Title: Brakes not working properly!
Post by: Daz Auto on 18 December 2012, 14:37
The GTD brakes are just not working properly - sometimes!

Sometimes recently i have had to use excessive force to get the car to slow/stop for turns and junctions :shocked: Last week I was doing 60mph and nearly shot past a turn. When I got out of the car at the shop I was turning into, there was a burning rubber smell coming from the front brakes.

My wife moved my car out of the garage at the weekend. She even noticed how bad the Mk6 brakes were compared to her Mk5.

Today I would have to say that they are working fine again :undecided:

The car only has only done 36k. So the pads should be ok? Or does the DGS wear them much faster?

Anyone else experienced intermittent brakes?

(I have done a topic search and cannot find anything Mk6 specific. Sorry if this has been covered before.)

Should the title of this thread be "Brakes not spelled correctly!"  :laugh:

Joking aside, how old is the car, has it had a  brake fluid change? VW recommend the first change at 3 years, then every 2 years after that. Fresh fluid does seem to make a hell of a difference.

I don't think DSG should wear the pad and discs out any sooner than a manual, but that's dependent on your driving style. Traditional autos always used to require more use of the brakes as the torque convertor didn't allow for any engine braking, but that's not the case with DSG. I don't brake anymore in a DSG car than I do driving a manual.

 :grin:I was actually going to write " Keyboard not writing correctly "

Sorry, can't really help with the breaks brakes.  Perhaps a sticking caliper ?

The car is only 1 1/2 years old.

Maybe that is why I could not find anything in my search  :embarrassed:

Hmmmm... overheating and brake fade?

A colleague suggested that the brakes could be frozen. :undecided:

Not taking any chances... taking it to the garage.

I have 47K on my manual GTD and I would say the brakes are far from knackered.  I actually think they are quite good brakes.  I would be worried and so driving everywhere with a massive gap slowly and taking it to VW asap, before I ended up in a ditch/tree or worse a coffin.

Please don't think i'm being sarcastic but do either you or your wife rest your left foot on the brake pedal when driving?

Sounds like a sticking caliper to me.
Next time you drive it a bit, after pulling over slowly see if any of the alloys Are warm.
Or jack each of the wheels up one at a time and make sure the wheel rotate freely
Does the car go as well as it did? Has your mpg dropped?

I had very intermittent brakes on mine,
Every time I pressed the brakes the braking point on the pedal would be in a different place, had the fluid changed and bled 3 times and no change,
Fitted a new master cylinder and now they are spot on

The wifes coment made me think originally of what Neil sad or servo pressure issue but the burning smell coment made me think more of a sticking caliper.

Sorry, but "brakes" is spelled correctly  :huh: [I've noticed a lot of people spell it "breaks" though, which a different animal altogether]

Sounds like a sticking calliper piston - does the car pull to one side when you brake?

I did an edit... silly me :embarrassed:

Good point. I did not notice the car pulling. Performance is good and fuel economy excellent.

My wife hardly ever drives my car and I don't rest my foot on the brake.

The brakes were fine again on the way home from work yesterday. Going to the garage this morning. Will let you know if they find anything. Thanks all.

Well, the brakes have been checked by the VW garage and are, "100%." :undecided:

What they think happened, is that the brakes had cooled and been completely covered in water. This is entirely possible. On my way home from work I tend to keep my distance from the car in front and use engine braking only. A habit developed when riding my old V-twin motorbike. It had really good engine braking.

So basically I need to modify my driving style :undecided:

In the rain, should I -

A - tailgate the car infront and be constantly dabing the brakes, even thought I have no opportunity/intention of over taking, thus having every driver behind me thinking I am a complete tosser in a car with flash led brake lights?
B - Perform an emergency stop every once in a while to clean the water off my brakes and waken up the drivers in the cars behind me.
C - Allow even more room approaching turns and junctions and get down the gym to work on my leg muscles.
D - Extend the brake pedal over to where the clutch pedal should be, so I can use both feet to brake.


Seriously though - on my way to the garage I had to drive around a 4 car pile up :shocked: 2 cars looked like write-offs. Though everyone seemed ok.

So in the rain, keep your distance, dab your brakes rather than using engine braking and concentrate.

The woman in the black Fiesta that I have just followed for around 20 miles in the pouring rain must have heeded some of that advice. There was traffic as far as you could see traveling at just over 40mph, but she was making up for the slow pace by being right up the arse of the car in front of her, meaning she was braking every 20yrds. At least me being able to see her brake lights most of the time made up for the fact that she had no funking headlights on.

i thought if your wipers were on the front brakes 'dried themselves' by lightly applying themselves so wet brakes should be an issue in these cars?

Interesting, i thought that was only on cars with ceramic discs? Hmmm  :huh:

Does not explain the smell or wifes coments in the original post imo.


I'm an extremely lite braker and have not suffered this on the 6 or the Leon. (years of driving my other cars, 1950s 60s cars will drum brakes!)
I can see the reasoning and have suffered brake issues due to wet discs in the past in certain conditions but it sounds too frequent and other things you have said make it questionable. :undecided:

It has just happened again. My wife tried it and agreed.

Today the brakes are fine again :undecided:

I did notice this morning that the passenger footwell light is flashing bright intermittently. Gremlins?

It is on our cars too iirc. When the auto wipers detect rain the brakes gently "massage" the discs to clear them, so they shouldn't need dabbing manually, unless you don't have auto lights/ wipers on.

Mine has flashed the footwell lights occasionally they go from the 30% to full brightness and back again.  Only once in a blue moon mine and only flash once not over and over.

Nothing on the dash.

I wonder could it be the winter tyres picking up stones of the drive way? Though usually there is a rubbing noise when that happens. Reversing usually fixes that problem :undecided:

Next time it happens I will have to try and get it to VW asap.

It sounds to me like you need to get on to VW UK and arrange to leave your car with your dealers for a few weeks and let them rack up the miles and experience the problem for themselves. That would seem the only way forward in my opinion  :sad:
