The Great Smaug

But if they're rigidly connected, doesn't a given amount of pedal movement equal a fixed amount of fluid volume going to each output? The amounts may or may not be equal, but they would be fixed amounts, right? With a rigid relationship between the two, how could we adjust the proportion?

It made sense when I thought about it the other way (lightbulb moment), but now it's back to being confusing.


Thanks a bunch for talking this out with me. I'll get it figured out eventually.

That's not a very good diagram. Why don't ya cut apart the one on your parts truck!

I have the same question about the extra 3/8" or so of radius that the 3/4-ton discs have. Was it really worth stocking another set of parts just for that last fraction of an inch?

The extra two holes in the rotor required a different part anyway.

going to a larger caliper in front would seemingly REQUIRE a larger M/C to feed those larger bore calipers.

I suppose. That being said I have no problem with the couple I've swapped over.

They could have used the same backing plate had they kept the diameters simliar.

Did you ever try running 1/2-ton hardware up front like I did? Or did you just do the 3/4-ton hardware in front with the 1/2-ton MC. Or did you go 3/4-ton all around?

Did you change out your 10-bolt front? Or just the rear?

With my setup, I have no problem locking up the rear brakes. But the fronts are more reluctant.


This never bothered me when the P/S pump was broken. But now that the brakes are much more sensitive (touchy?), I find the rear end locking up more often.

Just did an 8 lug swap on the front 10 bolt... Including 3/4 ton calipers, pads and rotors.

When I first did the 3/4 ton swap on my 1988 V10 Suburban, I left the half ton calipers up front, with the factory 14bff rear brakes. Worked fine.

When I did the rear disc swap, I need caliper for the rear, so I bought the bigger 3/4 ton calipers, and put them on the front, and moved my front half ton calipers to the rear.

I have since swapped to a Dana 60 in the front. It was working fine, but I caught a rear brake line on something and lost my rear brakes. It still works okay, but I need to fix the rear brake line.

Why would you want smaller brakes on a 3/4 ton?

I was thinking of using the larger disk for both of them. Different hub, but the backing plate could have been shared.

Adventure is out there!

We took the Suburban down South (to Iowa) to pick up my M1009 and bring it back up to the Northwoods. Yes, I know my definition of "down South" is different than most of the folks on here, but I live further North than a good portion of Canada's residents.

On our way out of town we spotted this rig at the local cheese shop (that's Wisconsin's form of tourist trap/gift shop):



We couldn't decide whether this was a rig with 2 occupants (so the car is fine, but the RV is ridiculous), or whether the RV was more filled, and the car was kinda useless. Either way, we got a chuckle out of it.

After the obligatory chuckle, we hit up highway 41 Southbound:



The speed limits were recently raised to a whopping 70MPH on this road. Most of the limits around here are 55MPH, with a few 65MPH roads thrown in here and there. I'm not sure where else I can find a section of 70MPH road around here. Were are hours from the nearest interstate.

Traffic was in an especially fast mood for some reason, so I had the opportunity to find out how the truck handles higher speeds.



This picture is misleading, as the gauge reads ~10% high. Actual speed was about 76MPH (or so). But it was kinda odd to see the gauge pegged.

The truck was running really well. Still ridiculously over-geared, but I'm starting to think that I can live with that for a highway rig. I just wish it would get the mileage that the K10 gets.

Temperature-wise, the truck usually ran just a tiny bit below the quarter mark (when it had a fan). Now that it doesn't have a fan, it runs just barely on the other side of the same mark.

For Richard's benefit, I'm including a picture of what it looks like after sitting through 2 stoplights. Noticeably higher, but still on the low side of the gauge.

Heading through Green Bay & the Fox Valley, we waved at the EAA grounds in Oshkosh. Have some happy memories from there.





Stopped for fuel in Fond Du Lac. This site was chosen because it was where my 2-month-old daughter decided it was time to start crying.

While stopped, I noticed this fuel (presumably) spatter on the back of the truck. I haven't noticed this before, but I think the accumulation of unburned fuel has something to do with my crummier fuel mileage.





So...this is a sign of tired injectors, squirting a liquid stream instead of a vapor cloud?

We then ran into Midwestern weather.

This:


Turned into this:

And then things got a little dicey. We pulled into Madison with this view:





Not blizzard-quality white-knuckle driving, but not very fun, either, to run into that weather in the middle of that town's traffic patterns.

Oddly enough, my rear brakes have been bugging me for several hundred miles. In these driving conditions, the truck handled perfectly. No weird locking up, no pulling to either side, just normal driving.

And then the pictures stop for the night. The storm got worse while we crossed town. As we pulled off the beltway onto our exit (151 South), I hit a large puddle (water flowing over the hood and windshield). Within 1 second, I had a squealing V-belt. This exit is under construction, with a slightly-modified-but-still-nasty traffic pattern, so stopping to address the issue wasn't about to happen. Before I got out of the construction zone (2 miles, perhaps), I was no longer seeing charge voltage on my voltmeter.

I pulled off at the first opportunity, and found I was no longer in possession of an alternator belt. This lead to 2 towns' worth of scrimmaging to find one, before continuing our trip.

15 miles of searching for an open store, in a T-storm, with a screaming baby, a concerned wife, wipers and headlights rationed to conserve battery power, and then stripping out the threads in the alternator casing...we made all kinds of great memories that night!

Aside from a 1/2-hour delay, all was well. I've gotten good enough at doing this alternator belt that I have my socket sizes memorized.

Actually, I had them sitting on the front seat because I still didn't trust this alternator (it's weak, at best).

The rain let up after that point, and we continued down to Iowa without any other issues.

I'm really starting to like this truck. Road trips just seem more fun in old iron, for some reason.

 

[TREA18]

Great stuff. So, you both drove old iron back home?

The 3 of us rode down in the Suburban. We towed the Blazer back on a trailer. Further adventures to follow.

We're heading back your way for Labor Day weekend. You interested in meeting up when we cross the border?

 

[streetrodchev]

Let me know if you want/have time to stop by my place on your way to/from Iowa.

It could be a possibility. What will be your travel days near Dubuque?

Down in Iowa, we spent a few days visiting with folks and worked on several little fun projects. First up was tearing the headliner out of the Suburban. The cloth on the front half has been hanging down far enough to entirely block the view of the rear windows. The rear half looked decent enough (though it was also deteriorating).



I don't know if there are any upholstery shops close to where I live, but I have a history with a one-man shop down in Iowa. He quoted me $85 to recover this headliner in new insulating cloth. Haven't found any better deals around, so I dropped it off while I was there, to be picked up next time I'm in the area.

Now, the liner-less truck has much more headroom. Wifey is happy!



She then asked me what I'd think of leaving it that way, and not bothering with any headliner (CUCV-style).



And the sunset was neat.
