Scratch Scratch scratch...
Well that was the sound my drum brake on the drivers side made today when I took it out to get some lunch for the family. I also noticed that when I let off the gas and shifted into neutral, the car slowed and came to a less than smooth stop. Meaning it felt like the brake was dragging. To test this theory, I put it in first and let the clutch out slowly without giving it gas. THe car will die before it is able to move it under its own power while idling.
There was also a lovely smell coming from the rear of the car like pads overheating.
So, I got it home,
Pulled the wheel off
disconnected the E-brake cable
rotated the drum so the inspection hub hole was over the wheel cylinder
Loosened it up until the drum easily rotated. Since I just put pads on there about 500 miles ago, I greased up the hole in the drum and the guide edge on the axle and it just poppet right off. Lovely.
now the mystery comes in. The drum was full of dust, so it was dragging. Now I have to decide if it was dragging due to one of two things.
1) worn rear bearings allowing the rear axle to droop and touch the pads, I do not think this is it, as it was going scratch scratch scratch as the wheel turned, indicating that there was a high/low spot, if the bearing was bad it was just grind and grind constantly. However, when I grab the wheel studs and move them back and forth and up and down, I cannot see or feel it move no matter how hard I look, but I can hear a faint click as I move it side to side. It takes about 2.1 lbs of force to turn the axle so that is about right, and it spins smooth as silk. My gut tells me it is not the bearings although I have NO idea when and if they were ever changed. My car has 70900 miles on it.
2) bad wheel cylinder hanging up from being stored for a while and sticking. When I redid my brakes, I did not change the wheel cylinder as it looked fairly good. Now I do not know. Is there a test I could do on the wheel cylinder, or should I just replace it. By the way, the passenger drum spins beautifully, this is only the drivers side. When I stomp on the brakes the scratching sound stops and but the sticking is far more pronounced.
Advice is needed. Me thinks it is a sticking wheel cylinder... but I would love to hear opinions.
I know I need a brake vacuum booster, now I may need a wheel cylinder.
