Thank you for choosing Positz V-Brakes to enhance the braking performance of your bicycle. This installation guide will provide you with step-by-step instructions on how to properly install the Positz V-Brakes for reliable and responsive braking. Let’s get started!

Step 1: Preparing for Installation

  1. Ensure you have the Positz V-Brake set, which includes the brake arms, brake pads, and any necessary hardware.
  2. Familiarize yourself with the brake arms and their components. Each brake arm typically consists of a main body, spring mechanism, brake pad holders, and brake pads.

Step 2: Removing Existing Brake System (If applicable)

  1. If you are replacing an existing brake system, start by removing the old brake arms and associated components from your bicycle.
  2. Use a 5mm Allen wrench or appropriate tool to loosen the bolts securing each brake arm to the brake bosses or posts.
  3. Carefully remove the old brake arms and other components, taking note of their position and orientation.

Step 3: Installing Positz V-Brakes

  1. Start by identifying the left and right brake arms. The left arm is typically labeled “L” or has a marking to indicate its position.
  2. Position the left brake arm onto the left brake boss or post, ensuring it is aligned with the rim of the wheel.
  3. Insert the mounting bolt through the brake arm and thread it into the brake boss or post. Tighten the bolt securely using a 5mm Allen wrench or appropriate tool.
  4. Repeat the process for the right brake arm, ensuring it is aligned with the rim and securely fastened to the brake boss or post.

Step 4: Adjusting Brake Pad Position

  1. With the brake arms installed, adjust the position of the brake pads to ensure optimal contact with the rim.
  2. Locate the brake pad holders attached to the brake arms. Loosen the small Allen screws or adjustment bolts on the holders.
  3. Align the brake pads with the braking surface of the rim, ensuring they make even contact and do not touch the tire.
  4. Once properly aligned, tighten the Allen screws or adjustment bolts to secure the brake pads in position. Take care not to overtighten, as it may restrict pad movement.

Step 5: Brake Cable Installation and Adjustment

  1. Install the brake cables onto the brake arms’ cable anchors. This may involve threading the cables through barrel adjusters and noodles if applicable.
  2. Ensure the brake cables are properly tensioned and secured, allowing for smooth operation and responsive braking.
  3. Adjust the brake cable tension using the barrel adjusters to achieve the desired brake lever feel and pad clearance.

Step 6: Post-Installation Check

  1. Once the Positz V-Brakes are installed and adjusted, test the brake system by squeezing the brake levers.
  2. Confirm that the brake pads make even contact with the rim and provide reliable braking performance.
  3. Double-check all the bolts and screws for proper tightness. Ensure there are no loose or rattling components.
