When i press the brake pedal the booster starts buzzing then stops after a minute or so. I didnt have how to test the booster i just took the guys word for it

Hello fellow lexus owners

Im having a bad time with my mk2 gs300. 

The brake booster started playing up, making squeaky noises then eventually stopped working. 

So i found a replacement online (secondhand) and fitted it. 

Now heres where the problem starts:

I can hear the brake booster working, making buzzing noise but the brakes are still bad, meaning the pedal is still going down and i have to double press the pedal to get the brakes working.

VSC, ABS, VSC OFF is still on

i did unplug the Battery when i changed the booster

i also bled the brakes

i connected it to obd, gave me a fault code

C1322 ABS MALFUNCTION 

im literally out of ideas now, please can anyone help me
