I ask because the Expedition failed Saturday morning because the guy set the parking brake, started the truck, put it in gear, stepped on the gas enough to bring the RPM’s up to 1000 and the truck moved. According to him that = fail…
Now, this is a full sized SUV with low gears and a boatload of torque down low in the RPM range. The parking brake was definitely working, and capable of holding the truck on an incline, but that little drum brake inside the rear disc put on there just for a parking brake was not able to hold back 5.4 liters of american muscle.
So, I tore the brake system apart, cleaned everything, re-greased the parking brake mechanism and fiddled with the stupid adjustment wheel until the brakes were just barely dragging. Drove down my street at about 15mph, put the truck in neutral, and stomped on the parking brake. SCREEEEEECCCH!!!.. two black lines in front of my house. Put the truck in drive and it held to about 1500 rpm.
The wife takes the truck back on Sunday and it passes, but the guy still said it wasn’t as good as it should be. :bloated:
So I ask, how strong should a stupid little parking brake really be?
This was the quick lube place at Main and Youngs BTW.
LOL; Firestone on Dick/George Urban didn’t even check the one on my Blazer; they “failed” me because the yellow corner light bulbs were out!!! I tore all the parking brake crap off my truck because they were garbage and rusted to the point of crumbling.
i got failed once for a fog light being out… i had to READ the posted on the wall to the pep boys idiot who inspected it, which clearly state accessory headlights were NOT a failure point…
only reason i was tehre was to get a 24hr turnaround for a ticket
:lol: That’s the test for a commercial vehicle. Doesn’t specify rpm.
Parking Brake Check
With the parking brake engaged (trailer brakes released on combination vehicles), check that
the parking brake will hold vehicle by gently trying to pull forward with parking brake on.
Up until this point I’ve always had great luck with quicklube inspections. I don’t have a relationship with any shop since I do my own repairs and I find quick lube’s lack of repair facilities removes their motivation of failing things just to make some money on unneeded repairs.
And as I said in the other thread, I’m not looking for a “just pass it” shop. If there is something wrong that I missed I legitimately want to know, but this seemed a little excessive on the parking brake requirements.
i was told once that if the brake is on the car should not move at all … but i was under the understanding most cars will move in reverse with the brake on
he is a fucking idiot.you are not supposed to bring rpms up that high if that was the case they would have alot more failures. oil change shop inspectors are the cockiest dumbest people ever.
That’s what I was thinking. It’s so random if you start getting on the gas. Some Honda with 5 ft/lbs of torque at 1000 rpm is a lot different than some HD diesel that is making 400 ft/lbs at 1000 rpm.
Now i haven’t done a car inspection since november so they might have amended something new, but i believe you can not fail for fog lights even if they are oem. the only way you can fail for a fog light is if it comes on with and only with the headlight switch. if it has it’s own auxiliary switch like almost all car manufacturers(sp?) then you can’t fail for it.
Jay it has to hold under light load, it does not specifiy rpm. If the fog light work off a sep. switch they are not part of inspection. that and corner lamps are not part of inspection only turn signals and parking lights, unless the vehicle is 80" wide (tractor trailers).
So basically this tech has an incorrect view of “light load”. I hate ambiguous laws. If the best you can come up with is “light load” don’t even make it a requirement.
Ha I’ve never had an Ebrake checked on an auto car.
As long as I’ve had vehicles inspected, they look, if its there its there.
hahaha
hell most of the cars, if they pulled it it wouldnt release.
BTW: you really dont want to grease a brake cable these days. Most are lined with plastic and when you grease it with a petroleum based product it tends to swell the plastic and causes it to stick more
i was going to say that… but then i thought… wait JayS knows that b/c he knows everything. BTW if you use the parking brake more then once a year it will adjust on its own.
