Hi Guys,

For the past while I have noticed that I don't seem to have a full brake pedal. I don't feel and sponginess nor do I feel the pedal drop to the floor with constant pressure.

My first thought was perhaps my rear brakes were not self-adjusting. The weird part is that sometimes I will have a full pedal, and then I am back to half a pedal.


The vacuum brake assist diaphragm and check valve are holding vacuum overnight and my brake fluid level is stable.

I have noticed that I am nearly due for new pads and rotors up front. They are fine now, but running a bit low.

I am getting ready to drive from D.C. to Alaska and would sure like this issue resolved. The truck stops just fine, I just don't have the full pedal like I used to.

Any ideas please

I'd check the self adjusters again. Thats what caused this condition in my truck.

I think your rear brakes need to be adjusted outwards. You say sometimes you have a full pedal, and this could be because you pumped the shoes out to the drums if you were using the brake, but then if you stop using the brake the shoes spring inwards away from the drums, and next time you hit the brakes theres a big gap for the shoes to travel before they make contact. Adjust them out and they will always be right up against the drums.

I'd also try bleeding the brakes, as its easy and quick.

stupid question, but u didn't have the e-brake on or anything?

This same thing has been troubling me for the last couple of months, accept worse. Come to find out the spindle nut on one of the wheels was loose, causing the disc to have the slightest bit of play and causing the caliper to push in.
