How to Replace Drum Brake Shoes: Complete DIY Guide

Drum brake shoe replacement is an intermediate-level DIY project that typically takes two to four hours per axle, depending on your familiarity with brake systems and the condition of your vehicle's hardware. This guide provides general steps applicable to most domestic and import vehicles with rear drum brakes, but specific tools, torque specifications, procedures, and spring configurations vary significantly by make, model, and year. Before beginning any brake work, consult your vehicle's service manual to understand the exact layout of your brake assembly, the proper adjustment procedure, and all fastener torque values specific to your vehicle.

What You'll Need

Tools

• Socket set and wrenches (metric and standard, depending on vehicle)
• Wheel jack and a pair of jack stands rated for your vehicle's weight
• Tire iron or breaker bar for lug nut removal
• Drum brake spring removal tool or heavy-duty needle-nose pliers
• Brake drum removal tool (if drums are stuck) or a rubber mallet for gentle persuasion
• Wire brush or soft brass brush for cleaning
• Torque wrench calibrated to manufacturer specs
• Brake cleaner and lint-free rags or shop towels
• Flathead and Phillips screwdrivers for adjuster or fastener work
• HEPA-certified vacuum or damp cloth for dust collection
• Respirator or N95 mask rated for brake dust
• Work light or flashlight for visibility inside the drum assembly

Parts and Materials

• Drum brake shoe kit (typically includes shoes with friction material bonded to the metal backing)
• Return springs and hold-down springs (often included in brake shoe kits but verify before starting)
• Brake adjuster components (screw and pivot, if not included in the kit)
• High-temperature brake grease for pivot points and contact areas (use sparingly)
• New wheel cylinder if the existing one shows signs of leakage or damage
• Hardware replacement set if backing plate bolts are damaged or missing

Before You Begin

• Park your vehicle on a level, paved surface away from traffic, and engage the parking brake fully. Loosen the wheel lug nuts slightly (about one-quarter turn) while the vehicle is still resting on the ground—this makes removal much easier once the wheel is raised.

• Always use proper jack stands rated for your vehicle's weight; never rely solely on a hydraulic jack to support the vehicle while you work. Position the stands under the frame or suspension points designated in your owner's manual, and work on one wheel at a time to keep the vehicle's weight properly distributed.

• Brake dust from older brake shoes may contain asbestos or other harmful materials; wear an appropriate respirator (N95 or better) while handling the assembly. Clean the brake components using brake cleaner and a damp cloth, or a HEPA-certified vacuum—never use compressed air, which spreads dust into the air.

• Drum brakes are safety-critical components. If you have little or no experience working on brake systems, have a qualified mechanic perform this work or, at minimum, inspect your completed installation before driving the vehicle. Improper drum brake shoe installation, spring assembly, or adjustment can result in brake failure, uneven braking, or loss of stopping power—all of which pose serious safety hazards. Do not proceed if you are unsure about any step.

Step-by-Step: How to Replace Drum Brake Shoes

1. Prepare the vehicle and remove the wheel. With the lug nuts already loosened, position the jack under a frame reinforcement or suspension point (never under body panels) and raise the vehicle until the wheel clears the ground by several inches. Immediately place jack stands under the frame or axle housing on both sides of the wheel you are working on, then slowly lower the jack until the vehicle rests fully on the stands. Finish removing the lug nuts and carefully pull the wheel straight toward you to free it from the hub.
2. Remove the brake drum. The drum is typically held in place by the wheel studs and may also be bolted to the hub; remove any bolts first. If the drum slides off easily by hand, do so gently. If it is stuck, do not force it—instead, use a drum puller tool following the manufacturer's instructions, or tap gently around the drum's perimeter with a rubber mallet to break the friction. If the drum has been badly corroded or damaged, consult a mechanic rather than risking damage to the hub.
3. Inspect and clean the brake assembly. Once the drum is off, visually examine the backing plate (the stationary metal surface to which shoes attach), springs, adjusters, and wheel cylinder for cracks, heavy corrosion, or leakage. Spray the entire assembly with brake cleaner and wipe away dust and debris using a damp cloth; use your respirator during this process. If the backing plate is severely corroded, cracked, or if the wheel cylinder is leaking fluid, stop work and consult a qualified mechanic, as these conditions require professional repair or replacement.
4. Disconnect and remove the old brake shoes. Using a drum brake spring removal tool or heavy needle-nose pliers, carefully disconnect the upper and lower return springs by unhooking them from the shoe ends and the backing plate. Next, remove the hold-down springs and pins (these typically consist of a spring and retainer clip) by pressing in and twisting the retainer clip. Before pulling the shoes away from the backing plate, photograph or sketch the exact arrangement of all springs and the position of the adjusting screw—this reference image is invaluable during reassembly and prevents frustrating errors later.
5. Remove the hardware and adjust mechanism. Disconnect the adjusting screw assembly (also called the brake adjuster or star wheel) by unbolting it or sliding the shoes apart as needed to release it from the backing plate. If the wheel cylinder must be replaced, disconnect its brake line using a line wrench and remove the mounting bolts; if it is in good condition with no leaks, you may leave it in place. Remove any other springs, pins, or hardware and inspect them; reusable parts may be cleaned and reused, but replace anything that is bent, cracked, or shows signs of excessive wear or corrosion. Organize removed hardware in a small container to keep track of it.
6. Prepare and install new brake shoes. Remove any protective plastic coating or anti-rattle compound from the new shoes if present (check the kit instructions). Position each new shoe on the backing plate, ensuring the curved friction surface faces inward toward where the drum will sit. Attach the hold-down springs and pins to secure each shoe in place—the shoe should be able to move slightly but not fall away from the backing plate. Install the upper and lower return springs using your reference photo or service manual as a guide; the springs must be positioned exactly as they were on the original shoes to ensure proper brake action and release.
7. Reinstall the adjuster and wheel cylinder. Thread the adjusting screw assembly back into its position between the shoe ends, ensuring it is fully seated. If you removed the wheel cylinder, reinstall it now, torque the mounting bolts securely, and reconnect the brake line with a line wrench (hand-tight first, then use a wrench to tighten to avoid overtightening). Verify that the adjuster moves freely; if it is stiff or sticky, clean it lightly with brake cleaner or apply a tiny amount of high-temperature brake grease to the pivot point (do not over-grease, as excess lubricant attracts dust). Torque all fasteners to the specifications listed in your service manual.
8. Reassemble the drum and wheel. Carefully slide the brake drum straight back onto the hub, taking care not to pinch any wires, springs, or shoe edges. If the drum does not slide on smoothly, stop and check that all springs are positioned correctly and the shoes are not sticking out too far. Once the drum is fully seated, thread the mounting bolts by hand first to ensure they are properly aligned, then tighten them in a star pattern (opposite sides alternately) to ensure even pressure. Remount the wheel and hand-tighten all lug nuts.
9. Lower the vehicle and adjust the brakes. Carefully lower the vehicle by raising the jack slightly and removing the jack stands, then lowering the vehicle fully until the wheel sits flat on the ground. Remove the jack from under the vehicle. Using a calibrated torque wrench, torque all wheel lug nuts to the specification in your owner's manual—this is essential for safe wheel retention. Drum brakes require a final adjustment: refer to your service manual for your vehicle's exact procedure. Most vehicles require driving in reverse while lightly applying the brakes to allow the self-adjusting mechanism to set the shoes to the correct clearance, or you may need to manually adjust the star wheel adjuster until a slight drag is felt when rotating the wheel, then back off the adjuster slightly. This adjustment varies significantly by vehicle design, so do not skip this step and do not guess—consult your service manual.
10. Test the brakes and inspect your work. Sit in the driver's seat and pump the brake pedal several times until firm resistance is felt; the pedal should not sink to the floor. Test the brakes at low speeds in an empty parking lot before returning to normal driving. Listen for any unusual noises (grinding, squeaking, or clicking) and feel for vibration through the pedal or steering wheel. If the pedal feels soft, the brakes drag, or you hear unusual noises, stop driving immediately and consult a qualified mechanic before operating the vehicle further.

Tips for a Successful Drum Brake Shoe Replacement

• Take clear photographs or make a detailed sketch of the brake assembly before you remove anything. This reference is your best insurance against spring mix-ups and reassembly errors—drum brake spring layouts vary by vehicle, and misplaced springs are a common cause of poor braking or brake drag. Spend a few minutes documenting the setup now to save hours of frustration later.

• Avoid over-greasing the adjuster mechanism or backing plate contact areas. High-temperature brake grease is necessary at pivot points and where the shoe ends contact the adjuster, but excess grease attracts brake dust and can interfere with proper brake operation. Apply only a small dab at each contact point and wipe away any surplus with a clean cloth.

• Always replace all four brake shoes (both shoes on the entire rear axle) at the same time, even if only one wheel shows significant wear. Uneven replacement leads to unbalanced braking, pulling to one side, and premature wear of the newly installed shoes. Treat the rear axle as a pair and replace the complete set.

• If you are uncertain about the final brake adjustment procedure or if the brake pedal does not feel firm and responsive after your work is complete, have a certified mechanic verify the adjustment and test the brakes. This small investment in professional verification ensures that your safety-critical brake system is functioning correctly and gives you confidence in your work.

When to Call a Professional

Stop work and contact a qualified mechanic if you encounter a leaking or damaged wheel cylinder, a cracked or severely corroded backing plate, damaged hardware that cannot be sourced as replacements, or any other component that appears unsafe or requires special tools to remove. Additionally, if you have never serviced a brake system before, you may prefer to have a professional perform the complete replacement or, at minimum, inspect your finished work and verify that the brake adjustment is correct before you drive the vehicle. Drum brakes are more involved than many people expect, and the adjustment procedure in particular varies widely between vehicles. A certified mechanic can ensure that all fasteners are torqued to specification, that the brake shoes are properly adjusted with the correct clearance, and that the system functions safely. Your safety and that of others on the road depends on correct brake function—if there is any doubt, seek professional help.
