Brake pedal goes to the floor – sometimes
The brakes on my ’05 ZXW (with ABS) work just fine until I’m stuck in traffic.
When I’m “crawling” to get into an event, or when there is highway construction (“UGHH!”) my foot rarely leaves the brake pedal. Instead I release pressure just enough to let the car creep until I have to come to a complete stop again. Sometimes when doing this for a while – out of the blue the pedal will go to the floor! I have to completely release the pedal then re-apply pressure and the brakes work fine again.
This is the only circumstance that the brakes fail, like I said, at all other times the brakes are just fine.
What are some things I should look into?
