Installed new front brake flex hoses on my 2002 T&C minivan. I bought American "name brand" brake hoses online at a reasonable but not bargain price. Surprised to discover that they were made in China, but seemed of relatively high quality. After installation I flushed the system with new DOT 4 fluid and got a nice hard pedal. Put around 50 slow miles on the van and the brakes worked great. However, something happened yesterday while driving in heavy traffic for around 20 minutes in 90-degree heat. The front brakes gradually began to stick to the point where it took a lot of throttle to accelerate. I pulled off into a parking lot and saw blue smoke coming out of both front wheel wells. Both front wheels were extemely hot, so it was plain that both front calipers were sticking. I waited two hours for the brakes to cool after which they worked fine. Drove home (about 3 miles) without incident being careful to limit brake application as much as possible. Since both front calipers were sticking, and I've never had this problem before, I can only assume that the new hoses are at fault. How can a new brake hose cause this problem, if it is the problem? The only thing I can imagine is that the hoses were defective and somehow collapsed when the pressure of the hot fluid was released, thereby preventing the fluid from flowing back out of the caliper. Comments welcome.
