Guide for replacing old hydraulic lines

[ted928]

My buddy's car had a minor fluid leak on the driver side. The cylinder and pipe/line was fine but it was leaking at the port. I slide the retaining clip out and removed the pipe/line and seal. The seal looked fine. I did notice that the retaining clip seemed to be 'flattened' so it was retaining, but not providing an axial force. I used a small screwdriver to open up the clip so it provided a stronger wedge. It took more force to reinstall but the leaking has stopped. Time will tell.

The leak is back. I would like to replace the seal. Does anyone know where to get the seal?

I swapped the seal with one from the other side and there is still a leak on the driver side (left side) so it looks like the seal is not the problem. I don't see leaking from the rod seal so I think the hydraulic line must be leaking at the swaging. Looks like I will be replacing all the lines.

I just repaired a leaking hydraulic hose at the bow in roof shell 2 using these hydraulic hose couplers: https://cabriolethydraulics.com/hydraul ... -couplers/
It took about about an hour - I cut out the bad section, installed the coupler, and put everything back together. I then refilled the hydraulic fluid in the reservoir near the pump in the trunk - it's self bleeding. All works like new now.
Regardless of whether you attempt a repair, or replace all the hoses, make sure you put the zip ties back *exactly* where they were - I got this wrong while repairing the wiring and the friction from the zip tie is what caused the hydraulic line to burst.

I would like to know which size do you use? 1.8 or 2.0

Wow! You really

• shortened the hydraulic hose?

• put the coupler ino the mid of the upper bow?

As this critical upper bow lacks on a too small diameter, this would enforce the risk of the next crack on these 2 hoses. And, it consumes additional space in this too narrow area, where the 2nd hose will suffer as well.

I'm always trying to extend the diameters of the upper bows when dismantling the roof to increase the lifetime of the hoses. Shortening is an interesting direction...

The original hoses have a diameter of 2.0 mm.

Thanks a lot.
