Brakes!

Hi Guys,

Looking for some advice. I’ve issues with my brakes that may be down to sticky callipers, but not sure and I’m having issues evidencing anything for Audi to honour under warranty. Bought the car at 13k mile, had juddering issues when braking, audi diagnosed 2 warped discs. I replaced at my costs from an indy. Several weeks later, juddering is back, but not as severe. Tbh, Im not certain it ever disappeared as all 4 wheels were also buckled beyond balancing so was difficult to know what wobble was caused by what!! As I also got vibration issues without braking! Ive just replaced all 4 wheels which now correct the balancing issues.
Anyway, I’m trying to rule out/in stuff like failing ABS pumps/module so wondered if there was anything I could do with VCDS to diagnose myself? Some thoughts I’ve had were to open up ABS module, measuring blocks and record the wheel speeds as I drive, specifically when I’m braking to see if there is anything going on. Does that seem like a reasonable thing to do? Am I able to export logs of this to excel at all to look for significant wheel speed deltas? Just wondering if it’s ABS kicking in because it thinks they are spinning out of kilter? it feels a little like ABS pulsation on my foot, through brake pedal. But i understand this can also be warped disc again.

If anyone else has any other suggestions at all on other diagnostics please let me know as I’m feeling a little helpless here!

Please....

Go do an auto-scan and while waiting, go on a nice BREAK with coffee and cookies, then post the auto-scan here when done & so we can look at your BRAKES! :rolleyes:

yup, I noticed I used break, rather than Brake! haha. I had corrected it ( I thought) before you spotted it.

Anyway, I’m at work right now but heading home in a couple of mins, so will post an auto scan in about an hour. There are no faults regarding this issue from memory, though haven’t scanned it for a few weeks.

Some thoughts I’ve had were to open up ABS module, measuring blocks and record the wheel speeds as I drive, specifically when I’m braking to see if there is anything going on. Does that seem like a reasonable thing to do?
Nothing wrong with doing that, but I'm skeptical that it will reveal much.

Am I able to export logs of this to excel at all to look for significant wheel speed deltas?
Certainly. The output if you log those values will be a .CSV file that should open in Excel by default.

Just wondering if it’s ABS kicking in because it thinks they are spinning out of kilter? it feels a little like ABS pulsation on my foot, through brake pedal. But i understand this can also be warped disc again.
To me, those two feel quite different. I'm not sure exactly how to describe it, other than to say that the frequency of what you feel from bad rotor will vary based on vehicle speed, whereas if the ABS is triggering, it will do so at some pretty constant frequency regardless of vehicle speed.

auto scan added, gents.

are there any functional tests I can perform that may help diagnose a sticky caliper then, UWE?

Manual remediation of crud and scrubbing up the calipers, then lubricating is always a good start when playing with rear brakes.

You may find that removing the motors and moving all mechanical's manually, is far easier and when the job is done, it is less likely you will have a hung up unit or damaged 0x53 controller as a result of amperage pull.

Motors are also replaceable and on the cheap thanks to the wonderful Chinese. :rolleyes:

Don't forget your battery charger!

Hi gdallas,
It is important when replacing brake disks to make sure the hub surface they go onto is absolutely clean, as new disks can warp after a few heat cycles with some rust.muck there. A DTI would be the way to go to test for run out. Does the steering wheel shake when braking hard?
Regards HMC
