Hello, recently aquired 87 Dakota, already replaced both front rubber lines... Brakes fine in cooler weather, but warm days make both front brakes pinch.... 150K, no indication of master cylinder ever replaced..Ideas?

 

calipers must slide on the mount pins. clean off the rust and lube lightly with high temp. grease. My 90 calipers started binding with new pads so I ended up replacing them.

 

Thanks I'll try that! Appriciate the help!
