I have a 1998 Chevrolet Cheyenne, 44,130 miles, 3500 1-ton 4x4 with duals, and a flatbed. The brake pedal goes to the floor with no resistance. Pedal does not like to come back up after it is depressed. Here's what we've done thus far:
1. Replaced the brake lines and bled all four wheels.
2. Replaced the master cylinder after a bench bleed.
3. There are absolutely no visible leaks on the brake lines, attachment points, or on any wheel.
4. We've tried pumping the brakes. We pump the brakes six times, apply light brakes, and start the engine. All of this is futal because the brake pedal goes to the floor with no resistance.
5. The truck came from back East (Georgia) and is exceedingly rusty on the undercarriage.
What's next? Should I replace the boost or replace the wheel brake cylinders which might be bypassing brake fluid? Is there anything I have not considered?
Thank you in advance for reading this post and for any response or opinion you care to offer.
Kindest Regards,
