Analysis

After touchdown the plt applied brakes to slow the acft in order to turn off the mid-field exit, but the acft was going too fast for the turn. The plt stated he felt the brakes begin to be ineffective at this point. He then decided to let the acft roll to the end of the rwy. The brakes would not hold when he applied them near the end. The plt then added full power in order to pancake the acft into the lake off the end of the rwy. The acft struck the water 75-100 yds from shore. The brakes were examined & the brake system was capable of operation. However, both brake disks were worn beyond allowable limits. The left disc measured 0.403 inch & the right disc measured 0.401 inch. Minumum is 0.445. In addition,the discs contained 'blue' spots on their surface indicating that they had been severely overheated during the landing.
