Braking problems..I need help....

[Ms Grumpy]

Ever since I got my car back on the road I have been uncomfortable with the braking power. We had installed a power boost to help with the vacuum power. But I have noticed that I loose brake pressure/power.

Here is what happens: When I am driving and hit the brakes, I have awesome stopping power. But, when ever I depress the brake pedal and release it, then depress it again my brake pedal goes down lower and I lose braking power. I was told this is because the vacuum canister needs to build up pressure again. I can drive my car, but I have to be very careful, especially in traffic. But I don't want to drive it this way.

So I am considering installing a hydroboost conversion.
So has anyone ever installed or used the conversion ?
Do you know anyone who has it ?
Do they love it, hate it ?
I would love some feedback, please.......
