Making It Right: Tacoma-to-Tundra Brake Upgrade

August 19, 2019.

We all have to eat crow sometimes. We've all made mistakes. The most important thing is how you react in those situations. So, "give me a fork!"

A couple years ago, as one of my early modifications, I added Tundra brakes to the Tacoma. This isn't anything out of the ordinary - it's one of the more common mods in my opinion. In doing so, I had a decision to make - the same decision that everyone who does this upgrade has to make:

How was I going to connect the new 13WL calipers to the Tacoma?

I of course had all the options that everyone has:

  1. Use the existing Tacoma brake lines and banjo bolts, very carefully drilling out the end of the banjo bolt so it would fit the shorter threaded insert on the Tundra caliper.
  2. Purchase Wheeler's Stainless Steel front brake lines, since they come with a banjo bolt that is short enough to work with some Tundra calipers.
  3. Purchase an LCE Perfomance Tacoma-to-Tundra Stainless Steel Brake Line Kit that replaces the banjo connection with a hard brake line, just like the Tundra has from the factory.

I knew there was no way I was doing option 1, and the price difference between option 3 ($180) and option 2 ($60) seemed to me like a great reason to go with the Wheelers lines. After all I thought - the Tacoma uses a banjo bolt from the factory, so it must be OK to do the same with the Tundra calipers. And, for two years, it worked out great. That is, until one of my calipers seized up on the trail and I had to replace it. As part of that process, I learned the hard way that not all Tundra calipers are correctly remanufactured to work with banjo bolts. At first I thought this was super weird, but as I thought about it, the reason for this dawned on me: if you're using the Tundra 13WL for it's intended use - on a Tundra - the special machining needed to use a banjo bolt is unnecessary, since the Tundra doesn't use a banjo.

And that got me to thinking - yes, a dangerous state for my simple brain - what if another caliper failed on the trail? Would I be able to find one that works with a banjo bolt?

And so, I decided that the right path forward was to pull a fork out of the drawer and eat some crow. It was time for me to dish out a bit more money and make my Tundra brake upgrade right - by installing the LCEPerfomance Tacoma-to-Tundra Stainless Steel Brake Line Kit.

It's a simple job, so once the parts arrived, and with a few trips coming up, I wasted no time in getting going. Oh, and I decided to install new brake pads at the same time - since mine were worn from being "stuck on."

The first step in this five-step process is to jack up the truck and remove the front wheels. Always a really weird way to see the truck - sort of vulnerable or something.

Next, it's a simple matter of removing the existing brake lines from the frame to the caliper, as well as the bracket that holds the line to the spindle. The hardest part of this process is removing the small retaining clip that holds the brake line at the frame - but a few minutes with some needle nose pliers and you should be able to get it out.

Once you do, a 10mm flare nut wrench will separate the soft line from the hard line and you can cap the hard line with a vacuum cap so it doesn't leak everywhere. Then, use a 14mm socket (set) to remove the banjo bolt from the caliper, as well as the bracket from the spindle. Note: make sure to pop out the ABS sensor clip from the bracket as well if you've got ABS.

With everything removed, it's simply a matter of installing the Tundra-conversion hardware. I started by installing the supplied bracket onto the spindle, and then the hard line between the caliper and bracket. This took a little figuring since LCE doesn't send any instructions, but the hard lines only fit between the caliper and bracket in one configuration, so you'll only need to try a few combinations before you get it.

Then, it's a simple matter of installing the softline between the two hard lines - do the one at the bracket first, then pop the vacuum cap off of the hard line at the frame and make the final connection using you 10mm flare nut wrench. Pop a clip on each end to secure the hard lines, and you're nearly there!

With everything in place, bleed the brakes using an 8mm flare nut wrench, starting with the passenger- and moving to the driver-side when the brake fluid is bubble-free. Reinstall the wheels, and know - no matter what Tundra 13WL caliper you install next, you'll have no problem with leaking brake fluid!

Epilogue (aka Rant)

With everything now working, I've  got a little something to say about LCEPerformance. Actually, two somethings.

First, they have 3 versions of their brake line conversion kit - a standard length, and then 3"- and 6"-extended versions. Since I figured I'd replace the rear brake line too (the kit comes with a rear line), I gave them a call to confirm that the extended line was for the rear only - after all, the front lines would be the same regardless of lift, since the front geometry is limited by the control arms and spindle - any suspension lift only affects where the control arms are positioned at rest.

But, two people at LCE insisted that if I had a lift, I needed extended lines because the lift would move the calipers further away from the frame. And, when I asked about just getting a longer rear line and standard front lines, they informed me that the price would be significantly more for "custom length" lines. Even though the "custom" lines were a length they already sell.

Which brings me to the second item: price. The LCE kit is $180 or so shipped. That's a ton of money for some brake lines. So, as of now, I'm in the Tacoma-to-Tundra Brake Line Conversion Kit business, with two options. You'll note that neither kit contains a rear brake line - because that's not what the Tundra upgrade is about.

  1. Basic kit. Contains the necessary hard lines, OEM-style soft lines, brackets, and clips to convert the front end of a 1st gen Tacoma to Tundra-style brake lines. $100
  2. Stainless Steel Kit. Contains the necessary hard lines, Wheelers stainless steel soft lines, brackets, and clips to convert the front end of a 1st gen Tacoma to Tundra-style brake lines. $130

To make shipping reasonable, I'll be doing these in batches. Yell if you're interested.

    Interesting on the rant / new "business"...

    I already have implemented Option 2: Purchase Wheeler's Stainless Steel front brake lines, since they come with a banjo bolt that is short enough to work with some Tundra calipers"
    with extended front & rear lines from Wheeler's.

    How long are the lines for the purchase option 2: "Stainless Steel Kit."? I wonder if you can cut costs some by allowing those of us already with the stainless braided lines to insert the hard lines in the end or if there will be too much extra length flopping around.

      Unfortunately, you need new soft front lines when you do the hard line upgrade because the hard line connects to the soft line using a threaded connection, not using the banjo bolt that we all have on our Wheelers (or similar) Tacoma soft lines.

        Ah, ok. Does the "Stainless Steel Kit" come with a rear line? I don't need one of those as I have already installed a extended one in a stupid red color.

          Nope, as noted above - no rear line... Since that's not what the tundra brake upgrade is all about anyway. 😀

    Just one note on another option out there. Raybestos makes a brand new Tundra caliper that has the machined surface ideal for a banjo bolt. No core charge and it works really well. Also has a 10 yr. warranty they say. Of course out in the boonies, you want more options versus less, so I totally understand your course of action. Paid $200 flat for the new calipers shipped to my door, so we'll see how they hold up. Cheers!
