I need help on about brake system! My car only had 7k. This recently happen last week on my way to work, Stop at the red light, My foot is on the brake suddenly, I feel my brake paddle is stinking, But it's still braking, But I let go the brake and step it again an is fine. Once in awhile it happen. It's this normal? Or i have air in my brake line? I'm just curious. I don't wanna to bring to dealer look like D##A!

 

Is the brake actually sinking on its own at a constant pressure or are you sub-consciously pressing on the brake harder as you sit at the light?

 

Either way, its a cause for concern. It is safety issue and you need to contact your dealer.

 

Yeah the brake sinking on its own! So this isn't normal right? Thank!

 

Thank! I'll contact the dealer right away. And i will post up the info the dealer give me.

 

I just got back from the dealer. And The dealer mechanic did a pressure test on the brake, And he say is fine, Nothing with it. If it's happen again bring it back to us!

 

Try this.... with the car turned off, pump the brake pedal a few times until you are not able to depress the brake pedal. Now, turn the car on and you should feel the brake pedal sinking. This is normal operation.

 

Are you stepping on the brakes hard? If so thats you anti lock breaks working. If not, you need to get that car in the shop ASP!

 

This is not normal and not good. Take it to another dealer.

 

I am definitely not an expert on this, but my expectation is if there is a serious issue with the brake system (enough to warrant a "take it in immediately" response) then I would expect the system to throw some codes and probably turn on warning lights on the dash. I'm working off the expectation that, this being a critical system, the internal diagnostics will flag anything that's off by even a fairly small margin.

 

I'm bringing to another dealer this Monday. Let see what they say. thank all !!!

 

I had try that already, Turn off the car, Then pump the brake paddle till can't pump anymore. But it do the same things, After i turn on the car, The paddle get softer, Then one in while the paddle sinking down a little, But still braking.

 

Does the A/C compressor cycle on or off, when the brake pedal sinks ?

A slight change in brake pedal height is normal when the A/C compressor cycles on or off, due to the fact that compressor loading will change the amount of vacuum boost to the brake booster.

 

 

I have the same problem on my 2008 TL-S. All the dealers brushed me off like I was making up a story. It is good to hear a reason why its happening. And yes mine does happen when the compressor cycles on and off. Is there any fix to this?

NO. All Honda/Acura vehicles do this.

 

My Tl is still in the shop since Monday, They're still checking the problem. Another question how low is brake paddle when you stepping on it? It's in the middle or is almost to the floor? Another question the brake paddle is soft or hard when you stepping on it?

 

Sorry guy late on the update!!! I got my car back from dealer. Everything was fix! The problem was got air in brake line!
