You can make them last longer if you use them togeather, on a straight line stop from any speed apply the rear brake first then the front. your rear brake keeps the bike headed in a straight line but your front give you the most stopping power. Lyndall makes great replacement pads over the stock.

 

Just had the 10,000 mile service done on my '10 Heritage Softail from the local HD dealership. Rear pads replaced.

 

I got only 11k on the back, but the fronts look good to at least 20k. Funny thing is I don't even use the back that much, only when I need some extra braking

 

Like the others have suggested, depends greatly on the rider's braking methods.

I've ridden with guys that do full panic stops at every light...for some unknown reason, they burn up pads in a couple thousand miles.

So, that's why you do the little inspections every once in a while...when it's time to replace them, replace them. Should take about 15 minutes to replace the rears and a little more for the fronts.

 

I always replace the rear pads when i do the tire which is around 10k for the rear. They are down to about 25% at that time. Fronts go about 20k for tire and pads.

 

I just replaced the stock pads at 15,000 miles.
Wanted to try the Lyndall Z+ pads front and rear , the stockers were noisy and dusty.
I'd say the rears would have gone 20-25,000 and the fronts maybe 18,000.
I'm a pretty conservative rider , so I usually get pretty good mileage from all my vehicle brakes.
I do like the Lyndalls , a bit smoother and quieter , plenty strong braking , nice feel also.
