Adjusting Bike Brakes Cables

Maintaining Your Bike Brakes

If you’re fond of stopping a moving bike, give your brakes the TLC they deserve, and they’ll make sure you have the braking power you need. Even if you don’t feel like you have a brake issue, regularly going through the steps in this guide can help you spot a problem before it becomes a safety concern.

Step 1: Resources

What you will need is a bike (I hope I didn't need to tell you that...) and a wrench or multi tool. NOTE: This instructable only covers how to tighten loose brakes.

Step 2: Checking the Brakes

Before you go ahead with the rest of my instructable, check to make sure your brakes are loose and need tightening. Perhaps they need another form of repair such as pad replacement or wire replacement. If are worn away or the wire is stuck, look elsewhere, if your brakes, however, just need tightening, continue.

Step 3: Finding and Loosening the Brake Screw

Pick a brake (Front or back) to start with. I chose the front for this instructable. Locate the screw I have linked in the image. It should be fairly similar to my image. Find a wrench that will fit it and loosen it but do not take it off or you will have a hard time later.

Step 4: Tightening

Pull on the wire to the desired brake strength. Be sure to spin the wheel after tightening the screw a bit to see if it squeaks. If it does, re-position the wire a bit. If it doesn't squeak, make sure the brakes make contact when you pull the brake handle. When you think its fixed, take the bike for a spin and see if this is what you wanted.

Step 5: Good Brakes

If you followed my steps, your brakes should now be strong. Thank you for reading my first instructable and I hope to see you in others. -Bill Moody
