B737 Next Generation Undifferentiated
Aircraft Equipment Problem Critical
General Maintenance Action
Aircraft; Human Factors
Normal landing; when autobrakes engaged at wheel spinup; I felt stronger than normal braking. When disengaged and subsequent manual braking; brakes seemed to stick then release. Kept both engines running to gate. After inspection; found Brake Assembly at right Outboard [Main Landing Gear] truck disintegrated.
Reporter stated the B737 Next Gen aircraft was on a quick turn when they picked-up the aircraft in ZZZ. Maintenance had just signed-off a problem involving the brakes that had been noted by the inbound flight crew. On his arrival in ZZZ1; during the landing rollout the braking action was not smooth during auto braking or manual braking. He decided to taxi to the gate rather than sit on the ramp until Maintenance arrived due to possibility of the brakes locking up if they had overtemped. Their B737 Next Gen aircraft do not have Brake Temperature indicators.Reporter stated he looked at the right Main Landing Gear (MLG) with one of their Mechanic's who said the outboard carbon fiber brake had disintegrated. The Main tire was not flat; but was canted outboard at the top with the Wheel Spin Canon plug hanging out from the axle; the brake was really chewed-up. An outboard bearing for the Main wheel/tire assembly was believed to have failed. The tire sidewall was worn. The aircraft was taken out of service and sent to the hangar.
Captain reports that during landing rollout when the autobrakes engaged; the braking was stronger than normal on their B737 Nex Gen aircraft. Brakes seemed to stick then release; when in Manual braking. Right Main Landing Gear (MLG) outboard main tire was found canted outboard with Wheel Spin Canon plug hanging out and brake disintegrated.
