Thanks for the reply, I tried (yrs ago) the vacuum bleeder on the rear
wheel cylinders, never being able to purge the air, despite numerous times
emptying the bleeder. Since then the brake lines were replaced. Gravity
bleeds over months have improved the pedal firmness but never to the point
of being road safe.

One reason for the spongy pedal is the P-30 master cylinder. If you still
have the OEM brakes, there is absolutely no necessity for installing it.
Originally, when the rear brakes were replaced with a disc system of some
sort, the thinking was that a larger volume of fluid was necessary. With
larger displacement volume comes a lessening of pressure applied for a
given pedal effort. I have installed many disc upgrades, some with P-30
masters, some stock. The stock ones always have a more solid feel than the
P-30's do. If you find that spongy pedal un-nerving, try going back to a
stock one, and see what you think.

Greg,

I have been successfully vacuum bleeding for decades. Many of the things I worked on were simply not amenable to any kind of pressure bleeding and
pedal bleeding takes two people.

Several years ago, this was discussed here at some length and one of the universal facts arrived at was that wrapping each bleeder screw with a turn
and an half of teflon tape makes this process much more successful because it shuts down the air leakage at the threads. Before this, I used to coat
the screws with a teflon pipe thread sealant and that was better than nothing. Tape works much better. (It would also be a much better idea if it
was mine. ) Vacuum bleeds will go better and bleed screws are never corroded in place.

In Michigan (where fender solvent is liberally applied to all the roads from October to April) the rubber caps for the bleeders are also essential for
survival.

Not sure if any of you have used Speed Bleeders, but they come with a thread sealant that is specifically used for this purpose... They also offer
replacement sealant if the factory applied sealant wears off...

https://www.sportbiketrackgear.com/speed-bleeder-thread-sealant/

You can also get it direct from Speed Bleeder.

Not sure if there is anything special about this thread sealant, but unlike the way I usually use thread sealants, it is not installed "wet"... So
normally, I would just brush on the sealant and screw in the fitting.... For the Speed Bleeder sealant, the instructions specifically say let the
sealant dry completely on the bleeder before reinstalling the bleeder into the caliper. So not sure if there is something special about the sealant,
or if it works just because it is installed dry... But it definitely works to prevent leaks past the threads of the bleeder when the bleeder is
open.

From their website:

Clean the Speed Bleeder with soapy water to remove any brake fluid or grease and dry. A hair dryer does this nicely. With the brush cap applicator
apply a small amount of thread sealant evenly to the threaded portion of the bleeder screw. (Leave the first 1 1/2 threads uncoated. This makes it
easy to start threading into the wheel cylinder or caliper without cross threading.) After it is applied, dry with a hair dryer on high setting for
about 1 minute. When cool and dry it is ready for installation.

I got it - I thought it was funny enough to deserve an LOL.

A few others definitions from my collection:

OPERA: Italian word meaning "death by music".

"Fig Newton: The force required to accelerate a fig 39.37 inches/sec."
-- J. Hart

Marriage: The only legal way to exchange money for sex.

Cashtration : The act of buying a house, which renders the subject
financially impotent for an indefinite period.

Reintarnation: Coming back to life as a hillbilly.

Arachnoleptic fit : The frantic dance you perform just after you've
accidentally walked through a spider web.

Caterpallor : The color you turn after finding half a worm in the
fruit you're eating.

and finally: Vocabulary word for the day: Liquidity: When you look at
your investments and wet your pants.

Enjoy!
