Yes your quite right we haven't. I had forgotten about it as we had to wait for some more dosh so that we could get the caliper done.

Is there a name for this pipe, when I google flexible pipe ABS there are quite a lot of results mostly about water pipes. Do you have any idea how much a new pipe might be please?

Cheers.

Its just a brake line, you can buy them from Euro Car Parts, they cost very little.

Flexible brake pipe is its name and there about £20.

Normally with these as they get old and the insides soften you can get a small piece of the rubber lining floating around inside the pipe and when its under braking pressure it acts like a one-way valve and allows fluid to flow down but not back up so i effect it holds the brake on, and then it slowly allows the fluid to drain back again ,its often missed as when the brakes are bled by the garage all seems well as its not under full pressure.

OK thanks for that. I will get that sorted today. Would this brake pipe make the brakes on that side do that noise as I am driving along, as it doesn't only do it when I am braking.

Cheers.

has anyone checked the back ones?

geekgirl

No they haven't cos all the noises are coming from the front passenger side, could a problem with the back brakes do this?

From inside the car, it can sometimes be difficult to be sure where the noise is coming from because of sound reflections when you are moving. Sometimes it is obvious, and may be in your case. I'd check the rear pads yourself, make sure they are not worn down to the metal. Also, jack the car up on the flat wheel by wheel and see how they spin with brakes off.

The bit about the ipod is intriguing, is this electrical interference (crackling) or physical?

I have asked lots of passengers front and rear where they think the noise is coming from and all have said the same.
OH has done the jacking up thing (wheels not substances!!!) and all was well.

The ipod thing is crackling like electrical interference. Weird I know but thought I should describe as best as I can with such limited knowledge.

was the crackling before the ABS replacement, or after.

Did OH check the rear wheels/pads? Do these noises sound like metal to metal contact? Gentle hum, or squeal?

Yes it was crackling before ABS replacement. Not sure about whether he checked the rear brake pads. The noises do not sound like metal to metal it is a huuuuuuuuuummmmmmmm noise if you get the picture. It will do it for about 4/5 seconds and repeats it about 5 times then doesn't do it for about 100 yards or so then starts up again. And does it when I brake.

I was trying to find out if it did the ipod thing after the abs replacement. Relay maybe?

You need to rule out any problems with the rear brakes really, but any competent mechanic should have checked them. You should be able to quickly check them without taking the wheels off.

I will ask OH if he has looked at them and if not get him to do that when he is back. Nice brakepadhenge picture.

Hi

I read through all your posts and the way you are describing that "noise" is suggesting the ABS sensor is not happy for some reason. To support this theory, you mentioned "crackling noise of the ipod" which you used to hear before they replaced the ABS sensor ( Second hand one) on that wheel, but, you didn't mention if you still hear the crackling now! Do you still hear it when the noise happen now?

I have strong doubts that it will be the ABS system is causing the problem. You mentioned that the noise can happen for 4/5 seconds and then nothing till 100 yards later when it happens again. When it happens again after 100 yards, does it happen because you used the brakes, or just out of nothing?

If it happens after 100 yards after using the brakes, then the collapsing flexible brake hoses theory gets stronger, but, if it happens out of nothing, then, the flexible hoses collapsing internally theory gets weeken alot!. The ABS sensor on that wheel or the other wheels should be suspected.

The ABS sensors are monitoring the rotational speed on each wheel by looking at/facing a a small disc with teeth on the back of the brake discs( The ABS rings).
These teeth might have some flakes of rust which can confuse the ABS sensors, resulting in erratic behaviour of the braking system.

Does the ABS light on the dashboard comes on when you switch the ignition on before you start the engine? Does the light go when you start the engine?

I can't remember if they ( the ABS rings) are replaced with the brake discs or not, but, it is worth cleaning these.

If you still have a problem, ask your husband in this lovely weather to check the ABS sensor on each wheel by using a multimeter ( If he doesn't have one, he can buy one either from the RANGE shop for £3.99 or from BOYS if you have one close for £4.99 or your local ALDI if they have some left from previous offers) He must set the multimeter to read ohms. Removing one wheel at a time, unpluging the sensors cable and test its resistance. All the sensors need to give virtually the same reading. If one sensor is giving significant different reading, then it is faulty and need to be replace. Some sensors lose their original resistance to a certain degree that will cause problems with the brakes but not bad enough to cause the light on the dash to come on.

Don't forget to ask your husband to check for any loose wiring, insecure relays or fuses related to the ABS that might be causing the erratic noise of the brakes!

It is fairly common to have problems with the ABS sensors passenger side due to frequent holes and bumps on the road when you drive on the left hand lane. Just a theory!lol

Good luck and keeps us updated!

This not an ABS/electrical issue, the brake is binding and wearing out the pads on one wheel (NSF)....Correct..???????
