Builds Project Snowball ❄️ 85 FJ60 Cummins 4BT/ HX-30 SUPER/ NV4500/ SOA (1 Viewer)

Yeah, the Racer65 one accepts the stock M10 brake line fittings. Makes it a cleaner install.

Just finished my FZJ80 rear axle swap last year. I ran custom brake lines using CuNi Alloy with the usual M10x1.0 fittings. Since I was doing all custom rear axle lines I put stainless gravel guard over the lines for protection.

The FZJ80 master cylinder has 2lb residual valves front and rear to keep the pads close to the rotors. If I would have figured this out a few weeks back I would have bought that over the 93 T100 MC which was cheaper. I plan on tearing out my LSPV and running the manual one mentioned.

@Randy88FJ62 dp you have pictures of your setup? I’m going to be doing this same setup that Hojack is doing, it’s nice to follow along.

 

[Randy88FJ62]

I checked the build thread and it's pretty weak on tech info. pm me this evening after 4pm PST and I can text you a bunch of pictures.

Did you go with an 80s master cylinder?

 

[Randy88FJ62]

I wish I would have if I had known better at the time a few weeks ago since it has the residual valves built in. I am running a 93 T100 MC and booster.

 

[Racer65]

@Racer65 on mud sells a nice manual valve

Or just use a 60 series valve.

Following along. This my next major project. (SOA & all that goes with it)

 

[Randy88FJ62]

yukon,
I have a spare semi-float rear axle sans diff already setup for SOA that no one wants for a very good deal. I visit mammoth area often in winter.

Thanksgiving I'll be passing through carson going north as well.

I have a fj60 master with a rear disc 80 axle on my fj40, with a manual adjustable proportioning valve I really like the feel of the brakes.

 

[Hojack]

Question: The adjustable proportioning valve regulates how responsive the brakes are?

 

[cruisermatt]

No, the adjustable valve goes in the rear brake circuit and cuts off a percentage of fluid flow to the rear brakes.

I wouldn’t run the factory 60 valve with the rear discs. You want to be able to adjust it.

 

[Hojack]

Is it a set and test drive then adjust if needed?

 

[cruisermatt]

Yes

 

[Hojack]

There is this one which looks non adjustable.

Or this one which only says FJ40.

 

[Hojack]

Need some help with these proportioning valves. Need to be able to adjust but it says FJ40.

 

[Hojack]

@Racer65 says the FJ40 one is two port for rear brakes only. Isn’t this what I want?

 

[cruisermatt]

Yep. Looks like a nice piece too.

 

[Hojack]

Thanks @cruisermatt
Any other parts would be appreciated. Got the pole barn bay cleaned out yesterday for next weekend. Was planning on some cutting but was on call for work and had 2 emergency no water calls.

 

[Hojack]

Meet up with @Rustic76 and finally picked up his 4plus bumper. Got to tour his awesome cruiser collection. Thanks a lot buddy for the great deal on this. Hopefully we can go snow wheeling soon.
