The ABS actuator is electronic in the 200 series, as it is in many modern cars. They control the brake feel so a 100 pound Asian lady can press the brakes without it feeling harsh. But it’s adjustable. I just recently had it done on my Tundra and it made a difference in feel. It just engages sooner. Go to a shop that knows Toyota’s and it shouldn’t take them much more than 30 minutes to adjust. If you’re a loyal customer, they might not even charge you.

Can someone verify whether the brake sensitivity is adjustable? I love the 100 brake responsiveness and would like to make the 200 brakes feel less spongy.

TRD pads seem to be well reviewed, so I’ll go with those next time as well
 
Buy a 2016+
I was just going to chime in that I think the brakes are not that bad given the weight of the vehicle. Looks like @04UZJ100 speaks from good experience based on his stable of vehicles. Sounds like the larger front discs made a difference - makes sense. I wonder if you could up-fit 2016+ front discs or if it would require a whole new ECU and ABS unit too...... then I guess there is the calipers, caliper carriers and...............not worth it.
 
Several things you can do from maintenance to modifications, depending on what you're looking for. The 200-series brakes are strong. Yes, they feel different than most cars, needing more brake pedal travel to effect modulation, but I believe this is by design.

Are you on stock diameter tires?

1) Brake flush
2) If the brakes are worn: change rotors (recommend stock rotors) and pads (see next)
3) Upgrade pads. Any number of great sport pads out there including TRD, Stoptech Sport Pads (TRD rebrands these), Hawk HPS, etc.
4) Upgrade to stainless steel brake lines
5) Tundra BBK (makes brake dimensions equivalent to 2016+ cruisers)

Yes there are some threads on this in the forum. @bjowett was the fore runner on swapping over the Tundra discs and calipers to the LC, but there are folks who have done the newer LC brakes on the older LCs as well. Calipers are the big expense but there are other changes with brake line fittings and dust shields to account for.
 
My 2 pennies are the stock brakes are pretty damn good. Probably don't need to say this but check obvious things first. My neighbor was complaining about really soft brakes and a little vibration when stopping.

That's one of the rear rotors. It's a 2011 with 189k original rotors. I replaced them with OE rotors and Tundra pads and did a proper bed in. Unfortunately it needed 2 rear calipers as well. The pistons pushed pass the point of no return on one side. The brake lines where almost gone as well in the back so she sprung for the up grade to stainless lines over OE.

The Tundra pads all around, new rotors all around and the stainless lines worked out pretty well. She is the original owner and said it never braked so firm even when new. I am thinking about replacing the OE brake lines with stainless for what it's worth.

Bless the rust belt
 
On my FJ62 in the early 90's I learned the trick of pumping the e brake a dozen or 2 times which firmed up the pedal considerably. It had rear drums. Up front I upgraded to 4 runner calipers and a 1" master cylinder from the T100.
My 2020 stops fine and I'm upgrading my boat trailer from surge disks on the front 2 axles to electric over hydraulic. Hauling it with my 7.3 Excursion is no problem but I'd like to tow it with the 200 and EOH should really command the trailer brakes.
 
So is there a magical 30 minute adjustment that a seasoned Toyota tech can perform to make the brakes less spongy?
There is an added element of safety with "spongy" brakes with a heavy vehicle. The last thing you want to do is lock up a heavy ride especially in bad weather or even on tarmac. Perhaps leave at least 50' in front of the person you are driving behind at speeds over 65mph. Approach curves with caution and just be aware you are driving one of the heaviest SUV's on the market. It's not a sports car even with KDSS.

Besides brakes give a ponder on putting in heavier suspension all around. That will help with heavy breaking all around.
