    I actually ended up sinking some money into the 14wb calipers by purchasing and having machined remotely. I was pretty bummed out thinking I had made an expensive mistake. Actually the only difference between the two is the bolt hole size (12 versus 14 mm). With the 14WB you can keep your old bolts and and just slide a cut to length piece of aluminum pipe in the hole reducing the hole size from 14 to 12 mm. There will be no issue and 14WB will work for the conversion. Of course I would have preferred to have the 14WA calipers but I made the best of a bit of a situation. Others have added the small piece of aluminum tubing in the bolt hole for 14WB's and had a successful install. If somebody has the part number for 14WA please provide.

    I am getting it installed on 1/11/21. I will post something brief based on experience.

    So what is the summary of the last six pages? :) I read the back and forth about the T100 MC and different calipers but I am still wondering if there's anything conclusive on how to get better braking performance.

    :notsure: Seems like the 14WA upgrade does provide better braking performance but dealing with a potential mushy pedal doesn't seem fun. But if you have an extra $1900 laying around you can get a 6 piston 340mm big brake kit that should stop better than what most of us have!

    Too many
    This is a good summary but it's worth noting that only 2 of us reported the mushy pedal. 1 member didn't have that problem and I spoke to 3-5 on Instagram that also had success with no mushy pedal. I'll see if rebuilding my master cylinder fixes my problem or not.

    Appreciate that. Can the 14WA be used with 16" rims? I read somewhere that 17" wheels are required for any kind of bigger calipers.

    I remember reading that 16" rims will NOT clear the 14WA's. @FirstGenVol ?

    17"+ only

    14WA greatly improves braking and stopping power. Not so much pedal feel, maybe slightly.

    A brand new MC helped alleviate the mushy pedal even more after the 14WA. Lots of 1st gen Tundra/Sequoia guys are reluctant to replace with a new one. I read many posts of people seeking out used ones from the junk yard. Why? Just buy a new one, they're cheap. These rigs aren't getting any newer. These are 15-20 year old trucks with 200k on them. Just because it's a Toyota it doesn't mean it's maintenance free to the point where one can drive on all original everything.

    That link from @Lil Steve has a 16” option. Those 3 piston cylinders action look sweetly, but woooooweeee! on the price tag.

    Just finished the upgrade on my 2006 DC. It works great. No significant pedal squish but a big difference in braking. I occasionally tow about 4000 pounds in Colorado foothills and mountains and will appreciate the extra stopping power. People need to be aware that different year 1st Gen Tundras have different MC's. I tried to see if a T100 (with ABS) BB and MC would work and it won't easily for fit and tech reasons. As noted earlier, the 2006 DC (and maybe others) have a more complicated MC (thanks for explaining Geoffrey Beers). Also, don't make the minor mistake I made and order 14WB (online parts systems may point you to them). You can recover if you order 14WB but you will need a piece of aluminum tubing to supplement the mounting holes where 14WB holes accept a 14mm bolt and original Tundra calipers take 12mm bolt (at least on my 2006).
    Thanks for everyone's information share towards getting this project completed.

    I'd say before you go for the big brake upgrade, try the easy things. Adjust the rear brakes correctly, adjust the proportioning valve, flush the brake fluid and get good quality brake pads. I've been very happy with my braking performance, but only after I did all of that (but I don't tow). When I first got mine the brakes were pretty bad.

    I used Centric pq pro on my sequoia and I've been very happy with them and for $35, definitely worth it.

    If you're lucky enough like this guy, stick with that plan. My buddy has an '02 with a very good pedal.

    I and many others went through years and years of horrible brakes on the 13WL calipers which are better than the 13WE.

    At least a dozen flushes, brand new OEM pads, rotors, you name it. The combo of 14WA plus a new master cylinder gave my sequoia a fresh breath of air. Brakes feel modern.

    Not to sound like a broken record, but this mod is an A++. By far the best modification I've done for drivability. Especially after adding a lift suspension and bigger tires.

    If you're on the fence, DO IT.

    You are rich and flush with capital after your high dolla A/C install. Do the Triple Pistons! Stimellis should be in the mail, too. Do it!!!

    As you know, hand.........jobs pay very well. Yours are probably covered in Jerrgens, mine are covered in “pookie” and blue pvc cement(I don’t like drips visible so I always wipe after I press in a joint)
    But I think I’m on the same boat as @rock climber, I will get all the current mojo flowing first, and proper. I’m not getting rid of it anytime soon, so I’d like to go thru a set of pads myself and go from there. Even our 4runner did great on oe pads, it could have gone longer with better driving habits but 85k is good in my book

    Whats up lords, long time off here, good news tho..
    Stoked to get the gx upgrade on my tundra today.
    Also happy to offer caliper machining in north county SD.

    FARO'd the caliper at my new work.
    wanted to check parallelism and such for my jig design to pass it on the end mill.

    Heads up from DirtyDeeds, even with a 17" wheel, the caliper width wont clear all wheels. He has methods and wont clear.

    I really need to rebuild my master cylinder and see if it helps.

    @empty_lord is there a paper gasket you recommend for going between the MC and booster? I need to buy one.

    I'm curious, would the GX460 rotors fit on the 1st gen Tundra/Sequoia's stock brake callipers or are they too wide? I want to do the BB upgrade also but not financially able to and I hate how soft my brakes feel. I have to double pump the brake pedal when coming to a stop. Pressing on the brake (without pumping) would go a little more than half way with a lot of strength behind it. Only after pumping the brake pedal is when I feel the brakes engage about 1/4 of the way pedal depression.

    If your main complaint is the mushy pedal then this upgrade isn't going to help. It may in fact make it worse. I think what you are asking is if you can keep the same calipers and use bigger rotors? I don't see how that would work. The first page shows how much wider these rotors are.

    Sounds like a bad master cylinder. Not something a bigger brake caliper or rotor will help with.
