1995 F150 Can't Bleed Air Out
I have a 1995 F150 4x4 with only 47,000 miles. A few weeks ago the left front steel brake line from the MC down to caliper rusted through. I replaced both that line and the line going across the front to the right side as it was suspect as well. Since then I have put no less than 3 quarts of brake fluid through the system trying to get rid of a soft pedal. I know at one point I may have let the reservoir go dry, but since have thoroughly bled both front and back lines using the typical RR, LR, RF. LF cycle. I bled the ABS valve and even cracked the front line at the MC while under pressure to try to bleed the MC. Am I missing something? I hear an airlike, squishing sound when I push the pedal down while the truck is running. Pedal will seem hard if no boost is applied(truck off). Thanks.
