On my 98 1500 I have never really had to "hit" the brakes hard until the other day when some deer ran out in front of me. They felt very WEAK!! The pads are good, and the oil is up, does anyone know how to make them work better.
I agree with Grey Bear, check the rear shoes. Then I would bleed the system. Quick question, have you changed the fluid recently? When fuild get old it absorbes moisture and that lowers the boiling point. Without the ability to absorb brake heat, the pads and shoes wont be able to shed their heat and that will lead to longer than normal stops. Keep us posted. Good luck... Chris
First try adjusting the back brakes, you can do this by going in reverse and braking many times. The best way is to do it manually, behind wheel theres a little slot, were you can adjust them if you have a screwdriver. If its not the adjustment, then i would check your master cylinder, its not uncommon for them to go out, and if they are out, you will notice the peddel squash to the ground when trying to brake. i just ordered a upgrade kit for my truck, but ill tell ya once you adjust the brakes, it makes a huge difference. i couldnt stop my truck worth crap when they wern't adjusted. Ill post a review of my kit once i get it installed and tested.
