Brake rewind tools are an essential component in the maintenance and repair of braking systems in vehicles. They play a crucial role in ensuring the safe operation of vehicles by enabling mechanics to rewind brake shoes and adjust the brake drum to the correct clearance. In this article, we will delve into the world of brake rewind tools and explore how to use them effectively. From understanding the different types of brake rewind tools to learning the step-by-step process of rewinding brake shoes, we will cover everything you need to know to become proficient in using a brake rewind tool.
The importance of brake rewind tools cannot be overstated. A brake rewind tool is a specialized device designed to rewind brake shoes back to their original position, ensuring proper brake function and preventing premature wear on brake components. Without a brake rewind tool, mechanics may be forced to resort to more labor-intensive and potentially hazardous methods, such as using a hammer and chisel to remove worn-out brake shoes. This not only increases the risk of injury but also leads to a higher likelihood of brake failure, which can have disastrous consequences on the road.
Additionally, brake rewind tools are an essential tool for any mechanic who works on vehicles with drum brakes. Drum brakes are a common type of brake system found in many vehicles, and they require regular maintenance to ensure optimal performance. A brake rewind tool is a must-have for any mechanic who wants to perform brake repairs efficiently and effectively.

Types of Brake Rewind Tools
There are several types of brake rewind tools available in the market, each designed to cater to specific brake systems and applications. Some of the most common types of brake rewind tools include:
- Manual Brake Rewind Tools: These are the most basic type of brake rewind tool and are typically used for small-scale brake repairs. Manual brake rewind tools are usually handheld devices that require manual effort to rewind brake shoes.
- Pneumatic Brake Rewind Tools: These are more advanced types of brake rewind tools that use compressed air to rewind brake shoes. Pneumatic brake rewind tools are faster and more efficient than manual tools but require a power source to operate.
- Hydraulic Brake Rewind Tools: These are the most advanced type of brake rewind tool and are typically used in heavy-duty brake repairs. Hydraulic brake rewind tools use hydraulic pressure to rewind brake shoes and are capable of handling large brake drums.
When choosing a brake rewind tool, it is essential to consider the type of brake system being repaired, the size of the brake drum, and the level of force required to rewind the brake shoes. It is also crucial to select a tool that is compatible with the vehicle’s make and model.
Step-by-Step Guide to Using a Brake Rewind Tool
Using a brake rewind tool is a relatively straightforward process that requires attention to detail and a basic understanding of brake systems. Here is a step-by-step guide to using a brake rewind tool:
Step 1: Remove the Brake Drum
The first step in using a brake rewind tool is to remove the brake drum. This involves loosening the brake drum retaining screws and sliding the drum off the wheel hub. Be careful not to damage the brake drum or the wheel hub during this process.

Step 2: Inspect the Brake Shoes
Once the brake drum is removed, inspect the brake shoes for wear and damage. Look for signs of excessive wear, such as uneven wear patterns or worn-out linings. If the brake shoes are excessively worn, they may need to be replaced.
Measuring the Brake Shoe Wear
To measure the brake shoe wear, use a brake shoe wear gauge to determine the thickness of the brake shoe lining. Compare the measurement to the manufacturer’s specifications to determine if the brake shoes need to be replaced.
Step 3: Rewind the Brake Shoes
Once the brake shoes have been inspected, use the brake rewind tool to rewind the brake shoes back to their original position. This involves inserting the tool into the brake drum and turning the handle to rewind the brake shoes.
Using the Brake Rewind Tool
To use the brake rewind tool, insert the tool into the brake drum and turn the handle clockwise to rewind the brake shoes. Be careful not to over-tighten the brake shoes, as this can cause damage to the brake drum or the wheel hub.
Step 4: Reinstall the Brake Drum
Once the brake shoes have been rewound, reinstall the brake drum by sliding it back onto the wheel hub and tightening the brake drum retaining screws. Be careful not to overtighten the screws, as this can damage the brake drum or the wheel hub.
Tips and Precautions
Using a brake rewind tool requires attention to detail and a basic understanding of brake systems. Here are some tips and precautions to keep in mind when using a brake rewind tool:
