Although the scoreline suggests an easy win for Brig, the game was very much in the balance at half-time with the scores level at half-time.
However, Brig pulled away after the interval, running in six goals against the Northern League outfit.
It was Matt Dudley who opened the scoring after 20 minutes, meeting a Ryan White cross with a firm header.
However, the visitors’ performance turned sloppy and their hosts equalised courtesy of Regan Paterson on 35 minutes.
Sheldon Green had gone close a couple of times but Brig boss Jamie Milligan needed a big response from his players in the second period and he got it.
Craig Carney nudged his side back with a deflected effort on 57 minutes and a few minutes later Ewan Bange swept the ball home after a great move involving Cameron Gourley and Matt Thompson.
Green made it 4-1 when he headed across the keeper from a Luke Higham free-kick and the game was up for the hosts soon after when Carney rounded the keeper to slot home.
A great dribble by Rob Apter in the 79th minute ended in him slotting the ball into the corner and the scoring for Brig was completed when Green fired home just a minute later.
Mikel Thompson scored a consolation goal in the last minute.
Elsewhere in the cup, a solitary strike from tom Kilifin saw Lancaster City edge past Northwich 1874 at Giant Axe. Kendal Town, though, were beaten by a similar scoreline at home to Warrington Town.
Clitheroe’ s interest in the competition came to an end after they were beaten 1-0 at City of Liverpool.
