After fitting new goodridge stainless lines and new fluid, cleaning the disks and scouring the pads the brakes are a little less sharp and the lever is travelling back too far under real sharp breaking. I thouroughly bled 1st the far caliper then the near then the master and repeated no leaks either. Do folks think its worth rebleeding now after riding a couple of hundred miles could the vibration have released some of the stubborn trapped air
Can't hurt to give it a quick bleed after a check for any seepage. Also try tieing the lever back to the bar overnight, just use a cable tie or similar.
+1 for the tying the lever back to the bar overnight. Been there before and the best way to bleed these is either reverse bleed with a large syringe and force it back to the master or get a plastic tube and leave it submerged in a tub of fluid then pump the lever plenty of times then tie it back overnight. That will cure it.
Ok so I normally bleed with clear plastic pipe on bleed nipple submerged in a jar of fluid. With the tying back the lever method Do i do it with the above attatched and the bleed nipple open and is it best done on the master, far or near caliper. many thanks
No fella, the reason for tying it back is that any trapped air with flow back up the open line back to the header tank.
No mate... you do a full, normal bleed exactly as you have done. Then, once you've got it as good as you can, tie the lever back to the bar using cable ties, shut the garage, and open the booze. Come back the next morning, remove cable ties. You should feel a noticably firmer lever, as the last remnants of trapped air have been allowed to move up into the reservoir.
It's good practice to leave the lines under pressure for a bit, better chance of detecting any leaks While the lever is strapped I like to periodically tap the lines too, gives those last pesky bubbles a extra hand to rise up to the reservoir. You guys leave the res cap on or off when strapping down the lever?
Thought so, that's what I do. Seen many peeps keeping the cap off, don't understand that as it will only allow the fluid to absorb moisture ie degrade. BTW this is my bible of brake bleeding http://1000rr.co.uk/index.php?threads/brake-air-bleeding-that-works-for-me.11853/
many thanks folks, did the bleed then strapped back the lever for 24hr fired her up to give some vibration and gently tapped the lines and calipers with rubber hammer. The lever feels way firmer. Just wish the twats from the council would stop gritting so I could get out and test her properly.
