Weird issue when braking/stopped
Weird issue when braking/stopped
This is an odd issue so Ill try to explain.
I have a 2006 subaru forester ll bean edition SOHC. When I press the brake pedal in and come to a stop when its in Drive, the car makes a noise, not exactly a grinding, almost like a pump noise. It only happens when im at a dead stand still. Not an issue with pads/rotors.
If im in Park and hit the brakes, it doesnt make the noise...only slightly then it stops. It seems to be only when im in Drive and come to a stop, then it makes this odd noise. Is there a pump that could be causing this? Or some sort of electrical issue?
Brake fluid is full.

Re: Weird issue when braking/stopped
Sometimes, if a wheel speed sensor is going bad, the computer will think that wheel has locked up, and engage the ABS. If you are stopped, all wheels are stationary, and so it won't kick in the ABS since it hasn't detected a "lockup."
This is all just conjecture of course. Probably best to have a local qualified mechanic look at it, as stuff like this can be difficult to diagnose without being there in person.

Re: Weird issue when braking/stopped
Your best bet would be to have your vehicle looked at by someone qualified. It's not really possible for us to diagnosis your issue.
Re: Weird issue when braking/stopped
I have to get the car inspected in April so it will go into the shop first week then. I just wanted to pick the communities brains to see if anyone has ever experienced anything like this. Its an issue ive never seen or read about before.

This makes a lot of sense. I never thought of that. Ill have to do some more digging on this.foamypirate wrote: ↑Wed Mar 06, 2019 5:59 pm Sometimes, if a wheel speed sensor is going bad, the computer will think that wheel has locked up, and engage the ABS.

Ill try disabling the ABS system by pulling the fuse...then see if it makes the same noise when im in Drive/stopped with brakes pressed. This will narrow the issue down at least. And yes, ill reconnect the fuse before I take the care anywhere. Thanks!

Re: Weird issue when braking/stopped
Driving a standard car I always notice automatic transmissions difficulty going from drive to stop. Dunno if could be a transmission issue but something to ponder. Not a lot to go off of lol.
Re: Weird issue when braking/stopped
I would look to the brake system first as it happens when you use the brake. Brake booster? Perhaps a vacuum pump?
Don't listen to me though...see a professional

Re: Weird issue when braking/stopped
I had a great Subaru (2004 WRX STi) until I sold it last year. It had a weird noise that occurred when I got in (stopped) and sometimes after coming to a stop.
It was the struts. They were *awful*. I had them replaced once after the car was new, then when they quickly went bad again I just lived with it. For 14 years. It really didn't bother me that much.

ABS or traction control malfunctioning
Re: Weird issue when braking/stopped
Does that car have a "hill holder" function (that's when it keeps the brakes on for a bit when you remove your foot from the pedal so it doesn't roll back on a hill)? I'm not sure how it works or if it runs a pump or actuator when your are stopped in drive. But its another thing of the many things it could be.
Does it only make this noise while decelerating, or only when stopped? If you take your foot off the brake while stopped (and still in drive) does the noise stop? Does it start again when you put the brakes on again? How about if you do that kind of quickly (brakes on/off/on/off) so the car doesn't move. Still make the noise?

Re: Weird issue when braking/stopped
Does that mean your renewal is in April? If so, check to see how long an inspection is valid. In MO it's 60 days.
However, if you say the pads and rotors are good, then inspection might not pick up another problem.
