In the last few days when I brake while turning slowly like at a corner or in a parking lot my brake pedal will slightly lose pressure for a split second, its barely noticeable and then it kinda needs a little more foot pressure to stop. After I let off they feel normal again. I have no leaks and the correct amount of fluid is in the resevoir. Could there be a vaccum leak somewhere and where should I check? What else could it be?

 

not a vac problem. might be the master cylinder.

 

When you say more foot pressure, do you mean that the pedal gets hard or goes further to the floor? Other things to check that come to mind are loose wheel bearing, sticking caliper or caliper slide pin, or a damaged or kinked brake line.

 

You kinda have to push a little harder on the pedal because it goes in a little more. I did change one wheel bearing because it was bad and the other side is going bad now.
