My elderly mother is taking her car to a mechanic tomorrow. I don't want her to get ripped off (it has happened before) so it would be helpful to understand the problem before she takes it in. She drives a Honda Civic, probably 20 years old (not sure). She says that when the car is cold (not driven in a few hours) the brakes work fine. However if she is driving to various places and thus turning the car on and off the brakes start to work poorly. It gets worse the more times that it is started. I don't know shit about cars. Is it possible that the brakes are getting too much fluid or something due to the car being turned off and on many times? I'm clueless here. Any help is appreciated.
