Hi all,

I have a new noise that's quite concerning. When I first start accelerating after the engine's been off for a while, I hear this low, groaning noise that sounds like I'm driving with the parking brake on (I'm not). It makes me wonder if something is rubbing because it doesn't seem to accelerte as easily. It only happens with acceleration; not idling. Also seems to be vibrating more then the usual amount of annoying vibration. It only happens the first few accelerations, then goes away. The faster I accelerate, the higher pitch the sound gets. It only happens after the car has been sitting idle for a while; with or without the hand brake on. Lot's of possibilities as to the problem I'm guessing. Any thoughts?

Thanks

Hi Chari,

Here's a thought.

Last week-end I changed the oil and rotated the tires. I noticed that the R rear wheel was not turning freely--as if the handbrake were barely on. I checked the lever and it was not engaged. Also, the L rear wheel turned freely.

Upon closer inspection I noticed that the R handbrake cable had about 4 inches of the rubber sheath torn away and the outer metal cable was covered with rust. So, I soaked it with PB Blaster, worked the lever a few times and flexed the cable. Finally, the drum brakes released.

So I then adjusted the shoes on both sides. I also wrapped the tear with 3-M vinyl tape.

I believe the sheath was torn several months ago when the tire blew on that wheel and the sidewall scraped the cable. It probably took water and salt to corrode the cable.

I hope this helps,

Bryan
