As stated, my brake pressure is low to non-exixtence when the temperature is in the 80's. When it's cool out I have no pedal pressure at all. I live in FL and in hot weather their great. Is it the booster or something else??

Are you driving the car like this?

The pedal goes to the floor?

Have you tried bleeding the brakes?

OP, you need to state the problem more clearly before I can understand it anyway. All I can tell is that you are not satisfied with something about your brakes when the temperature is below about 80 - I think that's what you are trying to say...

My brakes work fine when the ambient temperature is around 80 deg., I have a full pedal. Yet when the temperature during cool or cold weather is in the 70's or 60's or lower, I have brakes, but the brake pedal goes to the floor or I have to pump the pedal hard or quickly to get anykind of pressure on the pedal. Sorry, I mean't to say 70's not 80's. I hope this is clearer.

take it in to the dealer, wait i bet its not under warranty anymore huh?

yea have the mechanic check your booster ( least likely to be the problem) have them check to see if it is leaking(air)

also check your brake lines

wheel cylinder could also be leaking

check your master cylinder ( its sits in front of your brake booster) and check the fluid in that.

it could be so many things because from what you described i don't think you have an idea either
