Q: My car needs to have its brake pads changed and has a crank sensor problem

Hi there. Before we assume the root cause of the problem, there needs to be a proper diagnosis performed. There is nothing more costly than replacing parts that are not needed or a misdiagnosis resulting in unnecessary parts being replaced. There are numerous things that could cause the stalling of the vehicle from a loose wire harness connector to the internal mechanical components of the engine. For the brake concern, you need to consider the type of symptoms the car is showing. Simply replacing the brake pads does not correct all the possible issues a vehicle could have - there could be lines, rotors, master cylinder, ABS, caliper, or suspension concerns that are affecting the braking performance. A proper diagnosis of both of your concerns via a qualified technician is your best bet. YourMechanic has several available technicians that can assist you with a car stalling inspection and a brake safety inspection to help pinpoint the faults and assist with needed repairs.
