The Brake Pedal May Feel Hard After Vehicle Has Set For Extended Time on Honda Accord

Problem Description and Possible Solution

If the brake pedal feels hard the first time it is pressed in the morning, it could be due to a problem with the vacuum supply hose for the brake booster. A revised brake booster hose is available to address this concern.

My brakes are also not working in the cold weather. Same thing where you push the brake pedal and it will not go down. Has happened 3 days in a row now (weather very cold where I am driving currently) - If you let it warm up it resolves, but this is very dangerous! Hope it is easy to fix.
Brakes get hard and don't stop the car. Replaced master cylinder and brake booster. Suspect issue in check valve.
very cold mornings no brake (hard) backing out of driveway and at the stop sign 70 yards up the road, can't stop
The brake pedal becomes very hard during winter time when it is very cold. I have having this problem years ago. The brake pedal goes down when the engine warms up for about 5 minutes or so. I do not have any solution yet. I have taken it to the dealreships but they could not find anything because the car was already warm by the I got there. I bought this car in 2007 and have been having this problem.
When the temperature is in the single digits and the car has been sitting for hours the brake pedal is rock hard and takes several minutes or a couple stops before it will release.
Brake petal is real hard and won't go down or stop the car when it has been sitting outside in real cold weather. Only happens if temp is about 10 degrees or colder. Going to cause a wreck some day as this has happened numerous times. Honda recently told me it might be a valve in the brake booster line. Going to gave that checked out before winter comes.
Only an issue when outdoor temps are below 30 , first time I push brake to put car in reverse its ok then brake pedal reak hard and brakes barely work, almost caused accident. If you let it run for a minute or two you can hear a very quiet "click" then brakes work fine. One time at -3 degrees the brakes did this while driving, very dangerous
We recently picked up a used 2005 Honda Accord Hybrid where the brake pedal is hard when the car has been resting in cold weather. First press is normal, second is tight and goes about half way, third press is hard and brake will not depress. After Releasing the brake then waiting 10-20 seconds, the brake operates normally. The main discussion says there is an updated version of the brake booster vacuum hose available. I've found part number 46402-SDR-A04, which is the vacuum hose assembly. I do not see any indication that this part is the updated version of the assembly/hose. The assembly runs about $50 so I'm willing to buy it and see if it does the trick, but does anyone have more info on this topic? Thanks!
brake pedal hard in the morning after sitting all night.
Car wont stop. after puming brakes its ok until the next morning. replacedmater cylinder still same problems
If car sits a couple of days without being started, when you go to start it the brake pedal is stiff, and you can barely push it in far enough to activate start pushing button. Took it to shop and they had all kinds of excuses but did not fix it.
Same problem with my 2010 Honda Accord, left with dealer for a week (forecast to be below -10C that week), and found that it is the vacuum hose need to be replaced. So far there was no more problems for the rest of the Winter.
The brakes don't work and need to be pumped several times before kicking in when temperature is below 25 degrees and the car has been sitting for over 4 hours. The first time this happened, I backed straight out into the street and hit a snow bank . Thank goodness it was a snow bank and not a car. Very scary.
Brakes dont apply as normal on a snow day. I feel spongy brake pedal and car wont stop immediately, It happens only in cold weather and mostlyu during taking turns, I had the brake fluid replaced recently
Very cold weather brake pedal goes down the first time so I can change gear but will no go back down. Need to try to pump it for two or three minutes then it works. Very dangerous. Mechanic could not find problem.
Only on extremely cold (below 10 degrees) mornings after car sits outside overnight. If my car is in the garage - it will never have this problem. Except of course at end of work day for commute home. It usually last for about 3-5 minutes.
In the morning the brake pedal is very hard. After working it a little it works fine. Problem is not yet repaired.
Honda pilot, brakes very stuff when temp very cold 0 to -20 takes multiple attempts to loosen brakes.
Can't depress brake pedal if car sits for more than a few hours. Once the cars starts the brake pedal moves freely. Also, car stops fine but even after car stops, brake pedal continues to creep to the floor
When first cranked in the mornings or when setting for long period of times my car shakes real bad and my brakes are hard toboress down.
When it is cold in the morning brake is rock hard. Takes awhile to warm up and even then s few times to depress normally
