How to Adjust Brakes on a Schwinn World Sport Bike

Although an older model, the Schwinn World Sport Bike employs much the same technology as today’s road bikes. The World Sport's side-pivot brakes aren't very different than modern dual-pivot brakes, and are just as easily adjusted. Brakes need to be adjusted when the cable that connects the brake lever to the actual brake has stretched to the point that greater force is now required to achieve adequate braking. Adjusting the cable will solve this issue.

Things You'll Need

• Allen wrench (5 mm or less, depending on model of brake)
• Needle nose pliers
• Toe strap (or other device to hold the brake pads against the rim)

Instructions

1. Loosen the anchor bolt that secures the brake cable to the body of the brake, using a proper size Allen wrench (5 mm is common on most brakes).

2. Turn the cable barrel adjuster counterclockwise until it is almost fully backed out. This barrel adjuster is located where the cable enters the body of the brake. Backing out the barrel adjuster now will allow you to fine-tune cable tension later on.

3. Squeeze the brake pads against the sides of the rim. The brakes will need to be held in this position while you pull the cable taut and simultaneously tighten the cable anchor bolt. This is a three-hand job, so either enlist a friend's help or improvise a strap to tighten over the brake pads and around the wheel so that the pads are clamped onto the wheel. A pedal toe strap often works well.

4. Pull the end of the brake cable taut (while the pads are clamped onto the wheel) using a pair of needle nose pliers. Simultaneously tighten the cable anchor bolt onto the cable.

5. Remove the toe strap (or other device) from around the brake pads. Adjust the proximity of the brake pads to the wheel, by turning the cable barrel adjuster in toward the body of the brake. Aim for 3 mm to 4 mm of clearance between each pad and the side of the rim.

6. Repeat the above steps for each brake.
