1986 F150 had a leaky wheel cylinder which ran master cylinder dry. I refilled master cylinder, wheel cylinder and washed brakes down with brakekleen and then sanded drum and pads and then bled rear brakes. The pedal seems very hard, brake booster and master cyl. less than a year old. Check valve on booster works good, no leaks that I can hear and plenty of vac. What am I missing.

What exactly is the problem? It sounds like you had a problem, fixed it, and now everything is working fine. Is something still wrong?

F150 brake pedal too hard

The pedal is too hard. It seems like I have a blockage because it's stopping poorly. I did not bleed the master cyl. but did bleed the rears with no problem.

Did you replace your wheel cylinders? I hope so.

I don't know how well any brake cleaner will work on removing brake fluid that has soaked
into brake shoes but that's a different issue.

Concerning your pedal, I'm gonna suggest bleeding all 4 wheels, not just half of them

Yeah, i would also suggest bleeding all four brakes. Make sure you start with the one furthest away from the master cylinder also.

If your by yourself you can just air bleed them.
