So I'm cruisin around yesterday and I smell burning brake pad. It starts getting worse so I pull over to check it out and my passenger side caliper is smoking a little and there is a lot of heat comming from the rotor. I get back home, jack up the truck and try to spin the tire, still realy tight. So I pop the caliper off and notice that the one piston is stuck, so I compressed back hooked the brake line back in and compressed it to see what it did and only one of the pistons engagaed. So what the hells the deal with this? Is there any way to free this thing up or do I have to buy a new Caliper? What a pain in the ass.
