I've bought a new car (Tata Tiago) in India earlier this year, One day I observed some sound from car and checked that rear right brake drum was heated way more than rear left brake drum.
I got it checked with mechanics and it took two 20 KM rides to convince them that the problem was there.
They then cleaned up the shoes, assumed it to be a problem with ABS and replaced it with a new one.
However the brake drum at right is still heating. Though the sound is not there.
According to mechanic it's a normal behaviour but I don't believe so.
Please let me know if it's normal or not and what should be done to get it fixed.
