Narrative:

I was the pilot monitoring from ZZZ to ZZZ1. During the preflight planning phase; it was noted that the current MEL/cdl item for aircraft was deferred using [a] MEL; which made all autobrake functions; including rejected takeoff inoperative. The deferral had been entered to address a write-up that read 'after touch down EICAS message autobrakes and aircraft left centerline to the left'. Our taxi to runway xxl in ZZZ1 occurred at normal taxi speeds and no malfunctions were felt or noted. Upon being cleared for takeoff; we performed a rolling takeoff with all engine and system indications normal. At approximately 90-100 knots; a momentary brake application was felt; with a similar application felt approaching rotation speed. The application was momentary and controllable with normal flight control inputs. We had two cockpit jumpseaters; in addition to the captain and myself. All four of us felt the momentary application/slight deceleration and verbally identified it. Once airborne; our climb out; cruise; descent; and approach phase were all normal. During the cruise portion of the flight; the captain coordinated with dispatch and technical support maintenance control; as well as requesting emergency equipment standing by on our arrival into ZZZ. During the approach briefing; we discussed the importance of not floating the landing; as well as using all available resources (spoilers/reversers/brakes) to stop the aircraft in as controlled a manner as possible. We flew a normal ILS xyr in ZZZ; with [priority]. The landing was normal; with the momentary application of the right brake being felt during the rollout. During the landing; although the auto speedbrakes were confirmed armed; they did not automatically deploy. The EICAS indicating the failure was verbalized and the captain manually deployed the speedbrakes. Upon clearing [runway] xyr; ATC was coordinated with and advised that no further assistance was required. We taxied normally and shutdown at gate. Upon arrival at the gate; we debriefed with 3 maintenance personnel; input the appropriate elb reports; and debriefed with two pilots from the [chief pilot office] regarding our assessment of the event. Finally; we completed our post-flight debrief and continued the remaining portion of our [trip].

Title: A Boeing 757 flight crew reported braking problems during takeoff and landing.

Narrative: I was the Pilot Monitoring from ZZZ to ZZZ1.
