When brakes get hot from long period of stop and go driving,
Brake peddle gets higher until the FRONT brakes are on solid.Had the front calipers
replaced, ABS pressure module / computer replaced and programmed. what other
possibilities, brake line collapse or mechanical half of ABS, doesn't seem like the master
cylinder could be the issue. I have heard of the brake line collapsing and not allowing the
fluid to return to the reservoir. I have been to 4 mechanics with no final solution.
Check out this site:http://www.aboutautomobile.com/Complaint/2007/Chevrolet/Equinox/Hydraulic+Brake I guess it has a bad track record for brake problems. You may be looking at a new master cylinder or traction control module. It seems like the dealers don't have any idea. They just seem to replace random parts.
Thank you, hopefully someone else will come up with a answer, don't want to go to a dealer serv.
Had this same problem on a chevy Impala, to make a long story short, there was too much moisture in the system, when the brakes got warmed up it turned the moisture into steam setting the brakes, once it cooled off the worked fine until they warmed up again. Flushed entire brake system 3 times and the problem never came back. I've heard that replacing the brake fluid with silicone fluid is the way to go but it is still expensive.
Sounds like a strong possibility TNx
