Today I pulled my A12 out making way for the L series after alot of oh F#$%! and the ol' A series was out then i went to push my car out of the shed to clean the filthy oily mess I made on the floor and the brakes had seemed to built alot of pressure i tryed everything but its still got strong pressure the pressure is on and off so it would roll then lock suddenly what the hell i even checked if i had crushed any brake lines while pulling the A12 out but nothing not even a bent one whats going on guys i really need help if anyone can explain to me or help me out that would be great its got me stumped.
