Re: Mazda Singapore quality
Another problem : when starting in the morning, upon releasing hand brake and reversing, a loud "bump" sound is heard!
I can quote this problem you have. It is normal for the noise to happen on all auto transmission with drum brakes on the rear(Singapore Sedan model). This is cause by pulling too hard on the handbrake and leaving it on for a long period off time. So when you put into reverse & release your handbrake(especially in the morning), the rear drum brake pads have not actually completely disengage from the drums, so as you back out you will hear the "bump" sound as now the springs inside pulls the 2 pads together and completely free up.
You might say, it never happens when you are moving forward. Well, its because of the rotational wear of the break pads. It tends to be abit more sticky on the reverse.
Try this, on park, always shift to PARK position and pull your hand brake up 3 to 4 clicks anyway your car shouldn't be moving already on park without handbrake.
Hope this help
