Brake master cylinder differences - Current thread?

[cruiseroutfit]

I searched, I promise!

Is there a thread that details the differences between 80 Series (and non-80 of the same design) brake master cylinders such as the 47201-60540, 47201-60550, 47201-60551, etc? We have a dozen AISIN and OE cylinders that are all the same aluminum body, single reservoir design and each has something slightly different than the next. The US application stuff we have nailed down tight and the non-US is easy enough to look up via the EPC but I'm considering laying them all out side by side and making a chart of the differences. Might not be as valuable to US 80 owners but those with JDM imports and more often older Land Cruisers (4x/5x/6x/7x) looking for a brake master upgrade. Figured I'd search around first. Any thread hints before I start from scratch?

For reference, this is the cylinder type I'm referring to...

The non ABS ones have residual valve for the rear drum brakes? The early reservoir has the level valve built in, the later is in the cap. I prefer the cap type, easier to change when they become wonky.

I need to adapt a larger mc... any experience with that?

Some T100s have a 1-1/16" master.

Love to see the chart when you have it; interested in FZJ80 options.

Working on it in between calls today, I've got 11 cylinders on the list so far.

 

[nukegoat]

Anything like 1.375 or so?

What is the difference between these 2 i have a euro spec 3Fe FJ80 and have gone through 2 master cylinders in less than 50000 miles could this be why im buying the wrong one?

probably abs and non abs is the difference in the p/n

Great question. Not by my notes now but both are non-ABS. I plan to expand my chart to have bore diameters, residual valves if present, fluid level indicator location, port location, etc.

Trying to understand if this means we have more options on our rigs. Can more than one Master Cylinder go on a truck of a certain type? For example, could an US Spec 96-97 80 series, which has ABS, use a non-ABS Master Cylinder if it had its ABS system deleted? Is one type of Master Cylinder better/stronger/more robust than another?

Thx!

95 also has ABS.

 

[DirtaddictLC80]

95 also has ABS.

Thx I wasn't sure if ABS was phased in over the 1995 year or if all of them had it.

Good point. I've seen it said all 95s, but someone like Kurt has seen a lot more of them than I have and would know better. (So far as I know, all 95s also have airbags.)

Yup, exaaaaaactly why we are working on this, confirm specs and compatability for conversions!

ABS or not isn't significant to the master, the non ABS rigs have the semi-float/drum brake axle and that is significant. So if you want to upgrade to the drum axle, would want to run the non ABS master. All of them that I have played with are the same bore/stroke.

Are you running oversized calipers? If not, the bigger master would make pedal way more sensative

 

[Broski]

93 & 94 have ABS but no air bags. 91 & 92 no ABS no air bags

Most NA 93-94 have 4 wheel disk and ABS, some have rear drum and no ABS.

I'm running a 1 1/8 dodge w250 master with a skys off road adapter. I had to do some hole enlarging but everything else bolted up. That and you'd need adapters from m10x1.0 to the standard flare nuts it uses. Although, now I'm thinking of it, I'm not sure if it'd there'd be interference with the Toyota drivetrain or not. It's reservoir is much larger but I have a 6bt in place of OEM so dunno. For me, with tons, the 1 1/4 chevies were too big, I did not try a t100 1 1/16 but the 1" FJ master was too little. The 1 1/8 worked perfect. I could not get the 1 1/4 to lock up the brakes at all. 1.375 is hugeeeee Anyway... hope that helps some...
