The brakes on my M35A2 are grabbing.
If slowing the truck using the brakes only from, say, around 10 or 15 mph, when I step on the brake pedal the pedal goes down a bit and then has high resistance, with no application. Press harder, and all of a sudden the brakes grab and the truck literally stops on a dime.
It is like I cannot modulate the brake pedal when coming to a stop.
Then, the pedal does not want to return up. When starting in gear, when the brakes are cold they are not released - I can get them to release by reapplying the brakes and lifting the pedal with my foot. Once the truck starts rolling they also release.
I have not tested this stopping from a higher speed due to not having a safe place to try this (and not wanting to risk flat spotting 6 tires).
The master is topped off with DOT 5. One thing I know for sure is that the brake return spring is totally rusted and must be replaced. I would have replaced it already but I am in the boonies at the moment; no auto parts stores around.
I figure that all of the problems are being caused by a totally slim shadied brake return spring, and I plan to replace it at my earliest opportunity (200 miles from now).
The reason for this post is to get some additional opinions on what this might be in case I need to dive deeper into this brake system.
Thanks in advance.
