Default Squeeking sound while accelerating. Need remedy.

Hello guys!I am having a strange problem with my Fiesta 1.6. I am not sure if the problem that i am facing is anywhere concerned to the brakes of the car. Three months back there was shuddering in the steering whenever brakes were applied. To rectiy this problem the brake pads were changed, brake bleeding was done and the disks were replaced under warranty.

After this the car was running perfectly fine.Now for the past 2 weeks or so there is a new problem. Initially the squeeking sound used to come after i apply the brakes and try to accelrate. This sound used to come ony when the car is in 2nd and 3rd gear for around 4 to 5 seconds and then used to go off. Please note the sound doesnt come while braking. It comes after the braking and while trying to accelarate.

For the past couple of days, even if i dont apply brakes and when the vehicle is in 2nd, 3rd or 4th gear the squeeking sound arises while accelarating. The sound remains for around 9 to 10 seconds and then fades off. I have also observed that once the vehicle is past 2k RPM the sound goes off. Tomorrow i have taken an appointment with the Ford service guys. Before that i would like to know what is the reason for this problem to occur and what needs to be done to rectify this. I am sure i will get answers.

Sure it is not from the acccelerator pedal? Could just be a coincidence as far as the post-braking scenario is concerned.

Where is the squeaking coming from? Approximately, at least.

Suman, I don't think its the pedal since it disappears after 2000rpm.

Hand brake not fully disengaged?

Belt issues.

It could be happening at a particular point of depression of the pedal - which is before the 2000 rpm point in 2nd gear (in 3rd & 4th gear the 2000 rpm point would anyway be beyond that)

I have a feeling its the brake caliper assembly which is partially jammed and needs attention, either cleaning and re-greasing or replacement of pin or even replacement of the assembly if the problem persist.

For the squeaking sound there could be 3 reasons.

1. There could be a fluid leak from the suspension or a faulty spring attached to it. So you might feel the sound while breaking and accelerating when there is sudden change of speed which puts sudden load on suspension.

2. The sound might be coming because of faulty drive shaft also, which if the case you might have to replace it.

3. It could be because of break not getting released properly and getting rubbed inside the wheel.

a stupid and a wild guess. did you check all the belts are fine?

most belt start sqeaking at low rpms when they go bad and the sqeak disappears as rpm rises since the friction builds up and the belts don't slip anymore.

Might be a long shot, but see if your serpentine belt (or accessory belt) is tight enough.

The handbrake is not engaged. I feel the sound is coming from front left hand side. Hence might not be the accelarator pedal either.However braking is perfect. No issues with that.

Is it because of wheel alignment or balancing by any chance? Also there is a new sound coming. I feel something is broken and hanging under the bonnet kind of in the front right side. It a tuck tuck noise which keeps coming even if the roads are little bad. Is this something related to to the first problem?

tuck tuck noise can also be due to worn out ball joints.
i replace mine when my lancer was 88K on the odo.
how much has your car run ?

Default Update!

The update is the squeeking problem was because there was metal part in the braking system which was not lubricated and it was rubbing against the wheels. The tuck tuck noise that was coming, it was from the rear shock absorber which is replaced under warranty. The service advisor said the work is done but they need to go for a test drive and make sure the problem has got solved. I will be calling him in the morning to confirm. Hope the problem has got solved. Will keep you guys posted once i get the delivery.

That could just be the problem. But then its a new car, could not have been worn out so soon.

Default Problem resolved!

The squeeking problem was because of dust collections between the brake pads, caliper etc. They cleaned and greased the brake drum, brake pads, calipers etc and the problem got resolved. There was a gudgudgud noise coming up from the rear when the vehicle was at low speeds and when driven over pot holes. The problem was the rear shock absorber. It was replaced under warranty.All the problems fixed and the car is up and running to my satisfction. Good job by Ford service guys.
