How to Measure a Racing Go-Kart Brake Band?
Want to build the best go-kart on the block? Then you need to know how to measure go-kart brake bands.
A homemade go-kart is more likely to have drum brakes with bands.
If you want to replace the old bands, you will first have their measurements to locate a replacement.
Brake bands for go-karts are relatively easy to measure. The brake band size usually indicates the diameter of the drum brake. Follow the steps below to get done with this task successfully!
Go-Kart Brake Band
Some drum brakes for go-karts come with a brake band. It surrounds the drum brake and attaches to the anchor and brake pins. When you tighten the cord around the drum, it will friction the drum more. The result will be a slower go-kart.

Measuring a Go-Kart Brake Band
There are different sizes of go-kart brake bands. Drum brake bands are usually four, five, or six inches wide.
The drum brake band diameter, not the length, is what determines the drum brake’s diameter. These all use drum brakes that vary in size.
You should know that drum brakes and brake band measurements always refer to diameter, never length.
Go-Kart Drum Brake Bands
As long as the brake drum is within the range of the three-band brake sizes (4′′, 5′′ and 6′′), the brake band fits around it. In that regard, be sure not to measure the length of the brake bands as this won’t work.
Drum brakes for go-karts typically indicate both the diameter and also the kind of brake bands they accept. Note that go-kart brake bands usually specify the diameter of the drum brakes they fit when you buy them online.
- Drum brakes with a diameter of 4 3/16 inches are compatible with 4-inch brake bands.
- Bands of a diameter of 4 3/4 inches will fit drum brakes with a 5-inch width.
- Brake bands with a 6-inch diameter will fit a drum brake with a 6-inch diameter.
Measuring Drum Bands on a Go-Kart
Take the brake band off your go-kart and form a circle to find out if it’s a 4″, 5″, or 6″ brake band.
If the brake band does not fit around a 4 3/16 inch, 4 3/4 inch, or 6-inch drum brake, you should leave ample space at the top.
Experience is necessary, as well as a good eye. Getting the size of your drum break is the best way to measure the brake band on your go-kart correctly. Using this information, you will be able to determine the brake band size of your go-kart.
Standard Band Brake Installation
Brake Band To Frame
Find the brake stud welded to the left rear side of the engine base. Insert a cotter pin through the brake band slot and the brake stud hole and slide the brake band onto the brake stud.
Cotter pinheads should face backward. Backward bend the cotter pin prongs. Fasten the brake band firmly to the spring.
Brake Band To Rod
Brake rods sometimes have bent ends. Go Karts and minibikes use straight brake rods without bent ends, so you must attach the brake band using a Clevis pin.
As soon as the end hole of the brake rod meets the brake band’s loop, position it in the slot to ensure that the brake rod is in the slot. You can slide a flat washer through the brake rod and brake band entirely by placing it on the clevis pin.
Embrace the clevis pin with the cotter pin. Pull the cotter pin prongs apart and bend them backward. Testing the brakes is essential at this time. Turn the drive wheel while applying the brakes fully. Applied brakes cannot cause the drive wheel to turn.
Cotter pinheads should face backward. Backward bend the cotter pin prongs. Fasten the brake band firmly to the spring.
Brake Band and Straight Rod Application
Even though this method is universally applicable, this is yet another Manco single-wheel pull go-kart. It uses a straight-ended rod, bead, clevis pin, washer, and cotter pin with a brake band. You may need to adjust the brake rod itself if the brake does not stop the kart as expected.
Brake Rod Adjustment
Essentially, the brake rod needs to be adjusted if the brake pads aren’t pressing hard enough to control the vehicle. Removing the fastener from the front end of the brake rod and reassembling the connection with the hole on the rear end makes it possible to shorten the brake rod.
You can adjust it the same way as rubbing your back wheels to a halt with Scrub Brakes. You can adjust the brake rod at the back, where it connects to the brake lever.
Final Thoughts
In addition to a coefficient of friction, the brake’s effectiveness also depends on the angle of wrap. While a brake is highly effective with a large workload and requires low input forces to get to high brake forces, it is also prone to changes over time.
If the brake force is higher, the input force is greater if the band material is low. Nevertheless, some low-material alloys display a higher degree of consistency over a wide temperature range.
We hope our guide helped you determine the band brake measurements correctly so that you can run your vehicle optimally!
