Got two of these because the first one that arrived had a leaking caliper.
I took the caliper on the first brake apart and found that the hose banjo o-rings attachment were leaking because there were some metal filings/shavings in the bore where the banjo bolt screws in. Strange, but Wheel and Sprocket sorted a replacement quickly.
On both brakes, the pad spacer that comes in the caliper was so firmly attached that I had to attach the caliper to the bike's brake mounts and tap it out with a hammer and punch.
Also, beware that if you have to cut the hose, you will need to purchase a SRAM stealth-a-majig barb separately. The barb that comes in these brakes is a press-in type (not the normal threaded, T8 torx head style, like the standard stealth-a-majig barb). It is installed at the 2000mm hose length and can't be removed and re-installed. The red compression fitting from the stealth-a-majig is included, you will just need a new threaded barb.
Overall these brakes are still a steal at the $54.95 price.
