Hello all.
I picked up a 94 F150 (5.0 litre, auto, 2wd) this spring and have an unusual situation: the brakes are too sensitive! I barely have to touch them before the pedal goes down. It goes down about half way before there is any resistance. Odd thing is, the brakes work fine. (nice even skid patches on the street) Nice even braking.
At first, I thought air in the lines, so I bled them, twice. (a fluid flush couldn't hurt anyway..) On the off chance that the master is defective, I replaced that. No change. Replaced pads, shoes, drums and rotors. No change. (front calipers and rear brake cylinders were good, no leaks).
Is it possible for the brake booster to fail this way? Any other ideas?
The problem with all this is that the tiny amount of foot pressure on the brake pedal does not trip the brake switch. Thus no brake lites, and since I also tow a trailer with electric brakes, no brakes and brake lites on the trailer either. I'm worried that one day I'll be rear-ended by a semi...
Thanks in advance for your help. Mike
