I know there isn't a set time... but I've only owned one car that had 4 wheel disk brakes and they lasted longer than a car with disk in the front/drums in the rear.
The merc is the first car I've had that was 4 wheel disk with traction control and anti lock.
On my wife olds, I changed the front disks/pads every year (aprox 30K miles) and I've changed the rear drum pads once in the 130K I've put on it. Except for the last time I did it, I bought the high dollar pads and they for some reason kept the disks from warping and have lasted 2 years so far, but it hasn't been driven the past year except around town.
I just didn't know that if cars with 4 wheel disks tended to last longer in general. Also, with it being an "old guy" car that maybe it had a different type of pads on it to last longer as well.
I do the work myself and since I have a carport vs a garage and the weather sucks, I was going to put it off for awhile. But my brake light came on yesterday when I was cut off in traffic and jammed on them. The light came on for a sec, then shut off. I added some brake fluid today since it the resevoir was only about 1/3 full. My guess on the loss of fluid is because the pads are worn and the fluid is taking up the extra space in the caliper cylinders.
Sorry, didn't mean to thrash your pro-long thread...
If its about cars it all good with me!
