Replacing the Parking Brake Cable on Your 1979-1997 Buick Century
A complete guide to diagnosing, buying, and replacing the parking brake cables on your classic Buick Century.
- The main causes of failure are rust, seizing, and stretching due to age.
- Dorman is the primary aftermarket brand available; quality is generally adequate but check for correct fitment.
- Your Century has a multi-cable system (front and two rear) that may need to be replaced individually or as a set.
- Replacement is a feasible DIY job for those comfortable working under the car, but rust can make it challenging.
Is Your Parking Brake Cable Failing?
The parking brake cables on an older car like the Buick Century are prone to failure from age, use, and corrosion. Because they run underneath the car, they are exposed to water, salt, and road debris. Over time, the cable can rust inside its protective sheath, causing it to seize up, or it can stretch, making it ineffective.
Common Symptoms of a Bad Cable:
- Loose or Spongy Pedal: The pedal goes to the floor with little resistance, and the brake doesn't hold. This usually means the cable has stretched or snapped.
- Parking Brake Won't Hold: Even when the pedal is fully depressed, the car will still roll on a slight incline.
- Brake Won't Release: You release the pedal, but the brake remains partially engaged. This is often caused by a rusted or seized cable and can feel like the car is dragging. You might also notice a burning smell from the rear brakes after driving.
- Parking Brake Light Stays On: If the pedal doesn't return to its fully released position, the warning light on your dashboard may stay illuminated.
A Note on Recalls and Service Bulletins
Searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any specific recalls or Technical Service Bulletins (TSBs) for the parking brake cables on the 1979-1997 Buick Century models. Any issues you experience are most likely due to normal wear and tear over the decades.
Choosing the Right Aftermarket Cable
For a vehicle of this age, finding original equipment (OEM) parts from GM is highly unlikely. The aftermarket is your primary source for a new parking brake cable. The most widely available brand for this part is Dorman.
About Dorman Parking Brake Cables
Dorman is a common choice for replacement parts on older vehicles. Their cables are designed to be a direct replacement and are generally affordable. They feature sheathed and lubricated inner cables to help prevent corrosion. However, owner experiences can be mixed. While many install them with no problems, some mechanics and DIYers report minor fitment issues, such as needing to file a connector or finding the length slightly off. Despite this, they are often the only practical and available option.
OEM vs. Aftermarket Quality
While an original GM cable from the 1980s or 90s might have been of higher quality, they are no longer in production. For a part like a parking brake cable, an aftermarket Dorman cable is a perfectly acceptable replacement. The most important factor for longevity is ensuring the cable is routed correctly and not binding, and that the brake hardware it connects to is in good working order.
Parking Brake Cable Replacement Costs
The Buick Century uses a multi-cable system. You may need a front, center, or rear cable, or a full set. Prices for individual aftermarket cables are very reasonable.
| Part Type | Estimated Cost |
|---|---|
| New Aftermarket Cable (Dorman) | $29.64 - $48.03 (per cable) |
| New OEM Cable (GM) | Discontinued/Extremely Rare |
| Shop Labor | $150 - $300 |
Frequently Asked Questions
How many parking brake cables does my Century have?
Most 1979-1997 Buick Century models use a three-cable system: one front cable from the pedal to the center of the car, and two separate rear cables that go from the center to each rear wheel. You must identify which cable has failed, though it's often wise to replace them all if they are original and rusted.
Can I just adjust the cable instead of replacing it?
If your cable has only stretched slightly over time, an adjustment may be possible. The adjustment point is typically on the equalizer where the front cable meets the two rear ones. However, if the cable is seized from rust, frayed, or broken, no amount of adjustment will fix it and replacement is necessary.
Is replacing the parking brake cable a difficult DIY job?
This job is considered moderately difficult. It doesn't require many special tools, but it does require safely lifting and supporting the vehicle on jack stands. The biggest challenges are often dealing with rusted bolts and clips underneath the car and potentially disassembling the rear drum brakes to attach the new cable.
What is an equalizer?
The equalizer is a simple metal bracket that connects the single front cable to the two rear cables. Its job is to 'equalize' the pulling force so that both rear brakes are applied with the same pressure. These can also seize up with rust and are sometimes replaced along with the cables.
Technical Specifications
System Type: Mechanical, foot-pedal operated. Configuration: Multi-cable system typically consisting of one front cable, an equalizer, and two rear cables connected to drum brakes.
