I've had my Reatta for several months now, and although it was incredibly poorly maintained it and doesn't make financial sense to keep fixing it, I've grown attached to it. That said, I've hit an issue that may scrap my car. Both front brake calipers are failing to retract all the way from the rotor and as I understand it, they have been for longer than I've owned the car. Obviously it has negatively impacted the braking of my car and I can't take it on the highway. I've taken it to several shops and the brake hoses and calipers on the front have already been replaced, but the best anyone can tell me is that there is some sort of problem with the brake pump.
Basically, what I need to know: Is the brake pump easy enough to replace for an inexperienced owner? Is it worth buying a $400+ pump when the car itself is only worth around $1500? Thanks to anyone that can help, I would really like to keep this car on the road as so many of them have disappeared already.
