A quick overview: Changing brakes on a Craftsman lawn mower involves removing the wheel, accessing the brake assembly, identifying and replacing worn-out components, and reassembling the wheel. You’ll need basic tools like wrenches, screwdrivers, and potentially a brake spring tool.

Identifying Brake Problems
Before diving into the replacement process, it’s essential to pinpoint the exact problem. The most common signs of failing brakes include:
- Grinding noises: This is often the first indicator of brake wear. As the brake pads or shoes wear down, metal rubs against metal, creating a distinctive grinding sound.
- Slow or unresponsive braking: The mower may continue to move even after you apply the brake, or it may require significantly more pressure to stop.
- Dragging: This is where the brake engages even when you aren’t applying pressure, causing the mower to move slowly or jerkily.
- Loose wheels: A worn-out brake can lead to a loose wheel, creating safety concerns and further damage.
Gathering Tools and Materials
Before starting the brake replacement, ensure you have the necessary tools and materials:
- Wrench set: You’ll need a wrench size that matches the wheel nuts on your mower.
- Screwdriver set: Phillips head and flathead screwdrivers will be needed to remove the brake assembly components.
- Brake spring tool: This specialized tool is used to compress the brake spring during replacement.
- New brake pads or shoes: These are specific to your mower model, so ensure you order the correct replacement parts.
- Gloves: Always wear gloves to protect your hands from dirt, grease, and sharp edges.
- Safety glasses: These will protect your eyes from flying debris.
- Work area: Choose a clean, well-lit area to work on.
