I've been on those commercial flights where the pilot obviously landed to fast and had to slam on the brakes. The worst is when the whole airplane shutters and everyone KNOWS the pilot screwed up. Well, now that I'm flying other newby canardians around, I've noticed a bit of shuddering when breaking hard at low speeds. It's always affected the left wheel so I bought a new disc thinking the first was warped but it didn't solve the issue. So over the last couple days I've been hunting down the cause and today tried swapping the brake liners and the problem followed the liners. This tells me that a new set of liners are on order. Interestingly, the problematic liners were the ones that came from the factory with broken pads and I had to replace them. Maybe there is more to it, then just replacing the pads, but I thought it would be wise to just buy an all new set and put this issue to rest. Always something :)
