yea. I’m having an issue where the pads arent being pushed back in. gfoing to rebuild the fronts, see if it helps./ take it to a shop, get the brake bled, and all SHOULD be hunky-dory

That should work, unless you fucked something up dropping those 12 o’clock wheelies too hard.

your pistons could just be dirty... Or the MC might have an issue.... I know on MTB brakes, sometimes the exposed part of the piston can get crap on it, and make them not retract smoothly or all the way. A quick clean/wipe can fix it sometimes.

Will be trying the cleaning today.

It can also be the flex lines collapsing not allowing the fluid to leave the calipers.

Just be sure not to use any mineral oils to clean it, or wd-40, as it will damage the seals. Use brake fluid, or alcohol, and of course don’t contaminate the pads.

cool. I just wanted to throw that out there. A lot of people don’t realize how different rubbers arent compatible with different fluids. Can be a potentially dangerous mistake. I am curious what ends up being the problem. I work on brake cylinder testers at work, troubleshooting brake systems is of interest to me.

actually, curious. how to test if the master itself isnt the right size for it?

I’m not a MC designer myself, I just test em, but with just a single piston per wheel it will either be not enough braking power, or the lever will go too far down, right? Not enough braking power would be too big of a diameter MC, and the other would be too small. Assuming the same stroke length. Its just one caliper per Cylinder right? Right hand front, foot back? I’m not a motorcycle rider. If you have a single MC going to front and read calipers, it can get more complicated with different splits(at least in cars).

single piston MC, going to two 4 piston calipers. MC is off a 06 R6, calipers are off a 07 GSX-R 1000
