Re: Drum Brake Problems

I'd say you have some wheel cylinders that are rusting on the inside. Mine exhibited the same symptoms, then started to leak so I replaced what looked like new cylinders. I pulled them apart once the job was done to see what was going on inside, and they were coated in a crystal rust. Locked them up tight!

If it were my truck, I'd replace the 3 remaining wheel cylinders. They're not bad in cost, just not fun to replace.
