Those ABS brakes are acting up on me, whenever i start the car and i go at like 5mph and i try to brake, the car refuses to brake, i mean it will break but you will hear a cracking sound, and then the ABS light comes on and i can brake normally, whats wrong? do i need to clean the sensors?

 

Yes

 

Im taking the car to the dealership to have some parts installed, ill tell them to clean them for me, they are gonna lend me an XC90 V8 ;D!!!
