Been having a lot of problems with the 13WE calipers and today I swapped them out for 13WL calipers. I used the Power Stop kit because it was about 1/2 the cost of new OEM calipers, rotors, and brake pads. Plenty of clearance with the old 13WE calipers and 16" 70 series wheels. After pulling the old calipers I found one seized piston on each. Braking had been with bad pulsing and vibration. That's now gone.

Power Stop kit came with new calipers, rotors, and pads. Bolted right up.

I had read somewhere that the 13WLs would work with 16" wheels with no interference and that's what I found. No issues once I had the 70 series wheels bolted up.

I've put at least 1500 miles on the Power Stop brakes and they're a big improvement over the old brakes, but then new is almost always better than old. They performed well last week in late afternoon New Orleans I-10 traffic. The real test will be how well the brakes hold up after 10, 20, 30k miles.

More testing to come later this week at SSS 2023 Events/Trails - SSS (Southern Swine Soirée) 2023 - Land Between the Lakes KY. Let’s go! - https://forum.ih8mud.com/threads/sss-southern-swine-soiree-2023-land-between-the-lakes-ky-lets-go.1314685/ to include highway miles, back road miles, and off road miles.

Will someone please verify that the interface between where the soft brake line and the caliper meet is acceptable in this photo, please? I purchased part #BRH02934 from Cruiser Teq for my '62 and the depth of the female threads on the caliper are shorter than the length of the male threads on the brake line as seen in this photo and I want to verify this is acceptable. I dug through the forums for a long time trying to find the answer and this photo is as close as I've gotten so thanks for letting me hijack your thread for a minute, @Godwin.

Thread hijack is ok.

The lines I'm using are OEM Toyota and I can't say how the BRH02934 from Cruiser Teq compare. I've been running this setup for ca. 4 1/2 years and a conservative 80k miles without issue. No leaks, good front brakes if all other components are in good condition, etc. The male end of the brake line is well seated in the caliper, so the exposed threads are a non-issue.

I also have similar soft line setup on a FJ60 and FJ40 also without problems.
 
Reworked the rear brakes today with fresh parking brakes shoes, rotor, and low mileage OEM calipers from @jfz80 . FF 80 series parking brakes are are set up different than semi-float 60 series.

I've had this axle in a lot of water, mud, launching boats and was surprised at the lack of dirt, silt, corrosion within the parking brake cavity of the brake rotor.

Do the 60 and 80 series parking brake setups just differ at the axle, or is the cable assembly "upstream" of where it connects to the axle different as well between the two series?
 
 
I have a 80 series cable in now. I think @wngrog made it work with a 60 cable. If I were doing it over I'd try the 60 cable first because of the extra length of the 80 cable; the extra length between the axle and parking brake handle.
 
Thursday afternoon, pulling up to the house, my brakes became very heavy. Dead brake booster. I've lost track of how many boosters I've swapped out over the past 20 years. The current one was an OEM 60 series that may have come from a '88 FJ62. Needing to fix this as quick as possible I ordered a FZJ80 booster from Rockauto, went with the Cardone rebuilt unit. Swapped in today and good to have easy to stomp brake pedal once again. Driving an overweight FJ60 with no booster is not fun. Push rod from booster to MC was preset at the factory. I checked it with booster rod setting tool and it was spot on.

We started using OEM 80 series boosters for our shop installs last year. Pricy but a buy-once type deal.
