Caliper O-Ring started to leak at 1,000 flying hours. Replaced one side and within 2 weeks, other side was leaking.
3 other RVs in the SoCAL Wing of Van's Air Force have had the same kind of problem around 5 years or 1,000 hours of operation. One RV-8 put the puck in BACKWARDS then did the recommend brake lining conditioning with a high speed taxi. Needless to say, the puck came out far enough that he got 5606 on the hot disc and had a fire. Ground Control radioed the aircraft. Back at the hangar, the pilot's son put the fire out with the hangar fire extinguisher. The fire was right below a full fuel tank. Wheel pants and brakes were replaced.
On my airplane, I plan to replace O-rings every 5 years or 1,000 flying hours. DO NOT do brake lining conditioning per the recommendation that comes with the lining. RVs are much lighter than the FACTORY airplanes that the brakes were designed for.
