Dear Hayes, I am very disappointed with the design of your design of your brakes on my mountain bike. I have hayes hfk 9 brakes and the design on them is horrendous. I am very dissapointed with these brakes because all they do is hassle me. I constantly have to re tighten the lever adjustment screw on them after rides. These brakes are extremely dangerous because if you are riding for a long time and if the screw backs out due to vibrations you could be seriously injured do to loss of braking power. I strongly suggest that you make the brakes so that the screw does not back out due to vibrations. I really think that these brakes should be taken off of the market and riders should be offered a refund for their brakes or all hayes hfx-9 brakes master cylinders should be put on recall and they should be professionally repaired by a local bike shop that sells these brakes. Please take my suggestions seriously and please give me some respnose as to what to do about these brakes. John Muldoon
Their response was.....Hi John,
Thank you for your email.
We now have a two-piece adjuster bushing with a nylock insert that will keep your lever adjustment dialed to the desired position. I will drop a set in the mail for you.
