Stiff pedal/Hard Brakes
I have been noticing my brakes getting weaker and weaker through the life of my truck. The pedal is very stiff and seems to not be stopping the truck very well anymore. My buddy has a 2002 7.3 powerstroke that has much better brakes than mine so I suspect I have a problem somewhere. I initially thought my rotors may have been glazed over so I replaced all 4 rotors and pads. This did not seem to have much affect. Does the brake fluid or power steering fluid go bad or weaken? The truck has 155k on it and I do not think either have been done ever. My other thought was a bad vacuum pump, brake booster or a vacuum leak. Can anyone point me in the right direction for typical problem areas for this problem?
