1999 Honda CRV brake pedal depth

  • 1999 HONDA CRV
  • 4 CYL
  • AWD
  • 110,000 MILES
New front brakes at 105,000 installed by local brake and shock store; still have original rear brakes. New brake fluid also at 105,000. Recently noticed when the vehicle is cold (it's stored in a garage overnight) the brake pedal goes about half-way to the floor when braking. When the vehicle warms up the pedal goes only a couple of inches toward the floor when braking. This just started. When the new front brakes were installed the pedal took hold about 2 inches from the top and stayed that way until recently.
The brake store checked everything out and cannot find anything wrong. They are reluctant to start replacing things when they can't find a problem. Also, they didn't drive it when it was cold.
We reported the cold/hot phenomenon to them. They said as long as the vehicle is braking and stopping as before and there's no difference in handling, we shouldn't worry.
Does this sound okay? Do we possibly have a failing master cylinder or?
Do you
have the same problem?

I can tell you that Honda is well known to blow master cylinders while bleeding if the pedal is pressed all the way to the floor, so it may not be in your head. If you do get a new mqaster t fix it, be careful to bleed pushing the pedal only a few inches while bleeding! I think Honda has a technical bulliten about this.Here is the bulliten from Honda: PRESS BRAKE PEDAL HALFWAY TO AVOID PISTON SEAL DAMAGE TECHNICAL SERVICE BULLETIN Reference Number(s): HSN 1001-03, Date of Issue: October, 2001 Related Ref Number(s): HSN 1001-03 ARTICLE BEGINNING SERVICE INFORMATION On all Honda models, if you're manually bleeding the brakes, make sure whoever's pumping the brake pedal pushes it only halfway to the floor. If the pedal is pushed all the way to the floor, you run the risk of driving the master cylinder secondary piston into any sediment or deposits that may have collected on the piston cylinder walls. If this happens, the piston seals can get permanently damaged and cause a leak. Fig. 1: Secondary Piston You can also avoid this problem entirely by using any of the brake pressure bleeder equipment available through the Honda Tool and Equipment Program.
