The parking brake on this 2002 Chevrolet Impala stopped working shortly after a visit to a shop. Maybe just correlation, maybe causation, I don't know..

In any case, I have taken some pictures and I don't quite understand how it's supposed to work.

Cables don't seem broken. Are the components where they should be? Anything missing?

  • Your Impala has a shoe inside the rotor for the parking brake. From your images, it appears the cables are working correctly (becoming taught when engaged). It could just be the brake shoes are worn out. It might just be they only need adjusted. Until you take the rear brakes apart, you really aren't going to know. – Pᴀᴜʟsᴛᴇʀ2 Oct 26 at 22:29
  • The cables do actuate but I don't know if it's enough to engage the parking brakes. Are the parts connected as they should be? The larger cylindrical metal part seems to be the equalizer and I don't understand why that would be attached to the nut on the cable sleeving coming from the cabin (which to my mind should not be moving) on its right side. If the brakes were just worn I would think the braking force would just be diminished, not suddenly totally absent. – adatum Oct 26 at 22:52
  • Everything you showed me in the images look like they are connected correctly. Again, I think you'll need to remove the rotors to see what's going on. – Pᴀᴜʟsᴛᴇʀ2 Oct 26 at 22:57
  • Is there anything else I can check first? I'm not sure I have the required tools or know-how to remove the rotors. A diagram of the components and operating mechanism could be helpful, as I still don't get how it's supposed to work. Specifically, where is the equalizer supposed to be attached? – adatum Oct 27 at 0:04
  • When you say they don't work what exactly do you mean? They don't stop the car or they don't release? What work was recently done? – GdD Oct 27 at 15:31
