Hello,
I have been working on the brake system for my dad's 76 Eldorado. The problem we are having is that the brakes slowly lock up after driving for a while. It has been sitting for about 20 years. The brake master cylinder was bad so we replaced that. We had the problem with the brakes locking up, and research indicated the problem was the hydro boost. We replaced the hydro boost, and then took it out. we drove somewhere between 10 and 20 miles, and then had the same problem again. The possible causes that we can come up with are that maybe the rubber portions of the brake lines have collapsed internally, trapping fluid, the proportioning valve is bad, the master cylinder is bad, The push rod length is wrong, or the replacement hydro boost is bad (it is a used hydro boost).
The brakes seem to apply evenly when they lock up.
We limped it home by loosening the nuts holding the master cylinder to the hydro boost.
Hoping someone knows how to fix this problem. Thanks in advance for any help.
