Removing Old Brake Lines ?

[bccap]

Getting ready to install my new ss lines. Did a search { yes I used titles ! } Lots of good info, but nothing on removing the old lines with minimal mess.
So my questions are :
Where do I start. Pump fluid out through the bleeders as if I were bleeding them ? Or disconnect From the mc ? If I do that will fluid leak from the mc ? Can someone give me a step by step ? I have anti dive brakes.
Also when installing the new lines, do I put crush washers at every join ? Example mc : crushwasher banjo, cw banjo,cw banjo bolt ? Do the crush washers have to face any particular direction ? Or are they the same on both sides ?

You will only get a few drips from the MC when you remove the banjo, but make sure you use some plastic to cover up under the bars (tank/fender/etc)

You can disconnect the lines and use the syringe method to pull the fluid out through the bleeders, or just tie up the old line and open the bleeders (with all necessary tubing) and let it drain for a few hours/overnight. It's pouring rain so I don't think you'll be in much of a hurry to ride today

Did you pick up a MityVac when they were on sale?

Keep some soapy water handy...

I would pull the banjos at the anti-dive and wipe any brake fluid that spills quickly. Put the now free hose ends in a bucket and pump away.

Yes, crush washers at every join - one either side of each banjo. Copper crush washers are real cheap - you'll need 15 (if my maths is right). They are the same both sides.

crush washers

Your new lines should have come with two crush washers for every banjo...You should be able to see them on the existing setup. I'm not sure about the anti-dive, but I would be surprised if they are not there as well as at the splitter

Yup. I got the mit vac. So, if I disconnect from the mc it won't leak except for a few drips inititionally? Then put the miti vac on the anti dive and pump the rest out ?
Not raining here.

I had just changed my fluid before my new line arrived, so I left the M/C full. Mine didn't drip, and it shouldn't if I understand the mechanism correctly.

Hampshirehog makes a good point. If you clear all the old brake fluid out of the M/C (and you should if it's been in old lines for any length of time anyhow) then you don't have to worry about drips...

If I do that will the mc have to be primed. Or just use the miti vac when installing the new lines ? Not sure how to prime a mc.

[hampshirehog]

If you're putting on new lines you should remove all the old fluid really so you will have to bleed everything.

Thanx HH, I will, though I have flushed the lines a couple of times. { just playing with the miti vac } When I was doing my search, someone, I think it was Nessism, said the vac made it unnecessary to prime the mm.

Just unscrew the bottom of the lines, let it run out.
Then take a few pics of the assembly so you remember how it goes back.

Then start rippin **** apart and get messy.
