As I was standing in the garage having a cup of coffee this morning, I was thinking about my braking system. I thought to myself, wow, i wonder if there is an stand alone ABS system that I could put in here. That ran me down the other list of things that I want to do to my car and the $$$ associated with that. Oh well, I need the roll cage, motor, and ......

Front only abs would be nice. With an electric brakes booster that jumps the pressure to some thousand psi. Yeah!

Can a trained right foot pump one caliper at 10 times per second while applying steady pressure to the others? |

To further your journey into the ABS you may want to consider a system off of a BMW motorcycle. BMW bikes are what come to mind because I have two and am familiar, to a point, with thier system. Plus, if its on a bike it is probably small (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) , very protable (IMG:http://www.914world.com/bbs2/html/emoticons/smilie_pokal.gif) , and should not be too hard to find (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif)
FYI: many of the BMW bikes use the same calipers as other light sports cars, Brembo. My 1100RS has dual front, and a single rear caliper. It should be a good candidate for two wheel ABS. Who knows? (IMG:http://www.914world.com/bbs2/html/emoticons/confused24.gif) |

sounds like a great way to lock up your rear brakes (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) |

I've driven cars with ABS and it's highly overrated Gives the driver a false sense of safety... I don't need it, thank you very much |

I've only driven two cars with ABS, an early 90s Prelude and my wife's 2004 Subaru. The Prelude system was simply dangerous. I sailed right through an intersection with patchy ice because the ABS had such a slow cycling time that it was applying the brakes on the icy bits and releasing them on the bits without ice. Scary.
The Soob system is so passive that you really have to be aggressive to activate it. You can get some minor slip, but if you go really gonzo and slam on the brakes, you can just barely feel it kick in. However, the car has soft enough suspension that things get pretty hairy if you try to brake hard and turn, and not from wheel slip, but from wheels leaving the ground entirely. Anyone who really needs it should probably be taking the bus instead. ABS only the fronts, yeah, good idea... (IMG:http://www.914world.com/bbs2/html/emoticons/screwy.gif) |

ABS is a double edged sword..
I used to race with a guy that had an E30 (I think) M3.. Once the ABS sensor on one of his wheels failed. He promptly flat spotted his tires.. He had no idea how to modulate "regular " brakes. He came into the pits slammed his helmet down in a very melodramatic fashion and had a tantrum..Bill and I though it quite funny.. I always thought it pretty sad that some race drivers, just stand on the brakes and let the ABS modulate and slow the car..because cables and sensors do fail.. One should have the skills to deal with that. Proper braking technique takes some seat time. |

If a stand alone ABS system was available for a 914 at a reasonable price, I'd be on it like a chicken on a june bug. It's not likely to happen due to the variables involved along with the dangers of letting folks mess with it.....liability & all.

Humm...modulate 3 braking tires. ...or more precisely, tires that brake at differnent rates. I gotta work on that (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif)

JP when one sensor on the ABS system goes out.. the whole ABS is offline
ie if one ABS sensor fails, you dont still have three wheels with ABS.. you have zero wheels with ABS..at least on the early M3s If thats what your talkin about.. |

I have driven lots of cars with and without ABS. I can use both pretty effectively, but I hate those abs systems that deploy too early. I like the things you can do without a computer between you and the brake sometimes. However ABS is nice as you cant lock up a single wheel when surfaces are slicker than expected. You know which company has really impressed me with their ABS application? Mazda! They have perfected the ABS systems on the all new 2006 MX5 and RX8. They figured out how to give these two cars threshold braking all the way to where the wheels start to skid and then the system smoothly modulates without the typical pulsing associated with ABS equipped Porsches I have driven. The MX5 and RX8 offer better to equal stopping distances to the Honda S2000, Lotus Elise, Boxster, Enzo and lots of other expensive cars with much better (stickier and wider) tires and suspensions. |

Well, that puts a different spin on things. (NPI)
So he should have changed his braking points and modulated his brakes as soon as he realized his ABS was non functional, eh? Personally, I would have pulled off. Had I not realized that I had a problem, I would have braked at my usual point, flatspottted my tires, pulled off, & then been pissed. (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) What I can't discern is what your position on ABS would be. Better or worse than non? |

I like ABS, though none of my own race cars are ABS equiped, I drive enough, and instruct in enough cars that have ABS to form an opinion. I have had students that approach a corner, and just stand on the brake till the ABS is active..they just step off the brake..and they use the "brake till I feel the ABS technique" Ive had students that were totally lost when PSM was switched off... I embrace all the tech, but believe driver should learn to drive sans all the tech.. learn car control without the bells and whistles.. |

Ah, a true 914 guy. I believe you're right, but it's been forced on me. (IMG:http://www.914world.com/bbs2/html/emoticons/laugh.gif) |

I thought ABS was STOCK on my 914!!!
I can't get my brakes to lock up if my life depended on it! (IMG:http://www.914world.com/bbs2/html/emoticons/biggrin.gif) (after overhauling all 4 calipers, installing a 19mm overhauled master cylinder, I'm convinced the inside of the lines have corroded internally and I'm getting a ridiculous pressure drop.. I've bled the system 'til the cows came home and still no intended lockup.....) |

Personally in the NE snow belt, I love ABS...
It keeps me from fixing all my cars... I do train my kids on cars without it so they know how to drive without it...that is very important, because it does not work that well on ice...it actually makes the situation worse in some conditions... So, learn how to pump the brakes... But ABS is alot of fun the the snow... It really stops the car quick...versus the slide to a stop technique... Rich |
