Certainly worth a try! I’ve seen some very leaky GSA units continue to function well. And brake fluid is cheap, if a little messy under the car. Maybe a thick rubber (EPDM) gasket to replace the aluminum spacer? Or maybe pack an absorbent women’s product into the GSA to absorb leaky fluid, and change it periodically.I need to buy both a GSA and HPU reseal kit along with a GSA fixing tool if you would kindly email me @ [email protected]
Also, how effective do you think a custom position sensor gasket with a canopy to direct fluid from a leaky GSA would be in terms of preventative maintenance?
