Sorry I don't know much about cars
Our car is a manual if that is relevant. And yes we do have a parking brake.
The brakes seem to be working OK now. Although off and on they
make a noise when applied, some times it's like a knocking noise and some times
it's, well I don't know how to describe it, like something is being rubbed against something else.
It's seems to have to do with the weather though and it's not constant.
This noise I am talking about doesn't seemed to correlate with applying the breaks though. Even when the breaks aren't applied I can hear it.
