Hello

this sounds like there's a lot of air trapped in the ABS pump

the dealer method of solving this is to use the diagnostic system to run the ABS pump and bleed the calipers as normal

however I've had success in the past by taking the car for a short drive and hitting the brake pedal very hard to get the ABS to trigger and so run the pump

then bleed that corner again to get the air out

you may need to do this a few times

Hello

OK if the there's no fluid at the master then the master needs to come off and apart for inspection / new seals - or replace it entirely
