misscrabstick Posted December 27, 2019 Share Posted December 27, 2019 Get a syringe with a bit of pipe on it, try pushing fluid through the bleed nipple, make sure the master cylinder can fully travel to the off position, if the piston can't get fully off then it's possible the feed hole is covered by it. Might be the cylinder seals are shot. Quote Link to comment Share on other sites More sharing options...
cleanorbust Posted December 28, 2019 Share Posted December 28, 2019 I had problems getting mine fully bled until I used an extra large syringe. Seemed this generated extra pressure which purged all the air which a small syringe could not. Quote Link to comment Share on other sites More sharing options...

section swept Posted January 10, 2020 Share Posted January 10, 2020 Leaving the brake lever/pedal under pressure overnight can produce a more solid feel when operated as the overnight under pressure will cause any microscopic air bubbles to find their way to the fluid reservoir, thus producing a more positive feel!
