Unless the diameter of the master cyl piston is different, I don't see why it would need to be different. There's the same number of line outputs, one front, one rear.

A bigger master cylinder would help with threshold braking (non-abs way of stopping without crashing). It would require more effort to lock the brakes, and give a more detailed pedal feel.

This makes me wonder if any of the other toyotas used a bigger master cylinder that would fit the A70. Gonna have to look that one up sometime.

lift off the some brake front tires bite then turn crazy how that works

Then you're no longer braking to the vehicle's full ability. Another situation is one side of the car is on wet pavement and the other is on dry.

Nash, No offense, but your (or anyone elses) argument of stopping a car quicker without ABS goes out the window as ABS Is not designed to yield shorter stopping distances. It actually is known to increase straight line stopping distance when utilized.

However you cannot stop in the same distance, in control, around an obstacle, in a panic situation. Not happening, period.

Maybe on a track modulation is better then ABS around a expected and known turn in a normal state of mind, but not in the real world when a baby stroller is pushed into your lane 30 feet in front of you at 60mph with a narrow shoulder and a parked car 10 feet after that.

I hope im never in that situation, but if i am i know i (and anyone else) would be better off with ABS.

Depends, if you lock up the wheels you get longer stopping distances than if you don't lock up.

You have a finite amount of traction. Acceleration, steering, and braking all take traction to perform, and if you max it in any of them you stop the others. If you exceed traction, you slide and lose control.

Still don't believe me? Here, watch:

ABS controls 3 seperat channels in the MKIII. Unless you have 3 brake pedals and more than 2 legs, it is 100% impossible to do what it does. This is why ABS is used on race cars...

yes they do. the 1990 ish v6 4 runner. the line outputs are in a diff spot, so you have to re bend the lines. ill have to check but im 90% certain its a direct bolt on to the booster, ill measure one up at the junkyard tommorow


they also had a real goofy abs system that used the power steering pump, thankfully its only a rear abs sytem.

yes I know and I never want to be there ether, will abs save what ever's in front of my car hard to say but are the chances better yes shock does crazy things when shit just jump out front of you

but i tend to have my shit glued on the road at all times and hope this will never happen to me


plus most times shit jumps out in front of you are in 30,40 and 50 km zones

when I drive to have fun it can be bit of annoyance some times the 2way lsd does not like it ether
at the track as well it can be a pain when i want to transfer weight fast

and heat soaked brakes and abs mix is down right ugly





if the supra had smarter 4 channel and bigger brakes I most likly have ketp it


fro when i get bigger brake sooni just going to run will wood setup or run prop vavles to help with weening the hit of the brakes



and in snow i find the abs system to not help much i rather plow and build up mond of snow to help me build a wedge and repete tell you regain control




this is why i don't like the mk3 ABS system in my car in it's current state




and all you need is the stock n/a lines from the front half of the car thats it, every thing els is the same


the 90 to 95 and 89 to 94 4runner/v6 truck have the bigger master and it is plug and play
but there is no reson to upgrade teh master the stock one does the job just fine

"In formula 1, ABS was banned in 1993 after being used most successfully, along with many other driving aids, like traction control, launch control, active suspension and so on, in the 1992 and 1993 seasons. It was classified as an electronic driver aid, preventing the wheels from locking up and eliminating the driver's skill from the process of braking."

If they could use it, they would, because it allows them to brake harder and deeper into a turn. The only reason not to use ABS is if the rules say you can't!

Internals are different and front/rear is swapped. Will it work? Yes, but it might mess with bias or a failsafe.
