just 2 quick questions.

on this car, i noticed that when i brake hard enough for the abs to kick in, it feels like the brakes stop the car longer than i want it to. for example, if i were to slam on my brakes, and then abs kicks in, and while abs is still pumping, and i let go of the brake pedal, the car will STILL brake and abs still pumping for about half a second after i let go of the brake pedal. its not really a concern for me because when other than that my brakes work completely fine.

does this car have some kind of technology that brakes for u so u wont roll back on hills while in Drive? i noticed that with this car vs. my other cars that on a hill i dont roll back much(if at all), whereas on the same hill with another car i would roll back.

 

are you 6MT?

 

no, 5at

btw i said "while in Drive" lol

 

maybe my problem is that i dont have a 6mt, lol. jk

 

Well, I know that the 6MT's have hill start assist, which holds the brakes on a hill.

*edit
I think....Cannot find any literature on it.

 

^ I didn't know that. How does that work?

I'm not really sure what you're asking but auto cars will roll back if you're not on the brakes IF the hill is somewhat more steep than a "normal" hill. If that makes sense. I'm assuming there's only so much load the gears pushing the car forward, in drive, can take before the weight of the car + gravity wins and pulls the car to roll backwards. It's just like when you're at a stop light on level ground and you let off the brake, the car will roll forward (in drive).

Also, it's normal for ABS to continue working for a moment when people try to pump the brakes. I think this is partly because it has been generally taught to drivers to pump the brakes if you're in an emergency braking situation. However, in an emergency braking situation with ABS, stomp the fucking pedal and don't let up until you're stopped or whatever danger is gone (deer crossing the road, etc).

 

I have noticed that my car does not roll back on hills when I come to complete stop as well ('08 5AT), but have not been on enough different hills to tell if the car is purposely holding it's position of just that the slope of the hill and the car sitting in "D" "match-up" so that it doesn't roll.

 

Again, there may be something on the car that keeps it from rolling back on the 5AT... but, generally, an auto car will roll back on a steep enough hill. Hopefully someone with a bit more knowledge on the 5AT can chime in here.

 

I've been in several cars that will apply the brakes if the clutch is pushed in and you're at a dead stop.

In many cars, the ECU will continue stopping the car for half a second or so after you let off. They consider this a feature, I consider it retarded. Apparently the average driver is considered so dumb by manufacturers that they can't decide when to let off the brakes for themselves so the car does it for you.

I hate this "technology". Just the other month when I had a chick pull out in front of me, I hit full ABS at 50mph and swerved at the last second. I let off the second I was around her for two reasons. Not wanting to get rear ended by people behind me and the rear end stepped slightly out of line and I wanted to straighten it out. It was a little scary when I let off the brakes but they stayed on for a while.

 

Discard my ignorance here but on a GM most of those stupid things in the ECU can be tuned out. Any way that can be done on these cars?

 

I don't think so (95% sure) - that started with 6MT in the 4G, 2010, iirc.

 

Traction control and stability control can be turned off. ABS can't and I'm pretty sure it's against the law for a manufacturer to give you the option. I've pulled the fuse to disable it for testing before.

 

well, maybe I didn't word that correctly.. not disabling the ABS all together but whatever it is that makes it stick after disengaging. I was just curious since it doesn't happen on other cars.

 

abs will ALWAYS result in longer stoping distances as the computer is constantly applying/releasing the brakes vs constant pressure. the best stopping distance is just before the tire starts to liquify at the contact patch (this is when it has max grip)

The TL has pretty good brakes and if you are getting the abs to kick in, you are either driving in inclimate conditons, there is a slick spot on the road, or you're doing it wrong and will be constantly replacing pads and rotors due to abuse...

 

I fully agree. I've measured stopping distances in the TL with ABS and with the fuse pulled and I can out stop it in perfect conditions by a considerable margin. The TL is the first car I've owned with ABS so I got very used to stopping hard without it. In a really bad situation I've found that modulating until you're down around 25-30mph and the letting them lock the rest of the way to 0mph is the quickest way to stop. It also means flat spotted tires but locking for that last little bit really cuts the stopping distances.

I had to laugh at some old videos of the magazines testing cars in the '60s. They didn't even try to modulate the brakes, they just stomped the pedal and let the tires lock up with the car going all over the place and sometimes spinning.

 

I agree, having to use the ABS in this car would have to be a life or death situation or something haha.. To have a problem stopping in this car (the 6MT w/ brembo), there has to be something wrong. When these brakes bite, they don't play around. In fact, the brakes are one of my favorite things about this car.
