Not to bash you more H.O.L. but my truck has front disc, rear drum and has ABS only on the rear (single sensor on the differential, both wheels must lock before ABS activates), many many many mid/late 80s to mid/late 90s American pickups had this setup.

In for examples. Most modern cars are 4-wheel disc, unless they’re super economy busters. Most modern cars also have ABS, as they reduce insurance costs and increase safety measurements. I have ABS on my 2007, with 2-wheel disc, but it falls into the economy car group mentioned above. I would say the opposite is true. MOST cars with 4-wheel discs have ABS, unless they are more than 10 years old. But more likely this is because many cars 10+ years ago didn’t have ABS at all.[/quote]
That was exactly what I said.

Neither the Trooper or the Miata are normal cars. One is a 4x4 and the other a sportscar.

In Australia we’ve had non-ABS 4 wheel disc brake cars since 1987…

ABS stops wheel lock-up so you can steer the car while hard braking. ABS actually makes the braking distance worse than a full lock-up as locked wheels provide more friction and stop the car quicker.
ABS trades off distance for control by allowing the driver to attempt to avoid the obstacle rather than hope they won’t hit it. You don’t need ABS to control disc brakes but you need disc brakes to run ABS.
The cars with drum rears has the ABS only working on the front of the car. [/quote]
I’m a mechanical engineer BE. Kinectic friction is lower than static friction. That is why when something is stopped it looks like it’s sticking more than when it’s moving.
A perfect ABS will make the car stop faster than no ABS. Because it keeps the wheel on static friction. When wheels are locked they are sliding so the friction rate is the kinectic friction rate. The same thing for the brake pads. That is why when you lock the wheels with a certain force applied to the pads you have to get below that force to unlock the brakes.
So yes, in practice ABS can make the braking distance longer if it has low quality. But on modern cars no. ABS is generally better because it optimizes everything.
Also, you can adjust the brake force through the brake fluid itself. I believe this is how the brake bias systems in race car works. But that isn’t ingame and in production cars they use the same pump for a bunch of models so they never fiddle with that.
Most times I use simple language. First because I’m not a native speaker and I don’t like to go into technical aspects using wrong terms. Second because I like to things simple to understand for everyone. But sometimes, specially on forums people are condescend.
Did I say only cars with disc all around use ABS? No. Did I say cars only start using all around discs after ABS? NO.
What I said was that the ratio of cars with all around discs and cars with drums inverted after ABS appeared. This is true for Europe as far as I know.
PS: I’m not upset. I’m happy my thread got so many replies.
