Dagger2 custom @Qualifier usage

Suppose I'm building a car and I have several Brake beans with different implementations

class Car {
    @Inject
    Car(@BrakeType(value="abs")Brake frontBrake, @BrakeType(value="nonabs")Brake rearBrake) { }
}

@Qualifier
@Retention(RetentionPolicy.RUNTIME)
public @interface BrakeType {
    String value();
}

interface Brake {}

@BrakeType(value="abs")
class AbsBrakeImpl implements Brake {
    @Inject AbsBrakeImpl() {}
}

@BrakeType(value="nonabs")
class BrakeImpl implements Brake {
    @Inject BrakeImpl() {}
}

why does my CarModule have to define @Provides for the specific Brake types? Shouldn't the custom annotation type @BrakeType be enough to determine which impl to inject? Or would that require using reflection, which dagger2 does not use?

@Module
public class CarModule {
    @Provides @BrakeType("abs")
    public Brake absBrake() {
        return new AbsBrakeImpl();
    }
    @Provides @BrakeType("nonabs")
    public Brake nonabsBrake() {
        return new BrakeImpl();
    }
}
