- |I've just seen a mechanical ABS retrofit. Its called "ABS-TRAX" and is
- |supposed to be derived from aircraft systems. Have you heard of it, and if
- |so, any data-points or anecdotes?
- |
- |The system consists of a small pressurised chamber which fastens (one per
- |brake circuit) onto the master cylinder output, somewhat like a reserviour.
- |The chamber contains a pressurised Nitrogen chamber and diagphram; when the
- |brake fluid hits a pre-set pressure (supposed to be within 5-10% of lockup),
- |a valve will actuate to relieve the pressure and keep the wheels on the
- |threshold of skidding (somewhat similar to threshold braking). Under normal
- |braking, it is supposed to not activate.
- |
- |There is no speed sensor like the electronic versions. Since this device
- |works on a principle similar to threshold braking (I think), it appears to
- |be better than electronic ABS, no?
- |
- |The sales guy could not tell me how/what was used to determine the threshold
- |nor the method of pressure relief.
- |
- |This system is supposed to in use on aircraft, and is supposed to reduce
- |braking distances by up to 30%. Its also supposed to be DOT certified (for
- |what its worth). The company claims to have sold 15000 units in US alone.
- |
- |
- |Does anyone have any experience with this? Does this system sound viable?
- |Is this really used in aircraft? Should I part with good money for this?
- |
- |(price is approx US$620, incl installation).
- |
- |comments/suggestions welcome.
