what a nice master cylinder! I was having trouble adjusting the rear brake on one of my race bikes today and found out that the problem was not in my brake pads cylinder but in my master cylinder that was attached to the foot pedal.

It was very deceiving because when I tap on the slave cylinder where it grabs the disc brake it released so obviously I greased it and cleaned it etc.

Well I came to find out that the problem was in the relief valve inside the master cylinder-so all I had to do is replace it with the new master cylinder and the brakes were like brand-new :-)

So thank you again for selling a product that fits and works.

Sincerely;

Philip
