Here is my issue:
There is a leak where my brake master cylinder is attached to the brake booster. My brake still works and all, but it looses a lot of fluid. I was wondering if its just a seal between the master cylinder and brake booster. There were a few times my brake pedal went down kind of low, but most of the times it brakes just fine.

I went a bought a new master cylinder anyways, and I notice there is a rubber seal that sits between the booster and cylinder. Im just wondering if anyone knows if I should change the master cylinder, or I only need to change the seals. Thanks

Is this just the seal problem? Do I need to replace my brake master cylinder as well?

I'm not sure if a rebuild kit is available or not...

But either the seal or the master has to be replaced.

There is a seal inbetween the booster and master cylinder. Try replacing that first. If it still leaks, you need a new master cylinder.
