Brakes Sticking

Post by Darbronnoco » Sat May 13, 2017 4:41 pm

I woke the beast up from its winter slumber and on my test drive I noticed that my brakess seemed to be dragging a bit. The brakes would stay somewhat engaged after applying and feel a bit soft at that point. I could lift up the pedal with my toe and it would stop dragging. If I give the brakes a few pumps it feels like I have good pressure. My thought is that it could be a semi blocked compensating port. I don't see any obvious leaks and break fluid level looks fine. Everything was fine before storing this winter in my garage. Hoping for some ideas and things to check from the wise sages/asses here. Thanks!

Is the brake pedal lever sticking due to rust? Pull belly pan and pull down on the lever that the pedal bolts to. If it is difficult to pull and stays down even, you need to free up the pivot with penetrating oil followed by as thorough a lubrication as you can muster.
Is your booster not releasing?
Any dampness at the wheels?

I concur that either the position of the pedal, due to rust, stiff grease, weak or broken pedal return spring, booster, or master is causing, as you put it "semi blocked compensating port." The other possibilities are swollen brake lines, or delaminated brake lines that allow fluid to flow easier to the brakes than return.

It's most likely a booster or pedal linkage issue. There are about 6 springs in the various mechanisms involved all tending to return
the brake pedal to it's fully undepressed position. It should rise fully and rest against the rubber stop pad on the underside of the
cab floor. When so situated, there should be no pressure between the pedal linkage and the booster actuating rod. It's an easy thing
to check.

Thanks for the feedback. Hopefully I can get a break (no pun intended) from this thphoon weather so I can get a better look.
