Still leaking power steering fluid

[CverHaar]

I have been leaking power steering fluid from the drain hole between my brake booster and master cylinder. Was told that I should replace the hydroboost which we did it stopped the leaking for a little while and within a few days has started leaking again after pulling the camper. What is the next step I should take to prevent this? Thank you for your help

Sounds like a iffy rebuild gone bad or a sand contaminated p/s system sand can enter in a few places through the cap the vent between the booster and master cylinder and when you R&R the booster and its hoses the sand scratches the main piston and its bore which in turn causes a leak at the seal when the scratches cross the seal after awhile.

The high booster pressures can take a grain of sand and destroy the booster in short order.

I agree it sounds like a bad rebuilt hydroboost. I would buy a new, not rebuilt, one.
