There are typically two forms of park brakes used on disc-equipped cars or trucks: One type is engineered so a miniature drum brake system mounts within the rear brake rotor. The brake shoes incorporated in this system connect to a lever that is engaged by the park brake lever or foot pedal.
Consequently, how much does it cost to fix the emergency brake?
You actually don't need professional help to replace the emergency brake cable. The cable itself usually costs $10–$20, depending on the make of your car. This is the only cost that you will incur assuming that all other components of your brake system are in good condition.
How does the electronic parking brake work?
A traditional handbrake is very simple – pull the lever up and you pull two cables which run to each of the rear brakes. Put simply, an electronic parking brake replaces this mechanical system with an electrical one. By pressing the switch, motors on each brake caliper squeeze the pads into the disc.
What happens if you drive your car with the emergency brake on?
When you drive with the parking brake even partially on for several miles, it's possible to warp a drum or disc. Or if the brakes get really overheated, you can even cause the lining's adhesive to fail, and have the linings crack or even separate from the pads or the brake shoes. And that would need to be fixed.
