If you guys have ever had to make an emergency stop, to avoid getting into an accident, do you guys hear loud thuds?

Traffic stopped all of a sudden and so I hit my brakes expectingto rear end the lady in front of me, but my car was able to stop in time. While I was coming to a stop I just heard two thuds.
Is that normal?

is it more like a clicking than a thud? if so abs....

Babnik

The VSA detects when the driver attempts an emergency stop and applies additional pressure on the brakes. Not sure if this would cause a thud.

ABS engaging sounds almost like a metallic creaking sound.

can you provide that quote from the online owner book?
had not heard of vsa increasing the requested brake pressure

normally ABS will pulse the brake pedal rapidly as it applies and releases the offending wheel brake...in order to keep the wheels turning-- not skidding
Its design intent was Stomp and Steer, allowing you to hit the brakes and turn the wheel to avoid the accident.
On straight line stopping it modulates the brake pressure to a caliper or 2 only when the wheel speeds get out of synch

To see how it works and feels, throw some water on the street and drive thru it with one side of the car in the water- the other 2 wheels dry
Apply the brakes full- as hard as possible- 2 footed, as you go thru the water and tires lose traction, the abs will pump/pulse- the car should stop straight ahead with hands off the wheel (a description not a recommendation)
Newer cars have even more computor interaction

No Hal- this is all the brakes I want~

He's right about the car detecting an emergency stop.
It calculates how fast you press the pedal/how quickly you apply pressure. When it detects emergency braking it will apply full braking force.

But no, it was not a click it was definately thuds.

well, sometimes i hear strange noises when i brake. NOT ABS, it sounds like im driving over rocks lol.

Don't know what the "thud" is though. You didn't have something in the trunk or center console did you?

pnoi521

No. I've heard it before when traffic on the freewaysuddenly stopped.
The thud sounds as if I actually hit the car or like thenose of the car hit the ground, which I doubt.

just throwing it out there, do you have tranny issues? When my old cl's tranny was on the way out,in a hard brake situation the tranny couldn't downshift fast enough and finally thumped into 1st or whatever gear. The whole car jumped like I hit something........

mayb it was people crashing around/behind you? idk jus an idea...

wow you gen3 have all sorts of cool tricks! thanks bearcat

So, its not actually an emergency braking system that activates, its IF you go sudden pressure then partial release, as if you were acting on feedback from the tires and trying to keep max braking while loosing traction..
the computer goes to ABS and pulses as needed- thinking you are in danger

Heard the car will brake one wheel if you get into a corner too hot or try something like a 4 lane change at speed on the ice~ also has throttle limiter
Technology! I have to actually drive my 01

As for brake noise- noise while braking - get to a shop for inspection
Could be something like sway bar end link or other part loose/broken

Teddybear

its abs. my TL "thuds". i hear it a lot when i drive in snow.

H-town_Ryda_06

my car does that too but i know mine is from my sub box sliding around.. haha.. do you have anything in your car that would slide forward during hard stops?

Tripnbeats

id think its possible to rip an OEM motor mount or tranny mount if going a decent speed and u smash the brakes and jerk to avoid an accident.

pnoi521

I hope not!
And to the other guy nope, nothing that would roll around and make a thud.

01tl4tl

time to put in on ramps or stands and look under for anything loose

pnoi521

ahahaha I like your quote
