I can't figure out why they want to test it with almost 75 HORSE POWER pulling or pushing on this thing. Do they have any idea how a many horses it takes to make 75 horse power? 75 Horses could pull one of these down the road with all the wheels locked up tight. When is a "parking brake" ever going to actually need to hold back 75 horse power??? lol

I wish I could be faced with this... This would become a legal issue. I am in Az and they still tend to lean more towards common sense with the crap other states come up with and reject them as impractical and ignorant. Some politician put his good for nothing nephew though school and then put him in a position to write such nonsense as this even though he was asleep through all of his physics classes.

Hey bugout4x4, why go legal unless someone got hurt? Luckily that hasn't happened here. Annoyed, yes, but no injury and they are acting in good faith. You get more bees with honey, if you know what I mean...

Check it out
This is swee-eet!
Tom,
Below is your UPS tracking number. I had to send UPS ground due to the rotors but you should have it by end of day Saturday. I verified the shoes are correct and also fixed the steel for you so the adjuster will fit right out of the box. If you have any other questions or concerns please let me know and I will help any way I can.
UPS Tracking number 1Z2xxxxxxxxxxxxx
Thank you,

These guys are bending over backwards to please me! Good 'ol American folks doing it the American way!
Stay well my boys, keep the shiny side up,
Tom

Same thing with Propane cans and OPD devises. and the three handed gas cans. It was all about money and an attempt to help out a nephew who happens to own a brass foundry make some money.
On it's face it is a lesson in non-physics... On the ranch... We used to pull start engines that had been seized from sitting and the cylinders got rusted up with only two or three horses, REAL HORSES, 75 horses will pull a train.
Look if you fall for their justification good for you. But it does not make any sense and folks should not be loosing their jobs, be late on rent, or can't feed their kids because they can't drive to work because of this ignorant crap.
Some laws are just... Most are not...
It's outright extortion...

Didn't mean to go off like that... But until you have been to court MANY times over to protect everything you own over stuff like this, you would probably never understand. First prove an injury... I have lawyers retained to ask his very question every time it comes up.

It's okay, we all have our reasons. I guess I struck a nerve and I'm sorry for that. My courtroom experiences are few and I hope to keep it that way. My issue obviously pales by comparison but if I "walked a mile in your shoes" then I would probably get the bigger picture and would perhaps be less forgiving. For now my friend, stay well, have peace and keep the shiny side up.

Old fart with a wrench
My mechanic buddy looks at it this way. It's designed as a PARKING brake to keep the car from rolling when parked, NOT as an EMERGENCY brake! It would have to be much larger to stop a car from any normal driving speed. Therefore he is a little less worried about how well it works.
My 62 Chrysler convertible with the 413 only had a parking brake, no park lock in the transmission. It was only a 6x2" drum on the trans tailshaft. It HAD to work or you couldn't drive it and expect to find it after you parked it! Being a young kid at the time, I was stopped at a State Police road checkpoint they do sometimes right after inspections are due. The officer told me to set the parking brake and give it gas. I brought it up to 1000 rpm and he said "More!" Of course it moved. He said "Fix it! You can go." What an ***hole! I think he was trying to show his authority to the people behind me.

Parking Brake pass
Old Raybestos 807PG park brake shoes had out-of-spec ~0.5" deep actuator pocket.
New Raybestos 807PG park brake shoes, shown here with new actuators (which I really didn't need after-all), will have gap at bump-stop.
Side-by-side comparo of Raybestos 807PG park brake shoes new (left) vs. old (right). The deeper actuator pocket is what engineers found coming from their Mexican vendor.
New Raybestos 807PG park brake shoes have in-spec ~0.25" deep actuator pocket.
Received new replacement hardware (807 shoes and 76794 top-hat rotors) from Raybestos on Saturday, installed this morning (rainy Wednesday) and passed MA inspection this afternoon. Even with new hardware properly adjusted she began to roll at ~1250RPM. I was wrong about the 1500RPM requirement. The Massatwo****s parking/emergency brake requirement actually states that the brake must hold up-to something between 1200RPM-1300RPM and/or must stop the vehicle from 20MPH within 80 feet so I guess you could say we nailed it!

IDK if I posted this or not, but mine starts to creep at 1200. According to Chrysler, that's about 205 lb/ft of torque PLUS gear reduction.
