Narrative:
The first officer (first officer) was the PF. He made a normal landing; and just after touchdown; he said 'I have no brakes.' he immediately applied full reverse thrust. Before I reached to turn off the anti-skid system; I tried to use my brakes and they didn't work either. The first officer released the brakes and I turned off the anti-skid (complying with the action checklist); but the brakes still did not work. I again quickly reset the anti-skid; and took over the controls; and brakes were still not available. The action checklist says that if you have loss of braking; to release the brakes; turn off the anti-skid; and re-apply the brakes. We did that; however; the brakes still did not work. When the first officer re-applied the brakes; I assumed there was a problem with the anti-skid system; which is why I reset it a second time. At this point we were going aproximately 80 knots. I continued to apply full reverse thrust until we reached taxiing speed. It was not until we slowed to a taxiing speed; that the brakes were somewhat working. I pumped them several times and I could feel that they were working; but not very well as it took a lot more force than usual. We turned left onto 4L; and joined taxiway bravo. As we were moving down taxiway bravo; the tower said there was a large amount of smoke just after touchdown. We asked if there was smoke coming from our tires; and he said no. We asked for a fire truck to inspect our tires. There were no aircraft in front of us; so I continued on bravo; as I tested the brakes a few more times. Again the brakes were working; but not the way they should. Just after the [aircraft holding] penalty box; a fire truck showed up and wanted to talk to us on a separate frequency. He said we had three blown tires; both right tires and the left inboard. I decided not to continue to the gate; and ground control asked us to pull onto mike and hold short of mike 3; I complied. I did not want to continue to the gate because braking was very limited; and it would not have been safe to be close to other aircraft or people. Once stopped; I made a PA; contacted dispatch; and maintenance control. We arranged to have the passengers bussed to the terminal; which was done within about 15-minutes. Company maintenance showed up quickly; and after further inspection; only two tires were blown and the other two were very badly damaged with deep bald spots (the left and right inboard tires were blown). Maintenance said they wanted to tow the aircraft to the gate; and asked us if we could ride the brakes; we agreed and they towed us to the gate. After much thought about the incident; I believe that all brakes were locked on landing. I do not know why the brakes were locked; the parking brake was not set; and our feet were not on the brakes. I believe the tires blew immediately on landing; and the brakes were released when I turned off the anti-skid system (which explains the jolt we felt). The action checklist says that if you have loss of braking; to release the brakes; turn off the anti-skid; and re-apply the brakes. We did that; however the brakes still did not work. When the first officer re-applied the brakes; I assumed there was a problem with the anti-skid system; which is why I reset it a second time. If I had anything to change; I probably would have just turned the anti-skid system off; and left it off. I had no way of knowing the tires had blown already; and that the loss of braking was associated with the tires; and not the anti-skid.
Original NASA ASRS Text
Title: A Captain and First Officer report about the loss of effective braking on landing in their CRJ-200 aircraft. The left and right inboard main tires were found blown and the outboard main tires had deep bald spots. No EICAS messages or fault indications were displayed in the flight deck; only a rising temperature for the left outboard brake.
Narrative: The First Officer (F/O) was the PF. He made a normal landing; and just after touchdown; he said 'I have no brakes.' He immediately applied full reverse thrust. Before I reached to turn off the Anti-Skid System; I tried to use my brakes and they didn't work either. The F/O released the brakes and I turned off the Anti-Skid (Complying with the Action Checklist); but the brakes still did not work. I again quickly reset the Anti-Skid; and took over the controls; and brakes were still not available. The Action Checklist says that if you have loss of braking; to release the brakes; turn off the Anti-Skid; and re-apply the brakes. We did that; however; the brakes still did not work. When the F/O re-applied the brakes; I assumed there was a problem with the Anti-Skid System; which is why I reset it a second time. At this point we were going aproximately 80 knots. I continued to apply full reverse thrust until we reached taxiing speed. It was not until we slowed to a taxiing speed; that the brakes were somewhat working.
