Replacing the Drum Brake Hardware on Your 1992-1998 GMC Jimmy
Keep your Jimmy's rear brakes working properly by knowing when and how to replace the essential hardware.
- Always replace the drum brake hardware kit when you replace the brake shoes to ensure proper function and even wear.
- Brake noises, a weak parking brake, or a soft pedal are key signs that your hardware may be failing.
- Aftermarket brands like Raybestos, Centric, and Dorman offer quality replacement kits that are a cost-effective choice for this vehicle.
- Be aware of the 1991-1996 ABS recall that affected these trucks, as it relates to overall braking safety.
Symptoms of a Failing Drum Brake Hardware Kit
Worn-out hardware can cause a range of braking problems. Because these parts are inside the brake drum, you can't see them without taking the wheel and drum off. Listen and feel for these signs:
- Brake Noise: A common sign of failing hardware is unusual noises from the rear of your truck when you brake. You might hear scraping, grinding, or clicking sounds. This can happen when a weak or broken spring allows a brake shoe to drag or sit crooked.
- Spongy or Soft Brake Pedal: If the springs aren't retracting the brake shoes properly, you might notice your brake pedal feels soft or goes down further than usual.
- Poor Parking Brake Performance: The drum brake hardware is essential for a properly functioning parking brake. If your Jimmy rolls on a hill when the parking brake is set, or the handle pulls up too easily, the hardware may be worn out.
- Uneven Brake Shoe Wear: When you replace your brake shoes, if you notice one shoe is worn down much more than the other, it's a sure sign the hardware wasn't holding them correctly. This is why you should always replace the hardware with the shoes.
Known Vehicle Issue: ABS Recall
While not specific to the hardware kit itself, be aware that GM issued a major recall for the anti-lock brake system on 1991-1996 4-wheel drive GMC Jimmys. A faulty switch could make the ABS system think the truck was in 4-wheel drive when it was in 2-wheel drive, increasing stopping distances. While this is an old recall, it's a critical piece of your truck's braking history. Ensure any related issues have been addressed.
Choosing the Right Aftermarket Hardware Kit
For a vehicle like the '92-'98 Jimmy, aftermarket parts are readily available and often provide excellent value. The original hardware was made by GM's parts division, ACDelco. Aftermarket brands often meet or exceed these original standards.
Pro Tip: Always replace your drum brake hardware kit whenever you replace your brake shoes. The cost is low, and it ensures the new shoes work correctly and last as long as possible. Most kits include all the springs and clips for both rear wheels.

Frequently Asked Questions (FAQ)
Do I need special tools to replace the hardware kit?
While you can do the job with standard pliers and screwdrivers, special drum brake spring tools make it much easier and safer. The springs are under high tension and can be difficult to install and remove without the right leverage.
Do these kits work for both 2WD and 4WD models?
Generally, yes. The rear drum brake setup is the same for both 2WD and 4WD models of the 1992-1998 GMC Jimmy. However, always confirm the fitment for your specific vehicle before purchasing.
Should I replace anything else at the same time?
Yes. The hardware kit should always be replaced with the brake shoes and drums. This is also the perfect time to inspect the wheel cylinders for any brake fluid leaks. If you see any wetness, replace the wheel cylinder as well.
What is the difference between ACDelco Gold and OEM parts?
ACDelco offers different tiers. Their OEM line is what was originally installed on the vehicle. The "Gold" or "Professional" line is their high-quality aftermarket offering, which may differ slightly from the original but is still considered a premium part. For this application, either is a good choice.
