I don't think there's an issue with the brake liners per se - looks like it's the brake actuation system (hydraulics, booster, ABS or related electronics) that failed.

I disagree with this attitude of manufacturer bashing. When a Tata fails folks scream, we told you so, you should have bought a Mahindra. When a Mahindra fails, you could have bought a Toyota.

There seems to be a problem with Scorpio brakes, I think I have read elsewhere too about it. However, we must remember that there are thousands of examples of Tatas, Mahindras working flawlessly out there. There will be many on this forum itself to vouch for the Scorpio Vlx. There are examples where problems do occur and in some cases remain unresolved either due to dealer apathy or other reasons.

WHat can be said about a manufacturer like Toyota, which shortchanged its customers on its so called "premium" offering, the Fortuner, by providing brake drums at the rear. Those brake drums reduce the braking efficiency and are a hazard.

Sorry for the slight OT post.

@ Anshuman > since the issue has already been raised with the dealers, it would be good to follow up with an email to Mahindra customer care and/or take it up at the highest level. You were lucky to have not hurt yourself and others.

It could well be the ABS sensor. It might be getting a wrong reading and not applying the brakes even when the wheel is in motion. Thats prob the reason why they returned the car with ABS disabled.

@Jay - pls read the post properly. I intended to state that Anshuman had faith with Mahindra & he did not go to Toyota & this is no way a manufacturer bashing. I've always been a lover of Mahindra products & at the present scenario, if I were to change my car my choice would be E8 Xylo. Req you not do not mislead.

A full brake failure? This is simply ridiculous. Its an astonishing piece of good luck that it happened at slow speed else you're looking at a serious accident. Keep us posted on the updates.

So, the safety feature has turned into an unsafe feature.

God Save us..! Complete brake failure in a car under warranty? What would have been the consequences if this had happened at high speeds? Even more worrying is the dealer's inability to detect and fix the issue.

You are right, at least with the presented details. But then, if this was indeed the issue then MASS could have replaced the sensors and be done with it.

Would be interesting to know what the cause was.

if it was the ABS sensor the A.S.S. would have tried using another sensor (if available), reason why i say this is because i do not think the dealer will wait for M&M Service engineer to arrive if it was a sensor failure, this is definitely something else. Any idea if they used the DTC for checking error codes?

I agree completely with Jay. No point bashing any manufacturer. I don't think every Toyota Innova sold has been a 100% trouble free complete gem. It is just that with a Toyota, your odds of getting defective parts are much much less than a Tata or Mahindra.

Anyways getting back to the topic, all I can tell you is that Mahindra customer service is extremely responsive and if you escalate the issue to the Regional Service Manger, they will resolve it.

wow!!
generally if one of the wheels fail the others somehow manage to stop the car.
are you sure that no one has tampered with your vehicle??

Check the brake cables (tubes carrying the brake fluid from the master cylinder to the tyres) for rat bites.

What exactly when the brakes were depressed? Did the brake pedal sink into the floor? Did the brake fuel leak out at the spot?

+ 1 to this.
@Anshuman, please badger the M & M guys at all levels, until the actual cause of the brake failure comes out. Since this is a serious issue, feedback on this would help all of us.

I would like to share a experience with my A.S.S recently and voice to the Scorpio owners. My major challenge for servicing my Scorpio is locating a A.S.S closeby. My second service was due and the closest A.S.S was G3 motors (nerul, Navi Mumbai). I deligently fixed up an appointment with them. On the day of the appointment was recieved by cheerful lady customer representatives greeted with roses!!. They arranged for a supervisor who looked familiar to me(supervised my Alto earlier at Maruti A.S.S). With my confidence on him explicitly explained him about my tyre locking problem during braking. They seem to be be aware of this issue and advised that Mahindra had done some change in the design of the rear brake linings - (which is exactly mentioned in this thread earlier) the replacement of linning would fix the issue. I had other issues like noise in power window and oil leakage. Gave strict instructions to keep away diesel or any solvents from the body due to teflon coating.

Hoping to finally have ridden of the problems in the car, I went to collect the vehicle next day morning after being notified by the supervisor the car was ready. Received by the same smiling lady Customer representative and greeted with flowers again. Everything was all normal but not until During delivery, I was shocked to find the car unwashed with all finger markes in the window and still wonder if thats the way the expected to collect. On further inspection I was horrified to find my car being bumped, the right hand side of the front bumper was almost falling off. The Irony here is that they even did a diesel wash and washed away all the teflon. The entire saga led to an escalation to service center Manager. I was promised that every thing would be rectified by evening and offered a drop till office.

Collected the vehicle in the evening - bumper repainted and back in place, unsatisfactory cleanliness, didnt want to pursue it furhter with no choice collected my car.

The vary next day i discovered that the locking problem still existed and also the noise in the power window. Called up the Service manager and reported the issue.

Well so many question flowing in my head here.
What is really the A.S.S upto?
Does it really help employing Customer representative, flowers without professional skilled technicians and no quality?
I understand that Mahindra has done a lot of research in servicing procedures and simplified the standard operating procidures for the A.S.S to follow. Does it really get followed by A.S.S?
Who should be accountable for this entire misdemeanor?

"Complete" failure on a dual circuit "failsafe" system? I think we are missing something here. The only thing common to both circuits, other than the mechanical things like pedal and pushrod, I think is the booster.

Multichannel system. Sensor and actuator per channel. And I'm sure the controllers are designed to fail in "safe mode". If not, it is extremely poor design, and would lead to huge product liability costs.

Since A.S.S. could not locate fault, am sure it is not something as simple as alternator drive belt/ Vac pump failure.

@Anshuman
So pls. do keep us posted as to the diagnosis.
