Mushy Brake Pedal

Mushy Brake Pedal
I have a 98 Lariat with the 5.4l, 2wd. My brake pedal is very mushy, and has been getting worse and worse. I just changed the pads and bleed the brakes, but this did not change anything. I have also had the rotors turned twice in their life. When I was searching for previous threads, I saw that someone mentioned something about a TSP recall on the brake booster, but I could not find anything on the NHTSB website. Does anybody have any suggestions? I hate taking my truck in to the shop because I always feel I am getting ripped off, I just need some suggestions because Im stuck on what to do now. Thanks- Dave

Mushy Pedal
I have the same mushy pedal issue. I've replaced rotors (raybestos) and drums, new bendix pads and shoes. Replaced right rear bleeder screw and bled everything three times. No Luck, my pedal still travels quite a bit. I'm gonna try to bleed the front lines again.
Haven't looked at brake booster yet.

The brake booster TSB is not for a mushy pedal, it is for inadequate braking with a heavy load/trailer. They replace the F-150 booster with the one from the F-250. A mushy pedal could be low brake fluid, leaking wheel cylinder, leaking caliper, bad master cylinder, or contaminated/air in the brake fluid.
Good luck

Somtimes the pedal feels mushy if the rear shoes are out of adjustment. Also, the material of the pads can make a difference too.
TexfordD has a good point, in the past I had replaced the rubber brake hoses on sports cars with the braided stainless steel hoses and noticed a definete improvement in pedal feel. I'm not sure everyone wants to shell out that kind of $$$$$ for three hoses though.
