70 Roadrunner front disc brakes

Ok this may be a dumb ? and please remember this is my 1st mopar.My RR has front disc brakes with no booster,is this right?Every GM car i have ever had always had a booster with front disc brakes.Should it have one or not?Did they come either way?

yes they have disc brakes that are non power

I know this is an old post, but....

70 Roadrunners came with 3 different brake options.
1. 4-wheel drum, no power
2. 4-wheel drum, power (w/brake booster)
3. Front disc, rear drum power (w/brake booster)

I've never seen manual disk on a B body, but that doesn't mean they never made any.

I do remember freaking out the first time I saw a factory manual disk A body, though.

I too, was used to GM and had only ever seen power disk.
