Line Locks

Had to front the cost on a ABS controller after doing a local install here. So my first source is my own personal experience to the tune of 750.00 bucks at the time (July 2006).

My investigation after the fact, netted numerous occurrences, with all sorts of versions of single solenoid set up. So I fought the manufacturer and eventually got them to reimburse me for my 750 bone outpay.

I'll PM you a few posts of the data so as to not infringe on Stangnet's other website reference rules. It's commonly known, I don't post stuff unless I whole heartedly know what I'm talking about. I think Heavy can vouch for that.

Its not that I don't believe you---its 1) never heard of this before 2) and I am curious as to what was the cause (or) why it happened and 3) how could it happen to some cars and not others? As stated earlier, I have had mine on for over a year and used quite often without problems---other buddies that I race with at the track also have the one solenoid set up with no problems. So I am curious about the root cause.

TMI did the research and published a memo back in early 06. I'll forward you a copy of it. Rich Goodrow an s197 specialist and a technical specialist with TMI worked the testing. I spoke with him directly numerous times. I thought they outlaid something in the ballpark of 16 or 17k in testing.. Don't quote me on that, drawing from memory here, but it was a large multi K number.

Basically, part of the problem is that the single solenoid is unforgiving in those drivers that are creative in it's use.. and for that matter fast at making adjustements on the fly.. My understanding is these people back wash (rush backing of fluid) the Booster (vacuum back rush in regards to the booster) and ABS controller and it fails partially or entirely.

There was another example of full failure on what I thought was nearly a 100% basis (again drawing from memory) when the single solenoid is engaged, and the user stayed mashing the pedal, once the lock was released, inherently so was the pedal and it appeared as though a double release occured. Backwash again occured and tossed the ABS light intermittantly, in some cases it was a constant, and in others the ABS was gone altogether.

So there are some specifics and an abbreviated list of what I recall from Rich's document. Apparently location of the solenoids right off the caliper and the use of duals is far more forgiving to all components of the braking system.

I could se why the solenoids would interfere with if they are piped in before the ABS and since they have there own seperate lines then I see the need for duals. I dont have ABS so a single would be sufficient.
