It seems like some of the Minis from that first year (monos) developed some sticky feeling seals. Try removing the pads & securing the piston that moves freely with a screwdriver. Pump the lever a few times to move the "sticky" piston, but not more than .25" or so exposed....you don't want to pop it out. Take a Q-Tip dipped in brake fluid & clean the sides of the piston cylinder. Use the screwdriver to prise the cylinder back into the caliper body. Repeat this step several times until the piston is moving freely. If you cannot resolve it with this process, you may need to replace the seals....very easy & cheap (~$20)Dr Thunder said:
Sticky Mini caliper--Help please
I'm currently running a Mono Mini (160) on the front of my wife's bike. Recently the caliper has been sticking to the point of making the wheel difficult to turn. It happens very suddenly, and usually squeezing a releasing the brake mulitple times will get it to release. This is the exact same brake that I used to use on my bike, and I would occasionally get some stickiness that caused some unwanted rubbing, etc., but never this extreme. Not long after this starting occurring on my wife's bike I removed the pads and cleaned around the calipers with a Q-tip. This worked for several rides, but now it's started again. What am I missing or failing to do? Thanks for any help.
Oh, and the brake is approximately two years old.
