What Are These Tools, part II?

Last batch (I hope) of mystery tools out of my uncle's toolbox.

1.

Obviously a clamp or wrench of some kind.  Ends have some very specific bends and castings that make me question what is is for.

2. Another wrench of sorts?

3. Wrench with spring loaded jaws and a head that can pivot side to side. Craftsman lable. For pipes?

4. I want to say I've see these thing used on car battery terminals,  but I'm not sure. Connecting post is sprung.

1. Drum brake pliers. Used for installing and removing the various springs.

The first one is definitely a brake tool  - for drum brakes.  Those pieces on the end of the handles are for removing and replacing the springs that hold the shoes in place.

I don't recognize what the pincher looking end does.  Maybe something to do with the old mechanical brakes Model T's and Model A's had before Henry decided to pay the patent fee to be able to install hydraulics.  

The one with the black handle looks like something I have seen used to tighten up old fashioned axle bearing retainers.. This is a guess.

The swivel head one with yellow paint looks like a tool I have seen used to adjust tie rods when adjusting toe.

No clue about that last one.

#1 is a brake spring tools for drum brakes. I use one all the time.

#3 is a basin wrench for tightening the nut on sink drains and faucets.

#3 is a plumbing wrench.

you can reach up behind a kitchen sink and unscrew the faucet.

On that first one, the backside of the pliers is to remove the spring that points out at you that holds the shoes on.

You'll find it doesn't work for that, there is a different tool for the hold-down spring: 

The tool in photo 1 has one edge of the circle lower than the other. It's for removing the return spring from the post. You slip the hollow end over the post, put the tab on the side in the open end of the spring and rotate it to disengage the spring.

I have the same battery terminal puller in my toolbox.

#4 looks like it's some sort of helper tool valve adjustment in side valve engines.

#2 looks like a flywheel turning tool.  Used to rotate the engine instead of a socket on the  crankshaft balancer bolt 

#2 is to tighten the locknut on a sink drain.

1,2, and 3 are definitely correct (brake pliers, flywheel turner, basin wrench (plumbing stuff)  Not sure on #4 but it looks like a valve spring holder but maybe a little wimpy.

And we're done.  Brake spring tool, flywheel turner, and basin wrench.  #4 is very familiar but IIRC there is something missing.  Reminds me of part of a valve spring compressor.

Basin wrench is extremely familiar to me because I just used one to install a new kitchen faucet.  I'd rather have used a set of crow's foots, but, well...

Monty ......who's our winner?

I think I figured out what #4 is. It's part of a valve spring compressor,  right?

In reply to Appleseed :

Right.  Just came to post this.

Thanks, guys.

Those brake drum tools are life-changing. But I do drums so rarely that I misplace mine between jobs and try to press on regardless. Which always ends poorly. 

I have demonstrated the drum brake spring pliers to hundreds of students over 30 years of instructing. Then I would step back and watch them actually remove and replace the springs. Drum brake work is very easy with that and the retainer spring tools.

There was a guy on the HAMB who's handle was Cyclops.

In one of those "meaning of your screen name" threads, he mentioned that he earned his name installing brake springs with a pair of vice-grips.

Okay instead of starting a new thread - can I just add to this one? My brother in law cleaned out his late grandfather's garage the other day and found this. What is it for?

Almost looks like a homemade bottle clamp, like you'd see on the back of a propane forklift.

It's a work light, helps you see in the dark.
