Help! No BRakes

I just rebuilt both calipers and reassembled them. A mechanic suggested using some grey antiseize, so I used some when I reassemled. Then used a large C clap to push the cylinder back in. Once on the bike I bleed the brakes until clear fluid came out and no bubbles. I also,while bleeding the brakes forgot to due the anti dive so more bleeding! The cylinders wont come out! They will move when I squeeze the handle but go back in. After 5 beers and almost a full bottle of brake fluid, the left cylinder is out further than the right. On my 6th beer writting this, any suggestions?

SECA 750

 

Try tieing the brake handle closed over night. I have no idea what it does but it worked for me. All I can think it might do is break in the new seals. Hope it helps you cant hurt to try.

 

I will give it a try. Out of beer anyway!

 

rule no 1 no alcohol when working on machinery. the thought process goes out the window.
next i just replaced my front brakelines with steel braided lines, bled the system and whilst getting clean brake fluid from the calipers i had no brake pressure. cracked the banjo fitting at the master cylinder and presto a vapour lock had formed, once bled there i went back to the calipers and made sure there was no more air in the system and all is right with the world again.
i now have excellent front brakes with a one finger application.

hope this helps you some

 

You still have trapped air. I just rebuilt my caliper and it can be frustrating as all get out to get it completely bled. Letting it sit helps; I suspect that because the caliper walls are not SMOOTH smooth but have fine machining grooves left they trap micro-bubbles.

Once you get enough lever back to be able to safely ride the bike, a few heat cycles help too. Re-bleed after you get the brakes hot a few times.

I use a combination of Mity-Vac and old-school bleeding.

 

I had the same problem bleeding my "hidden" master cylinder.
I used a long, clear tube, and sucked the fluid out of the calipers, then the anti-dive bleeders.
Having a bleeding jar would be easier.

 

Well jeez...I don't know why anyone would put five beers and a bottle of brake fluid into the brake system... :lol:

I second this - tho it's not a banjo fittnig on the master cylinder of the xj750 seca, it's a solid steel brake line. You have to take the headlight off, and you'll make a mess, so either take the fender off or cover it real good. Squeeze the brake handle and crack the line, then tighten it and release the handle.

 

Thanks for all the help! I could have sworn I read somewhere to put the beer and brake fluid in there! I guess you cant believe everthing you read on the internet! I guess in my haste , sorry brunken haste, I forgot to mention that I have a bar mounted master and stainless steal braided lines. I tied the brake lever closed over night, then I opened up any banjo fitting till some fluid came out, then continued to bleed. It has gotten a lttle better there is some contact. I will try this procedure on friday.
