Brakes are behaving a little strange since early summer 2011.
i30_Brake_29072011067_sample2.mp4 (http://www.youtube.com/watch?v=BT8scLEgmsc#)
And before Ffoxy shows up in a hurry, suggesting the usual silicon spray :lol: I have to say that last week I was going downwards a scarp ramp with 1st gear thrown in and while touching gently the brake, I heard the same creaking noise as above but this time it lasted as long as I kept my foot steady on the pedal (3-4 sec).
Today I left my car at the dealer who doesn't have a clue. Unfortunately it will be fixed (that is, I hope) next... year.
I'm counting on a replacement car for tomorrow.
Brake master cylinder? something else?

That is a strange one... :undecided: Nice shoes by the way :goodjob: (I have a shoe fettish.. :-[)

So, you think it's not a shoe issue :neutral:

Hopefully you getting it fixed easily will be a "shoe in" ... :P

Left hand drive (they drive on the right side of the road in Greece) Babis has gone to bed it is 5.24 am over there :Shocked:

Thanks for that. I was expecting a reply at his convenience. Anyhow, on our RHD cars there is a shaft to transmit the pedal pressure to the LHS master cylinder. My next question was, where does the creaking appear to come from. On our cars it would be easy to identify the right side or the left as the source of the noise, but for a LHD car, pinpointing the noise is going to be more difficult. Listening to the video, it sounds like a coil return spring creak at the 2 points of contact, eg the pedal and presumably the car chassis. :neutral:
-
You are good with this sort of thing Phil... :goodjob:
-
Thanks Dazz,
BTW you helicopter vid will be even more interesting with your latest family addition as well. :lol:
-
I have a few that we did while we were at a motel over the last few days but I will do some more before I make a video...
The Kitten is pretty timid so I better not do that ... :whistler:

I used to swoop on my cat all the time with my helicopter, he didn't seem all that fazed and never attacked it which made him no fun at all..... :lol:

Well, if it is, it's not the sole problem. :rofl: :rofl: :rofl:

I never cease to be amazed how quickly you guys down under can turn a thread about creaking brakes into yet another Helicopter one.
You must hover about waiting for an opportunity to rotate the subject.................. :rofl:

I should reconsider whether is an ishoe or two

that popping noise sounds like the diaphragm in the brake booster. :idea: the brake pedal on babis's car is hooked straight to the booster because its left hand drive,on a right hand drive i30 the brake pedal is hooked to the booster via a rod that runs over to the left hand side of the car,and thats where the booster and master cylinder are.
-
Apart from your assessment of the noise, I said the rest in #6. :whistler:
-
They've just called. My car is ready to go as they didn't hear anything so problem does not exist :confused:
Ok, I know about their policy but I would expected at least that they should test it properly for a couple of days.

Last time the car was in, they had eliminated the case of being a friction issue so I will point them to this "shaft". Thanks for your suggestions.
I have to go over there now. Update will come later on.
-
Don't bother, you don't have this shaft. Why not show them the video & see if they think it doesn't exist after they see it. :undecided:
-
Assuming the brake fluid level is correct, & also assuming the brakes have no other defect in operation, if the noise is constant even when the braking foot is not moving, I'd suspect a brake servo issue.
Silicone spray lubricant is not the solution here :P :P :P

Awe come on Ffoxy, your never gonna make a million (or another million) with that sort of remark. Silicon spray must have some part to play :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl: :rofl:

Left hand drive (they drive on the right side of the road in Greece) Babis has gone to bed it is 5.24 am over there :Shocked:
Ok here is my take on this.
I wonder whether there is a rod connected to the pedal which goes from the left side to the right side of the car then connects to the brake unit in the engine area on the right side.
This rod is catching on something which is causing the noise.
I say this as on some cars, depending on the placement of the brake unit which isn't directly behind the pedal, a connecting rod is needed to allow the pedal on the left to connect to the unit on the right.
Just an idea to check out.
-
Why not show them the video & see if they think it doesn't exist after they see it. :undecided:
I didn't have to as we were finally able to confirm the noise. No suggestion made from them but they assured me that it's nothing serious (???) so I picked up the car (after I put them to write down "brakes checked, no problem found" on the service receipt :wink: They told me to bring the car in again tomorrow.

Douze point /2. There is a rod.
Assuming the brake fluid level is correct, & also assuming the brakes have no other defect in operation, if the noise is constant even when the braking foot is not moving, I'd suspect a brake servo issue.
Another douze point /2 :D
A dealer's mechanic suggested unofficially that the noise is caused by the rod or the servo (I also believe the second)
Silicone spray lubricant is not the solution here :P :P :P
They told me that they did a lubricant spraying on the pedal :rofl:
-
Brake pedal has developed one more, related to the 1st but even worst sound :mad:
i30_Brake_12012012099_sample1_Jan-2012 (http://www.youtube.com/watch?v=FhbJ56FEVS8#)
Since my dealer had no clue (besides he wouldn't admit this noise is a problem at all), I decided to visit another dealer just before Easter.
They replaced the stop-light button behind the pedal but noise reappeared 10min later (besides it happens after a while when driving in town, esp. in hot weather)
It drives me sooo crazy that I don't want to use the brake anymore... +
-
How annoying Babis .. It sounds like one of your side mirrors has broken off and is dangling by a wire :eek: (have you checked this) :lol:
-
2 things to check.
Can you have someone listen inside the engine bay at the brake booster, to see if the creak is there.
also check / lubricate the pivot point of the brake pedal and the return spring particularly where it contacts the brake pedal and the body of the car. :neutral:
-
Sounded like a spring to me
-

I don't think it is that .. Babis hasn't had a spring in his step for a while :whistler:
-
Done the lubrication thing a 1000 times.
They also can't be sure about the source of the sound (I can't either). Engine noise doesn't help.
The brake-booster was once mentioned, but I think they are just waiting for the waranty to expire... :evil:
One thing that seems odd enough (and I didn't mention so you don't think that I'm crazy) is that, every time I stop near a motorbike (those ones with 1-cylinder and 600+cc) brake pedal is trembling faintly to the rythm of the... bass :wacko: Thankfully, there aren't many Harleys on our roads.

I don't know much about motorbikes :-[

Don't mind us, Babis, we are just teasing... :D

Just remembered this brake test I've done 9 months ago, just after the strange noise appeared (the green words by me)
(http://i949.photobucket.com/albums/ad338/babis_xo/i30/brakes_test_IMG_1174.jpg)
Seems that brake perfomance (60%) just exceeds the min. requirements (55%).
Front axis brake power is 1680 N, a narrow performance IMO comparing to the rear axis brake power (which is BTW uneven with 2080 N Left and 2120 N Right).
Handbrake is already fixed (at least so I think).
Numbers confirmed the strange feeling I had when braking. I can't say if it is due to time wear, but I'm pretty sure that it came up along with the creaking noise and the vibrating (on idle) pedal when a single-cylinder XT-600 passes by :confused:
Dealer does not consider the brake perfomance and the creaking brake as related and since numbers are typically OK, I can't claim anything.
- Has anybody done a brake test?
- What is the normal (not minimum) figures for a car with only 18.000 kms on clock? disks /pads were in perfect condition by the test time (I always slow down using the gearbox)
- Is it ok that the rear axis is braking with 20% more power than the front one? As I've said before I don't drive a motorbike but I think that braking /locking the rear wheel is strictly forbidden.
- Is the uneven braking on one axis normal for a car with ESP? or it is uneven just because of that?
- Should I expect a further deterioration as kms are added on the clock? Although today, after 8.000 kms, nothing has changed.
- What was the real name of Marilyn Monroe?
The first who answers, wins an all-inclusive trip for two :p
-
O/K I'm the first to answer (so where are we going?)
BTW.. I have no idea of the answer to your question :whistler:
-
I'm a bit :confused:
-
Dunno about the brakes. I guess if they stop ok then that's all that matters.
Marylin Monroe's name was Norma Jeane Mortensen Baker BTW
No prize, Dazz beat me to it.
if it's to Panorama on a donkey, he's welcome to it :lol: :mrgreen:

C'mon, nobody has?
a "MOT" test maybe?
an obligatory one?
:rolleyes:
-
I can't remember anyone mentioning it Babis :disapp: (maybe someone will spot this that can help) :confused:

I performed a brake test yesterday.....and they worked. :D

Ok, but I would be obliged if you two, had a Newton force-meter attached to your right foot as well :lol:
In Greece (and everywhere else as far as I know), every two years we have to take a safety test (MOT). The brakes are tested too and the results (N) are printed on a paper :p
Anyway, that's what I'm looking for :foottap:

No such tests required in Tassie (I think it is 3 years in some "North Island States" :whistler:

No such rules in the wild, wild west. :)

i know that if you get a road worthy certificate done on an older car i Victoria a braking test is part of the road worthy test. :winker: but this is only done on a vehicle being registered from scratch,not re registered. :wacko:

Just further on that comment from 2i30s....if you buy a secondhand car (in Victoria), it also requires a roadworthy certificate before you can register it in your name... :)
In Tasmania you don't...is that still correct, Daz? :undecided:
-
And also, if you register a car in Tasmania you have to provide a certificate to prove that you've taken at least one horse & carriage off the road, otherwise they hit you with FGT
(Flatulence Gas Tax) to compensate for your horse's emissions.
They're doing well down there and catching up quite quickly now. :lol:

So each territory has its own rules? Very confusing :confused:

Hey Babis, sorry about your issue, i'm deaf so would not worry me at all :rofl:. but if it was a safty issue i would feel it. my advice is louder sound system or better sound proofing in the floor.
cheers
ps did you put your best shoes on for the video? :rofl:
