I have a 94 Accord and when I run my air conditioner it seems like my brakes want to go to the floor almost when I use them. The brakes are normal when not using the AC

any thoughts or hints on whats up??

I can't think of a connection between the A/C and your brake problem, unless, when the A/C is on, it adversely affects the vacuum going to the power brake booster. Still, I don't see why the pedal would go almost to the floor. Be sure to check the fluid level in the brake master cylinder reservoir. Also, check the fluid level in the translucent reservoir going to the anti-lock brake system (front left). You won't be able to add fluid to this sealed reservoir. My wife had a 1994 Accord EX and the ABS reservoir went dry. It was a $2,000 repair bill. Honda had problems with the ABS on '94 Accords, where high pressure lines would leak.

Keep us posted, if you identify the exact cause.

Hi. Did you ever get this problem fixed? If so, what needed to be fixed? I ask because I have a 94 honda civic with the same problem.

All of the mechanics who have looked at it are confused as to what is causing the problem because we have new rear and front brakes and had the brake lines checked out and there's no air in them.

Any help would be greatly appreciated.

Well thats a new one for me,lol...it mite just be a coinsadence that this is happening.If your fluid is full and there are no leaks it could be your back brakes need adjusting,in constant city driveing you use the brakes all the time so you wont notice the pedal going to the floor because your allways pumping them in stop and go traffic,on the hwy on a long ride and not useing the brakes the pedal will go to the floor if rear brakes need adjusting,hope this helps

I have a 1987 Honda Accord too and was having problems with the brakes going to the floor, but that car doesn't have AC...I wound up having to replace the brake booster (wow they are expensive!!!!!!) SO I really hope that's not the case with my 94 accord tooo....but yeah it only seems like they go almost to the floor when I am running my ac...strange huh??

Have you tried backing up and repeatedly hitting your brake pedal to adjust your rear brake shoes?

Oooops bad news.......the brake pedal is still going to the floor even when I am not running the AC. My friend keeps saying I have air in my line...could this be what is going on? would that cause my brake pedal to go to the floor?

Absolutely! Check for the leak, first, and then have the brake fluid completely changed.

Check to see if your missing barke fluid in the resavior,if so you must have a leak.Brake fluid doesent evaporate.Mite be a brake line or hose? If not adjust the rear brakes,,backing up and slamming on the brakes some times works but not all the time..its takes 5 miniutes with a thin flat screw drive,unless you have the brake tool.
