Hello Sanjeev, (oh dear…*facepalm*- SM)
I am writing you from India. I have a Jetta MkV 1.9 TDI with automatic transmission. It has done about 74,000 km. About a month back, I got the the brake fluid replaced as the service adviser suggested it should be replaced once every 60-70k km. After I got the car back, it felt like the brake efficiency had decreased. I was told its normal and after driving for some time it would be okay. Unfortunately, it never improved.
Yesterday, when I applied the brake, I noticed a burning smell. I took my car to the side of the road and there was smoke coming from the rear brake pads. I stopped to let them cool and then drove back. Since it was late at night I had no help available from VW.
Today, when I took it to VW workshop, they said they are not sure about the problem and have been trying to investigate it for last 8 hours. I am writing this email to you with the hope of getting some suggestions on what should I do.

Gaurav, just so our readers are on the same page, MkV Jettas assembled in India wear 4-wheel disc brakes and the repair procedure is straight-forward enough for your average mechanic. So, even if they serviced the wear items on the brakes (pads and rotors), that isn’t a problem.
Which leads to the parking brake cable. It must be dragging on the brake.
This thread suggests the parking brake lever at the caliper can fall out-of-sync after pad/rotor replacement. It’s possible there isn’t enough slack. This thread suggests tinkering with the lever inside the car works! I reckon that’s your problem and the VW workshop is struggling to make this adjustment!
Some parts of India (hills in the North) are hard on brakes, but in urban areas you probably can’t go fast enough to cook brakes designed for the German Autobahn. I doubt you needed the fluid flush at 70,000-ish km on a MkV Jetta. More miles and many more years on the road is needed for that. But it’s too late for that advice, bhai!
