I bought four Brakecrafters kits form my 2005 Suzuki GSF1200 Bandit. Two front brake rebuild kits for the six piston Tokico calipers, One front brake master cylinder rebuild and one clutch master and slave rebuild. The front caliper kits were excellent. When I rebuilt the clutch system I couldn't get the lever to return to a fully out position. After several attempts at ensuring everything was clean and there were no abnormalities in the stock parts that would cause this problem I measured the Brakecrafters master cylinder return spring. It was made of .2mm finer wire and was noticeably softer. The slave cylinder return spring was made from the same diameter wire as the stock spring but was wound with more turns and was again softer. I replaced the Brakecrfters springs with the stock springs and the system worked perfectly. I also had to use the OEM rubber boot on the clutch master as the Brakecrafters one was made of thicker material and pinched when compressed causing a notchy feeling. I will probably return the front brake master cylinder rebuild kit if possible and use Suzuki parts. .
