Brake issue

    As you all well know brakes are a serious issue and I seem to be having a slight one with mine. I installed new EBC pads before I rode Tally in April. When I got to Tally I did a inspection of the bike and noticed that the front wheel seemed to barely move when I spun it, only about 3 inches or so. I was thinking that maybe it was just new pads and they needed to be worn in. So today I did the same inspection, for the heck of it, and noticed the exact same thing. Now I probably did a good 80+ laps at Tally so I know the pads are worn in. What else could be an issue here. I would like to see RA in July so I need to get the problem fixed. It's an 07 600RR with braided lines and stock calipers and master cylinder.

    too much pressure in the lines perhaps ... is it just pads u replaced or did u go with lines, new brake fluid, etc.? ... hopefully a techy will hop in here and save my train of thought but that's exactly what it is, just a possible thought of what could be it ... or u just got some BOMB ASS brake pads haha

    good luck

    I had Ken at superbike bleed the brakes at the first barber trackday and then shortly thereafter I changed the pads.

    Check your fluid level in the resivour (sp?). I bet it is now too high. The new pads push the pistons back into the calipers causing the fluid level to rise.

    Too much, and the fluid has no where to go and the brakes act as if they are applied.

    +2 I can attest to this. Did you notice brake fluid on the windshield or elsewhere depending on where your reservoir is located? Sure sign of to much fluid when the fluid heats up and has to expand some of it will come out of the master cylinder compensation port.

    Changed from stock to EBC HH pads?

    No, from Galfer's to EBC's.

    As mentioned don't exceed the max line on the res.

    Also check that your retaining pins on the pads are not worn, gunked up, etc. They should be clean and the pads should freely slide back and forth on them (when the caliper is removed from the rotor). If the pins get worn the pads can get hung up on them and bind. Also, never use any grease on those pins, it atracts dirt and wears the pins prematurely.

    Next check your front wheel bearings, remove both calipers and give the wheel a spin, it should spin freely and easily without any rough feel or grinding sounds.

    Last, make sure your front tire isn't rubbing the fender, some bikes don't have the clearence for the larger than stock but more common front tire sizes.

    Take your calipers off and spin the wheel....

    Narrow it down... Some friction is normal... But 3 Inches?? Not so...

    I'm going to later tonight. I'll let you know how it goes.

    Check the things stated above but also make sure the wheel is mounted in the correct rotation. I remember TDub stating that on some years 600RR there is a little bit of offset in the rotors from side to side and mounting the wheel backwards would cause a ton of drag.

    OBcbr......The front wheel will definitely have an arrow, cast into the wheel for the direction of rotation. As Dave stated, make sure that is correct.

    Yep make sure the wheel is mounted going the correct direction. I have experienced the same thing on a 600RR

    If all the above is good. You may need to clean your calipers.
    Old fluid, dirt etc builds up and prevents free movement of pistons.
    They will extend and not retract.

    Can you over tighten the axle? causing drag?

    Not really, you can over tighten it and cause damage to the bearings, but you'd have to really be careless to do that. The bearings are there to keep the wheel spinning free regardless of how tight the axle is.

    I believe this is common with cbr's. Did you do the same "inspection" before the pad change?
