brake pedal is like a brick

So I just got my 73 240z running after its been sitting for about 15 years but the brake pedal wont push in at all so no brakes! There is fluid in the reservoirs. Would you guys just think that the booster is bad and I need to replace it? It appears to not be the stock one so I think it was replaced before I got the car 20 years ago.


The pedal just wont push in hardly at all.


Hoping someone has had a similar experience and can offer advice..


Thanks

Yup, master cylinder or brake booster. Most likely master cylinder frozen.

make sure the vacuum line going to the booster is intact and the check valve in it is working properly
