I live in China and have a 2002 Siena. The brakes begin to stick (staying on with varying degrees of slightness) once the temperature gets over 25 C. At 30 degrees C. They get sticky enough so that the brakes get very hot (judged by touching the wheel rims) on just a 10 mile drive. Below 15 deg. C. They don't stick at all. I'm afraid I'm frying the brakes, but I'm waiting for the Fiat dealer to get a new brake pump, which they said is the problem. I'm skeptical about that though, because they don't seem very competent and seem over eager to replace anything that has the slightest problem. The brakes don't stick at all if I just use the hand-brake, but once I use the brake pedal, they get progressively worse the longer I drive even if I stop using the pedal and just use the hand-brake. Before I pay for a new brake pump (and they said probably they will change the ABS pump also), I want to find out if it could be anything else like a stuck valve or something I don't know exists. Both front brakes heat up evenly, and the back don't get hot at all. The Fiat dealer put new rotors and pads on the front, but the problem seemed exactly the same before and after that.
have the same problem?
