Title: front brake drag
Post by: RAISING CANE on February 16, 2007, 12:25:45 AM
Does anyone remove the spring clips on the back of the calipers to allow the pads to not drag the rotors quite as much? I have a GSXR1000 and after I removed the clips the wheel spins much easier. I have read that cleaning the piston seals will help allow the pad to back away from the rotor slightly.I have not done this yet. I herd some of the guys at the track saying they remove the clips to promote freer wheel spin.

Is this somthing that is common or will this cause any problems?

somebody post some pics of this here too if you would be as kind.
i have a little trouble with this on my R1 but on my 929 (my street toy) the front wheel drags real bad and is a biznitch setting down from a wheelie. i just hate to mess with the breaks not knowing 100% for sure what i'm doing.
thanks.

What you where told about the anti-rattle clips was correct. If you don't mind a little noise (dry clutch sound), just toss them in the trash. You are also headed in the right direction with keeping your pistons clean. Should be done at least once each race weekend or sooner depending on your track time. Humid/wet conditions will accelerate the deposit of "crusty" brake dust on the pistons. Remember, when changing a wheel; always clean your pistons "First" with brake cleaner and a soft toothbrush or similar tool before pushing your pistons in for rotor clearance. If you suspect deposits behind the seals, carefully push out your piston out until you see clean surface, then clean and press back in, making sure you are pushing them in square. good luck

Be careful using brake cleaner.  It can dry the seals out on your caliper.  I like a little simple green/water mix with a toothbrush.  Works great.

You are actually better off cleaning the pistons with something other then brake cleaner.

Break cleaner will dry out the seals.
