Is Your Pontiac a Tempest or a LeMans?
A critical point for owners of 1977-1981 Pontiacs: The Pontiac Tempest was not produced for the North American market during these years. The original Tempest line ended after the 1970 model year and was replaced by the Pontiac LeMans. If your vehicle is from 1977, 1978, 1979, 1980, or 1981, you almost certainly have a Pontiac LeMans or Grand LeMans. It's a common point of confusion because of the shared history of the two models. Before buying any parts, confirm your vehicle's model name on your ownership documents or vehicle badging.
Symptoms of Failing Drum Brake Hardware
The small springs and clips in your drum brake hardware kit are under constant tension and heat. Over time, they can weaken, rust, or break. This can lead to serious braking issues. Here are the common signs of failure:
- Scraping or Grinding Noises: If a spring breaks, a brake shoe can drag against the inside of the drum, causing a constant scraping sound. This is different from the squeal of worn-out shoes and happens even when you aren't braking.
- Weak or Ineffective Parking Brake: The parking brake on these cars uses the rear drum brakes. If the hardware is weak or broken, the shoes may not press firmly against the drum, causing the parking brake to feel loose or fail to hold the car on a hill.
- Reduced Stopping Power: Worn-out hardware can cause the brake shoes to sit incorrectly, leading to uneven contact with the drum and less effective braking.
- Brake Drag: Weak return springs may fail to pull the brake shoes fully away from the drum after you release the brake pedal. This causes constant friction, which can lead to overheating, smoke, and premature wear on your brakes.
Choosing the Right Aftermarket Kit
New Original Equipment Manufacturer (OEM) parts for these vehicles are no longer available. All new replacement drum brake hardware kits are produced by aftermarket companies. Since the prompt indicates no specific products are currently available, this section provides general advice for when they are.
Pro Tip: Always replace the drum brake hardware kit whenever you replace your brake shoes. The old springs lose their tension over time and reusing them can lead to noise and premature wear on your new shoes. A complete kit is inexpensive and ensures a safe, quiet, and long-lasting brake job.
When shopping, ensure the kit is specified for a 1977-1981 Pontiac LeMans with 9.5-inch rear drums, which was the standard size for most models. A complete kit should include all return springs, retainer springs, and pins for both rear wheels.

Frequently Asked Questions (FAQ)
Why can't I find a drum brake hardware kit for my 1979 Pontiac Tempest?
You cannot find parts because the Pontiac Tempest was not made in 1979. The car you own is likely a Pontiac LeMans. You need to search for parts for a 1979 Pontiac LeMans to find the correct components.
What was the difference between the Tempest and the LeMans?
In the 1960s, the LeMans was an upscale trim level of the Tempest. After 1970, Pontiac retired the Tempest name in the U.S. and promoted the LeMans to be its own model line, effectively replacing the Tempest.
Do I need to replace the hardware if it looks okay?
Yes. The springs lose their strength from heat and millions of cycles. Even if they are not visibly broken, they may not be strong enough to pull the brake shoes back correctly, leading to brake drag. For the low cost of a kit, it is essential preventative maintenance during any brake job.
Is replacing the drum brake hardware a difficult job?
It can be tricky for a beginner. The springs are under tension and require special tools (like brake spring pliers) for safe removal and installation. However, it is a feasible DIY job for someone with moderate mechanical experience. If you are not comfortable working on brakes, it is best to leave this job to a professional mechanic.
