brake problem

When i make left turns my brake pressure goes away and i have to pump the brakes to get it back. when i make right turns my engine boggs out and it takes about 3 seconds to get going again. any ideas?

As for the right turns, if you have dual carbs the fuel supply can get a little out of wack on a turn or your fuel lines may be run to where on a right turn the fuel moves and the engine sucks a little air. For the left turns you may have a hole in you left front brake hose. When you're turning the stress may move the hose to dump enough pressure to make so you have to pump the pedal. Check your brake fluid level, if it is low you have a leak. Also sometimes if you get water from setting in the brake system it can help lead to this problem.
