I changed the front brake pads on the LITTLE RED ROCKET around 100,000 miles.
The posting can be found at:
Mods. and tech. issues, TURBOCHARGED INSIGHT, page 14 I believe. In my opinion, 100,000 miles on any brake pads is enough even though the thickness indicated that that many more thousands of miles were available.
Even though you may not need new pads/shoes, bleeding the brake lines and adding new fluid will help to extend the life of the brakes. Old brake fluid can gum up the cylinders causing them to stick, thereby wearing down the brakes and decreasing mileage. Also, if the bleed valves aren't excercised occasionally they can sieze into the caliper, necesitating caliper replacement. Just a thought from someone who hasn't taken his own advice often enough in the past and paid the price. I really, really want to do better with this awesome car.
My 2000 Insight has 80,000 km (50,000 miles) I checked my brake pads 2 weeks ago. My front pads have about 60% material left (compared to new pads). That's after over 10 days of auto slalom racing and 3 days of lapping at race tracks.
I use Motul 600 synthetic high temp brake fluid.
