2002 Jeep Grand Cherokee Laredo 4.0L The front passenger side brakes are sticking closed causing heat buildup, poor gas mileage, and generally poor acceleration. I have bled that brake and have manually opened calipers. After sitting for a few minutes they gradually release but if brakes are applied they stick again.
First you must look closely at the caliper and determine if it is sticking on the slide or is the piston sticking. If it is the piston you would have to rebuild the caliper or replace the caliper. If it is the slides, you need to sand and clean all the slide contacts and lube the slide with lithium grease or never seize grease. Then you can reinstall the caliper and you will be fine. Also when checking if the piston is sticking try loosening the line and see if it retracts, if it does you may have a bad flex hose going to the caliper holding pressure on the caliper.
