Re: Hot Brakes
Ok...so more experimentation this morning. Start the truck...pump the brakes
several times. If I stick a large screw driver into one of the rotor vents and press with all my weight...it wont move. So I decide to undo the bolts on the master cylinder to power booster. master cylinder pulls away from the booster
and I can no turn the rotors. So I went in and adjusted the push rod coming out of the booster even more than before(there's no threaded area left now). Went for a couple of laps around the block and then used my IR non-contact thermometer to check the temperature of the rotors. They measure about 200-205 degrees. I'm told thats about right.
About this truck...it came with power drum brakes(69 c10) so originally I bought a 71 Master cylinder and continued to use the old power booster. I think that was my mistake. So I will order a 71 power booster and see if that makes a difference.
While the flexible portion(rubber) of the brakes lines could suffer internal
failure...I think that is a long shot. I may change my mind but I'm going with the power booster replacement for now.
