Proper brake maintenance is essential for ensuring the safety of your vehicle and its occupants. One crucial aspect of brake maintenance is rewinding the rear brake caliper, a process that can be daunting for many car owners. However, neglecting to rewind the rear brake caliper can lead to uneven brake wear, reduced braking performance, and even accidents. In this guide, we will walk you through the step-by-step process of rewinding the rear brake caliper, providing you with the knowledge and confidence to tackle this critical task.
What You’ll Need
To rewind the rear brake caliper, you’ll need a few tools and some basic knowledge of brake systems. Don’t worry if you’re not a seasoned mechanic – we’ll break down the process into manageable steps, and provide tips and tricks to help you along the way.
Overview of the Rewind Process
The rewind process involves compressing the brake caliper piston, removing the old brake pads, and reinstalling new ones. Sounds simple, but it requires attention to detail and a bit of patience. In the following sections, we’ll delve deeper into each step, providing detailed instructions and helpful tips to ensure a successful rewind.
Rewinding a Rear Brake Caliper: A Step-by-Step Guide
Rewinding a rear brake caliper is a crucial process that requires attention to detail and a thorough understanding of the brake system. In this article, we will walk you through the steps involved in rewinding a rear brake caliper, highlighting the importance of each step and providing tips and precautions to ensure a successful outcome.
Why Rewind a Rear Brake Caliper?
A rear brake caliper needs to be rewound when the brake pads wear out, causing the caliper to move outward and away from the rotor. This can lead to uneven brake wear, reduced braking performance, and increased risk of brake failure. Rewinding the caliper brings it back to its original position, ensuring proper brake function and safety.
Tools and Materials Needed
To rewind a rear brake caliper, you will need the following tools and materials:
- Rear brake caliper rewind tool (specific to your vehicle make and model)
- Brake lubricant (silicone-based or ceramic-based)
- Brake cleaner
- Rags
- New brake pads (if replacing)
- Wheel chocks (if working on a vehicle with a lift)
Preparation and Safety Precautions
Before starting the rewinding process, make sure to:
- Consult your vehicle’s repair manual for specific instructions and precautions.
- Wear protective gear, including gloves, safety glasses, and a face mask.
- Jack up the vehicle and support it with jack stands, ensuring the rear wheels are off the ground.
- Remove the wheel and any trim or covers to access the brake caliper.
- Disconnect the brake hose from the caliper, taking note of the brake fluid level.
- Use wheel chocks to prevent the vehicle from rolling, if working on a lift.

Step 1: Remove the Old Brake Pads
Use a wrench or pliers to remove the old brake pads from the caliper. Take note of the pad wear sensors, if equipped, and disconnect them from the pads.
Step 2: Clean the Caliper and Brake Rotor
Use a brake cleaner to remove any dirt, grime, or brake dust from the caliper and brake rotor. This ensures a clean surface for the new brake pads and prevents contamination.
Step 3: Apply Brake Lubricant
Apply a thin layer of brake lubricant to the back of the new brake pads and the caliper’s piston. This reduces friction and noise, ensuring smooth brake operation.
Step 4: Install the New Brake Pads
Install the new brake pads, making sure they are properly seated and the wear sensors are reconnected, if equipped.
Step 5: Rewind the Caliper
Use the rear brake caliper rewind tool to slowly turn the caliper’s piston clockwise, rewinding it back to its original position. Take note of the piston’s movement and stop when it reaches the desired position.
Step 6: Reconnect the Brake Hose
Reconnect the brake hose to the caliper, ensuring it is securely attached and the brake fluid level is at the recommended level.
Step 7: Bleed the Brake System
Bleed the brake system to remove any air that may have entered during the rewinding process. Use a brake bleeding kit and follow the manufacturer’s instructions. (See Also: Does Brake Fluid Ruin Car Paint)
Tips and Precautions
When rewinding a rear brake caliper, keep the following tips and precautions in mind:
- Use the correct rewind tool to avoid damaging the caliper or piston.
- Apply gentle and consistent pressure when rewinding the caliper to avoid damaging the piston or brake hose.
- Use a torque wrench to ensure the brake hose is properly tightened.
- Avoid mixing brake lubricants, as this can lead to brake failure.
- Test the brakes after rewinding to ensure proper function and performance.
Common Mistakes to Avoid
When rewinding a rear brake caliper, common mistakes to avoid include:
- Failing to clean the caliper and brake rotor, leading to contamination and brake failure.
- Not applying brake lubricant, causing increased friction and noise.
- Rewinding the caliper too quickly or with excessive force, damaging the piston or brake hose.
- Failing to bleed the brake system, leading to air in the lines and brake failure.
Conclusion
Rewinding a rear brake caliper is a critical process that requires attention to detail and a thorough understanding of the brake system. By following the steps outlined in this article, using the correct tools and materials, and taking necessary safety precautions, you can ensure a successful outcome and maintain your vehicle’s braking performance.
