#110 of 112 Break don't work first time in Cold weather
Jan 15, 2011 (5:50 am)
I have a 2006 Honda CR-V Ex and we get a lot of freezing rain wet snow here in the east. When it's cold and there's ice or snow the first time I press on the breaks there is very little reaction from the car, if you forget about this it is quite alarming.
My practice now is when I pull out of my driveway I start driving down the street and do a hard break to warm up the breaks. Once I do this the breaks are fine for the rest of the drive. This can't be normal, several times I've been looking for a "soft" place to crash when I hit the breaks again and it stops.
I've mentioned it to the dealer but of course they can't find anything, problem is if I've driven there I've already warmed up the breaks. It usually only happens in the morning but sometimes in the evening if the car has been sitting out in the cold weather for a while.

Does it feel like the power assist isn't working?

That's what I was thinking...that his power brake booster is somehow not getting enough vacuum (or has bled out the vacuum reservoir) at first start-up. If that's the case, I'd check for vacuum leaks but if it's some internal problem with the booster, that could be tricky to diagnose.
It would be interesting to note if the pedal "feels" different upon first application---very hard and unyielding.
It would also be interesting to see if you could "stab" the brake pedal a few times before starting out in the morning, to see if that corrects the problem.
