Good afternoon, been a while since posting as I can usually find my answers here by searching! I've recently acquired a completely stock FJ62 with 110k miles. It looks to have been sitting for some time and has a brake leak at the right wheel, brakes are crappy as you might expect but not just a leak. It has 15" wheels with small rotten tires. I'm planning 2.5in lift and all four brake repairs/front knuckle rebuild at the same time to make my life easy.

I was considering the Front Range Offroad front disc brake upgrade at the same time (03+ FJ Cruiser, 05+Tacoma, GX470, and 00-06 Tundra brakes). Read on here than rear disc upgrade not necessary for normal weight vehicles.

I've restored vehicles and found its often easier, but not cheaper, to just replace everything at the same time and get it right at the same time rather than replacing it piece by piece.

So my question is:
1. If I did this upgrade should I also upgrade the Master Cylinder and booster? With larger calipers and rotors with larger 16" wheels and 33" tires so don't know if it would be better w larger MC/booster, too? If so Man-a-fre has 1 1/8" MC with included larger booster? (fj62 has 1" MC and dual diaphragm booster already).
2. I've seen some of the knuckle rebuild kits state they fit FJ60/62 up to 1989, but mine is a 1990? I doubt they changed the knuckle for one year? Are all FJ62/60 knuckles the same?
3. I have AISIN locking hubs - plan to replace at same time, I assume I can still use same locking hubs if I do brake upgrade?

Sorry, I've called and emailed Front Range a few times without response. I know how to fix and diagnose brakes, done disc conversions, etc...

Talk to a local shop, give @cruisermatt a call and he can get you the best set up for what you want to do. He's over near Orlando.
 
I've got a FJ62 that I put an OEM Aisin MC in. Along with that, I readjusted the LSPV to match the ~2" lift and put new rear drums/shoes in.

The fronts are still good, but I intend to put EBC YS brake pads along with new rotors. (whenever I decide to pop the hubs apart for reseal, etc)
Currently as the truck runs, the brakes work great on 33" tires and 16" wheels.

Mine is also a November 1989 built, 1990 FJ62.
Order your parts off of a "1989" when searching online.

Most sites can't differentiate between a 1990 FJ62 and 1990 FJ80.
 
Yep, we’re in Orlando and happy to discuss and supply all options, including the lift and associated parts as well.
We’ve done basically every combo to 60’s/62’s

1) yes to the master. No to the booster. FJ-62 booster is a good unit. Better than the 60. Comparable to the 96 4-runner.
2) '89 and 90' is the same production in US models.
3) Aisin hubs are tough, can be rebuilt, and are used with the FROR brake upgrade.

Answers to the questions you didn't ask are:
1) Bigger brake disks require bigger wheel diameter so you'll need to change wheels, which will cause back spacing issues that will require rear axle modifications, the simplest being bolt on wheel spacers.
2) Good functioning OEM brakes on a 62 are sufficient for 31" tires on even a moderately heavy loaded Cruiser. I run 32" without issue but wouldn't want to tow heavy.
3) Here's a detailed write up about what you're planning to do:

Thread 'Brake Upgrade - The Tundra Mod'

Hello All,

Here are some specifics for performing the Front Range Off Road (FROR) Tundra brake mod on the front axle of a 60 Series Land Cruiser. This combination of master/caliper seems perfectly balanced with pedal travel, feel, and response. Braking performance is a huge improvement over OEM and capable of stopping heavy loads with oversized tires. Toyota has been (and still is) using these components for 18 years. FROR's adaptor has also been in service for many years. I sincerely wish there were more threads to hold the caliper bolts but have not read about any failures.

Thanks guys, love the knowledge of this place. @60Works - so what I think I'm understanding from your original thread is that the Tundra 05 brake upgrade does extend the hub width about 1.5 inches on each side. This would explain why you were able to put on the Method 16" wheels with a > 4" backspace on the front but required you put spacers in the rear with the same wheels? I saw that further down the post. Interestingly, I was looking at very similar Method wheels and was hoping to avoid spacers.

I've heard great things about @cruisermatt - I will definitely call them for advice.

Correct, mostly.

1 5/8" outboard relocation per side.
I used 17" x 8.5" wheels with 4 1/4" BS.
OEM wheels for the JDM with fender flares was 2 3/8"

4.25 - 2.375 = 1.875 inboard change in BS from wheel
1.625 outboard change in hub
1.875 - 1.625 = .25 inboard BS
wheel is 2" wider giving a 1.75" wider stance

Overall braking is vastly improved. If I were to do it again, I'd use the even larger 4Runner rotors. And would use OEM Toyota calipers. The Powerstop have already seized a piston. This solves the problem of finding new wheels that will fit, of changing rotors easily, and the inadequacy of the OEM brakes with larger tire sizes. An 80 rear axle conversion solves the problem of wheel spacers. On my install, the 80 axle appears to have induced annoying torque steer (still working that issue) because of the displaced 3rd member.
