after i replace the brake pads and turn the retors. i feel that i need put more pressure on your brakes in order to stop the car and when i apply and hold even pressure on my brakes the car doesn't stop smoothly. what did i do wrong?

A few questions.

What type of transmission do you have? (this tells us which brakes you have)

Did you match your pads to your rotors?

What pads did you install?

Did you bed them in?

i have AT.

Did you match your pads to your rotors?
i bought the pads from the delaer.

What pads did you install?
oem pad

Did you bed them in?
sorry not sure what you mean bed them in.

Bedding in brakes is a process where you aggressively brake hard 8 to 10 times from 60 to 10 MPH in rapid succession. This causes the pads to "gas out", deposits pad material on the rotor surfaces, and "marries" the pads to the surfaces.

There is some argument as to whether or not this is necessary when going with OEM pads on new or newly turned rotors. If you decide not to bed your pads in, pay attention to any squealing that you may experience. Also, if they do not begin to stop the car as you have been accustomed to with the factory pads, then bedding in may be something to consider.

Spend some time searching websites on this topic as it relates to OEM pads with turned rotors. Also, wait and see if someone else weighs in on this issue for you.

^ /thread.. lol..

to the OP.. what year is your TL? Make sure your up to date on your brake fluid changes as well. Once you've bedded the brakes properly, make sure one side doesn't pull while you're braking.. if so, redo the process and don't come to a complete stop during the braking successions and don't brake too hard as to engage the ABS pump.

Yeah, I left out a few steps in the bedding in process. As Majofo said, do NOT come to a complete stop when you slow down during the bedding in braking. Accelerate back up to 60 MPH and brake pretty hard each time, just this side of ABS onset. You will experience fade by the 5th or 6th slowdown. Don't worry, that is normal. I would do eight of these with the "standard" brakes.. those which are not the Brembos as on the manual TL (unless yours is a TL-S).

If you're at all uncomfortable doing all of this, you might want to hold off and see how they do under normal use. Interestingly enough, when you buy a new car, the owner's manuals all recommend careful use of the brakes for the first 2-300 miles. And when replacing them, many suggest bedding in to be best. Go figure. This makes me believe that a new set of OEM pads and rotors (or turned rotors with OEM pads) might be best served to follow what the owner's manual says.

What say anyone to this?

Well out of the three threads you started, only one of them has any good advice. Of course it's this one, and that's why it hasn't been locked. Bedding pads is essential to good braking performance. No need to replace pads at all 4 corners or any mumbo-jumbo like that. Old pads grip just as well as new pads unless something has gone wrong...

I hate cars

In addition to what the other guys are saying, next time replace the rotors instead of having them cut. I'm sure this isn't your issue but I hate the thought of taking metal away from an already warp prone rotor.
