Has anyone fixed the brake judder?? getting annoying now

Recommended Posts

As the title states guys,

 

Has the been any fixes at all? I've had new front pads / disks and covered around 10k so far and doesn't give any signs of it easing up.

 

long distances journy's and when i have people sitting in the back it seems to be worse, even to the point where passengers ask if the car should do that. 

 

The car has it's tracking done on a hunter system when i had my wheels refurbished so would like to think it's nothing to do with alignment etc. 

 

Shame as it takes the smoothness away from the car on motorway trips which i do a few times a week now.

Tyres incorrect pressure or damaged or cheap nasty tyres that vibrate?

 

Sticky caliper or pads, strip , clean and lubricate pad contact points on the cradle may help.

 

Worn suspension joint.  Lower arm bushes can give a shimmy under braking.

 

What make of pads and discs did you go for?  Genuine or OEM?

A few things to consider then hmmmm.

 

Pressure is fine on the funflats with good amount of grip left on them. 

 

They are Brembo pads and Zimmerman disks.

My first port of call would be to check the wheel sits flat to the hub.

 

When you go for your wheel refurbs, ask they guy there what he does on the mating surface of the wheel to hub.  I have heard stories about powder coated wheels being coated on this surface when BMW don't even paint them and giving rise to vibration.

 

Mine are powder coated on this surface but its vibration free.

Hopefully i can get it resolved soon as i will start to lose the love for car at this rate. 

 

If i can't i'm not investing any more money into the car, but then again who would buy a car that judders under braking when they test drive it.

Have you had the wheels rebalanced? I had an issue where I would feel a little vibration on the steering wheel. Turned out one of the wheels was unbalanced and acted like an oval because all of the weight was on one area. I went to a specialist as very few places offer precise wheel balancing and they used a computerised balancing machine and spun round the tyre and reset it on the rim. Standard tyre shops just stick on the tyre and put a weight on the opposing side of where it is heavy. It was like driving a different car afterwards, it was that noticeable.

Just found a wheel alignment specialist near me may give them a visit over the weekend. 

 

The judder does not fill me with much confidence when the cars remapped and i brake.

Only the hunter system which i was told the were no concerns on balancing and alignment whilst they had it etc.

Does it vibrate during normal driving and without the brakes being applied? If so then it is wheel or suspension related and not brakes as I would expect brakes to cause juddering only when applied.

 

If the judder is felt only when you press on the brake pedal then it could be warped discs which is easy to detect with a specific gauge to measure the "warpedness". Or it could, as others have said, be a sticking or seized caliper that is causing the pads to be applied unevenly to the disc causing disc warping.

 

An extreme reason could be a failed or failing engine mount or sub-frame bush but that is highly unlikely.

What do you mean by judder? 

 

Do you mean when you come to a stop the brakes make a low frequency creak type noise? If you hold the brake just off from a  dead stop and allow the car to creep forward do you get a groaning and creaking noise?

 

If so I'm trying to track this down too and find if the brakes are hot it does not happen. I think it might be a glaze from not braking hard enough.

 

I did find some easing of the symptoms by taking the brakes apart and cleaning up the brake pads and guides etc but it came back.

All my auto cars have done this. They have had genuine or OEM pads and discs.

 

But yes, I'm not hard on my brakes, got over 70k out of the pads and discs on my last E60.

I was thinking yesterday after i had written the title i should have added more info. 

 

Mine only seems to be doing the 'judder' at higher speeds, i don't notice it when first starting and setting off.

 

Definitely only happens once above 50mpg and more spirited journey's . The rest of the car is so smooth this is starting to bug me ALLOT.

 

I'm also prone to the vibration around 60/70mpg and then it's gone over 80mpg, that seems less these days whilst in Sport mode etc.

I'd suggest this is not brake related as you would only notice that judder when applying the brakes and you refer to a vibration and not a judder.

 

Wheel balance - most likely - or a suspension issue is where I would look especially as you say it goes above a certain speed. ( I long for the day I get to 80mpg! :-) )

 

Also, wheel alignment would not cause a vibration but would cause the car pulling to one side or the other or  uneven tyre wear.

Sounds more like engine or drivetrain issue or suspension component worn if it's a vibration at speed. Could also be worn tyres. Mine was a bit jiggly on poor roads until I replaced the front tyres.

I'd love to swap my wheels/tyres for a new set just see if it changes anything.

 

Ask nicely on here and someone hear you may have a set of winters etc to try on your car.  That would rule out a wheel issue etc.

 

If you can be in Renfrewshire tomorrow morning, you can try out my set of winters...

Could be lower wishbones...

 

Indeed, could be anything, and that's the problem, these sorts of issues are a pain to diagnose.  You need it up on a ramp to poke at every single balljoint and bush to check for wear or excessive movement.
