Replaced the front disk pads on my son's 1989 ford ranger 2wd. Now the disk pads are dragging and overheating? Removed and overhauled the mastercylinder, it was cruddy. Replaced both front disk calipers. Repacked front wheel bearings using hi temp grease and replaced the seals. Now I have a cracked rotor that needs replacing. The disk pad was sheared off because of a cracked rotor and had metal to metal grind and loss of braking power. This is all caused by the dragging disks. This has the rubber filled caliper pins that are drove out and in until the tabs retain it? Could these pins cause the drag? They were lubed with hi temp disk brake grease and cleaned before installing. The front wheels get steaming hot with just a few miles driving and normal braking at stops. This is happening to both front wheels? I also drained and re placed the disk brake fluid in the mastercylinder down to the caliper with dot3 fluid. Need suggestions, don't want to replace brake parts every 100 miles!!

I have a 1993 Pontiac Sunbird (4 cyl.). After I start the car with the engine totally cold, the temperature gauge will climb into the red zone before it suddenly drops back down to normal temperature. After the initial climb to the red and drop in temp, the gauge will settle into a cycle of climbing and dropping, all in the lower 25 percent of the guage. I replaced the thermostat and radiator cap. (The thermostat is under the radiator cap.) There is a slow leak of fluid where the filler tube meets what looks like the water pump. However the fluid level is okay. Any suggestions? It seems like it runs fine after it reaches the point where it is about to over heat. Chris
