I was away on business for two months and my car sat (06 AM M/T TL) in the garage.

My goodness I nearly forgot how much fun it is to drive... I sure missed my car!!!

The only problem is that when I braked the first ten or so times, the car would pulse pretty badly. It's gone down considerably, but is still noticably there. I have now driven 200 miles on it (since yesterday), and have braked PLENTY of times and at all speeds...

Anyone ever have this happen to their car after it's been sitting for a while? Any ideas on what the problem could be?

Thanks in advance for the responses!

 

Sounds like you have warped rotors. Acura OEM rotors are horrible.

for the 6MT!

 

I had that issue with warped rotors. But it would consistently rattle my steering wheel while braking.

Not sure if this is your issue.

 

Hmm........

Then my question is how the heck did the rotors get warped if I wasn't even driving the car?

 

I don't think it's your rotors. I think your tires are flat spotted from sitting so long.

That or could be some spot rust causing some rough feedback. Any squeals or noise when you brake OP? I'd check the rotors and bed the pads in again.

 

That's funny that you said that. Because I noticed that as I drive, I constantly hear a rhythmic scratch (dunno how else to best describe it). It gets louder as I increase speed, and slower as I drive slower.

Guess I should bed the pads in...

How do you do so?

Run up to like 70 and then stop?

The only problem is finding a place to do so...

 

Check to see if there's hard spot rust on the rotors. If there is I would hit the rotors some medium grit sand paper then bed the pads in (several 60-10 stops and 45-5 stops). It should clear up the issue. I've had this happen to me several times with vehicles I've let sit for extended periods.
