New Lines NO Brakes
Posted: Mon Jun 18, 2018 10:09 pm
The old lines on my 67 SS elan were getting rusty and I noticed a seep from one of the SS braided lines at the front wheels. The engine was out so I decided to tidy things up.... Brakes were working fine before I replaced the lines. Care was taken to blow the swarf out of the lines prior to installing them as I manufactured the compression flairs. All the unions were cleaned and new fittings used, new ss hoses installed and a vacuum bleeder was used to draw new fluid from the master cylinder. The master cylinder is a dual circuit system with no brake booster.
I pumped a quart of fluid through the system but cannot build pressure at the pedal. The car has been sitting for about a month in dry storage while the lines were open and fluid removed while I replace parts in my spare time. The lines were still on the Master cylinder as I started from the back of the car installing new as I moved to the front. Since I can't build pressure I cant check for major leaks.....
My feeling is the master cylinder is in need of a good prime OR rebuild. When looking in the resivoir fill spout, you can see fluid coming back up when releasing the pedal while it is being pumped.
The whole system was about 30 years old since the lines were replaced. I rebuilt the calipers around 10 years ago and everything was working fine then. Guess stuff gets old...... Greg
