Formula One cars have ABS brakes?

I see them lock there wheels up, so I'm guessing no.

Good guess! Next question?

Smart ***.

I want to know if someone knew for a fact.
------------------------------------


I see that Prototype/Open wheel / and toher race cars don't have a brake booster - vacuum assisted crap.

All I see is a pedal and a master cylinder or 2 do there units create such adequate force, for them to not need a brake boost and vacuum?

For ppl watching - these units

F1 cars used to run ABS, but they were banned a couple of years ago when Ecclestone started trying to cut costs by cutting technology. Went the same way as active suspension and Honda's trick front diff.

Can't vouch for the Prototype brake set-up. Never seen 'em up close.

Most driver aid's are banned now. Cost containment for the lesser teams, tighten up the racing for "the show", among other reasons usually cited.

2004 F1 Technical Regulations:

The familiar adage can be applied "...if the rules don't specifically say you can do it, don't..." Actually, scratch that "11.1.3" and "11.1.4" says you can't do it in a more general sense.

ARTICLE 11 : BRAKE SYSTEM
11.1 Brake circuits and pressure distribution :
11.1.1 All cars must be equipped with only one brake system. This system must comprise solely of two separate
hydraulic circuits operated by one pedal, one circuit operating on the two front wheels and the other on the
two rear wheels. This system must be designed so that if a failure occurs in one circuit the pedal will still
operate the brakes in the other.
11.1.2 The brake system must be designed in order that the force exerted on the brake pads within each circuit
are the same at all times.
11.1.3 Any powered device which is capable of altering the configuration or affecting the performance of any part
of the brake system is forbidden.
11.1.4 Any change to, or modulation of, the brake system whilst the car is moving must be made by the drivers
direct physical input, may not be pre-set and must be under his complete control at all times.
11.2 Brake calipers :
11.2.1 All brake calipers must be made from aluminium materials with a modulus of elasticity no greater than
80Gpa.
11.2.2 No more than two attachments may be used to secure each brake caliper to the car.
11.2.3 No more than one caliper, with a maximum of six pistons, is permitted on each wheel.
11.2.4 The section of each caliper piston must be circular.
11.3 Brake discs :
11.3.1 No more than one brake disc is permitted on each wheel.
11.3.2 All discs must have a maximum thickness of 28mm and a maximum outside diameter of 278mm.
11.3.3 No more than two brake pads are permitted on each wheel.
11.4 Air ducts :
Air ducts for the purpose of cooling the front and rear brakes shall not protrude beyond :
- a plane parallel to the ground situated at a distance of 160mm above the horizontal centre line of the
wheel ;
- a plane parallel to the ground situated at a distance of 160mm below the horizontal centre line of the
wheel ;
- a vertical plane parallel to the inner face of the wheel rim and displaced from it by 120mm toward the
centre line of the car.
Furthermore, when viewed from the side the ducts must not protrude forwards beyond the periphery of the
tyre or backwards beyond the wheel rim.
11.5 Brake pressure modulation :
11.5.1 No braking system may be designed to prevent wheels from locking when the driver applies pressure to
the brake pedal.
11.5.2 No braking system may be designed to increase the pressure in the brake calipers above that achievable
by the driver applying pressure to the pedal under static conditions.
11.6 Liquid cooling :
Liquid cooling of the brakes is forbidden.

BAR is using their new active torque transfer system at monza today durring practice, they took the electronic control out of it so it'd be legal. It didn't appear to help them very much.

Yeah, I saw that. Looks like Jense's contract negotiations are affecting his concentration. He hasn't been on the steamroller he was earlier this season.

You really think that's the reason?

More like Mclaren and Williams seemingly getting their act together.

I think Jensen isn't into racing, and won't be for the rest of the year. He's prob just living out the rest of the season. And all the praise going to Sato doesn't help much. Kind of like Montoya at the post-qualifying-press-thingie, he just didn't care about the car or the team. Just my thoughts

jenson has always had a problem w/ concentrating on racing. he seemed (this year) to finally have gotten over his starstruck-ness, and now he's got other things on his mind. This is by no means the sole reason for his being "off the steamroller" but it does play a signifigant part in it.

Anyone see the race at Monza? Some of those drivers sure could have used ABS for those first few laps in the wet.

I almost cried when Raikkonen went out with ANOTHER mechanical faliure--I think he would have been on the podium. Does anyone know what happened to his car?

And to Honda for being 2nd in the Manufacturers points.
