How to Replace Drum Brake Shoe Return Springs

Drum brake shoe return springs wear out gradually and eventually lose their tension, resulting in slower brake response, longer stopping distances, and increased wear on your brake shoes. This is a moderate-difficulty repair that typically takes 1–2 hours per wheel and is manageable for owners with basic mechanical experience and access to hand tools. These instructions provide general guidance; specific tools, torque specifications, removal sequences, and procedures vary significantly by vehicle make and model. You must consult your vehicle's service manual for accurate, model-specific information before starting work.

Tools

• Socket set and ratchet wrench
• Drum brake spring removal tool or equivalent leverage tool
• Needle-nose pliers and standard pliers
• Flathead and Phillips screwdrivers
• Floor jack and jack stands
• Wheel chocks
• Brake drum removal tool (if needed for stubborn drums)
• Safety glasses and work gloves

Parts & Materials

• Drum brake shoe return spring kit (includes springs, clips, and hardware)
• Brake cleaner (aerosol or spray bottle)
• High-temperature brake grease or lubricant
• Shop towels or lint-free rags
• Replacement brake shoes (if worn beyond safe limits)

• Work on level ground and use jack stands: Always position the vehicle on a flat, level surface. Use a floor jack to lift the vehicle, but immediately secure it with properly rated jack stands under the frame. Never rely on a jack alone—jack failure can cause serious injury or death.
• Disconnect the negative battery terminal: This prevents any accidental electrical issues while you work on the brake system and reduces the risk of deploying airbags if your vehicle has an integrated stability control system.
• Remove the wheel and brake drum: After safely raising the vehicle and securing it with jack stands, remove the wheel and then the brake drum to fully expose the brake assembly and spring components.
• Inspect the entire brake system: Before proceeding, examine the drums for cracks, severe scoring, or uneven wear. Check the backing plate for corrosion, cracks, or damage. If the drums are severely worn or the backing plate is compromised, professional inspection and service are strongly recommended.
• Important safety note: Drum brakes are a safety-critical component. If you are not experienced with brake system repairs, it is highly advisable to have a qualified mechanic perform or inspect this work before and after completion to ensure proper function and your safety on the road.

1. Remove the brake drum by unbolting it from the wheel hub. If the drum is stuck, use a brake drum removal tool or apply penetrating oil and tap gently with a rubber mallet. Set the drum aside on a clean surface where you can inspect its condition.
2. Document the spring configuration before touching anything. Take clear photos or video from multiple angles showing how the old springs are routed, clipped, and positioned on both the brake shoes and backing plate. This visual reference is invaluable for reassembly and ensures you don't misroute the new springs.
3. Use the spring removal tool to carefully detach the old return springs from the brake shoe and backing plate connection points. Work slowly and deliberately to avoid damaging the shoes, springs, or backing plate. Older springs may be stiff or brittle—take extra care not to let them snap suddenly.
4. Remove the spring retaining clips or hardware that hold the springs in place. Note the size, type, and orientation of each clip so you install them correctly with the new springs. Keep all hardware organized and within reach.
5. Clean the backing plate and shoe contact areas thoroughly using brake cleaner and a clean rag. Remove all brake dust, rust, and debris. Pay special attention to the pivot points and spring anchor locations on the backing plate, as these must be clean for proper spring seating and function. Specific torque specifications, reassembly sequence, and spring preload settings vary significantly by vehicle make and model—you must verify these critical values in your service manual before final assembly.
6. Apply high-temperature brake grease sparingly to the pivot points, shoe contact surfaces on the backing plate, and any moving joints where the springs connect. Use only a tiny amount—excess grease can migrate onto friction surfaces and reduce braking performance. Wipe away any excess with a clean rag.
7. Install the new return springs in the exact same configuration as shown in your photos and your service manual. Start by securing the springs to the backing plate anchor points with their retaining clips, then carefully attach them to the brake shoes. Ensure each spring is fully seated, not twisted, and under proper tension as specified in your manual.
8. Verify all springs are properly positioned by checking that they are parallel to the backing plate, not crossed over one another, and that they pull the brake shoes inward evenly when you gently apply pressure. Misaligned springs reduce braking power and accelerate wear.
9. Reinstall the brake drum by sliding it carefully back onto the wheel hub and securing it with the original bolts. Tighten bolts in a star or crossing pattern to ensure even seating, then torque them to your vehicle's specification as outlined in the service manual.
10. Reinstall the wheel and lower the vehicle to the ground using the jack. Tighten the wheel lugs in a similar star pattern and to the correct torque specification for your vehicle.

• Document your work with photos before disassembly: Take clear pictures or short video clips showing the original spring routing, clip positions, and how springs attach to both the shoes and backing plate. This visual reference prevents mistakes during reassembly and can be reviewed if you get stuck partway through the job.
• Always replace return springs in pairs: Replace the springs on both wheels of the same axle (front or rear) during the same service interval. Using new springs on one side and old springs on the other creates uneven braking pressure, which can cause the vehicle to pull to one side and accelerates wear on the newer springs.
• Never reuse old springs: Return springs lose their mechanical tension over time and will fail prematurely if reinstalled. Always use new springs from a complete spring kit to ensure consistent tension and predictable braking performance across the life of the brake shoes.
• Check spring alignment after installation: Ensure springs are fully seated, not twisted or crossed, and positioned parallel to the backing plate. Misalignment reduces braking force, increases stopping distance, and can cause uneven shoe wear or brake noise.

If you encounter severe corrosion or rust on the backing plate, difficulty removing old springs without visible damage to brake components, cracks in the drums, or if you simply lack confidence in your ability to properly reassemble the system, stop and contact a certified mechanic. Brakes are a safety-critical system—any uncertainty about proper installation should be resolved by a qualified professional before driving your vehicle. It's far better to invest in professional service than to risk brake failure on the road. A mechanic can also inspect the overall condition of your drum brake system and advise whether shoes, wheel cylinders, or other components need attention while the drums are already off.
