- Allow Brakes to Cool: If you’ve been driving, the brake components will be hot. Let them cool down completely before starting work.
- Gather All Necessary Tools: Besides brake spring pliers, you’ll likely need a pry bar, brake cleaner, new hardware (if replacing), and a torque wrench.
Removing Brake Springs with Pliers
The process of removing brake springs typically involves a pulling action.
For Return Springs (Most Common)
These springs connect the bottom of the brake shoes to an anchor pin on the backing plate.
- Locate the Spring: Identify the brake return spring. It’s usually a coiled spring attached to the lower portion of both brake shoes and an anchor pin protruding from the backing plate.
- Grip the Spring: Position the jaws of your brake spring pliers onto the loop of the return spring. Ensure a firm grip.
- Pull and Rotate (If Necessary):
- Gently pull the spring away from its anchor point. You might need to apply a steady, controlled pull.
- Some springs may require a slight rotation or rocking motion to disengage from the anchor pin or the brake shoe.
- The long handles of the pliers provide the leverage needed.
- Unhook the Spring: Once the spring is sufficiently stretched, maneuver the pliers to unhook the spring from its anchor pin or the brake shoe.
- Hold or Secure the Spring: Once removed, keep the spring contained or placed safely aside so it doesn’t spring loose unexpectedly.
For Brake Shoe Hold-Down Springs
These springs often hold the brake shoe against the backing plate, usually with a small cup or retainer.
- Identify the Spring Mechanism: These springs often have a retainer cup and a spring that pushes against it.
- Compress and Lift:
- Use the angled jaws of your brake spring pliers to grip the end of the spring or the retainer cup.
- Apply downward pressure on the spring to compress it.
- While compressed, rotate the retainer cup slightly (often with the pliers or another tool) to disengage it from the backing plate.
- Carefully lift the entire assembly away.
- Release Tension Safely: Once the retainer is off the backing plate, slowly release the tension on the spring to avoid it snapping.
Installing Brake Springs with Pliers
Installing springs is often more challenging than removing them, as you’re working against the spring’s natural tension.
Installing Return Springs
- Position the Brake Shoes: Ensure the brake shoes are correctly positioned on the wheel cylinder pistons and the anchor pin.
- Hook One End: Attach one end of the return spring to either the brake shoe or the anchor pin, depending on which is easier to access first. A slight hook with the pliers might be enough.
- Grip the Other End: Use your brake spring pliers to grip the other end of the spring.
- Stretch and Attach:
- Carefully stretch the spring towards its intended anchor point.
- You will need to apply significant leverage with the pliers to stretch the spring far enough to hook it onto the anchor pin or the brake shoe.
- Watch your fingers and ensure a firm grip on both the spring and the pliers.
- Gently guide the spring’s loop onto its post.
Installing Brake Shoe Hold-Down Springs
- Position the Shoe: Place the brake shoe against the backing plate.
- Place the Retainer and Spring: Position the retainer cup and spring over the backing plate stud.
- Compress and Engage:
- Use your brake spring pliers to grip the spring or the retainer cup.
- Compress the spring by pushing downwards with the pliers.
- While compressed, rotate the retainer cup until it locks into place on the backing plate stud. This often involves twisting the pliers or the retainer itself.
- Once locked, slowly release the pressure from the pliers.
Tips for Using Brake Spring Pliers Effectively
- Choose the Right Pliers: Ensure you are using the correct type of brake spring pliers for the specific spring you are working with. The wrong tool can make the job impossible or dangerous.
- Work in Good Lighting: Adequate lighting will help you see what you’re doing, preventing mistakes and ensuring you grip the spring correctly.
- Cleanliness is Key: Keep the brake components clean. Dirt and debris can interfere with spring installation and overall brake function.
- Practice on a Bench: If you’re new to this, consider practicing on old brake components you have lying around. This allows you to get a feel for the tools and techniques without the pressure of working on a vehicle.
- Don’t Force It: If a spring is extremely difficult to install or remove, double-check that you have the correct tool and that the brake shoes are properly aligned. Forcing can damage parts.
Common Challenges and Solutions with Brake Spring Pliers
Even with the right tools, brake spring work can present challenges. Here are some common issues and how to overcome them.
Stubborn Springs
Some return springs are incredibly strong, designed for durability and effective brake shoe return.
- Solution: Ensure you are using pliers with good leverage. A drum brake spring compressor might be necessary for very stiff springs. Sometimes, a slight rocking motion while pulling can help initiate movement. Lubricating the anchor pin slightly with brake lubricant can also ease installation, but avoid getting lubricant on the brake shoe friction material.
Difficulty Gripping the Spring Loop
The loops on brake springs can sometimes be worn or difficult to get a secure grip on.
- Solution: Try different angles with your brake spring pliers. If the loop is damaged, the spring might need replacement anyway. Ensure the jaws of your pliers are clean and not worn down.
Springs Snapping Off
This is a common safety concern. A spring that releases unexpectedly can cause injury.
- Solution: Maintain a firm, controlled grip at all times. Never place your hands or fingers directly in the path of a spring that is under tension. Release tension slowly and deliberately.
Alignment Issues During Installation
Getting the spring to align perfectly with its anchor points can be tricky.
- Solution: A helper can be invaluable here to hold the brake shoe in place while you stretch the spring. Sometimes, slightly adjusting the position of the brake shoe itself can help the spring align better. Use a small pry bar or screwdriver for delicate nudging if necessary, but be careful not to damage components.
Using the Wrong Tool
Attempting to use regular pliers or vice grips for brake springs is a common mistake.
- Solution: Invest in proper brake spring pliers. They are relatively inexpensive and are designed for the task, making the job significantly easier and safer. The specialized shape of the jaws is crucial for a secure grip.
Maintenance and Care of Your Brake Spring Pliers
To ensure your brake spring pliers remain effective and safe to use, proper maintenance is essential.
- Clean After Use: Always clean off brake dust, grease, and dirt after each use. A clean rag and some brake cleaner will suffice.
- Inspect for Damage: Regularly check the jaws for wear, damage, or bending. Worn jaws will reduce grip and increase the risk of slippage. Inspect the handles for cracks or damage to the grips.
- Lubricate Pivot Points: If your pliers have a pivot point, a tiny amount of lubricant can help them operate smoothly.
- Store Properly: Keep them in a toolbox or a dedicated spot where they won’t be damaged or lost.
Frequently Asked Questions (FAQ)
