Choosing the Right Rim Brake Pads
Before you start replacing your rim brake pads, it’s essential to choose the right ones for your bike. There are several factors to consider when selecting rim brake pads, including:
- Material: Rim brake pads are typically made from organic, semi-metallic, or fully metallic materials. Organic pads are suitable for most road bikes, while semi-metallic pads are better suited for mountain bikes. Fully metallic pads are the most durable but may be too aggressive for some riders.
- Compound: The compound refers to the type of rubber used in the pad. Softer compounds are better for wet conditions, while harder compounds are better for dry conditions.
- Width: Make sure the pad width matches the width of your rim.
- Shape: The shape of the pad should match the shape of your rim.
It’s also important to consider the type of brake caliper you have on your bike. Some brake calipers require specific types of pads, so be sure to check your bike’s manual or consult with a professional mechanic if you’re unsure.
Tools and Equipment Needed
To replace your rim brake pads, you’ll need the following tools and equipment:
- Rim brake pad spacers (if necessary)
- Rim brake pad wear indicators (if necessary)
- Allen wrench or hex key
- Torque wrench
- Pad spacers (if necessary)
- Pad wear indicators (if necessary)
It’s also a good idea to have some cleaning supplies on hand, such as a rag and some brake cleaner, to clean the brake caliper and pads before installation. (See Also: How Much Brake Replacement Cost? Average Prices Revealed)
