RE: IML: Drums to Discs

["Ken Lang" <ken@xxxxxxxxxxx>]

Rob,

You are correct in that anti-lock brakes are more about control than
stopping distance.  An oversight on my part leaving that information out.

I do know that all my newer vehicles (since 1993) have had anti-lock brakes.
I can count on one hand the number of times they've kicked in and still have
fingers left over.

When I got my 67 Crown nearly 3 years ago, one of my first priorities was to
go through the brake system.  After giving the pads and shoes time to seat
in I went out on some deserted back roads to test the braking capability.
For me this is something I do with all my vehicles.  I hate learning about a
vehicles limitations while in a near panic situation.

I believe that pickups used to have rear anti-lock with the drums.  
Extremely hard to retrofit properly because the sensors all run through the 
computer and THE last thing you want to have a question mark on is your 
brakes.  I think some NASCAR cup cars used a rudimentary system (illegal) 
that senses pulsing in the line, but I never read much about them.  You 
could look into that.

I disagree that tests have found regular brakes superior.  There are some 
conditions where you CAN stop shorter without anti-lock, but it's not likely

and not as consistent. Those tests were done with trained race drivers.  
Anti-lock brakes aren't about shorter stopping distances, they are about 
control during braking.  I believe the newer systems are much superior to 
the older ones and you won't be outperforming today's systems.
