Just replaced my accumulator now when I turn on ignition the pump runs for about 10 seconds after 6 press on pedal comes back on again does this sound about right thanks for advice what I’ve noticed is there’s a clicking sound at the brake pedal not every time though

is that 6 light presses, or firm ones? Typically its 4 presses with a new accumulator

It sounds a bit like that but from the pedal not the engine side

in my case, i got someone else to push the pedal and I could clearly feel it through one of the brake pipes, think it was the one that went down to the reduction valve underneath the coolant expansion tank

The return spring on the brake pedal started to click on mine, a quick spray of 3 in 1 cured it.
4 hard presses of the pedal before the pump runs again is about normal.

What was wrong with the pipe then to make that noise did you ever discover

What did you replace the whole unit or just the reduction valve thingy you mentioned

It is something internal to the modulator that is making the noise for me, the pipe was just a conduit. I'll eventually strip it down to see what has happened. I replaced the whole unit with a used one off eBay, the reduction valve seems to work fine

Did check this morning definitely coming from pedal not modulator and checked with nanocom test all valves operating properly so will find return spring data posted and spray that
