No errors in Star?

Welcome, Dave.

Sounds like a gunked up front valve block to me.

Dave/ Heer, what type of o-ring material are you using for replacements?

 

[heer123]

X8r seals no errors is it worth trying to bleed from nipples

As Craig it sounds like you have a problem with the front valve block.

 

[Craiglxviii]

If they’re not aerospace grade Viton coated then please rest assured, you will have problems down the line. Take it from someone with painful experience of 50+ valve block rebuilds over the last 6 years!

As Craig it sounds like you have a problem with the front valve block.

Specifically, shuttle valves in the front valve block... but if one is jammed, the other 3 will follow suit.

Plus, as another thought, a fluid flush and filter change will be needed after all this work...

Thanks mate I’ll check the front valve block & do a rodeo what’s the sign when the accumaltor goes & it was fine before it only happened when I done the rear valve block could it have air lock

 

[LostKiwi]

Accumulator failure depends on which one (there are 4).
The two for each axle will post an error in the dash in a large bump which then goes away.
The pulsation damper makes the system whine if it fails.
