Well, drove some more today and love this mod. the line finally showed up, but I’m already enjoying my “dremmel mod”, so if anyone wants to completely remove the accumulator and wants the Acura braided line, let me know.

Good stuff!

Can somebody explain how to (or point me to instructions for) bleeding the clutch after doing this job.

It has been noted many times in this thread.

@ShirtTucker has some of it described here:

All right you freaks, geeks, @tonered , @Shellshock, and @Grossomotto , I finally tackled the metal clutch pedal install. Yes it's as much of a pain in the a$$ as it looks like it might be. It'll help to be less than half a century old, and have your Webster's Dictionary of Vulgarity handy.

1. Note: Your truck may have a different layout for the clutch reservoir. Toyota uses two different braking/clutch systems. In my case, the clutch shares the system with the brakes. Shove a bunch of rags into the area below the lines going to the clutch master cylinder; you do not want brake fluid all over your paint. Remove the lines going to the clutch master cylinder. Clamp off the rubber hose as close to the firewall as possible, unless you feel like bleeding your brakes. After you remove the rubber hose and steel line, have a helper slowly depress the clutch pedal while you hold a small container, or more rags, under the two ports in the firewall. This will remove most of the fluid in the master cylinder, so it doesn't end up inside your truck.

2. Now the fun starts. Contort yourself under the driver's side foot well, so you can look at the left side of the clutch pedal assembly. You'll see an electrical connector about midway up. This one is fairly easy to remove.

Now look at the very top of the clutch pedal assembly. There's another electrical connector up there. There is just enough play in the wiring to allow you to remove the clutch pedal assembly from the firewall, and THEN unplug the connector. I recommend waiting until that point, just don't forget to disconnect it.

3. It's time to remove some nuts and bolt. You WILL need a universal socket joint and long extension. I used a 10" extension. You will also need a small 1/4" ratchet and 1/4" 12mm socket.

On the left side of the clutch pedal assembly, you will see a 10mm bolt with a Phillips head. To the right of that bolt is a 12mm nut that is barely visible. Use your extension, universal joint, and sockets to remove them. Good luck.

4. Were you lucky enough to be able to remove the nut and bolt in step three? Well, you're about to get bitch slapped by karma. Position yourself on your back and look up to the top of the clutch pedal assembly, around the area of the top electrical connector I mentioned earlier. You have to remove a 12mm bolt by feel, using your 1/4 socket wrench and socket. The bolt head points to the rear of the truck.

5. You still here? Good for you! Put an old towel on the driver's side floor to catch any brake fluid as you remove the assembly. Remove the last, easily accessible, nut, and maneuver the assembly out of the vehicle. Don't forget to undo that upper electrical connection!!!

6. Now it's just a matter of disassembling the old parts and assembling the new. Installation is the reverse order of removal, but you'll need some way to keep the left side nut and bolt in the socket as you feed them in with the extension. I used some painter's tape.

7. Bleed your clutch. Use an assistant. The clutch pedal will not return on its own until almost all of the air is out of the system, so don't freak out if your assistant has to pull the pedal up after depressing it each time. You won't succeed by using the gravity bleed method in this case.

Was it worth all of the effort? I suppose so. My clutch had *just* started making the creaking noise, so something needed to be done anyway. The engagement point is now midway though the pedal travel, instead of at the very top, which is nice, and it's dead silent at the moment. I really wanted to replace the stock spring with a linear spring, but the 3rd gens are missing an attachment point for the spring It could probably be duplicated by hose clamping something in that area, but I didn't want to spend any more time with my body in that crazy position.

Very few dealers will do modification work. Most lift kits and project trucks that you see at dealers are either done by secondary shops or a select group at the dealer. Typically, they work to what the OEM gives them.

Learning to bleed is a good thing. All vehicles should have a bleed every few years at a minimum. Try it out on brakes as they are a bit easier to do. It is something that can be self taught. Basically, never relieve pressure on the pedal / lever until the bleed nipple is closed. That's it.

Brakes are:
-- Pressure on the pedal
-- Crack the bleed nipple, let fluid come out, and close the nipple
-- Let the brake pedal come back up
-- Pump the brake to regain pressure
-- Repeat until virgin fluid flows out

Clutches are:
-- Pedal to the floor
-- Crack the bleed nipple, let fluid come out, and close the nipple
-- Pull the pedal up off of the floor
-- Pump the clutch to regain pressure
-- Repeat until all air is out / virgin fluid flows out

Seriously though, if I can ham-fist my way through it, most anybody can get there.

Of course, there are also remedies for mess ups that happen.

My wife drove the truck for her first time since the accumulator delete. First thing out of her mouth when she got home was "that clutch is soo much better."

Edit: No I did not ask her about it and I had even forgotten she had not driven it without the accumulator.

It is an odd game changer and an absolute mistake to be a permanent thing.

I'm glad that she liked the ADM.

sdshack · Nov 24, 2021

Anyone in San Diego/SoCal who could help me out with bypassing the ADM?

I’ve never much cared for the inconsistent clutch feel (or lack-thereof…) in the Tacoma, but after being home for the holiday and driving my M3 a lot I’m fully realizing how much better the truck could be. I NEED this mod lol.

Finally deleted the accumulator and definitely enjoy the ride without that little bastard buffering in/output.

Why Toyota has these installed at all is a bit of a mystery, since it only seems to interfere.

ETA: more info in the build thread

Need to find one someone has taken off for the line so my buddy can throw it on his mill. I like things overdone, nice job!

I was thinking of starting a "pay it forward" chain for the dremel method with my take-off accumulator.

If you're interested I can ship the unit to you.

possibly, I’d even be interested if you have a guy to do the milling pay some to have it done prior to shipping.

I’ve got one that needs a home as well. I used the Acura line and don’t really plan on going back.

in for a milled one!

Same (big time)!

I’d happily pass my stock one and $$ along for a finished product.

Anyone in the Auburn Mass area that can do any of this mod for me?

This isn’t a milled/finished product it is the stock piece. $30 shipped. @96Yota asked for it first. I bet @philth has one he sell someone too?

Formidable · Dec 2, 2021

Anyone have the part number for the OEM accumulator plate?
