1990 Honda Accord EX, 175,000 Miles 2.2L? engine. When I run the A/C and it gets hot outside the brakes get very soft, and after a short period of time while applying them will bottom out. When it is cool outside, this is no problem with or with out the A/C on. How can I fix?

That car has the booster system on the brakes I believe and it sounds like a vacuum problem. Does the brake fluid reservoir ever get low?

Brake fluid at normal level.

If the fluid stays at the same level and does not drop I would suspect the booster.

Thanks Bruce, Where is the booster located and is this a possible FIY project?

The booster should be behind the master cylinder. I would look at the vacuum line for any problems. Leaking is my suspicion.
