Default Break bleeding problem...

I changed my front tire a few weeks ago and had to collapse the calipers to get it to mesh with the rotors and noe the brakes are shit. Hardly stopping when pulled all the way in without pumping them. I have tried every method of bleeding I can think of...Any tips?? For those who dont know it's a 06 zx6r

does your master cyl. have a bleeder on it? I would bleed it first then the calipers then the MC again.

if the MC doesnt have a bleeder, use a wire tie, pull the lever in and wire tie it to the throttle tube, leave it on for 24 hrs. you have to leave the cap off, also.

every so many hrs check to see if fluid level had dropped, if so fill back up.

need tires (take offs)? PM me
need a deal on a track day? PM me

disclaimer: I sell used tires (take-offs), these tires have been used at Jennings, Homestead, etc. (road courses for those that dont know) therefor these tires are more used up on the sides than in the middle,

+1. You must use a vacuum bleeder to get all the air out.

here's my guess.


brake dust and dirt builds up in the pistons and when you pushed them back in, the o rings are now rolling the pistons back in the bore when you let off the brakes. it doesn't take much.


buy some brake grease. its this clear shit that doesn't eat the rubber o-rings. most auto part stores sell it for cheap. pull the caliper off, pump the level to push the pistons out. clean them up with brake clean and then lube them up and push them back in.

do that to all of them, bleed normally and you should be straight.

I know brakeclean drys out normal rubber but since brake fluid eats normal rubber I've ever worried about spraying brake clean on calipers.


it may be bad for them, but I've never had trouble with it. just clean and lube them somehow.









brandon likes the stinging when I brake clean down his o rings, so that's why I do it.
