Aircraft
We commenced our takeoff normally. At around 95 kts; we got an ECAM for Y RSVR Lo Lvl and Y RSVR Lo Air Pr. The Captain initiated the abort with a max speed of approximately 100 kts. All callouts and notifications were made and we were able to taxi clear of the runway and stop. ATC notified us that we had trailed smoke so we asked him to roll the ARFF (Aircraft Rescue and Firefighting) equipment. We ran the rejected takeoff checklist and then ran the ECAMs of which there were several all relating to the hydraulic issue. ARFF indicated that we had dumped a lot of hydraulic fluid. We were towed to the gate for repairs and offloaded the passengers and bags.
Received a Master Caution light and ECAM during takeoff roll on Runway XXR at ZZZ and accomplished a rejected takeoff. The Master Caution and ECAM occurred at approximately 95 kts and Reject initiated between 95-105 kts. During the reject; several ECAMS displayed indicating loss of the Yellow Hydraulic system reservoir and Yellow system air pressure. At slow speed and with normal brakes and nosewheel steering available; I opted to take high speed Taxiway XX to safely clear the runway and bring aircraft to a full stop while the First Officer coordinated with Tower controller to roll the AARF (Aircraft Rescue and Firefighting) equipment as Tower stated they saw what appeared to be smoke trailing from the number two engine. While awaiting AARF response; we ran the Rejected Takeoff QRC and handled the ECAMS; started the APU and communicated with the passengers [and] inflight crew. After AARF arrival and initial inspection; we shutdown the number 2 engine with AARF on scene; then chocked the gear and shutdown the number 1 engine which had been used to keep normal brakes available. We coordinated with Operations and Ground Control for uneventful tow back to the gate for repair.
A320 Flight Crew reported a Rejected Take Off when the Yellow Hydraulic system showed low quantity and had to be towed back to the gate.
