off when coasting downhill while towing (as if the motor shut down), CC is on and maintaining desired speed. When at the bottom of the hill, all of a sudden, with a big bang(in the motor) the rpm's have came back up and you drive on down the road as normal. This seems to happen only when towing. "99 F250 7.3 I haven't pulled any codes as of yet. Whats happening?

I just noticed a small leak (red PS fluid) coming from the rear of my hydroboost in the truck (while working on my shift tube replacement this past weekend). The carpet is not wet, but there is a drip hanging on the rear end of the HB waiting to start leaking itself on the carpet. Also, there appear to be no issues with either braking or steering -- all is smooth, firm, steady, and quiet.
I have nearly 290K miles on the truck, replaced the Master Cylinder probably 8 years ago at roughly 150K miles. I no longer spend nearly as much time on the road as I used to (probably 8K miles per year now compared to a previous eight-year long run at 18-20K miles per year.
Questions.
1) Should I go ahead and replace the HB before it gets worse (I don't know how fast the fade when they start this process)?
2) If I replace the HB, should I go ahead and proactively replace the MC along with it since I'll have the whole system wide open?

Stopped after a hard pull and noticed I had coolant dripping off the front sensor on the Brake Master cylinder. Coolant level was down in the Degas bottle. Searched everywhere for the source of the leak, and couldn't see anything. Today the drip had stopped, but when I squeezed the rear heater return hose under the Degas bottle it appeared to have a wet spot form.
I'm thinking I have a very tiny pin hole, and plan on pressurizing the system to see if I can determine for sure this is where it is. Before I do though, where this high pressure leak might be coming from? Degas bottle and cap is less than a year old. Doesn't appear to be any signs of leaks around the clamps. That rear heater hose.

Re packed / cleaned my hubs. Did a 600 mile trip and front driveshaft is locked again. Am trying for first time soaking them. They are in tranni fluid right now. I can't afford warn hubs. Is there any other tricks? Or will I have to soak them every few months?

I was out with the F350, drw, automatic, 7.3, 4 x 4, yesterday about 30 miles from home base. The transmission started pumping fluid out the front like I have never seen before. I am not talking a drip, I am talking a stream, a big one..... almost like pouring coffee from a coffee pot. I noticed it when I was backing into unload and was leaving an oil trail, a quite obvious one.
We took off the tc cover as it was coming off that to find a dry tc and flywheel, but fluid running out off the case. This is the second time this trans left me high and dry in 165k miles. The first time was a stripped tc/ input shaft. We repaired the transmission then but I don't think we replaced much besides being sure no debris went though everything, fixed what was broken. That was about 25,000 miles ago.

I have an oil leak under the flywheel cover that gets worse as it runs.It is dripping directly off the middle of pan below where the torque converter attaches and as i said it gets much worse when its running which makes me think rear main seal....

Have another oil leak, just finished the pan flange gasket last weekend, made it 150 miles, now a new leak.
Took the spider out and everything on top, cleaned the valley up good, the fired the truck. HPO lines are good, but have a drip off the back and bottom of the HPOP, when I reach under it from the back, its right below the large 2 inch circle.
What this might be? was thinking possible orings somewhere under there where it seats, but its been 6 years since I replaced all the orings, don't remember exact layouts.

1. What is the "stock" tire size for a 2000 F350 7.3 Super Duty 4x4 SRW?
2. Is there a way to adjust PCM to accommodate different tire sizes?

Took the torque converter cover off and this is what I see. Before I took it off the cover looked oily. Prev I replaced the EGR valve and some other sensors and there was oil on top of the engine. Does this look like a rear main seal or oil dripping from the top of the engine?

I've been having transmission fluid leak from my truck for a while now. Very slow leak. At first I thought it was a hard line and replaced it but it was still leaking. Then I think I found where it was coming from. It looks to be fluid dripping on the bottom of both sides of my intercooler? On both identical spots. I am guessing perhaps I had a crack on my transmission oil cooler and driving blew it into the fins of my intercooler. I took my old one off and couldn't visibly see one. I have a brand new trans cooler installed now. Haven't drove yet as I am waiting on brake parts? I couldn't think of anything else on why it would leak off the intercooler?

I've got a late 99 7.3 truck that I just recently did a lot of work on. I installed a new turbo with bellowed up pipes and a new exhaust system and when I went to start it up it started leaking fuel in the back pretty badly. Initially I thought it was the banjo bolt or the passenger fuel line but looking at it more closely I realized that it's not coming from there. It's dripping all over the side of the starter and is collecting at the low point of the metal lines down below. I also saw small droplets coming out of the up pipe where it meets the manifold but it looked like nowhere near enough to produce the kind of leak I'm seeing, also I know fuel shouldn't be coming out of the up pipe to begin with. This is really annoying and I would like to drive my truck again.

I noticed yesterday that my tire on the driver's side has rubbed a flat spot on the rubber brake hose. I bent the metal tubing so that it doesn't rub any more, but should this be of great concern? Obviously I'd hate for it to rupture, but it looks as though it's not too bad.
