ever since i did my lsi brake conversion ive had a strange problem.sometimes when turn sharply in a parking lot my brake pedal will go to the floor.two pumps and its back to normal.i know im leaking fluid but i don't understand why it only does this once every couple of weeks.i thought it was the master cylinder so i installed a new one.no change.this happens only when i turn very sharply.any ideas?

 

You know you have a leak, and you're driving on public roads? Get it fixed before you run over a baby carriage.

If your master if low on fluid, a sharp turn will slosh the fluid and might cause it to suck air.

 

The caliper or mounting bracket is hitting something, this is pushing the pad/piston into the caliper.
