Need help on lost brake pressure

[decaturforlife]

I have a 85 t-type, today i was moving the car i notice that the pedal was slow going to the floor. I pump the brake and it had pressure but it still went to the floor. So i drove it around and the brake light came on,i check the fluid and it was full, check under the car an d there wasn't any sign of fluid

Hate to be the bearer of bad news, but you have the classic sign of a bad master cylinder.
Hydroboost or PowerMaster?

Hydroboost

That's easy.
If I understand the hydroboost systems like I think I do, you should be able to change that mastercylinder just like any other....except the PowerMaster. Should be avialable at you local auto parts store.

That good news, so now it time to check out prices.

Hydroboost Vs Vacuum Vs Powermaster

If You Can't Find The Real Master For That Car, We Do Have It, Or You Can Use The 77-82 Corvette Master. It Will Bolt Right On, And Is Easy To Find.
