Narrative:

After touchdown in ZZZ xxl brakes were applied at approximately 80 KTS. A slight shudder was felt. Upon exiting runway at taxiway P noticed brake temperatures of #1 60; #2 250; #3 60; #4 60. Cleared to cross runway xxr on taxiway P. Right after we exited runway xxl. When we cleared runway xxr on taxiway P turning on taxiway north brake temperatures were #1 180; #2 455; #3 160; #4 175. The plane required a larger than normally amount of power to taxi. We suspected a stuck brake and stopped on taxiway north. We called maintenance and they told us not to taxi and they would have a mechanic come out and either remove the tire or deflate the tire and have us towed in. Mechanic came out and deflated tire and station operations towed us to the gate. Mechanic said it appeared that there was some time of bearing problem and the brake was grinding metal.

Title: AN A320 WITH AN APPARENT WHEEL BEARING FAILURE DEVELOPED A HIGH BRAKE TEMP AFTER LNDG AND WAS TOWED TO THE GATE.

Narrative: AFTER TOUCHDOWN IN ZZZ XXL BRAKES WERE APPLIED AT APPROX 80 KTS. A SLIGHT SHUDDER WAS FELT. UPON EXITING RWY AT TXWY P NOTICED BRAKE TEMPS OF #1 60; #2 250; #3 60; #4 60. CLRED TO CROSS RWY XXR ON TXWY P. RIGHT AFTER WE EXITED RWY XXL. WHEN WE CLRED RWY XXR ON TXWY P TURNING ON TXWY N BRAKE TEMPS WERE #1 180; #2 455; #3 160; #4 175. THE PLANE REQUIRED A LARGER THAN NORMALLY AMOUNT OF PWR TO TAXI. WE SUSPECTED A STUCK BRAKE AND STOPPED ON TXWY N. WE CALLED MAINT AND THEY TOLD US NOT TO TAXI AND THEY WOULD HAVE A MECH COME OUT AND EITHER REMOVE THE TIRE OR DEFLATE THE TIRE AND HAVE US TOWED IN. MECH CAME OUT AND DEFLATED TIRE AND STATION OPS TOWED US TO THE GATE. MECH SAID IT APPEARED THAT THERE WAS SOME TIME OF BEARING PROB AND THE BRAKE WAS GRINDING METAL.
