Hi Paul63, technically curious, as a driver worried now. I too have taken this up with Hyundai. This is serious. I am driving down from Cochin to Coimbatore today. Hope the problem doesn't recur. Keeping my fingers crossed.

In the meantime can you share with me the e mail ID of Hyundai to which you have taken up this issue? I have for starters taken it up with the dealer and the Hyundai customer care. Thanks.

Guess you mean me.

The vehicle was a friends Honda City, of unknown provenance.
A brake pipe sprung a leak, and that resulted in the reservoir totally emptying out, with no braking in either circuit. The reservoir design was to blame, which I put down to someone fitting a non OE part.
Similar to what happened to Ringoism. His is a more detailed explanation.

Somebody else also had a complete brake failure on a modern vehicle on this forum. But did not get back with details.
OK found it

On 2nd Dec, i experienced the panic situation described by navy68, ie. brakes shuddering when applied with no braking function, fortunately was just driving out of my building parking so speed was 10-15 kmph only, managed to steer and then brake to a stop. that panic situation resulted in a severe leg cramp for me.
My suspicion is a faulty control module AND/OR the ABS unit. Any hydraulic leak is a one way ticket. Once that happens and an air bubble forms in the circuit full functionality cannot and will not return to your braking system until the system is bled.

Braking problem fixed, the ASC changed the hub & bearing assy, which hosts the ABS sensor as well. Creta braking well now after strenuous braking tests on Tar and Concrete road stretches, will observe in future drives for recurrence if any. HMIL corporate is also monitoring the issue post my escalation to them

Thanks for updating and I am happy to read the critical brake problem has been resolved. But I must admit at being a bit foxed at the symptoms exhibited by the system vs the solution the ASC has provided.

I took the Creta to the ASC (Shreenath Hyundai Jogeshwari, Mumbai) on 3rd Dec and after a check advisor identified some ABS sensor problem, also reassured that braking function will not be affected.
The service advisor is correct. The ABS sensor in the hub monitors wheel speed and lockup. This data, a series of pulses as the wheel rotates or the absence of these pulses in case of a lock up or if the vehicle halted, is fed into the ABS controller. A failure of this sensor does not cause basic braking function to fail. Please keep a close eye for any unusual symptoms with the brakes till they are proved to work faultlessly over the next week or two.

Cheers!

Great.
I too had an incident-free 450 km drive yesterday. But the question still remains unanswered. Why did the brakes fail if at all it was just an ABS issue and no brake fluid leaks. Hope they come out with an explanation rather than wait for a mishap for further investigation.

Absolutely. The brakes should not fail with a wheel sensor failure. Doesnt make tech sense.
By the way, would anyone of you have the hydraulic schematic and the ABS system layout of the creta?
