Replacing drum brakes involves several steps, and it’s important to work carefully because brakes are critical for safety. Here’s a detailed step-by-step guide:
🛠 Tools & Materials Needed
- Jack and jack stands
- Lug wrench
- Brake spring tool (or pliers)
- Screwdrivers (flathead & Phillips)
- Hammer or rubber mallet
- Socket set or wrench
- Brake cleaner
- New brake shoes
- Anti-seize or brake grease
Step-by-Step Drum Brake Replacement:
1. Prepare the Vehicle
- Park on a level surface and engage the parking brake.
- Loosen the wheel lug nuts slightly before jacking up the car.
- Jack up the car and place it on jack stands.
- Remove the wheel to access the drum.
2. Remove the Drum
- Some drums just pull off; others may have retaining screws.
- If the drum is stuck, tap gently around the edge with a rubber mallet or use a screwdriver to back off adjuster inside.
- Inspect the drum for scoring or damage — you may need to resurface or replace the drum.
3. Remove Old Brake Shoes
- Take a picture of the current setup — note how springs and shoes are arranged.
- Remove the return springs using a spring tool or pliers.
- Remove the hold-down springs/pins.
- Detach the wheel cylinder (if needed) and disconnect the brake shoes from the adjuster.
- Carefully remove old brake shoes.
4. Clean & Inspect
- Spray brake cleaner on the backing plate and other components.
- Inspect the wheel cylinder, springs, and adjuster — replace any worn parts.
- Apply a small amount of brake grease to contact points on the backing plate.
5. Install New Brake Shoes
- Position the new shoes on the backing plate.
- Attach the hold-down springs/pins to secure them.
- Reconnect the adjuster and wheel cylinder if removed.
- Hook the return springs carefully — they can snap, so use caution.
6. Reinstall the Drum
- Slide the drum back onto the hub.
- If it’s tight, slightly adjust the brake adjuster to fit.
- Ensure the drum spins with slight resistance (shoes lightly touching).
7. Reassemble Wheels
- Reinstall the wheel and tighten lug nuts snugly.
- Lower the car and fully tighten the lug nuts in a star pattern.
8. Final Steps
- Pump the brake pedal a few times to seat the shoes properly.
- Check parking brake operation.
- Take a slow test drive in a safe area to ensure braking is smooth and effective.
⚠ Safety Tips
- Never work under a car supported only by a jack — always use jack stands.
- Work carefully with brake springs — they are under tension.
- Avoid breathing brake dust — use a mask and brake cleaner.
