Simultaneous Application of Gas and Brake Pedals

I didn't mean it like that... I do have all new, parts store belts and
hoses on the car, I just didn't need to replace the original brake
linings as they appeared to be essentially unworn. I have, however,
heard complaints about the unboosted versions of my car being hard to
stop many times - I think I'm about the only person I know still
driving a drum-braked Stude without a booster, and that's the only
logical explanation I can come up with - everyone else has probably
replaced their linings at least once by now.

feel.

So how do you feel about Hydrovacs? Don't hold back, keeping your
feelings bottled up isn't good for you

nate

 

Yes, you keep laughing, I am still driving one. It is
forty three years old, and I still hop in and drive it
whenever I need to. It has been the most reliable
vehicle I have owned (and I have owned alot) in
the twenty two years since I got the first one.

Nope, the difference is in how they are sourced and installed
and how parts are cataloged for them. If you need an alternator
for your BMW you may be asked if it is a Bosch unit or a Marshal
because the alternator was purchased seperately and installed by BMW,
not manufatured by them.

If you have a honda, and you need a cap and rotor, you will need to know
who made your distributor, TEC or Hitachi, or perhaps Mitsuba.
just calling it a "Honda distributor" will make the parts counter guy
laugh, but will not get you the part

Not always, and specifically not in automotive applications

Nope, not always

(which is the goal most of the time. No different I guess in

You must be an engineer, lots of theory, no practical
application as applies to automotive.

I know that some of the people who plst are engineers,
but I have seen to much of this "really informed mis-information"
from that particular class in my sixteen years of selling
auto parts in Seattle (Boeing country) to miss making the
observation.

No opinion *yet*, haven't driven one.

 

c'mon down, you can drive my old '56 (bring lots of ATF)

I'd say it the other way around. Disk brakes need larger piston area
because they don't have the self-energizing capability.

I worked for a "corn binder" dealer in the early seventies, and my
impression then and now, was "under engineered and over built". They
were dirt simple, rock solid, butt ugly, almost indestructible, crude,
purpose built machinery.
They were elegent in their simplicity, and if the ultimate test of
engineering is not that nothing more can be added, but rather that
nothing more can be removed, then you could say they were well
engineered.

 

But in so doing, as Nate has pointed out, other things are traded off
and design safety margins (for pedal travel, pedal hi point, pedal low
point, etc.) are more compromised.

And the larger caliper piston area multiplies the required pedal travel,
but what saves the disc brakes from that effect is that the
caliper/piston/pads relax (away from the rotor) a lot less than the
shoes relax away from the drum when brakes are off, so that part turns
out to be about a wash.

Because the non-boosted system is designed for the differences.

Fair enough.

For a sports car, that would be *under* engineered, for
a truck expected to stand up to poor treatment, poor
maintinence, poor fuel, etc.. and keep running and running
I think that is a pretty good definition of what the target
should be, IMHO.

No, you will ask for an alternator to fit a sept 1994 production (or a
an "N" code) Honda Civic SE, or whatever, and IF more than one
manufacturer was used on that model and production date, the
counterman will ask which one it is, as the alternator, or
distributor, or starter or whatever is built by these several
different companies SPECIFICALLY to HONDA specs. The mounting ear
location may fit ONLY a certain Honda engine, and nothing else.

And for wheels, it is just as correct to refer to say, a 4 boltX 98mm
13X5" J3 rim with negative offset as to say it is a Fiat 128L rim.
(numbets may be off a bit, but 4X98 it is. Or Chrysler 5X100mm, or GM
5X115, or Ford/AMC/Mopar 5X4.5?

DOes not matter what the original application was if it has the right
bolt pattern, size, and offset.

 

There is ONE reason why disk brakes generally are more likely to
require a booster, and it relates directly to increased pedal motion.
Put simply, a disk brake caliper has a much larger piston than a wheel
cyl, and therefore it takes more fluid to move the pads. To move that
volume of fluid and produce the required pressure without excessive
pedal travel on an undeslung pedal design is not impossible - but
using a booster makes it significantly easier.

 

Not true, alternators may be used on BMW, or Volvo, or Volkswagon
that are the same part number.

Distributor caps that fit a Subaru may also be found on a Toyota.

Don't take my word for it (since I have only been ASE certified P2
for ten freekin' years) open up a buyers guide for Standard,Niehoff,
any tune up parts manufacterer. Then look in the back of a buyers guide for
rotating electrical (alternators & starters) and see what the application
listings are by part number.

A little knowledge.....


Bernard

 

I understand that.

I understand that.

I understand that.

Yes - frequently. Chevrolet wheel, Chrysler transmission, etc., etc., etc.

To hear you and Daniel, I get the impression that if someone posted a
statement like "Hi guys. I hear that Chrysler transmissions of the
early and mid 90's were trouble-prone" that you would be totally puzzled
about what the person meant by "Chrysler transmissions", when everybody
else would know exactly what was meant.

It's done all the time. Again, Chevrolet wheels, Chrysler
transmissions, etc., etc., etc.

You missed it on this one.

I knew enough even as a teenager in the sixties to know that when a
mecahnic told me that my Travelall had an AMC transmission in it that it
had the same transmission that was used in AMC vehicles. Sounds pretty
practical to me.

Oh - so other "classes" of people are immune from that. B.S.

So you're saying I should use pounds as a unit of torque? What's
practical about that?

The stark reality just hit me that you took my comment about the reason
for the difference in referencing types of wheels and alternators and
transmissions being because wheels are round and alternators and
transmissions are irregularly shaped as a serious assertion on my part.

LOL! Please tell me that isn't the case.

Begin quote

Dana Fisher -- 1/10/2000, 3:33 p.m.


The T-409 automatic transmission is a heavy duty cast iron unit made by
Borg-Warner. AMC called it a flash-o-matic. The T 39 and T 49 are the same
just not as heavy duty in the servo and planetary area. This style goes way
back to the 50's with IHC T26 T28. They got better over the years but were
quite heavy and I think Warner quit making them in 1971 or there abouts--IH
being about the only user. Ford also used this design but used linkage for
the kick-down not electrical [ Ford Model FMX ]. I think Japan even copied
it but shrunk the mold somewhat.

end quote

Made by borg warner, they are an independant
company that makes MANY transmissions for MANY
auto and truck manufacturers. Apparently it was also purchased
by AMC, but was, in fact not an AMC trans. Small point
perhaps, but laziness annoys some people.

Nope, just saying you seemed like a particularly bad
type of nut-job that I had run into before.

See? that sentance makes absolutely NO sense.

 

Nope, just heard misinformation about stuff I do
each and every day.

 

Examples of the misinformation would be...?

Yes - I know your type too, if you want to start stereotyping people -
the guy, who for whatever reason did not get a college education, and
stupidly feels inferior to those who did and so looks for reasons to cut
those whom he feels inferior to down to try to feel better about himself.

I'm still amazed that all of this is over a simple statement that I was
told that the vehicle I drove as a teenager had an "AMC transmission".
While, for non-professional conversation, it was perfectly adequate for
conveying what was meant, you are looking at it as an opportunity to
nit-pic the precise meaning of. You don't really believe that you don't
know what someone means when they say an early- or mid-90's Chrysler
trasnmission? I suppose you have some convuluted explanation why that
isn't the same as a statement of that day of saying the vehicle used an
AMC transmission? Yes - I also know your type very well.

I was just trying to find examples of what you were nebulously claiming
about impracticalities in what I had said previously that put me into
your stereotypical view of engineers. The only thing I could find that
you might have been referring to was the example I had given of
technical illiterates who express torque values in pounds. You seem to
fit the category. So how does it feel to be stereotyped? Are you one
of those guys who tries to sell your customers SilverStar bulbs because
they are "brighter".
