I'm installing a line lock on my 86 GT. Right now, I have it mounted pretty high up on the driver's side fender. It looks to be positioned higher than the Master cylinder. Am I going to have problems with air trapped in the line after bleeding?
Yep, you'll have air trapped there. Just bleed the system normally, then crack the line at the linelock to let the trapped air out at the highest point while holding a bit of pressure on the brake pedal. You want fluid moving out while you tighten the lines back.
