The fitment was direct for my Hornet 3170 gokart frame. The plunger lined up and the brake works flawlessly now. The item showed up fast too!

Took a little bit of coaxing to Prime but worked great after that. Came with banjo bolt and sealing washers. Excellent

Product was easy to install and worked like a charm. Note that there is no instructions included and no video on how to install so you must be familiar with doing so.

Its a good brake master. When I first installed it, a puddle of fluid would appear underneath. I traced it to the resevoir seal. I removed the resevoir and found the rubber seal undernath was pushed in too far in one spot and looked like a finger pressed too hard perhaps during assembly. I removed the rubber seal and re-seated it and reassembled. No more leak so far! Brakes feel firm.

My husband was riding my daughter's Go Kart and he accidently broke the cylinder. This replacement was a perfect fit and she is back on the road again. Her dad is banned from riding her Go Kart anymore :)

I just installed the master cylinder on my kids go kart and it is leaking between the reservoir and the aluminum body. I checked the screws and they were tight. Must be the seals are bad.
