Since I'm not really driving the '87 until the engine is fixed, there was one area that had caught my attention that I figure should be fixed beforehand.
For the longest time, whenever the brakes are applied more than 50%, you can hear hissing from under the dash. The auto parking brake release has been plugged since I got the wagon, so that's not the cause. It only happens with the brakes being applied. Last time I fired it up, any touch of the brakes got it hissing, and the harder you pressed, the louder it got accompanied by an idle speed increase. I'm inclined to believe the booster is shot. The brake pedal usually had okay pressure on initial application of the brakes, then gets rather stiff the more you press on it.
If I'm swapping the booster, would it be possible to use an non-ABS Aero booster, like one for a '92-'94? I know those stick out further, but are smaller diameter than the type on the '87. Also, would a newer type even be compatible with the older style master cylinders? I'm just looking at it as far as availability and price goes (I can get the later type cheaper through work) and access to components below it (like PCM or firewall grommets).
