2010 MoM work list

[XSokieSPECIAL]

Hey yawl. I have a Mity vac, and another device designed to reverse bleed any hydraulic system, plus I have a few tricks...Brake work is covered.

Damned law students anyway, afraid to get thier hands dirty and leave finger prints somewhere they shouldn't.

DALE.....review the case...I'll be through there sometime thursday evening.

Get stuff cleaned and reassembled and I can help you bleed it or load you up and take you with if you can't get it working.

Provided you don't mind hanging out with a couple old drunks overnight.

Bug, you've just been lucky. No matter how good you are or how well designed the brake system, there will be times that the job of bleeding seems impossible. Then tomorrow, the same system will bleed first time.

What he said.

All I know is I have done COUNTLESS brake jobs over the years and put new lines on god only know how many cars and trucks and bled the lines and the MC on them all without ever using anything more than a piece of tubing and a jar with a small amount of brake fluid in it. But the rear system on these bikes is a complete PITA. Using the Mity-Vac I have done it several times now and even then it takes thinking and working on it.

So Bug, I hope for your sake it goes as easy as you think it will, but if not, well, maybe a little humility can be good for some folks.

I have the stock jets still but I might be getting those 142.5's today

I'll be doing the rear tonight (the whole job that Drake is looking at doing), and I expect to take 1.5 hours from start to finish.

Please be sure to let me know how it goes, how long it took, and what tools you used. Thanks.

Well, I don't know the method you guys use, but this is what works for me on the standard. I just did mine from dry last weekend with new lines. On the front, I'll bleed the farthest in the line first. That's the one at the bottom of the union, going to the left caliper. I hook up the mighty-vac, crank it up to the max, as near 30 in. as i can get it. Fill the M/C, then crack the bleed screw and feed the M/C as it needs while watching the bubble trail at the caliper. When it's clear, close the bleeder. Then do the other caliper.

The rear I do with the M/C off the frame. Same method, but holding the M/C as low as I can helps the air move up the line.

I don't know why you guys have such a hard time with bleeding those things. I just did a front MC/caliper (single disc on a MNS) and bleeding took all of 5 minutes. I'll be doing the rear tonight (the whole job that Drake is looking at doing), and I expect to take 1.5 hours from start to finish. I have never used a mighty-vac. The only one that causes any trouble is the linked line from the rear MC to the front left caliper, but most of you guys don't have to deal with that issue ('81MNS and XJ only). As long as you prime the caliper, and bench bleed the MC, it's super simple.

[DGXSER]

Unless you have a truck and a trailer to pull it down with. If you have the truck, uhaul rents MC trailers pretty cheap around here, $15 a day.

I spent easily three or four hours trying to bleed that system with no luck. I enventually took it all off the bike in one piece, down to my workshop in the basement and set the MC up higher than the caliper and used the Mity-Vac to suck the fluid into the caliper through the bleed screw. That eventually let me bleed it out. But it was a SOB for sure even with the Mity-Vac. Others may know some aciant Chinese secret I don't know about how to do it, but that was my only way to solve it.

3+2+1+1.5+a lot of luck....looks like I'll be holding MoM in Norman.... unless Greg's formula works better.

[DGXSER]

Pulling the parts and opening up the MC and the caliper (use the MC to ump the piston out of the caliper before you pull things apart, and keep fluid in the MC until you have the piston out of the caliper!) About 3 hours maybe. Cleaning both up, a couple hours or so. Putting it all back together if you paid real close attention to the order of parts on the rear MC, maybe an hour or so, putting it all back on the bike another hour or two including new pads.

Bleeding that system without a Mityvac or the like.....?????? How lucky are you!!

[XSokieSPECIAL]

Does anyone have some 145 mains jets??? and would like to trade for some 150 mains?

I have a set of 137.5 stock 79 mains. I'll bring them with me if I can find them.

Just curious, b/c I'm a bad judge of these things. How long will a new guy need to plan on for this pull, clean, swap out the pads while I'm there, clean MC and bleed w/out a mity-vac (can't drop another chunk-o-change)?

I'll probably have to put this off until Wed. or Thur b/c of the time commitment required, so I hope to see you all on Fri.

I took 2 front calipers from a 91 Virago, 2 pistons each, apart and cleaned them and reassembled in approximately 1 1/2 - 2 hours today. Bleeding took about 20 minutes.

If that piston is REALLY stuck you'll need some good air pressure to blow it out of there, or just remove the caliper from the bike and leave the hose connected, take the pads out, and use the master cylinder to pump it apart.

Messy but efficient
