I finally got around to doing the Tundra brake swap! A big thanks goes out to BFAD for his write up, it defiantly took all the mystery out of the process.

Before –
After –
My old stock brakes were shot (35’s and heavy beadlock wheels will do that), the rotors had started to warp, and even before that I felt uneasy coming down a big hill toward a stoplight. There just wasn’t enough braking power for the wheels and tires.
Everything went smooth for the most part, but I did run into one problem. I bought two calipers from Napa and I started on the passenger side. It went great, no issue’s, just your typical brake job with a little trimming. I moved over to the driver side, attached the brake line to the caliper, and what would you know, big problem. I tightened the brake line down and it bottomed out on the caliper, but the flared end of the hard line still had 1/8”+ of play inside the caliper. For the hell of it I unclamped the brake line and it leaked brake fluid like crazy. I took it all apart and measured the thread depth to the flared surface inside the caliper, and it was way too deep.
It took me a week to get these calipers, so exchanging it for another one wasn’t much of an option unless I downed the 4Runner for a week, or reinstalled all the stock stuff and re-bled the brakes. I figured it was worth a shot to fix this one; so plugged the hole, took a good 1/8” (or more) off the caliper, reamed it, and chased the threads. The fix worked great and it’s not leaking. So far the brakes feel great; the 4Runner actually wants to stop and I don’t get that horrible feeling when I see a stop light change red in front of me. The brake pedal does have more travel to it, but once they start working they work good. I’m going to re-bleed them and see if that helps at all, along with checking the adjustment of the rear shoes.
