Default Rear drive tire locks when braking

Just picked up an 85' Blazer. Brakes are absolute shit. Added DOT5 Silicone to reservoir, brakes don't seem to be pressuring up. Anyone know how to test or diagnose a hydrobooster system?

In2Trux will become famous soon enough

If you had to top up the system with fluid you have to ask yourself why the fluid is low... I would inspect the complete system thoroughly for any leaks.
This could be the reason it won't pressure up. A soft brake peddle could be because there is air in the lines or the master wasn't properly bled.
