How to render a view in Express by passing at the same time json object

I have a problem and I'm looking for a solution to figure out it. In ExpressJS 4 I'm using Jade as template engine and AngularJS as client side framework. I get through mongoose module a list of car brands in my mongodb. Everything works. The problem is if I call render along with json.stringify, the browser hungs and I don't get any page. Which could be the best way to pass a json and at the same time render a jade file? The next move would be to create a service to the client side and get the json in order to pass it to the view

exports.index = function(req, res, next){

    Car.find()
        .sort({brand:1})
        .select('brand')
        .exec(function(err, brand){ 
            if(err) return next(err);
                //res.json(brand);
            res.render('index', 
                                 JSON.stringify(brand), 
                                 {pageTitle: 'Home'});
    });
};
