Will this be a costly repair?

Depends. If repair kit is possible, that would cost you around 1k. If not, prepare a few thousands.

Check for fluid leak on flooring under the brake pedal.Maybe the fluid leaks inside (pushod connecting the brake pedal and the brake master cylinder).

If your exhaust fumes smell sweet and your spark plugs are glazed, it indeed is leaking brake fluid past the master cylinder to the vacuum brake booster and into the intake manifold.

so whats the best solution for this since i cant find any leak between the brake master cylinder and booster.

should i just replace the master cylinder with a new one? replace the booster? or buy a brake repair kit?

One way of checking if it leaks through the hydrovac is to pull off the vacuum hose which connects the hydrovac to the intake manifold. If there are presence of oil or fluid, then it is precisely leaking. I would suggest you to replace the entire assembly instead of the repair kit only, as the diaphram in the hydrovac has already been soaked in fluid, which eventually will fail afterwards.

When you say entire assembly, this includes the brake master cylinder?
