Symptoms of a Failing Drum Brake Hardware Kit
Worn-out hardware can cause a variety of brake problems. Here are the most common signs:
🎬 Watch this video to help diagnose worn-out brake drum symptoms.- Scraping or Squeaking Noises: A common symptom is noise that occurs when you are not braking. This can be caused by weak return springs that fail to pull the brake shoes fully away from the drum, causing them to drag lightly.
- Parking Brake Feels Loose: If your parking brake handle pulls up higher than it used to or doesn't hold the car securely, it can be a sign that the self-adjusting components in the hardware kit have failed or the shoes are worn.
- Brakes Locking Up or Grabbing: Broken or weak springs can allow the brake shoes to shift, leading to sudden and unexpected brake engagement.
- Spongy Brake Pedal: If the self-adjuster mechanism seizes, it can't keep the shoes close to the drum as they wear. This creates excessive space, which can make the brake pedal feel soft or travel further to the floor before the brakes engage.
No Specific Recalls, But Known Issues Exist
There have been no safety recalls or Technical Service Bulletins (TSBs) issued by GM specifically for the drum brake hardware on the 2007-2010 Pontiac G5. However, the self-adjuster mechanism is a known weak point that can seize with rust and brake dust, leading to poor brake performance. During any brake job, it's critical to clean and lubricate the adjuster or replace it if it's part of your new hardware kit.

Frequently Asked Questions (FAQ)
Do I have to replace the hardware kit with my brake shoes?
Yes, it is highly recommended. The old springs have been subjected to the same heat and wear as your old shoes. Reusing them can cause noise, dragging, and premature wear on your new brake shoes and drums. For the low cost of a kit, it is not worth the risk.
Does one hardware kit cover both rear wheels?
Yes, a standard drum brake hardware kit contains all the necessary parts to service both the left and right rear brakes.
What is a self-adjuster and why is it important?
The self-adjuster is a small mechanism that automatically turns a threaded wheel to move the brake shoes closer to the drum as the shoe material wears down. This keeps the brake pedal feel consistent. These can seize from rust, and a new hardware kit often helps restore this function.
Is replacing the drum brake hardware a good DIY job?
For a mechanic with some experience, yes. However, drum brakes can be tricky. The springs are under tension and require special tools (like brake spring pliers) to handle safely. Also, the brake drum itself can be severely rusted to the hub, requiring force to remove. If you are not comfortable, it's best to leave this job to a professional.
