Noise when braking in front

Hissing / grinding noise when braking

Hello

With me, especially when braking gently, there is a regular muffled hissing / grinding noise from the rear brakes. The noise is not audible when braking hard. The noise increases in damp weather or after standing for a long time with the handbrake on. But the noise can also be heard clearly in very dry weather.

Has anyone had similar experiences here and is it due to a defect or poor workmanship of the brake pads?

I can think of 2 options:

a) rusted brake discs, normally after long periods of idle time or in damp weather or after little use of the brakes. Easily remedied by braking more vigorously several times, ideally at higher speeds.

b) Worn brake shoes, the built-in wear indicator makes this noise rather unlikely given the still low mileage below 30tkm. Can be remedied by changing the brake pads.

I'll bet on the harmless a) variant because I know this from different cars, the C-MAX will be no exception.

Dear Congregation,

also with my C-MAX recently squeaking when braking. Strangely enough, only after about 10 minutes of driving. Braking and accelerating at the same time only partially successful, after a few kilometers the same unpleasant noise (if that's the only thing you notice at the Max at the red light, then thank you). In addition: The electronics can only be outwitted for a few seconds; if you accelerate and brake at the same time, the accelerator is automatically removed (automatic car). Seems to make sense too, braking has priority.

First inspection this week at 17,500 km. The master said about this problem that there was rust on the rear brake discs, to be removed by braking (see above).

Only today did I bother to take a look at the windows. Everything smooth in front. But not to be grasped at the back. Both discs are worn irregularly on the surface, mountain and valley with a difference of approx. 1 mm. No rust.

So on Monday I will harass the FFH.

Best regards

Hi,

After several discussions at FFH and trials (accelerating and braking at the same time actually does not work, the fuel is turned off when braking to save fuel) the brakes have now been cleaned, let's see how long it lasts.

This is a defect that must be remedied, free of charge for the customer, a clear guarantee or warranty. It must not be the case that the brake disks wear out so unevenly, ideally all brake disks should be worn completely evenly and without scoring, only then can the brake system also be expected to function properly. So not just a lack of comfort (squeaking), but a serious lack of safety, even if it only affects the rear windows.

A "cleaning" will not help, the only thing that helps is a complete replacement of the brake discs and new pads, and as I said, completely free of charge for the customer and without discussion. I cannot understand the repair measure proposed by the "master", something like that is amateurish to the power of three. Change the workshop immediately and inform the Ford Service in Cologne, they will hopefully get this workshop going.

If you wanted to work very carefully (I'm questioning that with regard to this workshop), you would even have to search for errors, because it is not normal for the brake discs to wear out so irregularly, which other C-Max owners will certainly confirm . Simply switching without having found and corrected the cause of the error will only result in the same problems again shortly.

With our C-Max we also have this dragging with light braking and also the squeaking with light braking. We were also told that you can "slow down" ... No other errors apparent, allegedly.

Thanks for the tip.

Since the FFH employees have so far been very competent and committed (had several problems, from cracks in the panorama roof to defective diesel lines, etc.), I will leave the club stuck for the time being and take a look at the old (free) workshop I trust.

By the way, does anyone have any experience with the Ford Service in Cologne? Or do they just refer to the FFH again?

Have warranty work carried out by an independent workshop? I don't think that's a good idea, if the car still has a warranty on it, I would always go to a Ford workshop with it, they are obliged to provide you with flawless goods, after all, part of the money was with you had paid for the car, by no means "bad" or of inferior quality.

And strong scoring in brake disks IS a defect, there are no two opinions.

No repairs, as there is still a guarantee. Since the mechanic (now retired) has looked after my previous car (Alfa, most recently BMW) for over 30 years, I want to hear his opinion. Maybe I'm too picky.

Obtaining a second, independent opinion from a professional is never wrong, of course.

But if there are scoring marks on the brake discs, any specialist will tell you that these brake discs need to be changed and that this is not OK. At most, you could try new, different brake pads when the grooves are still very small, in the process of being formed, so it may well be that new pads can "grind" them flat again. But if the grooves are of a certain size, the only thing that helps is to replace the panes.

In any case, this is a defect that indicates materials that do not exactly match each other, i.e. the material of the brake pad does not really match the disc material, because it is primarily the pad that should wear out, not the disc. Ideally, it should be worn very evenly and slowly.

Hello,

I have the same problem with my new C-Max. First driven 17000km, EZ 11/2011 and back marks on the brake discs, which you can clearly feel with your finger. Smooth at the front like a baby's bottom.

So I went to the FFH, who looked at them and said: "You have to change them!". Then I asked him about the guarantee: "Hmm, difficult, I have to ask the master first ... Probability that Ford's number is very low ...". If I want that, the windows and blocks will be exchanged and sent to Ford. If Ford doesn't pay, I'll have to pay € 400-500 for the new brakes. GREAT!

This point of view could not be changed by further discussions. Why do I have to bet € 400-500 to find out whether Ford will pay for it or not?

How did it end for you josi?

Hi,

no grinding noise after cleaning the rear brakes.

Opinion of my old screwdriver: No chance of a guarantee, because the grooves are too shallow (I'm probably a little too picky, he thinks). The rear windows will probably not last longer than 40 - 50,000 km. And the discussion that I first have to submit a submission if I insist on a guarantee claim, I also had at FFH.

Best regards
