swapped out my brembo for a nisin setup with few miles, first the piston/valve at peddle didnt flow so i took it off and blew 20 psi of air through it and now fluid comes through, now fluid comes out the brake end, but zero pressure on the pads, new line should be no air, is there just air in the caliper? do i need a vacuum bleed?, did i possible blow seals out with the air, if somebodys got 5 minutes and knows that they are talking about give me a call asap please thanks tod 60896322nine7 | ||

I always use a vacuum bleed on the rear brakes. You'd be amazed at how hard it can be to get all the air out. | ||

Or bench bleed the complete system. take everything off including lines and lay them on a bench. i vacuum bled mine and i got lucky because it only took one time and they are solid! | ||

I'm not a big fan of the vacuum bleeds - most reliable is the bench bleed method. If you still have spongy brakes make sure you also bleed the banjo bolts. If above fails you may have a bad seal in the master cylinder. Rebuild it and check the condition of the bore. Made a big difference on my front brakes. | ||

What worked for me, perform at your own risk. 1 Fill M/C 2 Place rubber seal and nylon ring from inside M/C cap on M/C. 3 Open bleeder at caliper. 4 Place ring and index finger on nylon ring and hold firm to M/C tank, Press middle finger down slowly into rubber seal. 5 Shut bleeder before you touch bottom of M/C This forced the fluid through the M/C and replacement line on my bike in one slick motion. Did it twice refilling the M/C between and finished with the traditional, pump and bleed. NO problems to date with my rear brake. Oh, hope the nissin has the same cap configuration as the original Buell M/C. As a side note, I do a little work on the side on (BARN BIKES) "the been abandon 3 to 13 years in the barn", then dug out by a fool with big ideas. Some times the orings on the pistons in the caliper stick to the wall of the of the caliper and flex out toward the pads under pressure and snap the piston back when the pressure is released. READ AS REBUILD THE CALIPER. They cant be trusted, not to leak, stick in or out and screw up at the worst possible time. |
