I just picked up a 2007 TL-S last week and my pedal feels quite mushy. I am used to my 2001 ITR (stolen), but I can't believe that with the brake setup on this car I should notice a pedal feel difference in mild daily driving.

I guess I would expect the pedal to be rock hard, with almost no travel to it, especially being a brand new car. However, I had a decent amount of travel in the pedal, and it doesn't feel solid. Also, if I activate the ABS, the pedal seems to firm up for the rest of the drive, but then goes back to normal.

Can anyone give me some feedback, especially if you happen to have a '07 TL-S? I know the dealer will probably shrug it off, so I want to know if I am just crazy, or if I should press the issue.

Thanks!

the pedal with deifintely feel different compared to your integra. the integra gas pedal is controlled by a cable, but the tl is computer controlled (drive-by-wire). on the integra, when you step on the pedal it will right away open the throttle, but on the tl when you step on the pedal, it will electronically send a signal to the computer which then interms says, driver is asking for more throttle and send a signal to open the throttle body.
it may feels mushy to you, but i tink you have to drive on it awhile to get use to it

 

Um, I was talking about the brake pedal...

lol, hahahha my bad, hrmmmm, it shouldnt feel muhy it should feel firm, ive driven one before it was very solid. jut bring it to your dealer and have them take a look at it, if the technician does notice something, they will fix it.

 

wow not good i have not seen any to date about a mushy brake pedal yet and we sell a lot of type s i just looked on in and no info as of yet i would have it checked and see what they say.
good luck hope it all works out

 

My guess it either the ABS unit or air in the lines.

If the dealer gives me some B.S., I have a trusted mechnaic that I can take it too; he does more work on NSX's than the dealer's themselves So I can always get a trusted answer from him on what it *should* feel like.

I will post an update later, thanks for the advice guys!

 

I've seen an '06 TL at work with this complaint. Had air in the lines, lines were bled, problem later returned. Ended up being a faulty ABS modulator. Somehow allowing air into the system, without leaking fluid externally. Had an older (99-03)TL in the past with the same scenario, so it's not unheard of but it is fairly rare.

 

Getting air in the ABS modulator can cause all kinds of problems like this. The trick is to fire off the ABS a few times, and then bleed the brakes. If it's still mushy, try it again. The problem is that air can get trapped in the closed passageways of the ABS modulator. This causes a mushy pedal that normal bleeding won't fix.

If repeated attempts don't fix the problem, then you will have to have the ABS system cycled manually with a special computer tool that you can't possibly afford (over $1k).

Here is the thread about an ITR with a similar problem. He finally found someone with the tool to cycle the ABS and it finally let the air out of the lines...

I think the last poster hit the nail on the head. Good to see this kind of insight is still around, and that people take the time to answer a question thoroughly.

Say whatever you like, I've run across this problem twice already where bleeding the system did <U>not</U> provide a lasting repair. Provides a temporary fix and the problem later returns.

Well... The poster asked that he cycle the ABS pump in the process. In your experiences, did you do the same thing?

I work at a dealership and have access to the necessary tools, so yes.

The issue you and 94eg are referring to is a scenario where a satisfactory pedal feel cannot be achieved short of cycling the ABS modulator with the service tool. The scenario I'm referring to is an issue where bleeding the system gives a satisfactory pedal feel, but only for a short period of time (few days-few weeks). The problem returns again and again until the modulator is replaced. Search around the TL forums on Acurazine and you will find others with the same issue. May or may not be the case for Onyx00, but for you to brush off my original response because you are unfamiliar with it is ridiculous.

 

Head into your local dealer (preferably where you bought it at) and ask to drive a different Type-S. Have them drive it if they prefer. Then have them fix it if a true difference exists...

 

Bleed your brakes manually, with some one in the car pumping, instead of with the vacume bleeder. if that does nothing you might need a brake mass. cylender.

 

Take it to the dealer.....the car only has 300 miles. They'll definitely look into it.
