They come with various length settings so users can customize the size and shape of the brake caliper’s spread fingers for optimal performance in any situation.

How to Install and Adjust Spread Fingers on Your Brake Calipers?

Spread fingers are metal components that fit between the pads of a brake caliper and create additional friction when they press against the rotor.

This extra friction helps slow down your car faster and more effectively than without them. Here’s how to install and adjust spread fingers on your brake calipers:

Step 1: Prepare Your Tools

Gather the necessary tools for the job, which include a set of brake pad spreader pliers, an Allen wrench or a socket set, and a flat-head screwdriver.

These tools will be essential for installing and adjusting the spread fingers on your brake calipers.

Step 2: Loosen the Brake Caliper

Use the Allen wrench or socket set to carefully loosen and remove the bolts that secure the brake caliper to the frame. This step is crucial as it allows you to access the brake pads and the internal components of the caliper.

Step 3: Adjust the Spread Fingers

Inside the brake caliper, you will find small metal clips known as spread fingers. These clips play a crucial role in centering and adjusting the brake pads.

Use the flat-head screwdriver to make precise adjustments to the spread fingers, ensuring that they are correctly aligned with the rotor or rim.

This alignment is crucial for achieving even pad-to-rotor contact, which is essential for effective braking.

Step 4: Reposition the Brake Pads

Slide the brake pads back into the caliper, ensuring that they are correctly positioned on either side of the rotor or rim.

Proper placement of the brake pads is necessary to ensure that they can effectively grip the rotor or rim when the brakes are engaged.

Step 5: Tighten the Caliper Bolts

Reattach the caliper to the frame and securely tighten the bolts. It’s important to ensure that the caliper is centered over the rotor or rim. A well-secured caliper is essential for safe and effective braking.

Step 6: Test the Brake Function

Squeeze the brake lever to test the brake function. Check if the brake pads engage evenly on both sides of the rotor or rim.

If you notice any uneven braking, it may be necessary to fine-tune the adjustment of the spread fingers until the braking is consistent on both sides.

Step 7: Final Check

Before taking your bike or vehicle out for a ride, perform a final check of the brake system. Test the brakes at low speeds to ensure they are functioning correctly. This last check ensures your safety on the road.
