Hey there, fellow automotive enthusiasts! As a supplier of rear drum brake shoes, I get a ton of questions about maintenance and repair. One of the most common queries I receive is how to replace the return spring in rear drum brake shoes. Today, I'm gonna walk you through the whole process step by step.
First off, let's talk about why this return spring is so important. The return spring in rear drum brake shoes plays a crucial role in getting the brake shoes back to their original position after you release the brake pedal. Without it, the brake shoes would stay in contact with the drum, causing unnecessary wear and tear, and even overheating. So, keeping this spring in good shape is essential for the proper functioning of your brakes.
Before we start, make sure you've got all the tools you need. You'll need a brake spring tool, a pair of pliers, a socket set, and a flat - head screwdriver. Safety first, so don't forget to wear gloves and safety glasses.
Step 1: Prepare Your Vehicle
Park your vehicle on a flat, level surface and engage the parking brake. Then, loosen the lug nuts on the wheel with the rear drum brake you're working on. Don't remove them completely just yet. Jack up the vehicle and support it with jack stands. Now you can remove the lug nuts and take off the wheel.
Step 2: Remove the Drum
Once the wheel is off, you'll see the brake drum. There are usually a couple of holes on the back of the drum. Use a flat - head screwdriver to turn the star wheel adjuster through these holes. This will retract the brake shoes, making it easier to remove the drum. If the drum is stuck, you can gently tap it with a rubber mallet.
Step 3: Locate the Return Spring
With the drum removed, you'll have a clear view of the brake assembly. The return spring is the one that connects the top (or sometimes the bottom) of the two brake shoes. It's usually a coiled spring that's under tension.
Step 4: Release the Spring Tension
This is where the brake spring tool comes in handy. Place the tool on the return spring and carefully compress it to release the tension. If you don't have a brake spring tool, you can try using a pair of pliers, but be extra careful as the spring can snap back and cause injury.
Step 5: Remove the Return Spring
Once the tension is released, you can use the pliers to carefully remove the return spring from its hooks on the brake shoes. Keep the spring in a safe place so you don't lose it.
Step 6: Inspect the Brake Shoes and Other Components
While you've got the brake assembly open, it's a good idea to take a look at the brake shoes. Check for signs of wear, such as uneven lining or excessive thinning. Also, inspect the brake hardware, like the hold - down springs and the adjuster mechanism. If any of these parts are worn out, it's a good time to replace them.
Step 7: Install the New Return Spring
Take your new return spring and place it on the hooks of the brake shoes. Use the brake spring tool to compress the spring and hook it into place. Make sure it's properly seated and there's no slack.
Step 8: Reassemble the Brake Drum
Before putting the drum back on, use a clean cloth to wipe away any dirt or debris from the drum and the brake shoes. Then, carefully place the drum over the brake shoes. Turn the star wheel adjuster again to expand the brake shoes until they just touch the drum.
Step 9: Reinstall the Wheel
Put the wheel back on and hand - tighten the lug nuts. Lower the vehicle off the jack stands and then use a torque wrench to tighten the lug nuts to the manufacturer's specifications.
Step 10: Test Your Brakes
Once everything is back together, start your vehicle and test the brakes at low speed in a safe area. Make sure the brakes feel normal and there are no strange noises or vibrations.
