Default diy brake booster leak '00 es

I have a Platinum Series ES300 - it has traction control.
My pedal is harder than Chinese arithmetic! When I apply brakes I hear a hissing noise down near the pedal. Also, the engine slightly revs up when brakes are applied.

Is there a diy seal repair?

TIA

If you have an air compressor, just pressurize the rubber hose off the intake manifold.

I'm confused. Will doing this somehow reset a seal in the booster or should I try this for diagnosis?

maybe you could get someone near you to help you write whatever it is that you are trying to suggest. You seem to be struggling with coherency.

Pressurize the air line (vacuum assisted brake line) to see where air is leaking. Use low pressure.
