Dear brothers, my Wagon R VXL is about to clock the 5K Kms mark. I will soon take the car for 5K Kms inspection. what more should I get checked, the engine oil, gear oil, break oil and coolant etc? Also, I have been facing this issue that whenever I start the car and drive for some time and then apply brakes, a sound like that of seeti aka whistle like ssshhh can be heared. Some times the sound disappears on its own and some times it remains there till the car is parked. Need advice on this as well. Jazak Allaah Khair.
