Brake help

just bought a pristine 82' xj750rj Seca and I need your help to bleed the front brakes. I just rebuilt both calipers and the system is now drained. What's the best way to bleed this system with its 4 bleeder valves as well as the remote master cylinder? This is my first Yamaha Seca and I must admit that I'm somewhat apprehensive about completing this final step. Any advice, shortcuts etc to making this project a success would truly be appreciated. Thank you for your time and input (as I look at this complicated machine, I'm quite sure I'll more questions in the near future).

 

The search function is your friend. This has been asked and covered many times.

Welcome to the forum by the way! Pristine 750 seca? We want pics.

 

Thank you for your help... I'll check out the search function for bleeding brakes. Oh by the way how do I get to the search function? Sorry, but I'm just old (69).

What I do to bleed the system.
1. get a large syringe from a farm store and about a foot of vinyl tubing (you can also use a 2-stroke oil mixing syringe).

2. Cut 6" of tubing and attach that to the end of the syringe. Remove the Syringe plunger. You now have a funnel to fill the master cylinder with.

3. Break loose all four bleed fittings (be sure to put down cat litter or drip pans).

4. Tie the brake lever to the grip.

5. Fill the master cylinder and syringe.

6. Wait overnight (or at least a few hours)

7. You should now see brake fluid coming out. Close the bleeders, and untie the brake lever.

8. Bleed the brakes as normal, starting with the anti-dive bleeders, then the brake caliper bleeders. Remove the funnel.

9. You aren't done yet. There will still be some air in the system. The next step cures that, no matter what method you use to fill and bleed the system.

10. Use a vibratory sander (no sanding pad) and slowly run it along the brake lines, calipers, and distribution block from bottom to top. This will move any remaining air bubbles up into the master cylinder. Tap (or vibrate) the master cylinder to get the air bubbles to come out of the return hole. This process can also be done with a box-end wrench or other similar tool, and tapping the calipers and lines (it just takes longer).

11. Do one final bleed normally, just to be certain that the calipers are fully bled.

12. Use a flashlight to check the fuid level in the master cylinder. It should be below the fill neck. Unfortunately there is no dip-stick or sight glass on this master cylinder, so unless you empty it and measure out the fluid you will need to just eyeball it. If the fluid level is too high the brakes can hydrolock and not release.

 

Looks like K-moe has you covered. For the searches, there are two approaches.

First is to use the site search. In the upper right of the screen, there is a search button. Just click in the text box and you can enter your search terms and go from there:



The second way is to use google search. From https://www.google.com/ you can simply enter what you are looking for followed by site:xjbikes.com and it will search your keywords on xjbikes.com only. You can then get a preview of the results and click on the links. See below:

 

Thank you gentlemen, I can now get some sleep tonight without worrying about this brake bleed conundrum. Who says I'm not anal about my motorcycles besides my wife. Thanks again for all of your very helpful input!

 

Oo if you're like me, you won't get any sleep once you figure the google search out and spend all night reading threads on xjbikes.com. I only did that once, I swear.....

 

There's a link or two in my signture that you should look at if you haven't seen them already.

 

Nice write-up @jayrodoh . Should be a "How to" thread!
