Hi there,

I would re check the booster. Turn off engine and pump brakes to evacuate all vacuum. Hold pressure on pedal and start up engine, If booster is working, Pedal will suck down a little. check that booster check valve is working and the booster is getting full vacuum. Check if applicable pedal free play adjustment try this first
