Replacement Hydraulic Cylinder Cap
Replacement Hydraulic Cylinder Cap
Replacement hydraulic cylinder cap to fit all Hydrastar models, 3/4" and 7/8" corrosion resistance master cylinders.
The main reason hydraulic cylinder caps fail is UV degradation from sunlight. In other words, UV radiation kills hydraulic caps.
There are two main types of trailer hydraulic caps that suit
- 3/4" Master Cylinders
- 7/8" Master Cylinders
Replacement procedure
- If you find the cap missing, it is wise to drain all of the hydraulic fluid from the reservoir and then refill it.
- Once your reservoir is complete, you must drain the air out of your hydraulic system.
- It pays to put a piece of clear tube over your flushing nipple and flush it into a clear, empty water bottle.
Not only is it essential to clear all contaminants from your high-pressure stainless steel brake lines, but it is also essential to view the brake fluid after it settles in the clear bottle.
What am I looking for?
You are looking for clear, uncontaminated fluid. If your fluid has been contaminated, it has come from your piston cylinders and indicates they urgently need cleaning.
Importantly, before you remove your caliper pistons, buy a set of piston seals because the contamination has come through your old seals.
