I own a 1972 FJ-40 with drums all around. I recently had a problem with my passenger front brake dragging and almost locking up on the road. Since then, I had all the drums machined, and installed new shoes and springs.
The brakes work great, however, I've noticed that the passenger side will start getting tight again after several trips around the block. I adjusted them a few clicks looser, but the problem will return after another drive.
From what I've read here on MUD, I've narrowed the problem down to a few culprits. One, the brake hose may be defective. While bleeding the brakes, I noticed that very little fluid gets past the bleed screw, even when using my power bleeder. I believe these hoses may be original.
Or, the wheel cylinders are not retracting back fully. While replacing the shoes and hardware, I didn't notice any signs of leakage at any of the wheel cylinders.
The master cylinder/booster was replaced about a year ago, and I've checked the push rod length and pedal height. The driver's side drum does not have this problem. I'm at a loss at what to do right now, and I don't want to throw parts at it aimlessly.
Could you give me some advise on how to determine what is causing my front passenger drum to tighten up? Any help greatly appreciated.
Mahalo,
