EMB ERJ 170/175 ER/LR
Flight Crew Air Transport Pilot (ATP)
Aircraft Equipment Problem Less Severe
General Maintenance Action
Aircraft; Procedure
We had brought this aircraft in and had written it up for the same messages. We stayed at the hotel and on the second day were told it was fixed and ready to be repositioned. When we arrived at the aircraft I asked the mechanics what they did to fix the issue. They said they did a lot of trouble shooting; replaced some wiring; did a gear swing; replaced some valves; and did a service check. I verified the logbook had closed the write up; service check and airworthiness were valid.Once they left we took off after a short storm delay. About half way to destination the RH and LH BRK FAULT messages appeared. We ran the QRH and planned for a flaps FULL landing. We prepared for asymmetrical braking and the possible use of the Emergency Parking Brake. Because both the RH and LH BRK FAULT messages were present we concluded that there would be a 50 percent loss of braking. I decided that I should do the landing in the event that the Emergency Parking Brake needed to be used. We contacted dispatch and let me know of the messages and status. We decided to continue and that the runway there was of adequate length. Upon touchdown I notice the brakes did not have their normal braking power. We exited the runway with no problem. We stopped to assess the brakes. The inboard brakes were at ambient temperatures while the outboards were slowly rising. By the time we got to the gate; one outboard was just above the line in the yellow while the other was just below the line in the green. Once the aircraft was shutdown I contacted maintenance and wrote up the messages.I think a maintenance flight needs to be done with this aircraft. I don't think it should be in revenue service with this problem reoccurring and the fact that it is a new aircraft. After writing this up a second time and the 8th or 9th time overall; I don't think we should be landing with 50 percent brakes with passengers onboard until the issue can be permanently resolved.
An EMB175 Captain experiences a RH and LH BRK FAULT message on a reposition flight after Maintenance had attempted to correct the same fault from the previous flight. The reporter states that this is the eighth or ninth time this aircraft has been written up for the same fault and the aircraft is almost new.
