How to Change Drum Brakes A Step-by-Step Guide

Changing drum brakes can be a daunting task for some, especially for those new to car maintenance. However, with the right tools and a bit of guidance, you can efficiently change your vehicle's drum brakes and ensure your car’s braking system functions effectively. This article will walk you through the process of changing drum brakes, making it easier to tackle this task confidently.

Tools and Materials Needed

Before you begin, gather all the necessary tools and materials - Jack and jack stands - Lug wrench - Brake cleaner - Screwdrivers (flathead and Phillips) - Pliers - Drum brake spring tools (if available) - New brake shoes - New drum (if necessary) - Replacement hardware (springs, clips, etc.) - Torque wrench (optional)

Safety First

Before working on your vehicle, ensure safety is your top priority. Park your car on a flat surface and engage the parking brake. Wearing safety goggles and gloves is also advisable to protect yourself from debris and sharp edges.

Step 1 Remove the Wheel

Using a lug wrench, loosen the lug nuts on the wheel where you will be changing the drum brakes. Once loosened, jack up the car and secure it with jack stands. After ensuring the vehicle is stable, completely remove the lug nuts and take off the wheel.

Step 2 Inspect the Drum

With the wheel removed, inspect the brake drum for any signs of wear or damage. If the drum appears grooved or excessively worn, it’s a good idea to replace it. Remove the drum by pulling it away from the hub. Sometimes, it may be stuck due to rust or debris; gently tap the drum with a hammer if necessary.

Step 3 Remove the Brake Shoes

Once the drum is off, you'll see the brake shoes. First, take a photo or make notes of how everything is assembled. This will be helpful for reassembly. Start by removing the springs using pliers or special brake spring tools. Remove the hold-down springs and pins that secure the brake shoes to the backing plate. Once released, carefully take off the brake shoes.

Before installing the new brake shoes, compare them to the old ones to ensure they are the correct size. Clean the backing plate and the inside of the drum with brake cleaner to remove dust and debris. This will ensure better performance for the new brake shoes.

Step 5 Install New Brake Shoes

Start by installing the new brake shoes into place, securing them with the hold-down springs and pins. Make sure that the shoes are mounted correctly according to the configuration you noted earlier. Reattach the return springs, ensuring they are tensioned properly to allow the shoes to retract after braking.

Step 6 Reattach the Brake Drum

Once the new brake shoes are securely in place, slide the brake drum back onto the wheel hub. It should fit snugly but still spin freely. If resistance is felt, check that the shoes are not rubbing against the drum.

Step 7 Reinstall the Wheel

With the brake drum in place, it’s time to put the wheel back on. Align it with the hub and hand-tighten the lug nuts. Lower the vehicle back to the ground and use the lug wrench to tighten the lug nuts fully in a crisscross pattern to ensure even pressure.

Step 8 Test the Brakes

Before taking your vehicle out on the road, press the brake pedal a few times to seat the brake shoes against the drum. This action is crucial as it helps to set the shoes in the right position. Once this is done, take the car for a short test drive in a safe area to ensure the brakes are functioning properly.

Conclusion

Changing drum brakes can save you both time and money, enabling you to maintain your vehicle more effectively. By following the steps outlined in this guide, you can handle the task with confidence. Always consult your vehicle’s manual for specific instructions, and if you ever feel uncertain, don’t hesitate to seek help from a professional mechanic. With practice, changing drum brakes can become a routine part of your car maintenance skills. Happy wrenching!
