Yes she is an 8 lug 4x4... So far I am pretty happy with her, but people out here seem to drive as if someone is chasing them, thus brakes are a high priority. When pressing the brakes it takes about 4-5 car lengths to slow down.. If someone jumps in front of me atm I would more than likely not be able to stop.. The PO(my uncle) assumed it was normal behavior, but it doesn't seem quite right to me..

What commonly happens is old cars that have been sitting awhile with moisture in the brake fluid and both pistons of each wheel cylinder are not moving (one gets frozen) so only one brake shoe is moving and not both. Pretty soon the one shoe starts to wear very quickly and there isn't enough travel left in the linkage to take up for the worn brake shoe. Or the drums have been turned too many times and there isn't enough travel in the brake linkage to engage the drums when the shoes are half worn.

Thank you for this.. It does seem as if pistons are frozen.. Is there a way to unfreeze them or am I better off purchasing new ones?
