## Customer Reviews

### ⭐⭐⭐⭐⭐ Modification and bleeding
*by S***A on November 18, 2023*

I just got this and installed it on my kiddos kt 196 coleman go kart. I had to cut the bolt to down to fit. Also on bleeding the brakes. I noticed many complained about this in the reviews. I removed the hose barb on top of the cylinder, and filled the top with fluid, while pumping the brake. It started to lower almost instantly i then replaced the barb, and filled the reservoir. 2 fills yielded fluid out of the bleeder screw on the caliper. Great first test drive and thumbs up from my 6yro.

### ⭐⭐⭐⭐ Works good
*by C***S on May 6, 2017*

### ⭐⭐⭐⭐⭐ Works as intended
*by R***S on September 5, 2024*
